Method for nesting of video phone services, and system thereof

Abstract

The present invention discloses a method for nesting of video phone services and a system thereof. The method comprises the steps as follows: a calling UE (User Terminal) initiates a video phone call; a calling MSC-S (Mobile Switch Center Server) receives the video phone call; if the calling MSC-S discovers that a fallback occurs to a called UE, the calling MSC-S routes the video phone call to a VP+AS (Video Phone Enhanced Application Server); and the VP+AS establishes a video phone session with the calling UE, and establishes a voice phone session with the called UE. Or the method comprises the steps as follows: the calling UE initiates a video phone call; the calling MSC-S receives the video phone call; if the calling MSC-S discovers that the called UE supports a multimedia ring back tone service, the calling MSC-S routes the video phone call to a MRBT (Multimedia Ring Back Tone) platform; the MRBT platform establishes the video phone session with the calling UE, and plays the multimedia ring back tone customized by the called UE to the calling UE; and after the called UE responses, if the MRBT platform discovers that the called UE supports a VP+ video substitution service, the MRBT platform establishes the video phone session with the VP+AS. The method as well as the system in the present invention realizes nesting of the video phone services.

Description

technical field [0001] The invention relates to the technical field of videophone, in particular to a videophone service nesting method and system. Background technique [0002] The multimedia ring back tone service of videophone is a videophone service in time division (TD, Time Division) circuit domain, which is ordered by the called user. While ringing, the caller is provided with a beautiful and pleasing multimedia video instead of the ordinary ring back tone. After the user applies for the multimedia ring back tone service, he can set the content of the multimedia ring back tone by himself, which is used to play the customized multimedia video for the calling party when the user rings the called ring. [0003] The videophone enhancement (VP+) service is improved for the fallback of the videophone, so as to ensure that the calling user can experience the videophone service as much as possible. When the fallback is caused by the called side (including the network and th...

AI Technical Summary

Problems solved by technology

At present, there are many value-added video services for videophones. The existing technical solutions cannot support the nesting and calling of video services. As a result, users cannot activate other video services after activating one type of video services.

For example: after the called user subscribes to the multimedia ring back tone service, he cannot subscribe to the VP+ service any more. In this way, when the called side falls back, the calling party and the called party can only conduct voice calls; at the same time, the called party cannot Show alternate video to caller
