Abstract: PURPOSE: A call setup control method in an ATM-based mobile communication system is provided to offer mobile communication subscribers a high-quality mobile communication service by detecting and preventing a call setup failure with every BTS(Base Transceiver Subsystem) within a service area of a BSC(Base Station Controller). CONSTITUTION: When a new call setup request is generated from a mobile terminal(S20), an ATM network control processor transmits a call setup request message to an ATM exchange processor through a main connection unit(S21) and waits for receiving a response message to the call setup request message(S22). If the ATM network control processor fails to receive the response message from the ATM exchange processor until the limit number of times of re-transmissions exceeds, the ATM network control processor determines that there is an error in the main connection unit(S23,S24). The ATM network control processor switches a communication channel with the ATM exchange processor to an auxiliary connection unit and transmits the call setup request message to the ATM exchange processor through the auxiliary connection unit(S25).
