摘要
呼叫模型是移动软交换设计的核心。在分析了现有移动软交换呼叫模型的基础上,提出了一种基于分布式的MSC-Server呼叫模型。该模型针对移动台发起前向承载建立呼叫控制流程的实现及路由的选择,实现了呼叫控制和媒体承载、业务逻辑和呼叫控制的分离,并支持多协议的接入,使得呼叫控制独立于底层承载协议,实现了移动软交换中移动性呼叫控制的设计要求。
Call model is the core in mobile softswitch design. On the basis of analyzing existing mobile sofiswitch call model a distributed MSC- Server call model is put forward. This model realized mobile station initiate the forward direction bearer establishment call control flow and route selection. This call-controlling model realizes the separation of call control and medium bearer, and the separation of service logic and call control, and it allows the accessing of multi-protocols, making call control indepent of underlying bearer protocols, and thus meeting the needs of the call control in mobile softswitch.
