Problems solved by technology
[0015] The second method mentioned above is to implement the process of service fallback or service change. It is necessary to start the modification process on the calling user side, the called user side and the network side to carry out a comprehensive modification of the entire service channel. The modification process is complicated and time-consuming. Long extension, difficult to meet user requirements
[0016] Moreover, this method is completely based on the specification process given by the user equipment and the network supporting dual BCIE. There is no solution for user equipment that only supports single BCIE, but a considerable proportion of user equipment that has been sold now only supports Single BCIE user equipment, they also have the need to implement service fallback or service change
[0017] To sum up, the above two methods for implementing multimedia service fallback or service change both have the problem of long delay and difficulty in meeting user requirements; and method one can only achieve service fallback, but cannot achieve service change; method two only It can implement service fallback or service change for user equipment that supports dual BCIE, but it can’t do anything for user equipment that only supports single BCIE
Furthermore, neither of the two methods can solve the service change problem that only supports single BCIE user equipment

Embodiment Construction
[0067] The present invention provides a system, method and information processing device for realizing multimedia service change. In a preferred embodiment, the process of multimedia service change is completed by adding functional units capable of processing media streams and H.245 signaling , the multimedia service change includes multimedia service fallback and service change.
[0068] At present, the standard for multimedia mobile user equipment in the circuit domain that needs to implement multimedia service fallback or service change is the H.324M protocol. User equipment using this protocol performs point-to-point interoperability through in-band negotiation signaling H.245, and the transmitted media Streams are multiplexed by audio streams, video streams, data streams, and H.245 signaling through the H.223 protocol. Different stream types correspond to different logical channels, and H.245 signaling messages can be used for different logical channels. Channels are open...

The invention discloses an information disposal device, which consists of multiplying or demultiplying mode and signaling disposal mode, wherein the device controls logical channel between one end of user equipment and information disposal device when it receives business changing information from mobile switching center, which realizes multimedia business changing. The invention also provides realizing system to change multimedia business, which consists of relative device and user equipment, wherein the user equipment interacts signal through information disposal device when it receives business changing information from mobile switching center, which realizes multimedia business changing. The invention is rapid to descend multimedia business or change business, which is fit for user equipment of single and double BCIE.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a system, method and information processing device for realizing multimedia service change. Background technique [0002] Compared with the second generation wireless communication technology (2Generation, 2G), the third generation wireless communication technology (3Generation, 3G) has a very significant difference, that is, the 3G network circuit domain can provide multimedia services including video telephony. [0003] When using the 3G network to provide multimedia services to users, users may need to implement multimedia changes due to various reasons, such as multimedia service drop or service change. [0004] A typical situation of the service fallback is that when a terminal supporting video calls, that is, a user equipment (User Equipment, UE) initiates a video call, but due to various reasons, the video call fails, but the network and the user The status of the ...
