Asynchronous delivery mode How to restart by signal from virtual channel switching system

摘要

1. TECHNICAL FIELD OF THE INVENTION The present invention relates to an asynchronous delivery mode re-start method in a virtual channel switching system;2. Technical Problems to be Solved by the Invention: There was no way to release resources that are occupied by a virtual channel when a failure occurs while the call release is not normally performed or a call is being performed.;3. Summary of the Solution of the Invention: Upon receipt of the re-start request, the subscriber station releases the UNI link resources, releases the switch link resources, releases the UNI bandwidth resources, It is possible to increase the efficiency of resource management by releasing the connection from the matching module controller (SIMC) and transmitting the call release request signal to the other party, that is, the partner station to which the call is connected. Further, This can increase the success rate of the call connection and improve the performance of the exchange.;4. Important Uses of the Invention: Asynchronous delivery mode Used as a signal-based restart method in a virtual channel switching system.
