BACKGROUND of INVENTION

The technical field to which the invention relates.

[0001] the Invention relates to the control node of the network, terminal and method of controlling various types of communication sessions.

The level of technology

[0002] the Invention relates to the field of multiple access and mobility. Currently, the project third generation partnership (3GPP) discusses the various ways of implementing mobility access of mobile users (Mobile Access, MA).

[0003] currently, there are several problems associated with the use of mobile solutions:

[0004] For each mobile solutions has its own gateway. Typically, the traffic must pass through many gateways (for example, a gateway GPRS support node (GGSN) and a private agent (Home Agent)).

[0005] For each mobile solutions using a certain type of tunneling. The use of many types of tunneling is not optimal, especially when using a cellular access.

[0006] For each mobile solutions has its own mechanism for selection of the gateway. Usually it is difficult to make a choice is identical to the gateway.

[0007] in Addition, Protocol for Mobile IPv4 need a way to configure the clients.

[0008] Therefore, it is necessary to improve the handling of communication sessions in the network.

A SUMMARY IMAGE IS ETENIA

[0009] Therefore, the purpose of this invention is to solve the aforementioned problems and provide mobility and integrity of the session, even if through a gateway feature other solutions for mobility.

[00010] In accordance with some implementations of the present invention this objective is achieved by a gateway, comprising: a supporting unit configured to support multiple types of communication sessions, providing unit configured to provide a communication session with the terminal, and associating unit configured to associate the parameter with the communication session with the terminal.

[00011] alternatively, in accordance with some implementations of the invention this goal is achieved by a terminal, comprising: a supporting unit configured to support multiple types of communication sessions, providing unit configured to provide a communication session with the gateway, and a receiver configured to receive parameter associated with the gateway.

[00012] as another alternative, in accordance with some implementations of the invention this goal is achieved through a method of controlling the gateway on the network that provides the gateway can support multiple types of communication sessions. This method includes providing a communication session with the term the cash and associating a parameter with the communication session with the terminal.

[00013] in Addition, in accordance with some implementations of the invention this objective is achieved by way of a control terminal, which provides the ability to support multiple types of communication sessions. This method includes providing a communication session with the gateway and receive a parameter that is associated with the gateway.

[0010] In accordance with a typical implementation of the invention provides for the use of the system to ensure mobility to the terminal through at least two different protocols mobility, in which:

[0011]gateway mobility and terminal share a common session mobile

[0012] the above - total mobile communication session can be updated through the use of any of the various protocols, mobility, and

[0013] each Protocol mobility during registration provides information for terminal related to all other protocols mobility.

[0014] Thus, even when the terminal changes the type of connection to a network control element (e.g., a wireless LAN (WLAN) switches on the General packet radio service destination (GPRS)), the communication session, as such, can be correctly identified. Therefore, the mobility and integrity of the session can be ensured even in the case if provided different solutions for mobility (different types of communication sessions).

[0015] That is, the invention provides a solution to mobility, which can be combined in numerous technologies mobility and the opportunity to support the integrity of the sessions within these various technologies mobility.

A DETAILED DESCRIPTION of the PREFERRED EMBODIMENTS

[0025] the Following describes preferred embodiments of the present invention with references to the accompanying drawings.

[0026] In General, the preferred embodiments involve the use of integrated mobile solutions, where a single gateway (defined also as a gateway mobility or integrated gateway mobility) supports one mobile communication session using multiple t is hnology mobility, and this gateway has the ability to return to the configuration settings of the mobile node (Mobile Node, MN) or session parameter to ensure that the node MN will remain connected to this previous gateway, if technology is used mobility. In particular, the gateway assigns the same private address of the node MN when session changes technology mobility, so that the change of technology mobility remained invisible on the corresponding node.

[0027] in Addition, the terminal (i.e. mobile node, MN)performing one mobile communication session is to update this session mobile communication through the use of different protocols (mechanism 3GPP; protocols Mobile IP and Mobike) depending on their access. In addition, after the connection with the use of one Protocol node MN will receive the configuration settings/session and use them to configure another part of the protocols of the mobile communication session.

[0028] the Following is a more detailed example corresponding to the first embodiment of the invention, with reference to the signalling flow shown in figure 1.

