Method for setting application server by proxy server in soft switching system

The invention discloses a method for arranging proxy server of application server in soft exchange system, comprising: A, the application server sends the registering require to the proxy server which will form the register list of application server according to the information of requirement; B, the proxy server refreshes the register list and sends the requirement for inquiring source to the application server which will respond the requirement and send the information of source to the proxy server; C, the proxy server, according to the outside service requirement, utilizes the service key, the operational source condition of application server, the defined load control of application server and the equilibrium strategy of service requirement to realize the distribution of different service requirement to application server. The invention solves the problems of centralized loaded of the service of application server and the over-load control, to simplify the management of server and support convenience to the variable operations of application server.
