    FIELD OF THE INVENTION
    [0001] The present invention relates to wireless communications and specifically refers to a method for updating a Multimedia Broadcast / Multicast Service (MBMS) session. BACKGROUND OF THE INVENTION
    [0002] Currently, according to the conclusion of the Service Aspects and System 2 Working Group (SA2), an ongoing MBMS session may change some characteristics of the service, for example, the service area. An Evolved Packet Core (EPC) network defines an MBMS Session update procedure. However, in a radio access network (RAN), there is no corresponding procedure definition especially in M3 (an interface between an MME Mobility Management Entity and an MCE Multi-cell / Multicast Coordination Entity) and M2 interfaces (an interface between the ECM and an eNB). Upon receiving an MBMS Session Update Request message from a Broadcast / Multicast Service Center (BMSC), an MBMS gateway sends different messages to the MME based on different results of comparison between a list of updated control nodes included with it same and the list of updated control nodes included in the MBMS Session Update Request message, where the different messages can be MBMS Login Request, MBMS Stop Session Request, and MBMS Session Update Request. The MME must send these messages to its corresponding MCE. Therefore, on the M3 and M2 interfaces, the processing of the MBMS Session Update procedure needs to be defined. The processing comprises a new M3 application protocol (M3AP) and M2 application protocol (M2AP) signaling flow definition for the MBMS Session Update procedure, and a relevant processing mechanism for MBMS Session Update signaling from M3AP and M2AP on MCE and eNB. SUMMARY OF THE INVENTION
    [0003] Therefore, in order to solve the above problem, the present invention provides a method for processing the MBMS session update.
    [0004] In accordance with an aspect of the present invention, a method is provided for processing the MBMS Multimedia Broadcast / Multicast Service update session, comprising: the sending, by an MME Mobility Management Entity, of a first message MBMS session update request for a Multi-cell / Multicast MCE Coordinating Entity; processing, by MCE, of the first MBMS session update request message, and sending a second MBMS session update request message to an eNB and sending a first return message to the MME; and processing, by eNB, of the second MBMS session update request message, and sending a second return message to the MCE.
    [0005] Preferably, processing by the MCE of the first MBMS session update request message includes: decoding the first MBMS session update request message, and storing the session update attributes obtained by decoding in a context of MBMS support.
    [0006] Preferably, the processing by ENB of the second MBMS session update request message includes: decoding the second MBMS session update request message, comparing a service area that is already stored in a support context MBMS, with a new service area, and carry out the corresponding update.
    [0007] Preferably, after MCE correctly processes the first MBMS session update request message, MCE immediately sends a first MBMS session update response message to the MME.
    [0008] Preferably, after MCE receives a second MBMS session update response message from eNB, MCE sends a first MBMS session update response message to MME.
    [0009] Preferably, if the MCE is unable to correctly process the first MBMS session update request message received, the MCE sends a first MBMS session update failure message to the MME. More preferably, if the MCE sends the first MBMS session update failure message to the MME, the MME re-sends the first MBMS session update request message to the MCE.
    [00010] Preferably, after eNB correctly processes the second MBMS session update request message, eNB sends a second MBMS session update response message to MCE.
    [00011] Preferably, if eNB does not correctly process the second MBMS session update request message, ENB sends a second MBMS session update failure message to the MCE. More preferably, if eNB sends the second MBMS session update failure message to MCE, MCE re-sends the second MBMS session update request message to eNB.
    [00012] The present invention allows the RAN and EPC to consistently process the MBMS session update procedure. Thus, the present invention can avoid confusion caused by signal processing (i.e., the MBMS session update request message) from EPC to EUTRAN on the radio access network. BRIEF DESCRIPTION OF THE DRAWINGS
    [00013] The above and other characteristics of the present invention will become more evident through the detailed description below with reference to the drawings, in which, figure 1 illustrates a flowchart of a method for processing MBMS Session Update on the M3 and M2 interfaces according to an embodiment of the present invention; figure 2 illustrates a schematic diagram of an MBMS Session Update procedure between an MME and an MCE according to an embodiment of the present invention; and figure 3 illustrates a schematic diagram of an MBMS Session Update procedure between an eNB and an MCE according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE MODALITIES
    [00014] Next, by describing the specific modalities of the present invention with reference to the drawings, the principle and application of the present invention will become more apparent. It should be noted that the present invention is not limited to the specific embodiments below. It should also be noted that, for the sake of simplicity, these known components directly related to the present invention are not illustrated in the drawings.
    [00015] In TS23.246, an MBMS Session Update procedure is defined to update the Service Area for an MBMS transmission service session in progress by a BMSC. In section 8.8.4 of TS23.246, a detailed MBMS Session Update signaling procedure is described. This procedure is initiated by the BMSC, to modify the attributes of the Service Area and notify related eNBs to enter or leave the Service Area. Considering the existence of such a possibility as the change of the service area during the current session, it is reasonable for SA2 to define such a procedure. However, this does not involve a definition of interface signaling within a radio access network and a procedure for processing related network elements.
    [00016] There are three cases in which MBMS control plan nodes are changed due to the change of Service Area (SA), which are: Case 1: some new MMEs are added to a list of MBMS control plan nodes due to SA change; Case 2: it is necessary to remove some MMES from the list of MBMS control plan nodes due to the change of SA; Case 3: MMEs in the list of MBMS control plan nodes do not change, but the cells under these MMEs may change due to the SA change.
    [00017] In view of the above three cases caused by the change of SA, once the MBMS gateway receives signalization of Session Update Request from the BMSC, it compares a new list of control plan nodes with the list of control nodes. MBMS control plan already stored in an MBMS support context, and decide which case occurs. According to the description in TS23.246, the MBMS gateway sends different signals to corresponding MMEs based on different cases caused by the SA change, that is, for case 1, the MBMS gateway sends a Login Request message MBMS for any MME added to the new list; for case 2, the MBMS gateway sends an MBMS Session Stop Request message to any MME removed from the new list; For case 3, the MBMS gateway sends an MBMS Session Update Request (Temporary Mobile Group Identity (TMGI), flow identifier, QoS, MBMS service area, session identifier, estimated session duration, IP Multicast Addresses from transport network, IP address of a multicast source and Common End of Tunnel Identifier (C-TEID), etc.) for the remaining MMEs in the new list.
    [00018] The MME receives the Login Request message and the Session Stop Request message, and operates as usual, for example, creates or updates the MBMS support context and session attributes. The MME then notifies the related MCE by sending an M3AP Session Login Request and Session Stop Request flag. In this procedure, all processing on the related network nodes is consistent with the existing processing mechanisms for the MBMS Login Request and MBMS Session Stop Request.
    [00019] Next, the processing of an MBMS Session Update Request within a radio access network (NAR) will be described in detail with reference to figures 1 - 3.
    [00020] Figure 1 illustrates a flowchart of a method to perform an MBMS Session Update procedure on the M3 and M2 interfaces according to an embodiment of the present invention. Method 10 starts at step S100. In the M3 interface, first, it is necessary to define an elementary Class 1 procedure of MBMS Session Update Request message for the MBMS session, as specified in the following table: Table-1: Class 1 procedure defined for MBMS Session Update for the M3 interface