[0029] In this example, assume that the above gateway is an intelligent service node (Intelligent Service Node (ISN)) (integrating modules GGSN-MPv4 Home Agent), and mobile station (Mobile Station, MS) produces a first connection via GPRS.

[0030] the Following describes the signalling flow. It begins with the power GPRS, provided the combination of a support node gateway GPRS (GGSN) and a private agent.

[0031] In step A1, the user object (User Entity, UE), mobile station (Mobile Station, MS) or a mobile node (Mobile Node (MN) sends a context request Protocol packet data (Packet Data Protocol, PDP). It is desirable that the station MS added indication that indicates support for integrated mobility MIPv4. It is preferable to add the display to the option configuration Protocol Configuration Option), so that the support node service GPRS (Serving GPRS Support Node, SGSN) made transparent to the transmission of these data. In Fig. 1 display contains the identifier (ID) of the mobile communication session. A certain value, for example "0000"indicates the absence of prior mobile communication session.

[0032] After that, the site ISN't created an integrated mobile communication session (step A2). It is possible to correct this integrated mobile communication session via GPRS or MIP, as shown below. This integrated mobile communication session is completed, if deactivates the GPRS communication session. This will be a possible update using Mobile IP Protocol

[0033] In step A3, the site ISN returns an acknowledgement to the PDP context that contains the IP address of the own agent (Home Agent) MIPv4 Protocol (and/or additionally, for example, the identifier of the access network by its home address (Home Address Network Access Identifier, HA NAI), in accordance with the document RFC3846), temporary shared secret data (valid for this session), the index of the parameter Security Parameter Index SPI) and, optionally, the identifier of the GGSN (preferably encoded in the form of a name of the access point (Access Point Name, APN)). Optional, may be included unique identifier of the mobile communication session. It is preferable to add these data to the configuration options Protocol Configuration Option), so that the node SGSN made them transparent transmission. Pay attention to the fact that the IP address returned station MS in response to the activate PDP context will be the address of the node MN for mobile communication session. Thus, this address is a private address for the Mobile IP Protocol.

[0034] that is, up until station MS remains in the GPRS network, it sees itself as being in its core network (from the point of view of the Mobile IP Protocol and does not use Mobile IP Protocol. The site ISN station and the MS supports the mobile communication session that contains the GPRS settings and temporary shared secret data (actually the s for this session), the parameter index security SPI. There is no active communication session Protocol MIP, but the station MS has configured his stack Mobile IP using parameters obtained from the activation of the PDP context (ON the address; home address; shared-secret data; index SPI).

[0035] In step A4 now assume that node MN detects a wireless local area network WLAN, which has a higher priority than the cellular network, for example, its own core network Note WLAN.

[0036] Thus, in step A5, this node sends a registration request MIP Registration Request (RRQ) TO the address obtained in step A3. Field authentication is calculated using the temporary shared secret data and index SPI obtained in step A3. Request RRQ includes a private address assigned in step A3 gateway GGSN. It is also desirable that the request included the identifier NAI (in accordance with RFC 3846) and the session ID of the mobile communication as vendor extensions.

[0037] In step A6, the site ISN receives the request and finds the proper context of the communication session, using the session ID of the connection (Pay attention to the fact that it is supposed to support the combined address as its own address is not enough to uniquely identify the station MS). The site ISN authenticates station MS and podtverjdaet request. That is, in step A6, the mobile communication session identified by session ID, mobile communication, are the security procedures for verification of your request, and you are upgrading the site ISN't to route the session through this new treatment.

[0038] In step A7, the corresponding response (R Resp) is sent to station MS. Optional, the same session ID of the mobile communication should be included (to simplify the Protocol) in the confirmation message, and must include the identifier of the GGSN, encoded in the form of a name of the APN. A communications session is established using the MIP Protocol. For example, the tunnel type "1P to 1P" and now all traffic is routed to a safe station address MS.

[0039] the Node ISN station and the MS supports the mobile communication session (identified by the unique session ID for mobile communication), containing the parameters of the tunneling Protocol GTP (GPRS Tunneling Protocol) and the Protocol parameters of the MIP. Both sessions are active.

[0040] subsequently, the node SGSN can deactivate the PDP context based on the timer (no traffic data in the SGSN). Thus, in step A8, the PDP context is deactivated. Node ISN't removed parameters related to the GTP tunnel.

