 To solve the problem of the channel and resource waste and the experience of the calling terminal, the method for processing the IMS domain CRBT service is provided in the embodiment of the present invention. The specific processing flow is as shown in FIG.

 Step 101: Receive notification information sent by the called terminal during a process in which the calling terminal initiates a call to the called terminal.

 Step 102: Select, according to a mapping relationship between the identifier of the established CRBT service and the notification information sent by the called terminal, the identifier of the CRBT service corresponding to the notification information sent by the called terminal.

 Step 103: Play the CRBT service corresponding to the identifier of the selected CRBT service to the calling terminal. The CRBT service signed by the user of the called terminal may be one or multiple, depending on the actual situation. For example, the user of the called terminal may select multiple songs or ring tones as the ring tones, or may record certain specific sound segments according to the wishes of the user of the called terminal, or select one or more images as the color ring tones, as well as according to the The user of the terminal is willing to record certain image segments as ring tones. When the CRBT service signed by the user of the called terminal is more than one, each CRBT service may correspond to different notification information. After the called terminal receives the call initiated by the calling terminal, the user of the called terminal selects a CRBT service, and the called terminal sends corresponding notification information, so as to select one CRBT service from the plurality of CRBT services to be played to the calling terminal. The user is selected because the notification information of the called terminal is selected by the identifier of the CRBT service. Therefore, after receiving the notification information sent by the called terminal, the notification is sent according to the identifier of the established CRBT service and the called terminal. The mapping relationship between the notification information is selected from the identifier of the CRBT service signed by the user of the called terminal.

According to an embodiment of the present invention, the user of the called terminal can according to his own wishes and/or the current field. The scene is selected for the CRBT service. For example, the user of the called terminal is currently in a meeting or is currently driving or other scenes. You can select the CRBT service according to the corresponding scene. "I am in a meeting, contact later" or "I am in a meeting, later Contact " or other ring tones.

 Referring to the process shown in FIG. 1 , in step 102, a mapping relationship is established between the identifier of the CRBT service and the notification information sent by the called terminal. The notification information may be button information, touch point information, or other notifications. For example, the ringtone service corresponding to button 1 is "I am in a meeting, later contact", and the ringtone service corresponding to button 2 is "I am in a meeting, contact later", and so on.

 Step 202: Obtain a second media identifier of the called terminal, and send the second media identifier to the media server, and receive a second negotiation media identifier that is responded by the media server.

Step 203: Confirm the media negotiation result and the media file path of the CRBT service played to the calling terminal according to the first negotiation media identifier and the second negotiation media identifier, and send the media file path Give the media server.

 In the implementation, the step 201 can be performed as follows: The CRBT service server queries the multimedia ring back tone file to be played in the database, and sends an INVITE message to the media server, where the media identifier sdpA of the calling terminal starts, and the calling terminal and the media start. Media negotiation between servers; the media server returns a 200 OK message (response to the INVITE message) to the CRBT service server, which has the negotiation media identifier sdpAC corresponding to the calling terminal; the CRBT service server sends an ACK (response to the 200 OK message) ) Message to the media server. The implementation of step 202 is similar to step 201. The CRBT service server sends a trigger INFO message to the media server, where the media file path is sent to the calling terminal to play the CRBT service. The media server starts to play the CRBT service according to the media negotiation result and the media file path, and the user of the calling terminal starts to listen to the CRBT. business. After playing, the media server returns a 200 OK message (response to the INFO message) to the CRBT service server.
