The technical field TO WHICH the INVENTION RELATES

The present invention relates to the field of technology associated with the transfer of the session in the communications network.

The LEVEL of TECHNOLOGY

Standard Long-term Development (LTE) is a technology and communication network, which is currently being developed by the Partnership Project 3rd Generation (3GPP). The LTE project requires the use of the new radio access method, referred to as a Developed Universal Terrestrial Radio access Network (E-UTRAN), which is designed to increase network capacity, reduce delays in the network and therefore improve the readability for the end user. The System Architecture evolution (SAE) is the basic network architecture for communication networks of the LTE standard.

The LTE standard uses only the alarm packet-switched (PS). When a network operator wishes to enter the LTE standard, it will not have the opportunity from day one to fully launch the service of the LTE standard. Requires gradual implementation of the LTE standard to replace existing technologies. To do this, the LTE network must have a certain way of interacting with networks that use a different technology, such as alarm circuit-switched (CS). Technology separate continuity of a Voice Call on the Radio interface (SRVCC) described in 3GPP TS 23.237 and 3GPP TS 23.216,�possible to ensure the transfer of the session from the LTE network to the CS network.

Fig. 1 illustrates a scenario in which the User Equipment (UE) 1 is mounted bearer of the LTE standard with the ongoing chat session using the Transfer Subsystem Multimedia, IP-based (IMS) at location 2 with a coverage area of the LTE standard. Then UE 1 moves to the second location 3, in which the coverage area of the LTE standard is no longer available, however, the coating provides the traditional CS network. LTE network communicates with the Server 4 of the Switching Center Mobile Communications (MCS) to indicate that it is necessary to transfer the session from the LTE network to the CS network. Server 4 MCS notifies the network 5 IMS on transfer of service. Then the IMS network makes sure that the session may be processed by the CS network.

Similarly, the referral service may occur from UTRAN (HSPA) using IMS to the CS access. In the description below, we use the example of LTE, however, it can be replaced with standard HSPA.

The problem occurs when, for example, you want to transfer a video call from the LTE network to the PS network. Access network does not know about what a challenge that must be moved from PS access to CS is a video call, and, thus, the access network cannot determine the difference between load bearing channels used in the creation call, to transfer video from a video call, or not�painful on TV used for other video applications such as video sharing app or a Mobile TV session.

One proposal (described in 3GPP TR 23.886v0.3.1) in relation to procedures for SRVCC call assumes that the access network may determine that a video call, by contacting to the supporting channels that have been set. Each carrier channel is assigned to the Class Identifier quality of Service (QCI) depending on the type of audio-visual information, which is transported bearer. If there is one bearer with QCI=1 (indicating the voice) and another bearer with QCI=2 (indicating the video), then it is assumed that the call is a video call, and the session should be moved accordingly.

The problem with this solution is that it limits the use of the existing support channels. Although QCI=2, usually used for the video component of the video call, however, QCI=2 can be used for other types of videos, thus, the requirement to QCI=2 was used only for video calls, creates problems of backward compatibility with existing terminals and applications that can use QCI=2 for videopremiere than video calls. In addition, as described in TR 23.886v0.3.1 assumes that only one bearer can use QCI=2. �due to the fact that, that streaming video can be done using a variety of applications, each of which uses QCI=2, and there is no way to know from QCI=2, any bearer refers to a video call.

An additional problem is that operators may be desirable to use QCI, than 2, for video calls. For example, a network operator may wish to reserve QCI=2 for mobile TV in the network. It would be impossible if the solution is described in TR 23.886v0.3.1, since when it detects a video call would be a mistake to assume that videomobile TV refers to the call.

It should be noted that this problem is not related specifically to the video, and refers to any type of session, wherein the session requires more than one bearer.

