Problems solved by technology

[0004] Since the video CRBT platform is connected between the calling terminal switch and the called terminal switch, when the calling terminal and the called terminal establish a call initial connection, the communication link must be established through the video CRBT platform, resulting in the The high performance requirements of the video CRBT platform; at the same time, after the calling terminal and the called terminal are connected to the phone, that is, after the video CRBT is stopped, the voice path still passes through the video CRBT platform, resulting in a circuitous voice path, which will affect the performance of the video CRBT platform The requirements are very high, and in the case of heavy traffic, the performance of the video ring back tone platform cannot meet the requirements, resulting in the failure of the videophone call

Embodiment 1

[0025] The playing method of the video color ring tone realized based on the above-mentioned system, see Figure 4 It is the operation flowchart of embodiment 1, and the specific steps for realizing that the called terminal provides video ring back to the calling terminal during waiting for the called terminal to pick up and establish a videophone call are as follows:

[0026] Step 401: the calling terminal initiates a videophone call request to the called terminal switch to the called terminal switch through the calling terminal switch;

[0027] Step 402: the called terminal switch inquires the subscription information of the called terminal to the home location register (HLR) on the network side, whether the video ring back tone service is customized, and if the service is customized, step 403 is performed; if the service is not customized, then end;

[0028] Step 403: The called terminal switch sends the subscription information and status information of the called terminal...

Embodiment 2

[0051] In this embodiment, the user's subscription information is stored in the local database of the video ring back tone platform. process, see Figure 6 , is the specific operation flowchart of Embodiment 2 of the present invention:

[0052] Step 601: the calling terminal initiates a videophone call request to the called terminal switch through the calling terminal switch;

[0053] Step 602: The called terminal switch sends the status information of the called terminal to the calling terminal switch; at the same time, the calling terminal switch returns a ringing signaling to the calling terminal, indicating that the called terminal is idle;

[0054] Step 603: the calling terminal switch initiates a request message to play the video ring back tone to the video ring back ring platform;

[0055] Step 604: The video CRBT platform queries the user subscription information stored in the platform database, whether the video CRBT service is customized, if the service is customiz...

Abstract

This invention relates to a method for playing video coloring ring back tone (CRBT), which contains the calling terminal sending called terminal request to called terminal exchanger which sending the idle state information of called terminal to calling terminal exchanger, at same time the calling terminal exchanger sending back ring signaling to calling terminal, when said called terminal configured video coloring ring back tone service the calling terminal exchanger sending play request to video coloring ring back tone platform which playing coloring ring back tone to calling terminal according to obtained called terminal signed contract information. Said invention has advantages of saving relay resource and reasonable network structure.

Description

technical field [0001] The present invention relates to a method for playing video color ring back, especially a method for playing video color ring back on the calling video phone when the calling video phone initiates a call service in a 3G network while the called phone rings. ; Belongs to the field of mobile communication data business. Background technique [0002] With the development of communication technology and the use of 3G networks, more and more value-added services will be realized. The video ring back tone service is a specific value-added service that combines the videophone service and the color ring back tone service on the 3G network. When a videophone user makes a videophone call, he can watch a gorgeous video picture customized by the called terminal user in the 3G circuit domain videophone service. [0003] The existing video phone video ring back tone service is realized by adopting a bridging scheme, that is, the ring back tone platform is bridged b...
