摘要：
This article analyses the advantages of disassembled gateway based on its functions, and introduces the processing of signaling and media streams. Moreover, a function-separated gateway is designed and implemented, which consists of media gateway controller and media gateway. So we propose originally the Stochastic Petri-net model of media gateway controller, and educe the mathematical relationship between load of gateway controller and other factors such as rate of call initialing, delay of call setup, and delay of call release. Lastly, we summarize some important factors which affect performances of gateway, and make a conclusion that decreasing the delay of call setup will improve Media gateway controller efficiency.
