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, and the invitation message carries a video call sign; the CRBT application server triggers media negotiation to the playback device, And send the invitation message carrying the media of the calling party to the softswitch network; the softswitch network converts the invitation message carrying the media of the calling party into an initial address message and sends it to the called party for media negotiation. The softswitch network receives the feedback of the called party through the mobile switching center, converts the feedback into a ringing message and sends it to the CRBT application server after carrying the called party's media; the CRBT application server sends the ringing message to the softswitch network, And notify described sound-playing equipment...

Abstract

The invention discloses a method for realizing video polyphonic ringtone service, a device thereof and a system thereof, belonging to the field of communication. The method comprises the steps: a soft switch network (SS) receives call by a mobile switching center, converts the call into an invite message, and sends the invite message to a polyphonic ringtone AS, wherein the invite message comprises a video call mark; and the polyphonic ringtone AS triggers a media negotiation to sound reproduction equipment, and sends an invite message which comprises calling party media to the SS; and the soft SS converts the invite message which comprises the calling party media into an initial address message, and sends the initial address message to a called party to have the media negotiation. The SSreceives the feedback of the called party by the mobile switching center, converts the feedback into a 180 message, and sends the message which comprises the called party media to the polyphonic ringtone AS; the polyphonic ringtone AS sends the 180 message to the SS, and informs the sound reproduction equipment to reproduce sound to the calling party; and the SS converts the 180 message into a receive confirming message and informs the calling party to receive the sound reproduction from the called party. The invention can realize the requirement of the video polyphonic ringtone for 3G MSC network users.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and system for realizing the video ring back tone service. Background technique [0002] The broadband video ring back tone service is a system based on the Session Initiation Protocol (SIP) and integrates data, voice, and Softswitch (Software Switch, SS) networks. It is a real-time service on 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 (Third Generation, 3G). However, users under the 3G MSC network do not yet support video ring back tones. Therefore, a technical solution to this problem is urg...
