The SCOPE of the INVENTION

[0001] the Present invention relates to the field of communications technologies, and in particular, to a method, system and device for aggregation of radio networks.

The LEVEL of TECHNOLOGY

[0002] In the development process of mobile networks due to the limitations of the various terms appearing broadband mobile networks and conventional networks will coexist for a long time. For example, when the network is a Universal Mobile telecommunications System (Universal Mobile Communication System UMTS), initiated by the organization of the partnership project 3rd generation partnership project 3rd generation 3GPP), is developing a network of long-term project development (project long-term development, such as LTE, UMTS and LTE will coexist for a long time.

[0003] mobile communications Network consists of a network radio access network radio access, RAN) and core network (core network, CN). The user equipment (user equipment, UE) accesses the core network through a radio network access via an air interface. The air interface is closely linked with the technology of radio access technology radio access, RAT)used by the mobile communications network. To better describe the mobile communication network corresponding to the technology of radio access, hereinafter referred to as a radio network. UMTS and LTE are two different technology and radio-access and the radio network, the corresponding UMTS and LTE, referred to as UMTS and LTE, respectively. The transmission channel, the user equipment sets on the radio, referred to as radio access. One transmission channel is a unidirectional channel (One channel) radio technology access, for example, unidirectional channels in the UMTS and LTE networks are referred to as unidirectional channels UMTS and unidirectional channels LTE, respectively.

[0004] In the process of development from a UMTS network to the LTE network the number of users and data traffic in LTE networks are gradually increasing in the LTE network, while the secondary user transmission rate decreases. However, when the number of users and data traffic on the UMTS network is gradually reduced, the spectrum UMTS network is reduced. Therefore, in the process of migrating from a UMTS network to the LTE network spectrum resources in UMTS network must be used effectively to prevent the reduction in user experience due to overloading of the spectrum LTE network from the middle to the last period of the migration.

[0005] to prevent the above problems, use the method for transmission by aggregation of radio networks, i.e. multiple radio accesses one of the user equipment are aggregated, which ensures that the initial resources UMTS mo the ut to be fully used, and prevents problems such as makanannya interference and interference adjacent channel between network systems. Method for aggregation of radio networks includes: providing mobile access router (router mobile access, MAR) on the user side, where the mobile access router aggregates the communication lines of different technologies of radio access on the user side, such as radio UMTS and WLAN, and serves for a destination Internet Protocol (Internet Protocol, IP) of each radio line in the direction of the ascending line of communication and to provide each user terminal access to the data through the local network; and the introduction of the device proxy server MAR (proxy server MAR) on the network side, where the proxy server MAR is used to assign IP packets each radio line in the direction of the descending line.

[0006] However, in this solution for aggregation of radio networks should be introduced such functional features as a router MAR and proxy server, which increases the system complexity and costs. Another method for aggregation of radio networks proposed by the 3GPP organization can simplify the structure of the network system. In particular, at least one filter routing (filter routing) is configured at the user equipment and the network gateway packet data network packet is data, PDN), respectively, where the configured filter routing includes such attributes as the source IP address/destination port number, source/destination, and Protocol type, and used to match the flow of the IP packets of the same characteristics; the user equipment configures IP addresses that are associated with each radio access (including non-3GPP radio access and the 3GPP radio-access) as different addresses to send address to send, CoAs); each radio access passes through the PDN gateway, where each filter routing gateway PDN address matches for transmission. Thus, in the direction of the downlink PDN gateway routes the flow of the IP packets, coordinated through the filter routing network corresponding to the address for transmission; similarly, in the direction of the ascending line filter routing of the user equipment performs the control of the discharge flow of the IP packets.

[0007] the Method for aggregation of radio networks proposed by the 3GPP organization, applies to the aggregation of non-3GPP and 3GPP radio-access. In addition, in the process of aggregation of radio networks radio access in the areas of uplink communications and downlink are fixed. Therefore, the resources of each radio can't be used properly.

DETAILED DESCRIPTION of embodiments

[0029] the Technical solution provided in embodiments implementing the present invention, the below described clearly and completely with reference to the accompanying drawings. Obviously, implementation options described below are exemplary, not covering all embodiments of the present invention. All other variants of implementation, which averages experts in this field technicians receive on the basis of embodiments of the present invention without creative efforts, are also within the scope of the present invention.

An implementation option 1 method

[0030] the Method for communication with the aggregation operation is used to aggregate different radio access using a uniform basic network packet, such as aggregation access UMTS radio access LTE. the moreover, the user equipment can access the underlying network packet through at least two different radio interface. The method provided in this embodiment, is a gateway between homogeneous base packet and the external network packet, i.e. the PDN gateway. As shown in Fig. 1, the method includes the following steps:

[0031] Step 101: Obtain the location information of the user equipment in at least two radio networks.

[0032] In this embodiment, the user equipment accesses the core network packet via at least two radio interface, i.e. unidirectional channels of at least two radio technologies-access is established between the user equipment and a PDN gateway. Information location may indicate the current location of the user equipment in the radio network, and information location may be information ID of the current cell of the user equipment, information of the ID field of routing, where the user equipment is located, the information identifier of the tracking areas, where the user equipment is located, or other information.

[0033] In the processes, which the user about what the equipment is designed applies to the radio and sets, modifies or removes unidirectional channels of a radio network, a network gateway service access sends the information of the current location of the user equipment to the PDN gateway, wherein the network gateway service access service network node through which the user equipment accesses the core network packet, such as the serving GPRS support node (Serving GPRS Support Node, SGSN) in a UMTS network, the Control Object Mobility (Mobility Management, MME) in LTE network and the serving gateway (Serving Gateway S-GW). Therefore, the PDN gateway may receive the location information of the user equipment from the network gateway service access.

[0034] Step 102: Obtain, according to the location information, the network load of each radio network, where the user equipment is currently located.

[0035] Information network load of a radio network, where the user equipment currently is located, may be information such as the number of active users, the frequency of the network load and bandwidth or data transfer rate for data transmission to the radio network, where the user equipment is currently located.

[0036] In the mobile communication system for supporting the operation (system support and operations OSS) is a platform for comprehensive management and maintenance work. Related to the network information stored in the system OSS, including status information, such as information network load. The PDN gateway may request that the OSS in relation to the information network load corresponding to the area specified by the information location of the user equipment.

[0037] Step 103: Determine, according to the network load and a predetermined policy, the way in which the data streams of the user equipment is transmitted using at least two radio technologies-access.