    [00021] In step S102, the MME sends a first MBMS session update request message to the MCE on the M3 interface. This message is used to notify the MCE of the changed characteristics (for example, the service area) of the continuous service session, and asks the MCE to update its parameters. A first MBMS session update request is specifically defined below: Table-2: Detailed definition of the MBMS Session Update Request Message for the M3 interface


    [00022] Note: the content in the line "Type and Reference IE" in the table corresponds to TS36.444 V.9.0.0.
    [00023] In step 104, the MCE processes the first MBMS Session Update Request message, sends a first return message to the MME, and sends a second MBMS Session Update Request message to eNB on the M2 interface. Specifically, the MCE updates its own parameters in the session, using the information in the first MBMS Session Update Request message, for example, the QoS parameter, the Service Area parameter, etc., stores the new session attribute update in the context MBMS support, and compares the original Service Area with a new Service Area. After that, the MCE sends the first return message to the MME on the M3 interface and sends the second MBMS Session Update Request message including the attributes of the new session to each eNB connected to it on the M2 interface. Depending on the result of the MCE processing, the first feedback message can be a first MBMS Session Update Reply message or a first MBMS Session Update Failure message. The first MBMS Session Update Reply message is used to report the success of the first MBMS Session Update Request message, while the first MBMS Session Update Failure message is used to report the failure of the first MBMS Session Update message. MBMS Session Update. Definitions for both messages are provided below: Table-3: Detailed definition of the MBMS Session Update Response Message for the M3 interface

    [00024] Note: the content of the line "Type and Reference IE" in the table corresponds to TS36.444 V.9.0.0. Table-4: Detailed Definition of Session Update Failure Message for M3 Interface

    [00025] Note: the content in the line "Type and Reference IE" in the table corresponds to TS36.444 V.9.0.0.
    [00026] Likewise, the Class 1 elementary procedure of the MBMS Session Update Request message is also defined for MBMS Session Update on the M2 interface, as specified in the following table: Table-5: Class 1 procedure defined for MBMS Session Update for M2 interface

    [00027] A second MBMS Session Update Request is specifically defined as follows: Table-6: Detailed Definition of the MBMS Session Update Request Message for Interface M2