The IMPLEMENTATION of the INVENTION

The invention avoids the problems associated with the fact that the QCI values trust to identify the type of service, by providing the indicator of the type of service that can be used to transfer access transfer of a session. The following description uses an example in which the service type is a video call, although it should be borne in mind that the invention can be applied to other types of services, such as sending of Fax messages or CS data.

According To Fig. 2, when the UE 1 establishes a session (step S1) using the network of the LTE standard, the node 6 Functions Session Management Calls to the Proxy server (P-CSCF) in the IMS network determines the type of service. It should also be noted that step S1 can be performed in the case where the service type is changed during the session. Example�, exactly the same procedures apply when a voice call is being upgraded to a video call.

In step S2, the node P-CSCF communicates with the node 7 Function Policy and Charging (PCRF), to make sure that the session is created access resources. This includes the establishment of suitable load-bearing channels to be sent during a session of audio-visual information. Node 6 P-CSCF may also indicate to the PCRF node 7 used the service, for example, by sending the Identifier IMS Communication Services (ICSI). As an extension, the node P-CSCF can also specify what type of service used, e.g. voice call or a video call. This gives the PCRF node 7 more information to enable him to determine how to handle the session without requiring the PCRF understanding of what ICSI is matched with any type of service. It should be noted that can be accessed more than one service that can be used to establish a video call, and any of these services must be performed with the possibility of transfer in the case that the session moves from the access network in PS CS.

In step S3, the node 7 PCRF initiates the creation of the respective bearers for the session (e.g., QCI=1 bearer for the voice portion of the call, and QCI=x bearer for the video portion of the video call), through interaction with the PDN Gateway (PGW) or Service �Luz and is easily accessible by 8 (SGW). The PCRF node 7 also indicates to the PGW/SGW 8 that the session belongs to the call, by sending to the PGW/SGW 8 indicator service type indicating the type of service, e.g., service type = video-call". An example of the types of services that may be specified include voice call, video call, CS data, the call priority IMS or Fax message.

It should be noted that in the case where a PCRF node 7 receives from node 6 P-CSCF only used the service connection, the PCRF node 7 will need to use a local policy to map communication service with the service type, and to determine the appropriate indicator service type.

In step S4 PGW/SGW 8 interacts with the Object 9 Mobility Management (MME) during the allocation of the bearer channel, since the MME is involved in the activation/deactivation of carrier channels. MME is also responsible for choosing the SGW 8 and UE authentication and user through interaction with the Home subscriber Server (HSS) in the IMS network. PGW/SGW 8 sends an indicator of the type of service MME 9. As a result, and with regard to the video call, the MME 9 examines the bearer that belongs to a QCI=QCI 1 and=x, as pertaining to the indicator type of service. In other words, if the indicator type of service indicates that the session is a video call, the MME 9 connects the QCI=1 and QCI=x with the call.

If during the session it is not necessary to transfer seasonid access networks, the indicator type of service will not be used. However, if there is a need to transfer the session from the network of the LTE standard in the CS access network, SRVCC procedures are initiated, as illustrated in Fig. 3.

In step S5 eNodeB 10 points for MME 9 that the session should be transferred to the CS network, and that requires SRVCC procedure.

In step S6 MME 9 indicator knows the type of service for the session, subject to transfer of access (for example, the fact that it is a video call), and bearing channels associated with the type indicator services. Consequently, the MME handles 9 QCI=x bearer (for the video portion of the video call) similar to how it handles QCI=1 bearer in respect of the transfer of PS access and in cases of suspend/resume during the SRVCC procedures as described in 3GPP TS 23.216 v9.4.0. Thus, the session is identified as pertaining to the call, however there is no need to use QCI=2, as suggested in TS 23.886 v.0.3.1, to specify the video portion of the call that provides the operator with greater flexibility in the appointment of QCI values for videoseasy channels.

In an optional embodiment, the implementation, MME 9 may decide not to perform SRVCC procedures of a particular type of service, but instead to perform only normal SRVCC procedure. In this case, the MME 9 still can handle QCI=x bearer similarly QCI=1 are�him channel. This may occur, for example, if the network operator does not wish to support SRVCC procedures of a particular type of service for this subscriber.