[0038] the Preset policy may include one or multiple parts of the following information: the scaling factor of the traffic between the first network and the second network is a specified value; some data is streamed through the use of some technology radio access directions uplink communication and downlink, for example, the data uplink communication and downlink some TCP connections (TCP, TCP) are transmitted through the use of some technology radio access; the number of network users in the corresponding area of the first radio network is less than the preset value; the data flows upward communication is elizavetinskaja equipment are transmitted preferably through the use of the second technology radio access and when the data rate of the second radio network is less than the preset value, the data streams downlink are transmitted by using the first radio technology access.

[0039] it is Clear that the PDN gateway may consider only the actual load on the network to determine the way in which data streams are transmitted through the use of technology radio access, which provides that the requirements in the predetermined policy may be satisfied after the data streams of the user equipment transmitted through the use of a unidirectional channel of appropriate technology radio access so that load balancing between each radio network was implemented.

[0040] the PDN Gateway may consider not only the actual network load, but also the information of the data flow of the application layer of the user equipment, i.e. the PDN gateway may consider other information, such as data transfer on the basis of the actual requirements of the user equipment, to determine the way in which data streams are transmitted through the use of technology radio access, which ensures that not only the requirements in a pre-defined policy, but also the actual requirements of the user equipment can be meet the s after as the data streams of the user equipment transmitted through the use of a unidirectional channel of appropriate technology radio access. Thus, load balancing between each radio network can be implemented, and the requirements of quality of service of the user equipment can be satisfied.

[0041] the Way in which the data streams of the user equipment is transmitted using at least two radio technologies-access, which is defined by the PDN gateway may include: what technology radio access and what a unidirectional channel technology radio-access is used to transmit each data stream ascending line and each data stream downlink user equipment.

[0042] the Information of the data flow of the application layer of the user equipment refers to information such as the maximum allowable transmission rate in the transmission, the full amount of data and the maximum allowable delay data streams uplink communication and downlink, which must be passed. The user equipment may receive information of the data flow of the application-level using the messages application-level during the creation of a session (Session), for example, it receives information on the eye-level data application using message initiation Protocol session Initiation Protocol Session, SIP), using log messages to a file transfer Protocol (File Transfer, FTP) and hypertext transfer Protocol (Hypertext Transfer Protocol, HTTP); the PDN gateway may receive information of the data flow of the application layer of the user equipment by requesting object function policy and charging rules (the Object Function Policy and charging Rules, PCRF) or through the use of built-in function deep view packages (Deep View Packages DPI) gateway PDP.

[0043] Step 104: Send the data streams of the user equipment in such a specific way.

[0044] it Should be noted that the PDN gateway may configure unidirectional channel of each radio technology access in the direction of the ascending line and/or downlink to the user equipment according to a specific path, which data streams are transmitted through the use of each technology radio access, that is, what technology radio access and what a unidirectional channel technology radio-access is used to transmit each data stream ascending line and/or each data stream downlink user equipment. Thus, in the direction of the downlink PDN gateway transmits data streams downlink Paul is outerscope equipment according to configurable unidirectional channel technology radio access in the direction of the downlink; in the direction of the uplink communication of the user equipment transmits data streams uplink communication of the user equipment according to configurable unidirectional channel technology radio access in the direction of the ascending line.

[0045] As described above, when aggregating radio networks in this embodiment of the present invention, the PDN gateway receives information network load of each radio network, where the user equipment is currently located, according to the location of the user equipment in at least two radio networks, and determines, according to the network load and a predetermined policy, the way in which the data streams of the user equipment is transmitted using at least two radio technologies-access, and finally transmits the data streams of the user equipment in this certain way. Therefore, the amount of data transferred through the use of each technology radio access, is assigned properly in the aggregated network according to the actual load conditions of the network, so that the resources of each network in an aggregated network were effectively used.

[0046] the Method for communication with the aggregation operation in this embodiment of the present izobreteniya the transfer method, through the use of which the user equipment accesses the core network packet via at least two radio interface. In a particular embodiment, before step 101, the PDN gateway then performs the following steps:

[0047] Step 100: Set unidirectional channels of at least two radio technologies-access with the user equipment, and to keep the information identifier of the user equipment and the identifier information of unidirectional channels of these at least two radio technologies-access.

[0048] Installed unidirectional channels of technology radio access refer to the data channels based on the radio access technologies that are established between the user equipment and the base packet after the user equipment has joined the radio. In particular, unidirectional channels can be set by using any one or multiple of the following ways: the user equipment establishes a single connection PDN unidirectional channels multi-technology radio access gateway, PDN, that is, the user equipment establishes, through the PDN gateway, a single PDN connection, which takes unidirectional channels set the state of technology radio access; the user equipment establishes a unidirectional channels of different technologies radio access with multiple PDN connections, that is, one part of the PDN connection established by the user equipment via the PDN gateway, receives unidirectional channels of a single technology radio access, while another part of the PDN connection established by the user equipment via the PDN gateway, receives unidirectional channels other technology radio access.

[0049] it Should be noted that in the process of establishing a unidirectional channels in this embodiment, when the PDN connection is established, unidirectional channels multi-technology radio access installed the same user equipment, use the same address PDN, that is, the same IP address, which prevents the waste of resources addresses.

[0050] After unidirectional channels are set, the PDN gateway can manage, quasi-static method and/or dynamic way, the distribution of data streams that must be passed through the reception of each radio access technology. Details are as follows:

[0051] (1) data Flow control quasi-static way: when data flow control, the PDN gateway distinguish, using the template of the traffic flow (the flow pattern TP is fika, TFT) and/or PDN connections, unidirectional channels each technology radio access established between the user equipment and a PDN gateway.

[0052] In this embodiment, the PDN connection can be used to distinguish between unidirectional channels of different technologies radio access. In particular, when the user equipment establishes multiple PDN connections through the PDN gateway, the following can be configured: user equipment adopts various technologies radio access for different PDN connections, for example, the user equipment establishes five PDN connections through the gateway PDN, where three of the PDN connection of the user equipment accepted the technology of radio-A access, while the other two PDN connection of the user equipment accepted the technology of radio-B access.

[0053] a Unidirectional channels of different technologies radio access can be distinguished using patterns of traffic flow. To distinguish the data streams transmitted over a unidirectional channels, from the data packets at the application layer, each unidirectional channel corresponds to one TFT. TFT is a group of packet filters (filters packets, where each packet filter may include such attributes as the source IP address/destination, Protocol type, and range for the tov, and is used to coordinate and share data flows with the same characteristics. In particular, when the same PDN connection that the user equipment sets through the PDN gateway has multiple data streams, the following can be configured: different data flows in the PDN connection between the user equipment and PDN are transmitted through the use of various technologies radio access. Because these data streams correspond to different TFT, they can be distinguished from data packets of the application layer and transmitted through unidirectional channels of appropriate technologies radio access.

