Method and system for implementing non-speech channel alternate multimedia color ring service

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 invention relates to multimedia color ring technology, in particular to a method and system for realizing multimedia color ring service without voice path detour. Background technique [0002] Voice ring back tone is a customized music or voice ordered by user A or user B or a third party to be played to user A during the process of user A calling user B. With the construction of the third-generation mobile communication system version 4 (3G R4), 3G R5 and the next-generation network (NGN), users have put forward video requirements for communication, and the multimedia ring back tone service has appeared accordingly. Multimedia CRBT is an extension of voice CRBT to multimedia. It is a customized multimedia segment ordered by user A or user B or a third party to play to user A during the process of user A calling user B. Here, the multimedia segment includes video and audio. [0003] In the prior art, the network equipment is mainly transformed on...

Problems solved by technology

[0020] 1. It is necessary to upgrade the existing network equipment so that the MSC of the end office of the whole network supports VIG capability and SIP protocol, but the investment and cost of upgrading the network equipment are large;

[0021] 2. This solution has a great impact on the capacity of network equipment, which will lead to a serious decline in the performance of network equipment

[0032] 1. It is necessary to upgrade the existing network equipment so that MRBT supports VIG capability and SIP protocol, but the investment and cost of upgrading the network equipment are large;

[0033] 2. Resources are occupied during the entire call process, which requires extremely high reliability and stability of MRBT;

[0034] 3. During the call establishment process, the outgoing call from MRBT is called, and there is a detour in the call path
