The method comprises the following steps: any early-stage media negotiation with any user agency server UAS in a branched call is finished by a user agency client UAC; if another UAS is selected as an early-stage media sending party, any UAS is notified to stop sending early-stage media and keep attributes of the media unchanged; after receiving the notification sent by the UAC, the any UAS stops sending the early-stage media and keeps attributes of the media unchanged according to the notification. According to the method and the device provided by the invention, conventional media can be prevented from being deleted under the condition that the call is branched in a gateway mode.
Description
Technical field
The present invention relates to communication technical field, the method and apparatus that particularly a kind of gateway mode lower bifurcation is called out.
Background technology
The purpose of in telephone network, calling out is in order between calling subscriber and called subscriber, to set up conversation; The medium that transmit between calling subscriber and the called subscriber before conversation is set up are Early media; For example ring-back tone, CRBT etc., it is conventional medium that the medium that transmit between back calling subscriber and the called subscriber are set up in conversation.
Transmit Early media, need between calling subscriber and called subscriber, carry out early media negotiation, set up media session.In order to realize conversation initialized protocol (Session Initiation Protocol; SIP) transmission of Early media in the session; RFC3960 proposes to be used for the gateway mode and the application server pattern of early media negotiation; The realization of gateway mode is comparatively simple, and present most telephone systems all adopt gateway mode to consult Early media.
Referring to Fig. 1, Fig. 1 is the interaction diagrams of early media negotiation under the gateway mode, may further comprise the steps:
Step 101, User Agent Client (UAC also is calling subscriber's a sip terminal) send call request (INVITE) to User Agent Server (UAS also is called subscriber's a sip terminal), carry the offer that has media negotiation;
Step 102, UAS reply 183 interim reliable response, carry to consult successful Early media answer;
Step 103, UAC send PRACK to UAS and confirm 183 interim reliable response;
Step 104, UAS reply 200OK and confirm, the early media negotiation of completion and UAC is set up early-session.
Step 105, UAS send Early media to UAC;
Step 106, UAS off-hook answering call are replied the 200OK response, and are stopped to send Early media;
Step 107, UAC send ACK to UAS and set up calling, switch to conventional session from early-session;
The mutual conventional medium of step 108, UAC and UAS are realized both sides' conversation.
Gateway mode uses simple interaction flow to accomplish the negotiations process of Early media, is used widely.Yet gateway mode can't the good treatment bifurcation call, describes below in conjunction with Fig. 2:
Fig. 2 is the process chart that the gateway mode lower bifurcation is called out, and may further comprise the steps:
Step 201, UAC send call request INVITE to UAS1 and UAS2 simultaneously.
Step 202-205, UAS1 and UAC accomplish early media negotiation, send Early media to UAC.Negotiations process is identical with step 102-105 among Fig. 1.
Step 206-208, UAS2 and UAC accomplish early media negotiation; Negotiations process is identical with step 102-104 among Fig. 1.
Step 209, UAC have selected UAS1 as Early media broadcast side, receive the Early media from UAS1, and it is quiet therefore to UAS2 transmission UPDATE (MUTE) request UAS2 being set.
It is corresponding that step 210, UAS2 are replied 200OK, and be quiet according to the medium property that UPDATE (MUTE) request of UAC is provided with self.
Step 211, t1 be the UAS2 off-hook constantly, sends the 200OK response to UAC, and the called subscriber begins speech; Because it is quiet that the medium property of self is set to, USA2 can not send the Media Stream (yet being the conventional medium that the called subscriber talks and produces) of called subscriber's speech to UAC.
Step 212-213, UAC send the CANCLE cancellation to UAS1 and call out, and send ACK foundation to UAS2 and call out.
Step 214, UAC send the quiet of UPDATE (UN MUTE) request cancellation UAS2 to UAS2.
Step 215, UAS2 reply 200OK and confirm, and, completion media re-negotiation (t2 constantly) quiet according to UPDATE (UN MUTE) the request cancellation of UAC.
After step 216, the completion media re-negotiation, the mutual conventional medium of UAS2 and UAC.
In the process of above-mentioned processing bifurcation call; Because the t1 state of (moment that called off-hook begins to talk) to the t2 moment (moment that quiet heavily the consulting of UAC request cancellation UAS2 accomplished) UAS2 constantly is quiet (inactive); Can not send any Media Stream, cause the Media Stream of called subscriber's speech in the t1-t2 time to be lost to UAC.It is thus clear that, in the realization that existing gateway pattern lower bifurcation is called out, delete the problem of cutting from having conventional medium after Early media switches to conventional medium, cause the beginning part loss of voice of talking behind called subscriber's off-hook.
