PURPOSE: A method for routing messages between V5.2 layer3 processing apparatus and a call control processor are provided to supply a call process service to a wireless fixed subscriber in a wire switching system by interworking with a WLL system. CONSTITUTION: A routing path is set up by exchanging one-to-one processor ID and a process ID between V5.2 L3 processor and a routing process, and exchanging one-to-N process ID between the routing process and a call processing main process(ST11-ST16). If receiving a message requesting an origination, the V5.2 L3 processor transmits the message having a port number to the routing process by using the set routing path, the routing process performs message interface function by finding a line number corresponding to the port number and transmits the message to the call processing main process(ST17-ST21). If receiving the message, the call processing main process generates a call process child process, stores a routing process ID and own process ID in a call information table, and generates a confirmation message for origination request having a call information table pointer and the line number(ST22-ST26). If receiving a message requesting destination, the call processing main process generates the call process child process and transmits the message having the call information table pointer and the line number to the routing process by using the stored routing process ID(ST27-ST28). The routing process receiving the confirmation message for origination request or the message requesting destination performs message interface function by using the call information pointer and the line number, and transmits the message to the V5.2 L3 processor(ST29-ST32).
