In this paper, we designed and implemented a call processing protocol for PCS on the distributed cluster-based ATM network. For design of the call processing protocol, we set up a model for the distributed environment and the call processing procedure through object modeling of the system components and dynamic modeling of the signals between the system objects. We divided the system into the several logical blocks and defined the objects within each block and the signals transmitted among those objects. We also defined states of each object and state transitions caused by lots of signal exchange. We verified the correctness of the designed protocol by correcting the error and modified the protocol through the simulation. For the efficient implementation of the protocol, we use the OMT(Object Modeling Technique), SDL(Specification and Design Language) and MSC(Message Sequence Chart).
