CALL PROCESSING METHOD FOR PROVIDING ADDITIONAL HOME ZONE SERVICE IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A call processing method for providing an additional home zone service in a mobile communication system is provided so that a user can receive a high quality mobile communication service by providing the additional home zone service. CONSTITUTION: A transmission side exchanger(101) manages a special location or region for a home zone service of a transmission subscriber. When the transmission subscriber transmits in the special location for the home zone service, the transmission side exchanger(101) provides the home zone service. When the transmission subscriber is a mobile subscriber, the transmission side exchanger(101) connects a call through a reception side exchanger(201). A transmission side visitor location register(102) is connected to the transmission side exchanger(101), for storing and managing information of the transmission subscriber. A transmission side home location register(103) stores location and routing information of the transmission subscriber. When a reception subscriber is a mobile subscriber, a reception side exchanger(201) manages a region of the reception subscriber. A reception side home location register(202) has the same function as the transmission side home location register(103). The reception side home location register(202) stores routing information of the reception subscriber, and processes a routing information request from the transmission side exchanger(101).
