The MSC that is built-in with above-mentioned VIG unit on the one hand can will be H.245 signaling, audio stream and video flowing from the H.324M multimedia data stream demultiplexing of 3G portable terminal, and audio stream and video flowing sent to fixed communication network, on the other hand can also be with audio stream and the multiplexing H.324M multimedia data stream that becomes of video flowing from fixed communication network, send to corresponding 3G portable terminal, thereby can realize the multimedia interconnection between 3G network and the fixed communication network.
And, because MSC of the present invention is built-in with the VIG unit, can realize the VIG function in the inside of MSC, therefore, compare with the method for external VIG in the prior art, can reduce networking and operation and maintenance cost, and for particular services such as for example multimedia color ring back tones, there is not alternate route in its calling procedure, thereby can additionally not take the resource of MSC yet.
To utilize the MSC of built-in VIG function to realize the 3G network and the method for network multimedia intercommunication H.323 by specific embodiment explanation below.Fig. 3 has shown that MRS in 3G portable terminal and the fixed communication network carries out the idiographic flow of multimedia interconnection, may further comprise the steps:
A1:3G portable terminal (MS) sends the MGC of SETUP (foundation) message to MSC when making a call;
A2:MGC goes out this calling according to the SETUP message detection that receives and is multimedia call, and analyze should be with call proceeding behind the MRS of fixed communication network, by the standard Add (Mux of agreement H.248, Ra, Rb) message (increasing end points message) is distributed Multiplexing module Mux, audio endpoint Ra and video endpoint Rb to the built-in VIG request of MG for this multimedia call;
Wherein, (Rb) Mux, Ra in the message bracket and Rb are the entrained parameter of described increase end points message to Add for Mux, Ra;
A3:MG by standard H.248 the Add-Ack of agreement (Rb) message (increase end points response message) is returned by described built-in VIG and is distributed Session Description Protocol (SDP) attribute of Multiplexing module Mux and audio endpoint Ra, video endpoint Rb to MGC for Mux, Ra;
(Rb) message is that the Multiplexing module Mux of this call distribution and the SDP attribute of audio endpoint Ra, video endpoint Rb send to MGC by the Mux in the bracket, Ra and Rb parameter with MG to above-mentioned Add-Ack for Mux, Ra;
A4:MGC sends INVITE (invitation) message to MRS, and carries the SDP attribute of audio endpoint Ra and video endpoint Rb in this message, will inform MRS from the resource as this call distribution, carries out capability negotiation with MRS;
After A5～A7:MRS was known the resource allocation conditions of this calling, response 180 (rings) and 200 (called party answer) message were to MGC, and next MGC sends Connect (connection) message to MS, and instruct MS MRS replys, and this calling is set up;
A8～A10:MS start and MGC between H.324M capability negotiation handling process, by TCS (terminal capabilities set) message in the signaling H.245, MSD (principal and subordinate's decision) message and OLC (opening logic channel) message and MGC carry out capability negotiation;
Need to prove, in this step, described TCS, MSD and OLC message all are multiplexing H.245 signalings in described H.324M multimedia data stream, because VIG function that the MG in the present embodiment is built-in, therefore, MG calls out the Multiplexing Unit Mux that is distributed for this can go out H.245 signaling message by demultiplexing from described H.324M multimedia data stream, and these signaling messages are sent to MGC, finishes described capability negotiation process;
Described capability negotiation process specifically comprises:
At first, the ability that MS supports by TCS information reporting portable terminal self Voice ﹠ Video in the signaling message H.245, ability that MGC reports according to MS and the corresponding resource of self supporting of capability distribution are fed back the Voice ﹠ Video tenability of this MGC itself again to portable terminal by the TCS message in the signaling message H.245;
Then, MS and MGC consult H.324M multiplexing rule and other relevant parameters of multimedia data stream sound intermediate frequency stream and video flowing by the MSD message in the signaling message H.245 again, for example the code encoding/decoding mode that is adopted etc.; Described multiplexing rule promptly be H.324M in the multimedia data stream which logic channel carrying be audio stream, which logic channel carrying be video flowing;
At last, MS and MGC are the corresponding logic channel of this call distribution by the OLC message in the signaling message H.245;
In this step, if the result of this capability negotiation is consistent with the capability negotiation result of MRS with MGC, then directly carry out the multimedia communication process, if and negotiation result is inconsistent, then need by between Multiplexing module Mux, the audio endpoint Ra of MG and video endpoint Rb, inserting corresponding encoding and decoding conversion resource TC, finish the conversion of Streaming Media coding, realize the adaptive of multimedia tenability between MS and the MRS;
In the described capability negotiation process of above-mentioned A4～A10, MGC also can at first carry out capability negotiation with MS, carries out capability negotiation according to negotiation result and MRS again, and can not exceed the scope that this invention is intended to protect, in this case, the inconsistent situation of negotiation result can not appear;
A11: after capability negotiation was finished, MS and MRS carried out the multimedia communication process;
Before carrying out the multimedia conversation, MGC has been known the multiplexing rule of described H.324M multimedia data stream sound intermediate frequency stream and video flowing according to the MSD message of transmitting in the negotiations process, like this, in the multimedia communication process, Multiplexing module Mux among the configuration MG will resolve into audio stream and video flowing from the H.324M multimedia data stream of MS according to described multiplexing rule, and send to MRS by audio endpoint Ra and the video endpoint Rb that distributes among the MG, or will be from MRS, audio stream and the multiplexing H.324M multimedia data stream that becomes of video flowing by audio endpoint Ra and video endpoint Rb reception, send to MS, thereby realize the multimedia interconnection between MS and the MRS;
A12～A15: when this end of conversation, MS closes the logic channel that this multimedia communication is set up by CLC (closing logic channel) message request MGC, sends REL (release) message then and carries out normal call-closure flow process to MGC; MGC and MRS finish this multimedia call by BYE (goodbye) message and response message 200.
In above-mentioned steps, CLC message also is multiplexing H.245 signaling in described H.324M multimedia data stream, therefore, also needs the Multiplexing Unit Mux among the MG that described H.324M multimedia data stream is carried out demultiplexing, just can obtain described CLC message.
Because the described method of present embodiment has realized the function of VIG in the inside of MG, therefore, MSC does not need and external VIG carries out just can realizing alternately and fixed communication network between multimedia interconnection, the construction and the operation maintenance cost of having saved network greatly; In addition, because MG can insert corresponding TC between Multiplexing module Mux, audio endpoint Ra and video endpoint Rb, carry out transcoding, coding transform, therefore, MSC and MRS and with the inconsistent situation of the capability negotiation of MS under still can realize multimedia interconnection, and do not need negotiations process again, and simplified the handling process of MGC greatly, also can avoid simultaneously the problem of the MSC billing error that occurs in the existing method.
The foregoing description only is the method for carrying out multimedia interconnection with 3G portable terminal and fixed communication network MRS, use said method MS can also with fixed communication network in can carry out capability negotiation fixed communication network multimedia service network element directly carry out multimedia interconnection.H.323 or the multimedia terminal of other fixed communication networks for example, described fixed communication network multimedia service network element can be.
