A method of designing parameters of internal protocol message for processing UNI / NII call in asynchronous transfer mode virtual channel switch

摘要

The present invention relates to a parameter design method of an inner protocol message for processing a user network interface (UNI) / network node interface (NNI) call in an asynchronous transfer mode virtual channel (ATM) VC exchanger, In order to solve problems such as complexity of a processing program due to complexity of parameter mapping during interworking, difficulty of a test laboratory, deterioration in system processing performance, and the like, the present invention provides an intra protocol Is designed to be the same as the parameter of the UNI protocol message, and the parameter of the protocol for the relay call processing is designed to be the same as the parameter of the NNI protocol message, and the external matching protocol message parameter is used only locally The parameters are defined as system internal protocol parameters. Provide one way to prevent.;Accordingly, the present invention can achieve simplification of the processing program according to the simplicity of protocol and parameter mapping in the interworking between protocols in the switching system, easiness in testing, improvement in system processing performance, and the like.