[0054] Regardless of distinguished whether unidirectional channels of different technologies radio-access PDN connection or through the TFT, the PDN gateway may manage a quasi-static way data flows through each technology radio access when step 103 is performed. In particular, this can be implemented using the following step A1 or step B1:

[0055] Step A1 is Determined only according to the network load, obtained in step 102, and a predetermined policy, the pattern of traffic flow TFT and technology radio access, which correspond to the unidirectional channel used to transmit data flow of the user equipment in the direction of the sun is odawa lines of communication and/or direction of the descending line.

[0056] In the process of establishing a unidirectional channel, the user equipment transmits the ID technology radio access corresponding unidirectional channel request unidirectional channel. Therefore, the PDN gateway knows the technology of radio access, the corresponding unidirectional channel established between the PDN gateway and the user equipment, the user equipment also knows the technology of radio access, the corresponding set of unidirectional channel.

[0057] In this case, the PDN gateway according to the actual network load and a predetermined policy may define the way data flows upward communication and/or downlink transmitted through the use of technology radio access. Thus, after the data streams of the user equipment is transmitted through the use of a unidirectional channel of appropriate technology radio access requirements in advance of a given policy can be satisfied, and load balancing between each radio network can be implemented. Predefined policies described in step 103, and are not further described.

[0058] the Method of transmitting a data stream defined by the PDN gateway may include: data flows transmitted in the directions of the upward communication line and Nisha is the present line, where each data stream corresponds to one TFT; and a unidirectional channels of technology radio access used for streaming data.

[0059] Step B1: Determine, according to the network load information of the data flow service level of the user equipment and a predetermined policy, the pattern of traffic flow and technology radio access, which correspond to the unidirectional channel used to transmit data flow of the user equipment in the direction of the ascending line and/or the direction of the descending line.

[0060] it is Clear that, when the way in which transmitted data streams of the user equipment in the direction of the uplink communication and downlink, are defined, the way in which transmitted data streams may be determined according to the actual information load in the current network, and based on data requirements of the user equipment. Thus, after the data streams of the user equipment is transmitted through the unidirectional channel of appropriate technology radio access, not only in the predetermined policy may be satisfied, but also the actual requirements of the user equipment can be satisfied. Therefore, load balancing between the AC the DOI network can be implemented and requirements of quality of service of the user equipment can be satisfied. Predefined policies described in step 103, and are not further described.

A method of transmitting a data stream defined by the PDN gateway may include: data flows transmitted in the directions of uplink communications and downlink, where each data stream corresponds to one TFT; and a unidirectional channels of technology radio access used for streaming data.

[0061] After the way in which transmitted data streams, defined quasi-static way, when the transmission of the data stream at step 104 is performed in the direction of the downlink, the PDN gateway transmits data streams downlink user equipment configured according unidirectional channel technology radio access in the direction of the descending line; in the direction of the uplink communication of the user equipment transmits data streams uplink communication of the user equipment according to the configured unidirectional channel technology radio access in the direction of the ascending line.

[0062] it Should be noted that, when the data flow is controlled quasi-static way, one-way channel of the same technology radio access should use is to find, to transmit the same data stream, i.e. the stream data uplink communication or downlink of the same TCP connection. This prevents the loss of TCP performance caused by large differences between the delays of the transmission, when the same data stream is transmitted through the use of various technologies radio access.

[0063] (2) data Streams manage the dynamic way: in a dynamic way unidirectional channels of different technologies radio access corresponding to the same PDN connection that the user equipment sets through the PDN gateway may accept the same TFT.

[0064] in Order to control the data flow dynamic method, the PDN gateway determines only the way in which data streams are transmitted in the direction of the downlink, while the way in which data streams are transmitted in the direction of the ascending line is determined by the user equipment (described in the following Embodiment 2). In this case, when determining the way in which the data streams of the user equipment is transmitted using at least two radio technologies-access in the direction of the downlink, the PDN gateway may determine the amount of data or the proportion of the amount of data for data streams transmitted p is by means of using a one-way channel of each radio technology access in the direction of the downlink. Step 104 may be implemented in the following stages:

[0065] Step A2: to Choose, according to the specified data volume or proportion of the amount of data, technology radio access used for streaming data to a user equipment in the direction of the descending line.

[0066] Step B2: Send the data streams of the user equipment in the direction of the downlink by using a unidirectional channel selected technology radio access.

[0067] it is Clear that when the PDN gateway selects technology radio access, data volume or the ratio of the volume of data streams transmitted by using each technology radio access in the direction of the downlink must match the data volume or the ratio of the amount of data that the PDN gateway determines according to the network load.

[0068] As shown in Fig. 2, TFT1 gateway PDN coordinates and separates the data streams downlink user equipment 1, while TFT2 coordinates and separates the data streams downlink user equipment 2. After the amount of data streams transmitted through the use of technology 1 and/or 2 radio access in the direction of the descending line, determined by the dynamic method, the object selection function radio technology the technology selects, according to a particular amount of data flows transmitted in the direction of the downlink, the technology of radio access, which is used to transmit streams of data downlink, and transmits the data streams downlink user equipment through the use of a unidirectional channel selected technology 1 and/or 2 radio access.

[0069] it Should be noted that, when data streams manage a dynamic, unidirectional channels of different technologies radio-access can be used to transmit the same data stream, i.e. the stream data uplink communication or downlink of the same TCP connection. Thus, the traffic of the user equipment on various radio access networks can be managed dynamically and flexibly.

[0070] As unidirectional channels of different technologies radio dynamic access method can use the same TFT, the PDN gateway may configure the same TFT for unidirectional channels multiple different technologies radio access so that unidirectional channels to transmit data flows with the same QoS requirement. This prevents the loss of TCP performance caused by large differences between the delays of the transmission, when the unidirectional what's the different channels of technology radio access used to transmit the same data stream, i.e. the stream data uplink communication or downlink of the same TCP connection.

[0071] In this embodiment of the present invention the user equipment accesses the core network packet via at least two radio interface. In this case, the user equipment is in the communication state with the aggregation network; user equipment may withdraw from the radio and to access the underlying network packet through only one radio interface. At this time, the user equipment is in the status transmission over a single network.

[0072] In another specific embodiment, the user equipment can be switched between the state of transmission over a single network and a communication state with aggregation networks. Details are as follows.

[0073] (1) Assuming that the user equipment is currently located in the first radio network, the user equipment can be switched from a state of transmission over a single network transmission status with aggregation networks in the following cases, that is, the user equipment attached to the network different from the first radio network, for example, the second radio network.

[0074] a1. Custom the new hardware automatically permits the transfer function with aggregation networks.

[0075] b1. The user equipment does not prohibit the transfer function with the aggregation network; user equipment transmits data streams by using only technology 1 radio access due to factors such as network coverage; user equipment re-enters the coverage area of other wireless networks.

