Ringing tone service realization method based on IP and ringing tone media server

Abstract

The invention provides a ringing tone service realization method based on an IP and a ringing tone media server. The method comprises the steps of carrying out first media negotiation with a signaling server and obtaining the information of a media gateway, recording the information of the media gateway, carrying out second media negotiation with the media gateway according to the recorded information of the media gateway, receiving a ringing tone playing message carrying ringing tone file path information sent by a service logic server after the second media negotiation is completed, recording the ringing tone file path information, obtaining a ringing tone file which is encoded as a media format needed by ringing tone calling in advance based on the IP according to the recorded ringing tone file path information, and sending the ringing tone file to the media gateway which sends the file to a calling terminal. According to the ringing tone service realization method based on the IP and the ringing tone media server, the performance of the ringing tone media server can be raised, the system complexity is reduced, the utilization rate of memory is raised, the memory copy is reduced, and the sound jitter is reduced.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to an IP-based color ring service implementation method and a color ring media server. Background technique [0002] The color ring tone is a customized audio / video provided by the called user to the calling user during the call establishment process to replace the ordinary ring back tone service. In the core network based on the Internet Protocol (IP for short), the CRBT media server cooperates with signaling equipment and service processing equipment to complete the CRBT service. [0003] In the prior art, the IP-based CRBT media server is mainly realized by real-time ring tone coding. When the CRBT media server sends a voice packet to the media gateway (core network device), it first reads the logarithmic pulse code modulation sampling standard G711 format voice packet, encodes the G711 format voice packet into the media format required by the IP CRBT in real time, and then se...