    [00028] Note: the content in the line "Type IE and reference" in the table corresponds to TS36.443 V.9.0.0.
    [00029] In step S106, eNB processes the second MBMS Session Update Request message and sends a second feedback message to the MCE. Specifically, ENB processes the second MBMS session update request message, compares the Service Area stored in the context of MBMS support with the new service area, and performs the corresponding update. In addition, ENB sends the second return message to the MCE on the M2 interface.
    [00030] Likewise, depending on the result of the eNB processing, the second feedback message can be a second MBMS Session Update response message or a second MBMS Session Update Failure message. The second MBMS Session Update response message is used to report the success of the second MBMS Session update request message, while the second MBMS Session update failure message is used to report the failure of the second MBMS Session update message. MBMS Session update. Definitions for both messages are specified below: Table-7: Detailed definition of MBMS Session Update Response Message for M2 interface

    [00031] Note: the content in the line "Type and Reference IE" in the table corresponds to TS36.443 V.9.0.0. Table-8: Detailed definition of MBMS Session Update Failure Message for M2 interface

    [00032] Note: the content in the line "Type and Reference IE" in the table corresponds to TS36.443 V.9.0.0.
    [00033] Finally, method 10 ends at step S108.
    [00034] After receiving a response from the eNB, the MCE reports the result of the requested MBMS Session update to the MME. In different scenarios, the first feedback message sent from MCE to MME can include a plurality of cases. The MCE can immediately respond to MME to confirm receipt of the MBMS Session Request after receiving and correctly decoding the M3AP MBMS Session Update Request message, without waiting until all related eNBs have completed processing the second SMS message. MBMS session update request and then send the first MBMS Update Request Reply message to the MME. In addition, MCE may also send the first MBMS Update request response message to MME after receiving all second feedback messages indicating that all related eNBs have correctly processed the second MBMS session update request message. However, if the MCE determines that the radio access network is not adapted for the requested session update, the MME must be notified via the first MBMS Update Request Failure message. Alternatively, due to some reasons (for example, incorrect decoding, hardware failure, etc.), the MCE cannot correctly process the incoming session update request, and at this point, the MCE returns to the MME, via the first MBMS session update failure message. Alternatively, MME may consider resending the first MBMS session update request message to those MCES that have not failed to process.
    [00035] Depending on different cases, due to the change of service area, ENB may need to rejoin a group of multicast addresses from the MBMS service session and send the MBMS configuration information for a corresponding cell to prepare to receive the MBMS service session, eNB may also need to leave the original MBMS multicast address group session and stop receiving the MBMS service session; it is also possible that eNB only needs to adjust the transmission conditions of the MBMS service in the cells under its control, including the transmission of corresponding MBMS configuration control information. In these cases, eNB views the second MBMS update request reply message as the second feedback message to return to the MCE. Obviously, eNB may not correctly process the second MBMS session update request message received due to various reasons (for example, incorrect decoding, some hardware error, etc.) At this point, the related ENB would take the second Failure message Update Session MBMS as the second return message to respond to the MCE, in order to notify the MCE of the inability to successfully process the Session update request in the corresponding eNB. Alternatively, the MCE may resend the second MBMS session update request message to those eNBs that have failed to process.
    [00036] Figure 2 illustrates a schematic diagram of an MBMS Session update procedure between an MME and an MCE according to a modality of the present invention, in which the MME communicates with the MCE through the M3 interface. Figure 2 (a) represents the case where MCE successfully processes the first MBMS session update request message, and figure 2 (b) represents the case where MCE fails to process the first MBMS session request message. MBMS session update.
    [00037] Figure 3 illustrates a schematic diagram of an MBMS Session update procedure between an eNB and an MCE according to an embodiment of the present invention, in which the eNB communicates with the MCE through the M2 interface. Figure 3 (a) represents the case where eNB successfully processes the second MBMS session update request message, and figure 3 (b) represents the case where eNB fails to process the second MBMS session request message. MBMS session update.
    [00038] It should be noted that, for the sake of simplicity, figure 2 and figure 3 merely illustrate an MME and an ECM, as well as an ECM and an eNB, respectively. However, the present invention is not limited to them. An MME can have a plurality of associated MCEs, and each MCE can have a plurality of associated eNBs. Those skilled in the art will note that the MBMS Session update procedure described above can be applied to a radio communication system having a plurality of MMEs, MCEs, and eNBs associated with each other.
    [00039] Although the present invention has been illustrated above with reference to preferred embodiments of the present invention, those skilled in the art will note that without departing from the spirit and scope of the present invention, the present invention can be subjected to a variety of modifications, replacements and changes. Thus, the present invention should not be limited by the above modalities, but must be limited by the appended claims and their equivalents.
