智能网会议业务的呼叫模型

Call Modeling for Supporting Conference Call Service

根据桌面电话会议模型，提出新的呼叫模型和基本呼叫状态模型。新的呼叫模型支持多用户连接业务，提供统一的基本呼叫状态模型，可简化系统软件设计。在此基础上，描述了会议业务中的呼叫建立、新成员加入和发言权转移等过程的呼叫处理。电话会议业务是在北京邮电大学８６３智能网项目研究成果ＣＩＮ－０２系统上设计实现的。

Intelligent network is developed on the basis of POTS' service. Its call modeling ( CM ) , which is based on the separated management of originating basic call state model (O-BC- SM ) and terminating BCSM ( T-BCSM ) , does not support conference call service (CCS ) . The new CM and BCSM are proposed to realize CCS. The proposed CM has features as follows : ( 1 ) a new BCSM resulted from the unification of O-BCSM and T-BCSM ; ( 2 ) The reduction of com- plexity of software in SCF . Some service requests proccessings are described on the basis of new CM. CCS is realized on the basis of CIN-02 system. CIN-02 system is the product of the research of national 863 IN project.
