Embodiment Construction

[0044] The core idea of ​​the present invention is: the softswitch network receives the call through the mobile switching center, converts the call into an invitation message and sends it to the CRBT application server, the invitation message carries the video call flag; the CRBT application server triggers media negotiation to the playback device, And send an invitation message carrying the calling party's media to the softswitch network; the softswitch network converts the invitation message carrying the calling party's media into an initial address message and then sends it to the called party for media negotiation. The softswitch network receives the called party’s feedback through the mobile switching center, converts the feedback into a ringing message and carries the called party’s media and sends it to the CRBT application server; the CRBT application server sends the ringing message to the softswitch network, And notify the playback device to play the calling party; the...

Abstract

The present invention provides a method, apparatus and system for implementing video color ring back tone service. In the scheme of the present invention, a Soft Switch (SS) network receives a call through a Mobile Switching Center (MSC), and triggers the call to a color ring back tone Application Server (AS); the color ring back tone AS triggers a media negotiation to a Universal Streaming Server (USS); the color ring back tone AS, the SS network, and the MSC complete the media negotiation with the called party and the calling party together; the color ring back tone AS notifies said USS to play the video color ring back tone for the calling party, and notifies the calling party, through the SS network, to receive the video color ring back tone, thus satisfying the requirement of the video color ring back tone for the user under the MSC in the third generation (3G) communication system, being able to provide better color ring back tone service, and greatly facilitating the development of the color ring back tone service.

Description

Technical field [0001] The invention relates to the field of communications, and in particular to a method, device and system for realizing video color ring back tone service. Background technique [0002] The broadband video ring back tone service is a system based on the Session Initiation Protocol (SIP), which integrates data, voice, and soft switch (Software Switch, SS) networks. It is a real-time service in the packet switching domain. The flexible service capability of IP is rooted in the communication system, which greatly improves the support capability of the CRBT service. [0003] The SS network video ring back tone service is currently a relatively mature and stable service, and it is also applied in the existing network. The SS core network can communicate with the Mobile Switching Center (MSC) in the third generation (3G). However, users under the 3G MSC network do not yet support video ring back tones. Therefore, a technical solution to solve this problem is urgently...
