Abstract:
A frame relay interworking service control method using a permanent virtual connection comprising:a frame relay subscriber information registration process of verifying a time slot usage state upon receiving a frame relay subscriber registration requirement through a system operator interface, computing an access rate, setting a registered subscriber information to FCIM, and outputting a normal/abnormal result to a frame relay subscriber registration process to a system console;a frame relay subscriber connection registration process of determining whether CIR (Committed Information Rate) for a connection registration in the subscriber is permitted or not upon receiving the frame relay subscriber registration requirement through the system operator interface, generating ATM connection identifier (VPI/VCI) corresponded to the frame relay connection, computing PCR (Peak Cell Rate) corresponded to CIR, Bc (Committed Burst Size), Be (Excess Burst Size) for translating a frame relay traffic and ATM traffic, setting a registered frame relay connection information to FCIM (Frame Relay Interface Controller), outputting a normal/abnormal result to a frame relay connection registration process to a system console; anda PVC interworking process of retrieving a frame relay connection information table by means of the VPI/VCI appointed when interworking PVC (Permanent Virtual Circuit), verifying a compatibility of the interworking required PVC parameter and the frame relay connection, interworking a connection between the registered frame relay subscribers or a connection between the frame relay subscriber and ATM subscriber.
