The embodiment of the invention provides a method for realizing multimedia communication, which comprises the steps of: receiving a multimedia call request sent to a called terminal by a multimedia calling terminal by a mobile switching center (MSC), sending a search request for obtaining a multimedia calling route of the called terminal to a called home location register (HLR) according to the call request, and if the multimedia calling route of the called terminal is in failure in obtaining, sending a connecting request comprising an audio calling roaming number to a multimedia service platform so as to be convenient for initiating audio connection to the called terminal by the multimedia service platform according to the audio calling roaming number and initiating multimedia connection to the multimedia calling terminal. Meanwhile, the invention also provides corresponding device and system. The embodiment of the invention inhibits the falling of the multimedia calling, and greatly improves the success rate of multimedia communication.
Description
technical field [0001] The present invention relates to the field of network communication, in particular to a method, device and system for realizing multimedia communication. Background technique [0002] The mobile multimedia phone service is a multimedia communication service that provides any combination of media formats such as real-time video, audio or data on the wireless network. Perform real-time audio, video, and other interactions. That is, the two parties in the call can see each other's scenes during the call. [0003] Multimedia telephony can be implemented in packet mode or circuit mode. For example, multimedia telephony services can be implemented based on wideband code division multiple access WCDMA or time division-synchronous code division multiple access TD_SCDMA circuit domain (CS) bearer. [0004] In the early stage of 3G (third-generation mobile communication network) network construction, the network coverage area is small, the wireless resources a...
