A Novel Frequency Shift Keyboard Call Simulation Method

Abstract

Hardware simulation pager usually is very expensive and can only simulate 16 subscriber line or 32 subscriber line. And in FMC (fixed and mobile convergence) system, FSK (frequency shift keying) is used to transfer information between home gateway and the program controlled switch. In this paper, a novel FSK call simulation method to design a pager is proposed to use software to simulate the interaction of FSK between home gateway and the program controlled switch during a normal call procedure, and to meet the demand of the performance and capacity testing of the FMC system. The FSK call simulation includes a back-end management system and a foreground simulation system. And the foreground simulation system consists of MP (module process) module, SP (subscriber process) module, ASIG (analog signal) module, and so on. The MP is the module’s main control process, and it will control the logic of call, and transfer simulation control information between back-end management system and the other modules in the foreground. The SP is the module, in which the FSK call simulation process lying in. And ASIG module can send FSK signal to home gateway, and receive FSK signal from home gateway. The novel FSK call simulation method can test the performance and capacity of the FMC platform by the means of software, and lower the expense of testing.
