    In order to develop mobile wireless call procedures, the designer is presented with a host of design alternatives. The problems range from having to support different patterns of user mobility to integrating the call generators and all functional entities that support call procedure. MobCall(Mobile Call Generator) designed in this paper can simulate call processing procedures considering of operation, environment, and call characteristics of the cell. In MobCall, the various functional entities such as the Mobile Station(MS), Base Station(BS), Mobile Switching Center(MSC), Home Location Register(HLR) and Visitor Location Register(VLR) and relative reference points in IS-41[1] have been implemented to simulate the procedure of location registration due to handset power on, mobile originating call, intra-MSC handoff and inter-MSC handoff. MobCall can be used to improve the function of HLR, VLR and the call procedure, and also to develop and test the efficiency of handoff mechanism.