If the configuration is performed, in order to do this, the MME 9 indicates the service type, the MSC Server 4 during the transfer. This can be accomplished simply by redirecting indicator type services MSC Server 4. This allows the MSC Server 4 to allocate resources for video calls or to use procedures that are specific for video calls. The MSC server 4 performs the request and confirms the MME 9, have successfully performed the procedures SRVCC certain type of service or were only made normal SRVCC procedure. Normal SRVCC procedure can be performed, for example, if the access is used after the transfer, does not support the video call, for example, in the case of a GERAN network.

In an additional embodiment of the invention, as illustrated in step S7, the network (in other words, the Server 4 MSC and MME 9) indicates the UE 1 that performs procedures SRVCC for a particular type of service, and indicates the bearing channels associated with the session. In a situation in which the network may not be able to reliably fulfill videoproiettori SRVCC, informing the UE 1 on the procedures SRVCC ensures that UE 1 will not attempt to perform all videoproiettori SRVCC in the case where this will not allow the network. Such cases included in �you, for example, a local politician or a temporary lack of resources.

Fig. 4 illustrates the MME 9. MME 9 is equipped with a first receiver 11 for receiving the indicator of the type of service from PGW/SGW 8. As described above, the indicator of the service type indicates the type of service used in the session are processed MME 9, and associated with bearing channels used for the session. The machine-readable storage media as memory 12 is used for storing the indicator of the type of service. In the case of transferring a session from one access type to another, a second receiver 13 receives (from the eNodeB 10) indicating that the session should be postponed. The processor 14 is provided for the determination of carrier channels associated with the session, using the indicator of the type of service, and initiating transfer of the session, with the use of these bearers.

MME 9 can also be equipped with a first transmitter 16 for communication with the MSC Server 4 when you want to send the set the service type to the MSC Server to allow the MSC Server 4 to allocate resources or to use a special procedure. Also may be provided to the second transmitter 17 to inform the UE 1, which is involved in the session, which is involved in the SRVCC procedure for the type of service, and transmit the instructions of bearers associated with the session.

The memory 12 can also be used for storage to�mutarnee program 18, which when executed by the processor 14, and instructs the MME 9 to operate in accordance with the way described above.

As described above, the message includes an indication of the type of service used in the session. The processor 24 is provided to create or initialize bearers for the session and determine an indicator of the type of service to use when the last�during the transfer of the session from the access network packet-switched network access circuit-switched channels. This definition may either consist of indicator creation service type, or it can be passed from node 6 P-CSCF. The transmitter 25 is provided for sending PGW/SGW 8 indicator type services then forwarded to the MME 9.

In addition, UE can use multiple bearers with the same QCI value, not the risk that the "wrong" bearer will be transferred during the migration, or by limiting to one the number of bearer uses only one type. The above procedures will also allow the network operator to make a choice in respect of QCI values used for video calls, that provides sufficient flexibility to allow different operators to use different values for QCI video, as well as different QCI values for different subscribers.

SUBSTANCE: description is given of a method and device for switching wireless terminal channels. For this, several communication channels with different physical characteristics are supported in the cell of the base station. Each wireless terminal controls several channels and evaluates several channels at the same time, such that, there can be fast switching between channels. Information on the quality of the channel is sent from each wireless terminal to the base station. The wireless terminal or base station selects the channel, based on the evaluated quality of the channel. By supporting several channels and through periodical changes in channels in different implementation alternatives, the time taken before the wireless terminal finds good or suitable channel conditions is minimised, even if the wireless terminal changes position. Several antennae are used at the base station for simultaneous support of several channels, for example, through control of the directional pattern of the antennae.

EFFECT: reduced delays before wireless terminal finds suitable channel conditions.