[0076] c1. The user equipment does not prohibit the transfer function with the aggregation network; user equipment leaves the radio 1 due to network congestion of the radio network 1 (or other factors); user equipment must restore the unidirectional channel radio network 1, when the reason for getting user equipment from the radio 1 is fixed.

[0077] In cases a1 and b1 user equipment initiates a join query to the second radio network. After basic packet receives a join query, it sets a unidirectional channel of the second radio technology access between the PDN gateway and the user equipment. In the case of c1, the PDN gateway is requested to detect the actual condition of the second radio network, for example to detect whether the load network to the second radio network within a specified range; if so, the PDN gateway establishes a unidirectional channel of the second radio technology-DOS the UPA with the user equipment.

[0078] (2) User equipment can be switched from a state of transmission aggregation networks in the transmission status on the only network in the following cases:

[0079] a1. Custom hardware automatically disables the transmission function with aggregation networks.

[0080] b2. The user equipment leaves the coverage area of any radio network because of the movement of the user equipment.

[0081] c2. The user equipment is unable to communicate across the network due to factors such as the radio is faulty or the user equipment enters a dead zone radio network.

[0082] d2. The user equipment must come from the radio due to factors such as network congestion of the radio network, where the user equipment is located.

[0083] In the case of a2, the user equipment initiates a detach request to the radio network; in the case of b2, if the user equipment detects that the signal strength of the radio network is less than the specified threshold, the user equipment initiates a detach request to the network; in the case of c2, the network initiates the detach request of the user equipment to another radio network. When the PDN gateway receives the detach request, the PDN gateway removes the unidirectional channel user about the equipment in other networks.

[0084] In the case of d2, the PDN gateway may detect whether the network load any radio network, where the user equipment is located, the specified range; if so, the PDN gateway removes the unidirectional channel radio network.

An implementation option 2 ways

[0085] the Method for communication with the aggregation operation is used to aggregate different radio networks using homogeneous base packet, for example radio network UMTS and LTE. In addition, the user equipment can access the underlying network packet through at least two different radio interface. The method provided in this embodiment, is a user equipment. As shown in Fig. 3, the method includes the following steps.

[0086] Step 201: to Discover the way in which the data streams of the user equipment is transmitted, through the use of at least two radio technologies-access in the direction of the descending line.

[0087] it is Clear that the dynamic method is used to control the data flows upward communication through various technologies radio access. Because the user equipment cannot receive the appropriate conditions of network load, when the user equipment performs dynamic is the Board traffic flows in relation to data flows upward communication the way a reverse synchronization can be used, that is, the way in which data streams are transmitted by using at least two radio technologies-access in the direction of the descending line is detected, such as a unidirectional channels of technology radio access used for streaming data downlink, the received user equipment.

[0088] the Way in which the data streams of the user equipment is transmitted using at least two radio technologies-access in the direction of the downlink is determined by the PDN gateway dynamic way and according to the information network load at least two radio networks, where the user equipment is currently located. A specific method for determining, as described in Embodiment 1, and are not further described.

[0089] Step 202: Determine, according to the detected path, the path that the data streams of the user equipment is transmitted using at least two radio technologies-access in the direction of the ascending line.

[0090] When the way in which data streams are transmitted in the direction of the ascending line is defined, the user equipment may determine, according to the proportion of the amount of data transmitted through the IP is the use of at least two radio technologies-access in the direction of the downlink or according to predefined relationship calculation, the way in which the data streams of the user equipment is transmitted in the direction of the ascending line. For example, the proportion of large amounts of data through the use of at least two radio technologies-access in the direction of the descending line is used as the proportion of large amounts of data through the use of at least two radio technologies-access in the direction of the ascending line; or the proportion of large amounts of data through the use of at least two radio technologies-access in the direction of the upward communication line, an equal proportion of large amounts of data through the use of technology radio access in the direction of the descending line, multiplied by a scaling factor, where the scaling factor can be configured in the user equipment or dynamically configured a party to the network using a alarm.

[0091] it Should be noted that as the technology of high speed packet access (high Speed Packet Access, HSPA) has a bad transmission performance uplink communication and the low efficiency of transmission, the user equipment does not use HSPA to transmit user data in the direction of the ascending line, but uses HSPA, the button to transmit signaling, L1, L2 or L3, and so on, necessary for the air interface. Thus, when the data flows upward communication is transmitted, the energy consumption of the user equipment can also be reduced.

[0092] Step 203: Send data streams uplink communication of the user equipment from the corresponding radio network to the core network packet in this certain way.

[0093] As is known from the above, in the transmission with the aggregation operation in this embodiment of the present invention the user equipment determines, according to the detected path, which data streams are transmitted by using at least two radio technologies-access in the direction of the downlink, the way in which data streams are transmitted by using at least two radio technologies-access in the direction of the upward communication line, and transmits the data streams uplink communication from the radio network to the core network packet in such a specific way. Since the information data flow of the user equipment in the direction of the downlink is assigned properly according to the actual load conditions of the network, the resources of each network in an aggregated network effectively used.

[0094] Ways is to send with the aggregation operation in this embodiment of the present invention is a transmission method through the use of access of the user equipment to the core network packet through at least two radio interface. In a particular embodiment, before step 201 the user equipment further performs the following steps:

[0095] Step 200: to Establish a unidirectional channels of at least two radio technologies-access to a PDN gateway.

[0096] When the user equipment establishes a unidirectional channels with a PDN gateway, it can use any one or more of the following ways: the user equipment establishes a single connection PDN unidirectional channels multi-technology radio access gateway, PDN, that is, the user equipment sets through the PDN gateway one PDN connection that takes unidirectional channels multi-technology radio access; the user equipment establishes a unidirectional channels of different technologies radio access with multiple PDN connections, that is, one part of the PDN connection established by the user equipment via the PDN gateway, receives unidirectional channels of a single technology radio access, while another part of the PDN connection established by the user equipment via the PDN gateway, receives unidirectional channels other technology radio access.

[0100] In this embodiment, the user equipment equipped with the AET unidirectional channels of multiple radio technologies-access to the same PDN connection via the PDN gateway and through the use of a single address PDN, that is, IP addresses. Thus, the waste of resources addresses is prevented. In addition, the user equipment establishes a unidirectional channels of different technologies radio access corresponding to different PDN connections through the PDN gateway and through the use of different IP addresses at the same time, the PDN gateway may know, according to the identifier of the user equipment, unidirectional channels which technology radio access installed user equipment.

[0101] the Aggregation network UMTS and LTE are described below.

