[0065] Shown in Fig. 4 is that the present embodiment realizes the flow process of MMSC user session merging scene one, and this moment, MMSC session merges with the session being set up, comprises the following steps:

[0066] 401) The MMSC user initiates a session S1 to the remote user B in the access network A, and decides to merge the session S1 with the session S2 initiated by the UE-A to the remote user B while accessing the network B;

[0067] The access network A may be a PS domain or a CS domain. In addition, symbols such as "S1" in this application are only used to distinguish multiple sessions described, and do not refer to any specific session.

[0068] 402) The MMSC user equipment UE-A initiates a session request for session S1 to the remote user equipment UE-B, which includes indication information merged with session S2, and the session request is sent to the serving call session control function (Serving- Call Session Control Function, referred to as S-CSCF), ...

[0084] FIG. 5 shows the flow of the present invention to realize the second scenario of MMSC user session merging. At this point, a session S has been established between the MMSC user UE-A and the remote user equipment UE-B, and the MMSC user decides to merge the newly initiated session S1 with the established session S, including the following steps:

[0085] 501) The MMSC user decides to initiate a session S1 to the remote user B in the access network A, and decides to merge the session S1 with the established session S between UE-A and the remote user B;

[0086]502) The MMSC user equipment UE-A initiates a session request for session S1 to the remote user, which includes an indication of merging session S1 and session S, and the session request is sent to the S-CSCF of the home IMS network, and the intermediate process and path omit;

[0087] 503) Triggered according to initial filter criteria (initial Filter criteria, referred to as iFC), the S-CSCF sends a SIP session ...

Abstract

The invention relates to a conversation combination method of a multimedia session continuous service, which is applied in an IP multimedia secondary system, when multimedia session continuous service MMSC user needs to combine a session S1which is launched in a multimedia service and other sessions, session request which is launched by MMSC user equipment comprises receiving the indication information of combing the session S1 and other sessions, a MMSC applied server obtains the combined indication information from the received session request according to local strategy judgment, if the session S1 is permitted to combine with other sessions, and then the session S1 and other sessions are combined after session requests of all the sessions which are launched by MMSC user equipment and are needed to be combined are received. The invention can more flexible to process the combination of conversion, which can not only reflects the willing of users, but also can finish the control of network.

Description

technical field [0001] The invention relates to the field of communication, more specifically to a method for implementing session merging in IMS domain multimedia session continuity and centralized control services. Background technique [0002] IP (Internet Protocol, referred to as IP) multimedia subsystem (IPMultimedia Core Network Subsystem, referred to as IMS) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3GPP) , which builds an open and flexible service environment, supports multimedia applications, and provides users with rich multimedia services. [0003] IMS is an IP-based telecommunications network architecture and has nothing to do with access technology. In addition to providing services for packet access networks such as GPRS (General Packet Radio Service) and WLAN (Wireless Local Area Network, wireless local area network), it also provides It can provide services for mobile cellular networks such as GSM (Global System ...
