MOBILE COMMUNICATION SYSTEM, LOCATION REGISTER METHOD AND CALL PROCESSING METHOD FOR IN-BOUND ROAMING SERVICE

摘要

PURPOSE: A mobile communication system for inbound roaming service, a location registration method thereof and a call processing method thereof are provided to offer the inbound roaming service to a prepaid subscriber by using service control point and gateway location register. CONSTITUTION: When a visited network has a different intelligent network message standard information from a home network, a GLR(Gateway Location Register)(130) inquires the HLR(Home Location Register) of the home network according to a location registration request of an inbound roaming terminal. The GLR acquires service type information of the inbound roaming terminal including the intelligent network message standard information of the home network. A SCP(Service Control Point)(140) generates and stores an intelligent network subscriber information for the inbound roaming terminal using the service type information. A visited network MSC(Mobile Switching Center)(120) sets an intelligent network call processing for the inbound roaming terminal to the visited network SCP.
