| 摘 要： | 通话回放(TRPB)业务是在用户通话过程中可以动态触发并进行通话录音,事后通过拨打特殊号码听取录音回放的一种增值业务.基于IMS网络的体系结构以及通话回放业务的业务特征,本文提出了一种利用通话回放业务平台(TRPBSP)来实现通话回放业务的解决方案,包括实现方案、详细设计以及基于SIP消息的信令流程.同时,对业务特点进行分析并进行了总结.

| Abstract: | Talk record & play back service is a kind of value-added service, with which, the user can dynamically trigger the talk-record function during the process of phone call, and subsequently listen to the play-back of the record by dialing a special phone number. Based on the network architecture of IMS and the service characteristics of TRPB, a solution using the talk record & play back service platform to provide TRPB service is proposed. The article mainly interpretes realization scheme, detailed design and signalling flow based on session initiation protocol. Meanwhile, the analysis and summarization of TRPB service are given. |
