Embodiment 1

[0059] This embodiment provides a method for calling a multimedia ring tone service, such as figure 1 As shown, the call method includes the following steps:

[0060] 101. The calling terminal initiates a call request to the call control entity, and the call request carries terminal capability information and / or multimedia ring tone service capability information; the call control entity in this embodiment may be a call server ( Call Server) or a call control center server (MSC Server); in the IP Multimedia Subsystem (IMS), it may be a Call Session Control Function (CSCF, Call Session Control Function).

[0061] This embodiment provides a control method for a multimedia ring tone service, such as figure 2 As shown, the control method includes the following steps:

[0062] 201. Receive a call request initiated by a calling terminal, where the call request carries capability information of the calling terminal.

[0063] 202. Determine whether the calling terminal supports th...

Embodiment 2

[0079] The application scenario of this embodiment is a CS domain network using a Call Server, where the calling terminal accesses the communication network through the Call Server, and the calling terminal connects to the Call Server through a gateway. In this embodiment, the call control entity is implemented by Call Server, and AS-FE (application support function entity) and MRP-FE (media resource processing entity) connected with CallServer are set; the multimedia ring tone in this embodiment Services include multimedia ring tone, multimedia ring tone and multimedia color image services.

[0080] like Figure 9 As shown, the control method of the multimedia ring tone service in the present embodiment includes the following steps:

[0081] 901. In order to initiate a multimedia call to the called terminal, the calling terminal sends a request B message (that is, a call request) to the Call Server, and the request B message includes terminal capability information and / or mu...

Embodiment 3

[0107] This example is an embodiment of carrying the terminal capability of the multimedia ring tone through the CS (circuit) videophone. In this solution, the calling terminal accesses the PLMN (Public Land Mobile Network) core network through MSC Server A, wherein MSC Server A completes the function of the call control entity, and completes the multimedia ring tone service through the multimedia ring back tone platform to realize the media resource The function of the processing entity; the multimedia ring tone service in this embodiment includes multimedia ring tone, multimedia ring tone and multimedia color image services.

[0108] like Figure 10 As shown, the control method of the multimedia ring tone service in the present embodiment includes the following steps:

[0109] 1001. In order to initiate a multimedia call to the called terminal, the calling terminal sends a setup (SETUP) message to MSC Server A, and the message carries terminal capability information and sup...

Abstract

The invention discloses a method, a device and a system for calling and controlling multimedia ringtone service, relates to the multimedia ringtone service, and solves the problem that establishment of a normal voice channel is affected when a terminal does not have early-stage media negotiating capability. The embodiment of the invention enables a calling control entity or an application supportfunctional entity to determine whether a calling terminal supports the multimedia ringtone service or not by carrying terminal capability information in a calling request initiated by the calling terminal; if the calling terminal does not support the multimedia ringtone service, the calling terminal does not have the early-stage media negotiating capability, so a request for establishing an early-stage media channel between the calling terminal and a media resource processing entity does not need to be initiated. The embodiment of the invention is mainly used for the multimedia ringtone service system.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method and device for calling and controlling multimedia ring tone service used in communication, and a system using the control method. Background technique [0002] During the establishment of a voice call session, after the calling terminal finishes dialing, a voice channel is established between the calling terminal and the switch, and the switch instructs the called terminal to ring; The switch sends a ring back tone to the calling terminal, or the calling terminal itself plays the ring back tone. When the called terminal goes off-hook, a voice channel is established between the called terminal and the switch, so that the calling terminal and the called terminal can pass through the voice channel between the calling terminal and the switch, and between the called terminal and the switch. the voice channel to make a call. In order to effectively utilize the voice chan...
