Abstract

The invention discloses a method for implementing multimedia color ring service without speech path rerouting, comprising the steps of: MSC calls a called terminal according to the call initiated by a calling terminal, and the called terminal returns call response information according to the call; MSC receives the call response information and then informs MRBT of a to-be-played color ring type and switches on the speech path between the calling terminal and MRBT; after the calling terminal and MRBT successfully makes the first media negotiation, MRBT plays multimedia color ring for the calling terminal. And it also discloses a system for implementing multimedia color ring service without speech path rerouting. And it can make network side equipment provide multimedia color ring service in a speech path control mode completely consistent with that of voice color ring service.

Description

Technical field [0001] The present invention relates to multimedia color ring back tones technology, in particular to a method and system for realizing a detour multimedia color ring back tone service without a voice path. Background technique [0002] The voice ring back tone is a piece of customized music or voice that is ordered by user A or user B or a third party to play to user A when user A calls user B. With the construction of the third-generation mobile communication system version 4 (3G R4), 3G R5, and next-generation network (NGN), users have put forward video requirements for communication, and multimedia color ring back tone services have emerged. Multimedia CRBT is an extension of voice CRBT to multimedia. It is a customized multimedia clip that is ordered by User A or User B or a third party to play to User A when User A calls User B. Here, the multimedia clip includes video and Audio. [0003] The prior art mainly transforms the network equipment on the basis of ...
