Embodiment
Introduce two kinds of feasible conversation media transfer methods below.
First method is that terminal equipment UE1 and opposite end UE (remote UE) set up a Multimedia session, when the UE1 decision is arrived target terminal equipment UE 2 with the one or more media transfer in the session, UE1 initiates the media transfer request to SCC AS, set up (media transfer) request by SCC AS to the UE2 initiation session again, thereby realize the transfer of IMS conversation media between UE1 and UE2.First kind of conversation media transfer flow be as shown in Figure 3:
Step 301, the UE1 decision is arrived UE2 with the one or more media transfer in the session.
Step 302-305, UE1 sends REFER (transfer) message to SCC AS, and the request media transferring is to UE2.This REFER (transfer) message has been indicated the behavior (media transferring is to another equipment), media transfer target device, media information to be transferred (for example the dialogue that is associated of medium type, medium etc.) of request.SCC AS permits this request, promptly examines UE1 and has the right to ask media transferring and initiate the media transfer process to UE2.
Step 306-309, SCC AS obtains the ability information of UE2 (media transfer target device), for example medium type of Zhi Chiing, coded system etc. by OPTION (selection) message.
Step 310-314b, SCC AS sends INVITE (invitation) message to UE2, and session is set up in request, wherein carries the parameter (for example medium type, coded system etc.) of the media transferring of advising based on the ability of terminal UE 2.UE2 carries out the affirmation of media parameter and the media parameter of confirming is sent to SCC AS by 200 OK response messages, and begins transmission/receiving data stream.After SCC AS receives replying of UE2, reply the ACK acknowledge message.
Step 315-319b, SCC AS sends re-INVITE (inviting again) message to opposite equip., upgrades the far-end session branch.The parameter of carrying the media transferring that UE2 confirmed among the step 313-314 in this re-INVITE message.Opposite end UE replys 200 OK after receiving the parameter of described media transferring, and begins this Media Stream of reception/transmission.
Step 320-324b, SCC AS sends re-INVITE message to UE1, the parameter of the media transferring that wherein carries UE2 and confirmed, indication UE1 stops to send/receiving the medium that migrated out.UE1 replys 200 OK after receiving new media parameter, and stops this Media Stream of transmission/reception.
Above-mentioned steps 315-319b and 320-324b can executed in parallel.
If UE1 has transferred to UE2 with whole medium of this session, then behind step 319b, SCC AS sends session to UE1 and discharges (BYE) message, the session between release and the UE1; UE1 replys 200 OK, and discharges session; And can execution in step 320-324b.
Second kind of conversation media transfer method is that terminal equipment UE1 initiates media transfer request (without SCC AS) to target terminal equipment UE 2, set up (media transfer) request by UE2 to SCC AS initiation session again, thereby realize the transfer of IMS conversation media between UE1 and UE2.As shown in Figure 4, these method concrete steps are as follows:
Step 401, UE1 and opposite end UE set up a Multimedia session.
Step 403-410, UE1 sends REFER (transfer) message to UE2, and the request media transferring is to UE2.This REFER (transfer) message has been indicated the behavior (media transferring is to another equipment), media transfer target device, media information to be transferred (for example the dialogue that is associated of medium type, medium etc.) of request.UE2 replys 202 Accepted (acceptance) message, accepts this transfer request.
Step 411-414, UE2 sends INVITE (invitation) message to SCC AS, and session is set up in request, wherein carries UE1 media transfer relevant information.Wherein step 413 is carried out service logic for S-CSCF, promptly according to initial filter criteria (iFC:initial Filter Criteria), gives SCC AS with INVITE (invitation) forwards.
Step 415, after SCC AS received INVITE, the session that request is set up was associated with original session (being about to new UE2 session access tributary is associated with the far-end session branch), and begins to carry out media transfer.
Step 416-421, SCC AS sends re-INVITE message to opposite equip., upgrades the far-end session branch.
Step 422-427, SCC AS sends media transfer success (200 OK) message to UE2.UE2 replys and confirms (ACK) message.
Step 428-436, SCC AS sends re-INVITE message to UE1, and indication UE1 stops to send/receiving the medium that migrated out.
Step 437-440, UE2 sends notice (NOTIFY) message by S-CSCF to UE1, and notice UE1 media transfer process finishes.UE1 replys 200 OK message.
If UE1 has transferred to UE2 with whole medium of this session, then after step 427, SCC AS sends session to UE1 and discharges (BYE) message, the session between release and the UE1; UE1 replys 200 OK, and discharges session; And can execution in step 428-436.
