软交换呼叫模型的研究与设计

Research and Design of the Call Model in Softswitch

提出了一种适用于软交换特点的呼叫模型,该呼叫模型的设计借鉴并改进成熟的智能网呼叫模型,增强媒体控制能力,实现呼叫控制与媒体承载、业务逻辑与呼叫控制的分离。支持对多协议的接入,同时满足开放式业务的需求,具有较好的灵活性和扩展性。

It describes a call control model based on the softswitch architecture. The design refers to the IN's call control model, and enhances the ability of media control. This call control model realize the separation of call control and media control, and that of call control and services logic. The model that can allow the accessing of the multi-protocols can satisfy the need of opening-services, and have the more flexibility and expansibility.
