Abstract:
1. A simulation method of a mobile communication system which has a first machine for simulating a base station controller, a second machine for simulating a base station, and multiple third machines, each simulating a mobile station associated with the corresponding base station, the first, second, and third machines being coupled together by a local area network (LAN), each of the third machines having an upper adaptation layer, a control entity, a service entity, an event generator, a pseudo driver, a network translation program, and a database, the upper adaptation layer being interfaced with an upper layer mobile communication protocol, the control entity being commanded by the upper layer mobile communication protocol for setting communication channels and associated physical layer measurement, the service entity providing services to the upper layer mobile communication protocol, the event generator generating simulation events, the method comprising: (a) after resetting one of the simulated mobile stations, commanding the mobile station to enter into an initialization state for fetching a dynamic Internet Protocol (IP) address from the simulation base station controller; (b) after the simulated mobile station obtains the dynamic IP address, determining whether there exists a simulated base station by receiving a broadcasting packet of the simulated base station; (c) if the simulated base station exists, commanding the simulated mobile station to request the simulated base station controller to obtain a dynamic IP address controlled by the simulated base station and establish an associated channel; (d) commanding the simulated mobile station to perform a certification procedure on the simulated base station via the channel; and (e) if the certification procedure is successful, commanding the simulated mobile station to enter into a link state for simulating mobile communication.