[0102] In an aggregated network UMTS/LTE has a homogeneous core network packet. Network LTE system includes such network elements as an object mobility management, serving gateway, PDN gateway, and function policy and charging rules; network system UMTS includes such network elements as the serving GPRS support node, PCRF and the PDN gateway.

[0103] As shown in Fig. 4a, when the SGSN UMTS system supports the interface S3/S4, network radio access UMTS connected with the SGSN via the Iu interface, while the SGSN is connected to the MME and S-GW via the interface S3 and S4 interface. Network radio access UMTS can also be connected directly to the S-GW through the S12 interface; network radio access LTE connected with the MME and S-GW through the interface S1-mme plane control, and interface S1u is elizavetinskoj plane, accordingly, MME and S-GW is connected via the S11 interface plane control. S-GW is connected to the PDN gateway interface S5, while the PDN gateway is connected to the underlying network packet via the SGi interface. Meanwhile, the PDN gateway connected to the PCRF via the Gx interface.

[0104] As shown in Fig. 4b, when the SGSN UMTS system does not support the interface S3/S4, the structure of the aggregated network similar to that of the aggregated network, where the SGSN supports the interface S3/S4, with the following differences: in the aggregated network SGSN is connected to each MME and the PDN gateway via the Gn interface, and network radio access UMTS cannot be connected to the S-GW via the interface S12.

[0105] the Method for communication with the aggregation operation in this embodiment of the present invention may be applied to the aggregated network system shown in Fig. 4a and Fig. 4b. In addition, in this embodiment, the user equipment has the function of transmitting the aggregation LTE/UMTS. Network, the system notifies through the use of a broadcast message to the user equipment on the fact that the network system supports transmission aggregation of LTE/UMTS; the user can allow the transmission function with aggregation LTE/UMTS user equipment using broadcast messages and to access the network with the system. To save energy, the transmission function with aggregation LTE/UMTS user equipment may be prohibited, that is, only the network or LTE network system UMTS is used to transmit data streams.

[0106] In particular, when the SGSN UMTS system supports the interface S3/S4, the following steps are performed.

[0107] (1) Establish a unidirectional channels UMTS and LTE between the user equipment and the base packet.

[0108] As shown in Fig. 5, in one case, the user equipment may first access the LTE radio network and complete the connection to the network (connection to the network)to establish a unidirectional channel LTE PDN gateway. In this process, the network side can assign the IP address of the user equipment. In addition, established a unidirectional channel LTE may include a unidirectional channel (Unidirectional Channel Default) or can include a unidirectional channel and at least one dedicated unidirectional channel. In particular, the set of unidirectional channel LTE includes a unidirectional radio channel (unidirectional radio channel, RB) between the user equipment and the eNB (eNB) of the LTE radio network, a unidirectional channel between S1 eNB and S-GW and a unidirectional channel S5 between S-GW and send the om PDN. Thus, the user equipment may send, through the ascending line of the TFT corresponding to the data streams to a basic network packet through the use of a unidirectional channel LTE.

[0109] If the user equipment allows the aggregation function of LTE/UMTS, when the user equipment detects that the current location covered by the UMTS network, the user equipment may access the UMTS radio network by using the IP address that the network side previously assigns the user equipment. After joining the network, the user equipment establishes a unidirectional channel UMTS gateway PDN. Established unidirectional channel UMTS includes the context of packet data Protocol (PDP Context) between the user equipment and the SGSN or the context of the Protocol packet data or at least one secondary context of the Protocol packet data (Secondary PDP Context). In particular, the set of unidirectional channel UMTS includes a unidirectional radio access channel (RAB) between the user equipment and the UMTS radio network (RAN) and a unidirectional channel Iu between the UMTS radio network and the SGSN. Established unidirectional channel UMTS also includes a unidirectional channel between the SSN and the basic packet or includes a unidirectional channel and at least one dedicated unidirectional channel. In particular, the set of unidirectional channel UMTS also includes a unidirectional channel between S4 SGSN and S-GW and a unidirectional channel S5 between S-GW and the PDN gateway.

[0110] In another case, the user equipment may first access the UMTS radio network. After joining the network, the user equipment establishes a unidirectional channel UMTS gateway PDN using independent signaling establishing a unidirectional channel. If the user equipment allows the aggregation function of LTE/UMTS, when the user equipment detects that the current location covered by the LTE network, it has access to the LTE radio network and establishes a unidirectional channel LTE PDN gateway.

[0111] it Should be noted that the user equipment may establish LTE and unidirectional channels UMTS same PDN connection via the PDN gateway and through the use of the same IP addresses or install LTE and unidirectional channels UMTS different PDN connections through the PDN gateway and through the use of different IP addresses. In addition, after unidirectional channels LTE and UMTS installed, the PDN gateway may store information of the identifier of the user equipment and the identifier information of unidirectional channels LTE and UMTS. Thus, the PDN gateway can the t know what are unidirectional channels installed user equipment.

[0112] (2) Management of UMTS and unidirectional channels LTE quasi-static method for transferring data streams of the user equipment. It is implemented in the following stages, as shown in Fig. 6.

[0113] Step 2-1: the PDN gateway may be obtained by using information from the user's location (the location of the User, ULI)transmitted in the communication relating to the management of unidirectional channel, the location information of the user equipment in radio networks LTE and UMTS. For example, the PDN gateway may receive the location information of the user equipment in the network from ULI transmitted in the request create session Request (Create Session), team resource unidirectional channel (Team Resource Unidirectional channel), the request modification unidirectional channel (Request Modification Unidirectional channel), the response pack unidirectional channel (Reply Unidirectional channel Updates), the reply delete unidirectional channel (Reply Delete Unidirectional channel) or the response delete session Response Delete Session).

[0114] the above-Mentioned ULI can be a global cell ID (CGI), improved global cell ID (ECGI), the ID field is marsrutizatori (RAI) and the identifier of the tracking areas (TAI), where: CGI refers to the ID of the UMTS cell where the user equipment is located; ECGI refers to the ID of the LTE cell where the user equipment is located; RAI refers to the ID field of the routing Area Routing, RA) in the field of packet-switched (PS) of the UMTS system, i.e. the area corresponding to one or multiple geographically adjacent cells. When RA of the user equipment is changed, the user equipment may initiate the procedure of updating routing (RAU), to ensure that the SGSN can know the location of the new area routing, where the user equipment is currently located; TAI refers to the ID field tracking (Tracking, TA) of the user equipment in the LTE system, that is, the area corresponding to one or multiple geographically adjacent cells. When TA of the user equipment is changed, the user equipment initiates the update process tracking (TAU), to ensure that the MME/S-GW can know the location of the new area tracking where the user equipment is currently located.

