From said process as can be seen, between terminal in the process of media transfer, when same medium repeatedly shift between different terminals, for example: medium 1 are transferred to UE3 by UE2 again after being transferred to UE2 by UE1, because media transfer source terminal equipment (promptly being the equipment that produces medium) has been preserved the conversation media transinformation when shifting successfully, then the information of medium 1 will all have preservation in UE1 and UE2, and these information are in the preservation that repeats of terminal room, wasted the system resource of terminal equipment greatly, further, also make in the subsequent session operation (for example medium obtain), this media information synchronously, renewal or use etc. are comparatively complicated.
In the prior art, also has a kind of terminal equipment UE1 ' from terminal equipment UE2 ', obtain the method for the part or all of medium in the ongoing Multimedia session, the implementation procedure of this method is: UE2 ' and opposite end UE ' set up after the session, UE1 ' by SCC AS (for example: the dialogue event information bag of subscribing to UE2 ') obtain the ongoing session information of UE2 ', according to described session information, UE1 ' sends Invite message to SCC AS, request is obtained relevant conversation media and is set up session from UE2 ', comprise described relevant conversation media information in the SDP message body of Invite message, be used to refer to the conversation media that expectation is obtained; Successfully set up after the session branch between UE1 ' and the SCC AS, SCC AS sends re-Invite message to opposite end UE ', upgrade far-end session branch (opposite end UE ' is connected with SCC AS's), send re-Invite message to UE2 ' simultaneously, indication UE2 ' stops the medium that transmission/reception has been obtained by UE1 ', thus the session branch between renewal and the SCC ASUE2 '; If all medium of this session are all transferred to UE1 ' among the UE-2 ', SCC AS will discharge and UE2 ' between Multimedia session.
As can be seen, in the medium acquisition process that carries out between the terminal, initiate the terminal equipment (for example UE1 ') that medium obtain, obtain conversation media information by the dialogue event information bag of subscribing to other terminal equipment (for example UE2 '), this just needs to set up the session information subscribing relationship by network and other terminal equipment in advance, and the process that makes medium obtain is comparatively complicated; Further, if the session related media that obtains when being stored in a plurality of terminal, need be set up a plurality of subscription procedure, taken more network service resource.
