为拓展现有智能网呼叫模型的功能以支持新增业务,借鉴移动核心网架构,引入移动网关局功能,按照有限状态机思想设计呼叫事件驱动,明确呼叫路由选择功能。对改进后的模型在相关呼叫协议下进行呼叫话务排队系统仿真,结果表明,在保证呼叫质量的前提下,呼叫丢包率下降0.02%,能对新增移动业务和具有新特性的传统业务提供良好支持。
In order to extend the functions of the existing intelligent network call model to support new services, learn from the mobile core network architecture, introduce the functions of the mobile gateway office and design the call event-driven according to the idea of the finite state machine to clarify the call routing function. The simulation results show that under the precondition of guaranteeing the call quality, the drop probability of call drops by 0.02%, which can improve the performance of new mobile services and traditional services with new features Provide good support.
