Information Search Method Between Network Element In Wireless Intelligent Network

摘要

PURPOSE: A method for retrieving information between network elements in a mobile intelligent network is provided to obtain information corresponding to a specific condition associated with intelligent network call process by providing a retrieval operation including the specific condition for obtaining necessary information during an intelligent network service logic procedure. CONSTITUTION: If a termination SSP(Service Switching Point,24) is different from an origination SSP(21), a routing request message is transmitted to the termination SSP(24) for receiving a TLDN(Temporary Local Directory Number,S26). The termination SSP(24) assigns the TLDN for setting a routing with the origination SSP(21) and returns a routing response message to an HLR(Home Location Register,22,S27). The HLR(22) includes the TLDN received from the termination SSP(24) in a service data access element list parameter and transmits the service data access element list parameter to an SCP(Service Control Point,23,S28). The SCP(23) includes the TLDN received from the HLR(22) in a terminal list parameter of an analysis response message and returns the terminal list parameter of the analysis response message to the origination SSP(21,S29). The SSP(21) converts a call into a VMS(Voice Message System,25) of a termination-side mobile subscriber through the termination SSP(24,S30,S31) for providing a call conversation service to the VMS(25).
