Abstract:
An interworking method of a telecommunication management network (TMN) manager system and agent systems, said method comprising the steps of:(a) creating subscriber information for exchanges managed by said TMN manager system and connection information between said exchanges so as to build up a database;(b) receiving a permanent virtual connection request from said TMN operator, retrieving said database with originating/receiving subscriber numbers so as to determine an originating exchange and a terminating exchange, and then determining whether said originating exchange is the same as said terminating exchange;(c) sending a request to an agent system which manages a corresponding exchange for setup of a virtual connection if said originating exchange is the same as said terminating exchange, receiving the result of said connection, and transferring the result to said TMN operator;(d) sending a request to an originating agent system which manages said originating exchange for setup of said virtual connection if said originating exchange is different from said terminating exchange, receiving a response, retrieving link connection numbers between said originating exchange and said terminating exchange in said database with a receiving link number so as to find an exchange connected to a corresponding link and its link number, and then determining whether the found exchange is a terminating exchange;(e) sending a request to a receiving agent system for setup of said virtual connection if the found exchange is said terminating exchange, receiving a response, and intergrating and transferring a result of the response and information to said TMN operator; and(f) sending a request to a corresponding relay agent system if the found exchange is a transit exchange, receiving a response and repeating the steps of finding the exchange and its link number as in said step (d).