[0115] it is Clear that the SGSN and S-GW/MME send ULI in the PDN gateway in the process, which is elizavetinskoe equipment attached to the network, and installs, modifies and deletes unidirectional channels LTE and UMTS, including the processes of mobility management, for example the upgrade area tracking (TAU) and update routing user equipment, and the movement of such network nodes as SGSN and S-GW/MME. In UMTS SGSN provides the PDN gateway information CGI and RAI, while in the LTE system, the S-GW/MME provides the PDN gateway information ECGI and TAI. Therefore, the PDN gateway may always know the location information of the user equipment in a UMTS system and the LTE system.

[0116] Step 2-2: the PDN gateway requests, according to the information received, the location of the CGI and ECGI of the user equipment UMTS and LTE, OSS information about network load for UMTS and LTE, where the user equipment is currently located. The OSS records related to such load information as the average number of active users and average traffic within the period of time in each RA or TA.

[0117] Step 2-3: the PDN gateway when the current control mechanism QoS policy can obtain information of the data flow of the application level via the PCRF, and determine, according to the network load information of the data flow of the application-level and a predetermined policy, TFT and technology radio access, which correspond to the unidirectional channel, use isemoa for streaming data to a user equipment, through the use of LTE and UMTS in the areas of uplink communications and downlink, respectively. Thus, the loads in LTE and UMTS systems can be better managed, and the use and throughput of these two systems can be maximized.

[0118] it is Clear that the user equipment and the PDN gateway may know whether the technology is a radio access corresponding to each installed unidirectional channel, LTE or UMTS. When the data streams are defined quasi-static manner, the connection of the TFT and/or PDN can be used to distinguish between unidirectional channels of different technologies radio access. In particular, TFT and technology radio access, which correspond to the unidirectional channel used for transmission of data streams through the use of LTE and UMTS, are determined, and data streams uplink communication or downlink of the same TCP connection are transmitted through the use of a unidirectional channel of the same radio technology access.

[0119] Step 2-4: After determining the way in which data streams are transmitted in the directions of uplink communications and downlink, the PDN gateway configures a unidirectional channel of each radio technology access for user equipment in napravlyaushaya lines of communication and downlink in such a specific way and transmits the data streams of the user equipment configured through the use of unidirectional channels.

[0120] (3) Management of unidirectional channels UMTS and LTE dynamic way to send the data streams of the user equipment. It is implemented in the following stages, as shown in Fig. 7.

[0121] Stage 3-1: the PDN gateway receives the location information of the user equipment in the radio network of the LTE and UMTS using ULI passed in related to the unidirectional control channel message, such as information CGI/ECGI and RAI/TAI.

[0122] Step 3-2: the PDN gateway requests, according to the information received, the location of the user equipment in radio networks UMTS and LTE, OSS information about network load these two networks, where the user equipment is currently located.

[0123] Step 3-3: the PDN gateway determines, according to the network load and a predetermined policy, the way in which the data streams of the user equipment is transmitted through the use of LTE and UMTS in the direction downlink, including the amount of data flows data downlink transmitted through the use of LTE and UMTS, for example certain amount of data or ratio data. Thus, the loads in LTE and UMTS systems can better manage and use and throughput of these two systems can be maximized.

[0124] Step 3-4: the PDN gateway selects, according to Oprah is elenoa the amount of data or ratio data volume data streams, transferred in the direction of the downlink corresponding to LTE or UMTS and transmits the data streams downlink according to a unidirectional channel selected LTE or UMTS.

[0125] it is Clear that, when the way in which transmitted data streams, determined by the dynamic method, the same TFT and/or the PDN connection may correspond to unidirectional channels of different technologies radio access. In particular, different packets of the same data stream can be transmitted through the use of various technologies radio access, and unidirectional channels of different technologies radio access must have the same QoS.

[0126] the Way in which data streams are transmitted in the direction of the ascending line is determined by the user equipment through the use of a return path synchronization. Thus, the user equipment detects the way in which data streams are transmitted through the use of LTE and UMTS in the direction of the downlink, and determines, according to the detected path, the way in which data streams are transmitted through the use of LTE and UMTS in the direction of the ascending line. Finally, the user equipment transmits data streams uplink communication from the corresponding radio network LTE or UMTS core network packet before the Chi so in a certain way, which data streams are transmitted in the direction of the ascending line.

[0127] (4) to Switch between transmission status with aggregation of networks and transmission status in a single network.

[0128] When the user equipment is switched from the state of the transmission network LTE (or UMTS) to the communication state with the aggregation network, the user equipment may initiate an attach procedure to the network (UMTS or LTE). When the PDN gateway receives a join query from the network (UMTS or LTE), it establishes a unidirectional channel (UMTS or LTE) user equipment.

[0129] As shown in Fig. 8, the user equipment may also switch from the current state of the transmission network LTE (or UMTS) to the transmission status with aggregation networks by using the following steps:

[0130] Step 4-1: When the PDN gateway detects that the load of the network (UMTS or LTE), where the user equipment is located, is within a specified range or other cases, the PDN gateway decides to establish a unidirectional channel technology radio access UMTS or LTE) user equipment.

[0131] Step 4-2: the PDN gateway sends a request to create a one-way channel in the S-GW and sends information ID (UMTS or LTE) in the query create a unidirectional channel. In particular, the PDN gateway may add the th information element Type of technology radio access" to request the creation of a unidirectional channel and add information ID (UMTS or LTE) to the newly added information element.

[0097] Step 4-3: S-GW decides, according to the newly included information in the query create a unidirectional channel, a unidirectional channel what technology radio access installed. In this embodiment, the S-GW determines that a unidirectional channel technology radio access UMTS or LTE) is installed with the user equipment.

[0132] Step 4-4: S-GW sends a request to create a one-way channel to the MME or SGSN; MME or SGSN notifies the user equipment of the fact that the user equipment is requested to initiate the accession procedure and the procedure for establishing a unidirectional channel to the radio network (UMTS or LTE).

[0133] When the user equipment is switched from the state of the transmission aggregation networks to the transmission status of the LTE network (or UMTS), the user equipment may initiate the procedure for removing the radio network (UMTS or LTE). When the PDN gateway receives a detach request from the radio network (UMTS or LTE), it removes the unidirectional channel (UMTS or LTE) user equipment.

[0134] when the PDN gateway detects that the load of the radio network (UMTS or LTE) is too large, it sends a request to delete a unidirectional channel that transmits information ID (UMTS or LTE) to the S-GW. In this case, the S-GW, according to the information ID (UMTS or LTE), Uwe who still do user equipment via the MME or SGSN about the fact, that the user equipment is requested to initiate the procedure for removing the radio network (UMTS or LTE).

