Zhihua Wang · Radio Engineering · 2010
First,the basic techniques for developing the call processing software are introduced.The software architecture based on Vxworks and the real-time call processing software system are presented.Finite State Machine(FSM)and software framework are studied.Then hierarchical call processing software framework is elicited and the main functions of call control module are introduced.The call control entity is abstracted,the design of parameters of the call control entity is described,and the call control instance is given.At last,the test of call processing software is conducted and the analysis of test results is given.
