PURPOSE: A control method for duplexing of a matching system for providing a V5.2 protocol of a wireless switching system is provided to prevent an occurrence of blocked or call-cuts to enhance a stability of a system by searching messages received from a subscriber network or a TCP(Telephony Control Processor) during a recovery process to previously process searched messages and normally processing received after processing searched messages. CONSTITUTION: A matching system(1000) has a TCP(100) for providing a call process, first and second MPPAs(Multiprotocol Processor Board Assemblies)(200,210) for providing a V5.2 L3 function, and 8 MPLAs(Multiprotocol Processor Line Assemblies)(300,310) for providing V5.2 L1 and L2 functions and a matching function to a subscriber network. The TCP(100) has a V5SC(V5.2 Subscriber Control)(110) for a call process and two V5SAs(V5.2 Subscriber Adaptations)(120) for matching the V5SC(110) and the V5.2 L3. The TCP(100) transmits call process and maintenance messages to MPPAs(200,210). MPPAs(200,210) receive data from the subscriber network and control MPLA(300,310). If a problem is occurred in one MPPA, the other normal MPPA processes all messages. |