[0135] the Method for transmission by aggregation of the radio when the SGSN UMTS system does not support the interface S3/S4, similar to the method for transmission by aggregation of the radio when the SGSN UMTS system supports the interface S3/S4, and are not further described.

[0136] the Variant of implementation of the present invention provides a gateway device. The gateway device provided in this embodiment may be a PDN gateway, and a schematic structural diagram of this is shown in Fig. 9. The gateway device includes: unit 10 receiving location, unit 11 receiving the load unit 12 detect and block 13 data.

[0137] the Unit 10 receiving location is configured to receive the location information of the user equipment in at least two radio networks.

[0138] Information location may indicate the current location of the user equipment in the radio network, and information location may be information ID of the current cell of the user equipment, information of the ID field of routing, where the user equipment is located, or information ID tracking where the user about what rudovanie is located, and so on.

[0139] the Unit 11 receiving the load is configured to obtain, according to the location received by the unit 10 receiving the location information, the network load of each radio network, where the user equipment is currently located.

[0140] the Block 12 determining is configured to determine, according to the network load received by the unit 11 receiving the load and a predetermined policy, the way in which the data streams of the user equipment is transmitted using at least two radio technologies-access.

[0141] the predefined policy is the same as described in Embodiment 1, and are not further described.

[0142] it is Clear that the block 12 definitions may consider only the actual load on the network to determine the way in which data streams are transmitted through the use of technology radio access. Thus, after the data streams of the user equipment transmitted through the use of a unidirectional channel of appropriate technology radio access requirements in advance of a given policy can be satisfied, so that load balancing was implemented between each radio network.

[0143] the Block 12 definitions may consider not only the actual load is from the network, but also the information of the data flow of the application layer of the user equipment, that is, other information, such as data transfer on the basis of the requirements of the user equipment, to determine the way in which data streams are transmitted through the use of technology radio access. Thus, after the data streams of the user equipment transmitted through the use of a unidirectional channel of appropriate technology radio access, not only in pre-defined policy, but also the actual requirements of the user equipment can be satisfied. Thus, load balancing between each radio network can be implemented, and the requirements of quality of service of the user equipment can be satisfied.

[0144] the Way in which the data streams of the user equipment is transmitted using at least two radio technologies-access, which is defined by the block 12 definitions may include: what technology radio access and what a unidirectional channel technology radio-access is used to transmit each data stream ascending line and each data stream downlink user equipment.

[0145] Block 13 data proc is guerrette, to send the data streams of the user equipment according to the path defined by the block 12 definitions.

[0146] Block 13 data may be configured in a certain way, which data streams are transmitted through the use of unidirectional channels in each radio technology-access, that is, what technology radio access and what a unidirectional channel technology radio-access is used to transmit each data stream ascending line and/or each data stream downlink user equipment, unidirectional channels each technology radio access in the direction of the ascending line and/or downlink to the user equipment. Thus, in the direction of the downlink, the PDN gateway transmits data streams downlink user equipment configured according unidirectional channel technology radio access in the direction of the descending line; in the direction of the uplink communication of the user equipment transmits data streams uplink communication of the user equipment according to the configured unidirectional channel technology radio access in the direction of the ascending line.

[0147] As is known from the above, in the device the gateway, provided in this embodiment of the present invention, the unit 11 receiving the load receives, according to the location of the user equipment in at least two radio networks, which is received by the unit receiving the location information, the network load of each radio network, where the user equipment is currently located; block 12 defining determines, according to the network load and a predetermined policy, the way in which the data streams of the user equipment is transmitted, through the use of at least two technologies radio access; and, finally, block 13 data transmits the data streams of the user equipment in this certain way. Thus, the amount of data transferred through the use of each technology radio access is dynamically assigned in the aggregated network according to the actual load conditions of the network, so that the resources of each network in an aggregated network were effectively used.

[0148] As shown in Fig. 10, in a particular embodiment, the gateway device may also include block 14 establish multiple unidirectional channels and block 15 delete unidirectional channel.

[0149] Block 14 establish multiple unidirectional channels configuration is associated, to install unidirectional channels of at least two radio technologies-access with the user equipment and to keep the information identifier of the user equipment and the identifier information of unidirectional channels of at least two radio technologies-access.

[0150] the Unit 14 establish multiple unidirectional channels can be set unidirectional channels through the use of any one or multiple of the following ways: the user equipment establishes a single connection PDN unidirectional channels multi-technology radio access gateway, PDN, that is, the user equipment sets through the PDN gateway one PDN connection that takes unidirectional channels multi-technology radio access; the user equipment establishes a unidirectional channels of different technologies radio access with multiple PDN connections, that is, one part of the PDN connection established by the user equipment via the PDN gateway, receives unidirectional channels of a single technology radio access, while another part of the PDN connection established by the user equipment via the PDN gateway, receives unidirectional channels other technology radio access.

[0151] the removal Unit 15 adsonar the certain channel is configured to remove a unidirectional channel any radio network, where the user equipment is located, if the request received disconnect the user equipment in any radio network, or if you determine that the network load any radio network, where the user equipment is located exceeds the specified range.

[0152] the Unit 14 establish multiple unidirectional channels may include block 140 establish a single unidirectional channel, configured to establish a unidirectional channel of the second radio network with a user equipment, if adopted, the join query of the user equipment in the second radio network or if detected that the load network to the second radio network is within a specified range, where the second radio network is a radio network that is different from the first radio network, where the user equipment is currently located.

[0153] In this embodiment, the block 140 establish a single unidirectional channel from the block 14 establish multiple unidirectional channels establishes a unidirectional channel second technology radio access with the user equipment to the user equipment could be switched from a state of transmission over a single network in the state p is passing with aggregation networks; block 15 removal of unidirectional channels removes unidirectional channel any one of the radio network, where the user equipment is located, and switches the user equipment from the transmission condition with aggregation networks in the state of transmission over a single network.

[0154] As shown in Fig. 11, in another embodiment, the unit 12 can determine, in particular, to include the first block 121 definition, the second block 122 definitions and the third block 123 definition, while the block 13 data may include block 132 select the radio unit 133 radio routing.

[0155] the First block 121 determining is configured to determine the pattern of traffic flow TFT and technology radio access, which correspond to the unidirectional channel used to transmit data flow of the user equipment in the direction of the ascending line and/or the direction of the descending line.

[0156] the Second block 122 determining is configured to determine, according to the network load information of the data flow service level of the user equipment and a predetermined policy, the pattern of traffic flow TFT and technology radio access, which correspond to the unidirectional channel used to transmit data flow of the user equipment in the managing uplink communication and/or direction of the descending line.