[0041] the Node ISN station and the MS supports the mobile communication session (defined by unique is determined as being the session ID of the mobile communication), contains the parameters of the MIP Protocol. Station MS also contains the identifier of the GGSN, encoded in the form of a name of the APN. The GTP session is not activated.

[0042] In step A9, it is assumed that the station MS is returned again to the coverage area of cellular communication. Because it has an active mobile communication session, it will not use its access point APN by default, and the access point name, which was obtained in step A3 or A7 (GGSN ID). The standard node SGSN will send the request to the same site ISN't (because only the node associated with this access point name APN). Station MS adds the session ID of the mobile communication. It is preferable to add these data to the configuration options Protocol Configuration Option), so that the node SGSN made transparent transfer of this identifier.

[0043] In step a10, the site ISN returns an acknowledgement to the PDP context that contains the IP address of the own agent ON the MIPv4 Protocol (and, optionally, the logical name FOR NAI, in accordance with the document RFC3846), temporary shared secret data (perhaps this new data is valid for this session), the parameter index security SPI and the identifier of the GGSN (preferably encoded in the name of the APN). Optional, may be included the same session ID for mobile communications (to simplify about the next). It is preferable to add these data to the configuration options Protocol Configuration Option), so that the node SGSN made them transparent transmission.

[0044] the Following is another example of using links to the signalling flow shown in Fig. 2A. This example assumes the use of intelligent service node (Intelligent Service Node (ISN)) (integrating modules GGSN-MIPv4 Home Agent) and it is assumed that station MS produces a first connection using the Mobile IP Protocol (MIP).

[0045] There is shown below the flow alarm, which reflects, in particular, activating the WLAN, and then move to the GPRS network, providing a combination of gateway GGSN and a private agent.

[0046] In step B1 node MN is connected, e.g. via WLAN, by querying the MIP Registration Request on a pre-configured TO address. Field authentication is calculated using a pre-configured shared secret data and index SPI. Request RRQ includes the ID of the MN NAI in order to request the appointment of a dynamic of its own address. It is also desirable that the request included a session ID for mobile communications, is set to "0000" as vendor extensions.

[0047] In step B2, the site ISN receives the request, authenticates the node MN finds it is a new session (as in step B1, the session ID is equal to "0000"), and then dynamically assigns a private address and a unique session ID. The site ISN returns the confirmation message, the identifier of the GGSN, encoded in the form of a name of the APN. A communications session is established using the MIP Protocol. For example, the tunnel type "IP in IP" and now all traffic is routed to a safe station address MS.

[0048] In step B3 node MN updates on this session mobile its configuration GPRS using the obtained name of the APN. This is illustrated also in Fig. 2B, which shows the corresponding structure of the levels. Levels of MIP, IP and WLAN in bold to highlight settings.

[0049] a Layered structure identical to the terminal and the gateway.

[0050] in Addition, the terminal may be a separate device (e.g. mobile phone) or may consist of many different devices.

[0051] for Example, the overall level of mobility may be a portable computer, and the level of GPRS can be placed on the map data.

[0052] On the rate structure is evident that you have the top overall level of mobility.

[0053] In the terminal this General level of mobility provides:

- virtual interface from the application

- a single private address, General d the MIP I and GPRS

- ability to switch between GPRS and MIP without impact to the application

- when you start a session or when performing updates, the overall level of mobility will be able to configure one stack (e.g., GPRS) using data (GPRS APN; common session ID), obtained through another stack (e.g., MIP).

[0054] the Following describes a tiered structure for the gateway, which is similar to those shown in figv.

[0055] Typically, the gateway combines multiple technologies mobility.

[0056] In the gateway of the General level of mobility provides:

- manage the registration procedure

- creates the information you submit during the registration process on station MS (for example, my address...)

- creates a unique session ID

- supports the communication session when changing the Protocol mobility

- hides the fact that switching between GPRS and MIP for any external linked sites

- when the session starts and when performing updates, the overall level of mobility will provide the same stack (e.g., GPRS) with the information that you want to send to the terminal (MIP address, security settings, names; common session ID)for a different stack (e.g., MIP).

[0057] In step B4 now assume that node MN loses who is very useful for interaction with WLAN, since this time he switched to packet-GPRS radio network.

