Abstract
The invention provides a method and system for carrying out a multimedia-conference notification service between an NGN and an IMS, wherein the method for a gateway to transmit a multimedia-conference notification service message between the IMS and the NGN includes the following steps: receiving a conference subscribed message sent by a multimedia-conference service application server (AS) of one of the IMS and the NGN; and forwarding the conference subscribed message to a multimedia-conference service AS of the opposite party. The method and system realize connection establishment of users of the IMS or the NGN with an AS under a network of the opposite party.
Description
Technical field
The present invention relates to the intercommunication of multimedia conference service between IP Multimedia System (IMS) and next generation network (NGN), relate in particular to the method and system of carrying out multimedia conferencing notification service between a kind of NGN and IMS.
Background technology
Multimedia conference service mainly provides long-range audio/video and data conferencing service by Media Resource Server (MRS) and service application service device (Aplication Server, AS) for each participant member.Multimedia conferencing member can subscribe to conference status, obtains meeting field information, conference member list etc.
Multimedia conference service has had large-scale application under the NGN network architecture.IP Multimedia System (IMS), as network of new generation, is subject to operator and more and more pays close attention to, and many business have obtained good application under IMS, and multimedia conference service is exactly a wherein application.
Be subject to the restriction of Operator Specific Service Promotion Strategy, IMS and NGN will coexist within considerable time from now on, produce based on this demand that multimedia conference service carries out intercommunication between above-mentioned two kinds of networks.The intercommunication of multimedia conference service under present stage IMS and NGN dis environment, only limits to by IMS or NGN, the member in bipartite network be invited into the multimedia conference service of setting up in present networks.And the multimedia conferencing notification service message of characteristic under IP network: meeting subscribe message (SUBSCRIBE) and conference status notice (NOTIFY), also cannot intercommunication between two networks.
Fig. 1 has provided the composition structure chart of prior art multimedia conferencing, and the composition of multimedia conferencing is identical in two networks.Carry out multimedia conference service in IMS or NGN network time, UE need to be mutual by core net and multimedia service application server (AS).But under NGN, because the spontaneous defect of existing Softswitch can not realize the forwarding of SUBSCRIBE message and NOTIFY, so the transmission of this type of message is by UE and AS direct interaction.But IMS network but can be supported the processing of this type of message completely.
Fig. 2 has provided the multimedia conferencing Signalling exchange flow chart in prior art IMS or NGN.
S201~S211, UE1 initiates to create the INVITE request of multimedia conferencing, and service application service device AS accepts after request, sends INVITE to MRS server application media resource, between MRS and UE1, completes media negotiation, sets up media channel;
S212~S213, AS sends INFO and creates multimedia conferencing to MRS server, and UE1 is joined to multimedia conferencing;
S214~S221, UE1 sends the meeting field information of SUBSCRIBE message subscribing multimedia conferencing to AS, and AS returns to UE1 by NOTIFY can field information;
S222~S246, UE1 sends REFER message and invites UE2, AS receives after this REFER message, sending INVITE invites UE2 to add multimedia conferencing, UE2 receives that returning to 183 message after invitation brings AS by the media of UE2, and AS sends INVITE and completes the media negotiation between MRS server and UE2 to MRS server;
S247~S248, AS sends INFO, to MRS server, UE2 is joined to multimedia conferencing;
S249~S256, UE2 sends the meeting field information of SUBSCRIBE message subscribing multimedia conferencing to AS: under IMS network, this message is forwarded to AS (as shown in FIG.) by core net; Under NGN network, this message is walked around Softswitch, directly from UE2 to AS, (in figure, does not mark); AS returns to UE2 by NOTIFY can field information.
According to the multimedia conferencing Signalling exchange flow process in existing IMS or NGN, if there is the user who belongs to respectively IMS and NGN in the user of multimedia conferencing, when the user of IMS or NGN wishes to send meeting subscribe message to the multimedia conference service application server AS of working under bipartite network, and while obtaining multimedia conferencing information, because the Softswitch of NGN cannot forward meeting subscribe message and conference status notification message, cause IMS or NGN user cannot with bipartite network under application server AS connect.
Summary of the invention