[0157] In this embodiment, the first block 121 definition and the second block 122 to determine control data streams quasi-static manner, and a unidirectional channel one and the same technology radio access must be used to transmit the same data stream, i.e. the stream data uplink communication or downlink of the same TCP connection. This prevents the loss of TCP performance caused by large differences between the delays of the transmission, when the same data stream is transmitted through the use of various technologies radio access. Each data stream corresponds to the TFT.

[0158] After the first block 121 definition and the second block 122 definition in the gateway device to determine when the quasi-static method of distribution the way in which transmitted data streams uplink communication and/or downlink, block 13 data configures a unidirectional channels in each radio technology access in the areas of uplink communications and downlink according to the path defined by the unit 12, and transmits the data streams in the areas of uplink communications and downlink according to the configured unidirectional channels.

[0159] the Third block 123 determining is configured to determine the amount of d is the R or the proportion of the amount of data data flow of the user equipment, which are transmitted through the use of at least two radio technologies-access in the direction of the descending line.

[0160] the Block 132 select the radio is configured to select, according to the data amount or proportion of the amount of data defined by the third block 123 definition of block 12 definition, technology radio access, which is used for streaming data to a user equipment in the direction of the descending line.

[0161] the Block 133 radio-routing is configured to transmit data streams of the user equipment in the direction of the downlink by using a unidirectional channel technology radio access selected by the block 132 selecting the radio.

[0162] In this embodiment, the gateway device manages data flow dynamic way. The third block 123 definition of block 12 definition specifies dynamic data volume or the ratio of the volume of data streams transmitted by using each technology radio access in the direction of the descending line; block 132 select the radio selects, according to the data amount or proportion of the amount of data defined by the third block 123 definition, technology radio access, which is used for streaming data downlink, and the block 133 RA is IO-routing transmitting data downlink through the use of selected technology radio access.

[0163] As a unidirectional channels of different technologies radio dynamic access method can use the same TFT, the following can be configured: the same TFT corresponds to unidirectional channels multiple different technologies radio access so that unidirectional channels to transmit data flows with the same QoS requirements. This prevents the loss of TCP performance caused by large differences between the delays of the transmission, when a unidirectional channels of different technologies radio-access is used to transmit the same data stream, i.e. the stream data uplink communication or downlink of the same TCP connection.

[0164] the Variant of implementation of the present invention provides a user equipment. As shown in Fig. 12, the user equipment includes: a detection block 20 downlink, block 21 definition information uplink communication and the block 22 data access.

[0165] the detection Block 20 downlink is configured to detect the way in which the data streams of the user equipment is transmitted using at least two radio technologies-access in the direction of the downlink, where the way in which streams of data which the user equipment is transmitted using at least two radio technologies-access in the direction of the downlink, defined by the gateway packet data network (PDN) according to the network load at least two radio networks, where the user equipment is currently located.

[0166] the Unit 21 definition information of the upward communication line is configured to determine, according to the path detected by the detection block 20 downlink, the way in which the data streams of the user equipment is transmitted using at least two radio technologies-access in the direction of the ascending line.

[0167] When the block 21 definition information uplink communication determines the way in which data streams are transmitted in the direction of the ascending line, he may determine, according to the proportion of the amount of data transfer through the use of at least two radio technologies-access in the direction of the downlink or according to predefined relationship calculation, the way in which the data streams of the user equipment is transmitted in the direction of the ascending line. For example, the proportion of the amount of data transfer through the use of at least two radio technologies-access in the direction of the descending line is used as the ratio of the amount of data transfer through the use of at least DV is x technology radio access in the direction of the upward communication line; or proportion of the amount of data transfer through the use of at least two radio technologies-access in the direction of the upward communication line, an equal proportion of the amount of data transfer through the use of technology radio access in the direction of the descending line, multiplied by a scaling factor, where the scaling factor can be configured in the user equipment or dynamically configured by the party network through signaling.

[0168] the Block 22 data access is configured to transmit data streams uplink communication of the user equipment from the corresponding radio network to the core network packet according to the path defined by the block 21 definition information of the ascending line.

[0169] As is known from the above, in the user equipment provided in this embodiment, the block 21 definition information uplink communication determines, according to the way in which data streams are transmitted by using at least two radio technologies-access in the direction of the downlink detected by the detection block 20 of the descending line, the way in which data streams are transmitted to a user equipment used by the I of at least two radio technologies-access in the direction of the upward communication line, and the block 22 access to the data transmits the data streams from the respective radio network to the core network packet. Since the information data flow of the user equipment in the direction of the downlink is determined dynamically according to the actual load conditions of the network, the resources of each network in an aggregated network effectively used.

[0170] In a particular embodiment, the user equipment also includes a block 23 establishing a unidirectional channel, configured to establish a unidirectional channels of at least two radio technologies-access through the PDN gateway.

[0171] When the block 23 establishing a unidirectional unidirectional channel sets the channel with a PDN gateway, it may use any one or more of the following ways: One PDN connection that the block 23 establishing a unidirectional channel sets through the PDN gateway, receives unidirectional channels multi-technology radio access; block 23 establishing a unidirectional channel sets unidirectional channels of different technologies radio access with multiple PDN, that is one part of the PDN connections that the block 23 establishing a unidirectional channel sets through the PDN gateway, receives unidirectional channels of a single technology radio on the stupa, while another part of the PDN connections that the block 23 establishing a unidirectional channel sets through the PDN gateway, receives unidirectional channels other technology radio access.

[0172] In this embodiment, the block 23 establishing a unidirectional channel sets unidirectional channels of multiple radio technologies-access to the same PDN connection via the PDN gateway and through the use of a single address PDN, that is an IP address. Thus, the waste of resources addresses is prevented. In addition, the block 23 establishing a unidirectional channel sets unidirectional channels of different technologies radio access corresponding to the different PDN connections through the PDN gateway and through the use of different IP addresses, while the PDN gateway may know, according to the identifier of the user equipment, unidirectional channels which technology radio access installed user equipment.

[0174] the PDN gateway Device is configured to determine, according to the network load at least two radio networks, where the user equipment is currently located, the way in which the data streams of the user equipment is transmitted using at least two radio technologies-access in the direction of the descending line.

[0175] All blocks in the user equipment and a gateway device provided in this embodiment of the present invention can perform transmission and aggregation networks according to the methods provided in the Embodiment 1 and the Embodiment 2, and details are not described here.

[0176] In conclusion, through use of the method, system and device for aggregation of radio networks in the variants of implementation of the present invention, the PDN gateway obtains, according to location of the user equipment in at least two radio networks, information network load of each radio network, where the user equipment is currently located, and determines, according to the network load and a predetermined policy, the way in which the data streams of the user equipment is transmitted through the use of at least two technologies, radio access, and the finally, transmits the data streams of the user equipment in this certain way.
