METHOD FOR CONTROLLING CALL DISTRIBUTION OF CONTROL STATION IN INTERNATIONAL MOBILE TELECOMMUNICATIONS-2000(IMT-2000)

摘要

PURPOSE: A method for controlling call distribution of a control station in an international mobile telecommunications-2000(IMT-2000), is provided to distribute call process for processing originating/incoming calls of a mobile terminal to every processor inside the control station, thereby reducing a call saturation state and efficiently using a selector resource of a control station. CONSTITUTION: A call message is received to a base station charging process from a corresponding access channel, and the message is transmitted to a No.7 signal connector to set up a No.7 signal link. A mobile switching center(MSC) approves a mobile terminal, and transmits information necessary for the corresponding wireless call to the No.7 signal connector. A sub table established in the No.7 signal connector is updated, and the information received from the MSC and the sub table are transmitted to the base station charging process. The base station charging process allocates channel elements(CEs) of a corresponding to base transceiver station(BTS) in the base station charging process and analyzes the sub table to confirm whether a present processor is in an overload state and generates selector charging process in a selected processor. The selector charging process requests the change of the firstly set No.7 link and allocates selectors. A selector receives a control signal transmitted from the mobile terminal through the selected CE, and the control signal is transmitted to a selector processor.
