摘要:
The invention relates to an application server and a method. The application server comprises a resolver which reserves a subscriber number prefix for test target applications. The resolver associates an address of an application server with the prefix in a memory and resolves subscriber numbers containing the prefix into the address using the memory. A network element simulator listens to a port, which has a port number which is also used in communicating with the network element being simulated. A test target application communicates with the simulator instead of the network element being simulated via a protocol stack in the application server. An application layer binding is used to route incoming messages to the test target application.