[0058] Thus, in step B5 node MN sends a request create PDP that includes the session ID of the mobile communication received in step B2, and uses the name of the APN received in step B2. Node SGSN typically selects the GGSN (for example, using a domain name server Domain Name Server (DNS)). The network is configured in such a manner that the APN name clearly indicated the node ISN't selected in step B1. It is preferable to add the session ID of the mobile communication option configuration Protocol Configuration Option), so that the node SGSN made transparent transmission of this parameter.

[0059] In step B6, the site ISN returns an acknowledgement to the PDP context that contains the IP address of the own agent ON the MIPv4 Protocol (and, optionally, the logical name FOR NAI, in accordance with the document RFC3846), temporary shared secret data and the parameter index security SPI. Optional, may be included the same session ID for mobile communications (to simplify the Protocol). It is preferable to add these data to the configuration options Protocol Configuration Option)to the node SGSN made them transparent transmission.

[0060] Steps B7 and B8 in the diagram shows what happens when a station MS switches back to the connection with the use of PR is the MIP Protocol.

[0061] In particular, in step B7 node MN sends to the node ISN request MIP RRQ, containing the session ID for mobile communications (which in this case may, for example, have a value of "1111"). In step B8, the site ISN sends to node MN response R Resp, incorporating a vendor extension that specifies ISN (i.e., APN="GGSN/HA7"), the address of the own agent Address of the Home Agent, HoA) and the session ID of the mobile communication.

[0062] the Following is a description of the implementation of the mobile node (MN). The preferred way to implement station MS is using a combined level of mobility between the application and stacks GPRS and MIP. The application will use a virtual interface for communication with this combined level of mobility and will be available through this interface is its own address. The combined level of mobility will be stored in the context information associated with the mobile communication session, to monitor active interface (MIP or GPRS) and to configure the MIP protocols and GPRS using the appropriate parameters for the active mobile communication session. When the mobile communication session is completed, the combined level of mobility can destroy the parameters related to the mobile communication session. Then the next time the communication stack GPRS and MIP will use the pre-configured the settings.

[0063] In accordance with the first embodiment of the invention, the session ID of the mobile communication is used as a parameter to identify a communication session (such as a mobile communication session). That is, it is assumed that one node MN can have multiple sessions. Identifier Mobility Session ID is a reliable way to uniquely identify the appropriate session. To uniquely identify a session can not be used IP address, because of the overlapping of private addresses.

[0064] the ID of the node MN can be used to uniquely identify the session, but this will reduce to one session limit for MN on the number of sessions. This is inconvenient, because different protocols mobility typically use different types of identifiers. It will not allow support of this concept, as the router is a universal system for mobile communications (Universal Mobile Telecommunications System, UMTS) (multiple computers connected to the same modem UMTS).

[0065] As mentioned above, the session ID for mobile communications (which is also abbreviated is defined as a session ID) can be used if supported and can be integrated mobility. This can be specified in step A1 by using the session ID is, equal to "000000".

[0066] Analysis of security issues. The proposed mechanism provides sufficient security, as temporary shared secret data encrypted for the radio, return via GPRS. To increase security, the shared secret data may be returned in encrypted form. There are many other opportunities to improve security, but it is not the main issue.

[0067] Backward compatibility. Older versions of the gateway GGSN or your own agent will simply ignore the new field. Station MS must be able to communicate with these devices and creating a separate GPRS session and MIP.

[0068] If the first connection is made using the MIP Protocol, it is necessary to station MS had preconfigured secret data shared and private agent MIP. However, the alternative is an option when station MS is always first connect to the GPRS network. Another alternative is to store a station MS and the network settings of the previous session.

[0069] the Following describes the second embodiment of the invention using the links in figure 3 and 4.

[0070] In accordance with the above-described first embodiment of the alarm GPRS VK is uchet parameters MIP, and alarm MIP includes the GPRS settings. That is, for example, the session identifier of the mobile communication is included in the confirmation message of the PDP context (step A3).

[0071] However, in accordance with the second embodiment of the alarm initiates the GPRS Protocol message MIP (Agent Advirtisements (Advertising agent)), in which parameters are passed MIP (including the session ID of the mobile communication), instead of sending these settings in the GPRS alarm.

