Research On CORBA-based Distributed IN And Implementation Of IN/CORBA Gateway

This paper proposes the architecture of CORBA-based(Common Object Request Broker Architecture ) distributed Intelligent Network, designs the Call Control layer in the architecture, and presents the intelligent service flow. Also, the implementation of the IN/CORBA gateway required by the connection between the distributed IN and the traditional PSTN is given. INAP(Intelligent Network Application Protocol) describing in ASN. 1 is translated into EDL(Interface Definition Language), i.e. Specification Translation. Moreover, a group of CORE A objects are defined in the gateway. Through the interacting among these objects, the mechanism of message transmission in INAP is converted to the mechanism of method calling in CORBA, i.e. Interaction Translation. The analyse of how to improve the performance of the gateway is also given.
