BASE STATION CONTROLLER AND MOBILE TERMINAL
First Claim
1. A base station controller applied to a network that comprises a plurality of CSG cells, the base station controller comprising:
- an access permission information storing section having a CSG identification of a CSG cell that a mobile terminal is permitted to access stored therein with the identification associated with the mobile terminal;
a CSG cell information storing section having a physical cell ID corresponding to the CSG cell identification stored therein;
a location information receiving section for receiving information identifying a CSG cell in which the mobile terminal is located;
a mapping section that reads at least one CSG cell accessible to the mobile terminal from the access permission information storing section, reads, from the CSG cell information storing section, a physical cell ID of an adjacent CSG cell among the read CSG cells within a predetermined range of the CSG cell in which the mobile terminal is present, and generates an accessible physical cell ID list to the mobile terminal; and
a notification section for providing the mobile terminal with the accessible physical cell ID list.

Abstract
An HeNB-GW (120) is applied to a network that comprises a plurality of CSG cells, and comprises: an access-permitted CSG-ID list storing section (425) having a CSG identification of a CSG cell that a mobile terminal (140) is permitted to access stored therein; an HeNB information storing section having a PCI corresponding to the CSG cell identification stored therein; a location information receiving section (412) for receiving information identifying the location of the mobile terminal (140); a PCI mapping section (420) that reads at least one CSG cell accessible to the mobile terminal (140) from the access-permitted CSG-ID list storing section (425), reads, from the HeNB information storing section 430, a PCI of an adjacent CSG cell among the read CSG cells within a predetermined range of the CSG cell in which the mobile terminal (140) is present, and generates an accessible PCI list to the mobile terminal (140); and an HeNB managing section 410 for providing the mobile terminal (140) with the accessible PCI list. Therefore, a base station controller with which a mobile terminal can immediately be connected to a CSG cell that the mobile terminal is permitted to access may be provided.

12. A base station controlling method by a base station controller applied to a network that comprises a plurality of CSG cells, the method comprising:
-
receiving, by the base station controller, information identifying a CSG cell in which the mobile terminal is located; reading at least one CSG cell accessible to the mobile terminal from an access permission information storing section having a CSG identification of a CSG cell that a mobile terminal is permitted to access stored therein with the identification associated with the mobile terminal; reading, by the base station controller, a physical cell ID of an adjacent CSG cell among the read CSG cells within a predetermined range of the CSG cell in which the mobile terminal is present from a CSG cell information storing section having a physical cell ID corresponding to the CSG cell identification stored therein, and generating an accessible physical cell ID list to the mobile terminal; and providing the mobile terminal with the accessible physical cell ID list.