[0072] figure 3 shows the corresponding modification of the signalling flow shown in figure 1. Here are the steps C1-C10 identical to steps A1-a10, except steps C3 and C10 and adding steps C3bis and C10bis.

[0073] In steps C3 and C10 is only sent message confirmation PDP context without specifying other parameters. Instead, on the steps C3bis and C10bis message is sent to the Agent Advertisement agent)that includes these options.

[0074] figure 4 shows the corresponding modification of the signalling flow shown in figure 2. Here are the steps D1-D8 are identical to the steps B1-B8, with the exception of step D6 and add step D6bis.

[0075] Similarly to the procedure shown in figure 3, in step D6 is only sent message confirmation PDP context without specifying other parameters. Instead, in step B6bis message is sent to the Agent Advertisement agent)that includes these options.

[0076] Below is described the e of the third embodiment of the invention, which has a parameter for identification.

[0077] In accordance with this embodiment to identify the site ISN parameter is used TO NAI. This is shown in figure 5 and 6.

[0078] the Use of AT NAI especially useful if you have a group of their own agents ON the same IP address. That is, the parameter ON the NAI will uniquely identify one's own agent. In the case of using the site ISN't the type Flexi this will uniquely identify appropriate service map. It should be noted that the Protocol can be designed to NAI=GGSN APN, providing an unambiguous identification for the node ISN't.

[0079] In a preferred implementation of the invention in accordance with the present embodiment with the node ISN binds one logical name. This name can be used as an identifier FOR NAI (RFC3846), or the name of the access point (Access Point Name, APN) gateway GPRS. The advantage is that can be used for standard signaling Protocol MIP (no new extension provider to send back the name of the APN - ID is sent only ON NAI). Then the client will use the returned logical name as the name of the APN for GPRS alarm.

[0080] This is illustrated in figure 5 and 6, in which steps E1-E10 and F1-F8 are identical to steps A1-a10 and B1-B8 on the Phi is .1 and 2, accordingly, with the exception of steps E7, e, F2, F5 and F8.

[0081] figure 5 in step E7 in the message R Resp is sent to the identifier NAI instead of the identifier of the GGSN. It is used to request PDP context in step e.

[0082] figure 6 in steps F2, F5 and F8 message R Resp contains the identifier NAI instead of vendor extensions used in steps B2, B5, and B8 in figure 2.

[0083] Thus, through the above-described implementations of the invention can always be reliably identified communication session. The implementation does not lead to the absence of call signaling Protocol GPRS, it provides a simplified configuration, and traffic will only pass through a single gateway instead of two gateways. In addition, the 3GPP operators now have the ability to maintain control of the subscriber.

[0084] Figa illustrates the basic configuration of the gateway in accordance with these accomplishments. In particular, the gateway 1 may contain supporting unit 11 configured to support multiple types of communication sessions, providing unit 12, configured to provide a communication session with the terminal, and associating unit 13, configured to associate the parameter with the communication session with the terminal.

[0085] FIGU illustrates the basic configuration of the terminal in accordance with these accomplishments. The terminal 2 may include maintaining the first block 21, configured to support multiple types of communication sessions, providing unit 22, configured to provide a communication session with the gateway and the receiver 23, configured to receive a parameter that is associated with the gateway.

[0086] the Invention is not limited to the above-described embodiment is different versions.

[0087] for Example, the invention is not limited to protocols mobility, which is described above, but it is also applicable to other protocols for mobile communication. Using the principles described here, the joint session provider may support communication for more than two basic protocols.

[0088] a Particularly suitable example is the Association of mobility 3GPP LTE (Long Term Evolution), GPRS and Mobike. In this case, connect using IPsec through Mobike; expansion in Mobike will provide node MN by using the node ID ISN (alternatively can be used 2 ID - one for LTE and one for GPRS) and the unique ID of the mobile communication session. When the station MS moves in a 3GPP LTE network, it will send the ID of the node ISN't connected to the same gateway, and that gateway is uniquely identified by a session by session ID of mobile communication. As modest the military IP address will be assigned to station MS, external matching node will not detect any changes.

[0089] Similarly, the invention is applicable also to the MIPv6 Protocol. One difference is a slight difference in the security settings of the MIPv6 Protocol. Another difference in MIPv6 is that my address IPv6 is unique, and in some cases, you can not use session ID.
