摘要
首先介绍了基于IMS(IP Multimedia Subsystem,IP多媒体子系统)实现多媒体彩铃(Multimedia Ring Back Tone,MRBT)业务的工作原理,在分析了该方案优缺点后,提出了一种快速、经济的基于独立智能外设(Independent Intelligent Peripheral,IIP)的由控制节点CN通过VIPS(Virtual Integrated Programmable Switch,虚拟综合可编程交换机)控制MSIP(MultiMedia Server Intellectual Processor,多媒体服务器智能处理板)板卡实现多媒体彩铃业务的方案,分析了此方案的系统结构、内部信令的交互流程,最后列出了具体的功能模块修改点。
This paper first introduces the realizing principle of Multimedia Ring Back Tone(MRBT) service based on IP Multimedia Subsystem(IMS).After analyzing the advantages and disadvantages of that implementation,it presents a faster and more economical implementation scheme of MRBT service based on Independent Intelligent Peripheral(IIP) platform.In the new schema,CN(Control Node) controls the MSIP(MultiMedia Server Intellectual Processor) board to implement the MRBT service via VIPS(Virtual Integrated Programmable Switch) proxy application.The system structure and the internal signal interactive process are also presented.Finally,it gives the brief implementation mechanism for improvement of IIP.
