Title:
MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/052843
Kind Code:
A1
Abstract:
A CSG (Closed Subscriber Group cell) permits a subscriber to use the cell. In order to receive a service of the CSG cell, a CSG-ID should be reported to a mobile terminal. However, if no radio wave from a non-CSG cell reaches, no service can be obtained. A mobile communication system includes a base station arranged in a CSG cell and a base station arranged in a non-CSG cell and accesses the CSG cell by using a CSG-ID issued when use of the CSG cell is permitted. The base station arranged in the CSG cell references an identifier of the mobile terminal reported and transmits a tracking area update request from a mobile terminal to a core network. The core network checks whether the mobile terminal is permitted to use the CSG cell. If yes, the core network transmit a signal permitting allocation of a radio resource to the mobile terminal and a CSG-ID. The mobile terminal accesses the CSG cell by using the CSG-ID.
