Mobile radio communications device for closed subscriber group management
First Claim
1. A mobile radio communications device communications system, the mobile radio communications device comprising:
- a non-access-stratum layer (NAS) and an access-stratum layer (AS);
at least one processor configured to retrieve, from a Universal Subscriber Identity Module (USIM), at least one of an Allowed closed subscriber group (CSG) list and an Operator CSG list, and to indicate, to a user, available closed subscriber groups to allow the user to make a manual selection of an available closed subscriber group; and
storage configured to store closed subscriber group information, the stored closed subscriber group information including information configured as a whitelist of closed subscriber group identities,wherein the whitelist is provided by the NAS to the AS,wherein the NAS is configured to update the contents of the CSG whitelist when the contents of the CSG whitelist have changed, andwherein when an attempt is made to register in a cell of a closed subscriber group chosen by the user, and the registration attempt is accepted, the identity of the closed subscriber group is added to the Allowed CSG list, unless an identity is already present in the list.

Abstract
The present invention provides for a mobile radio communications device, and related method of operation, arranged for closed subscriber group selection and for the storage of closed subscriber group information in the device, the stored information including information configured as a whitelist of closed subscriber group identities delivered between non-access-stratum layer and access-stratum layer within the device, and the device being further arranged to remove a previous user-selected closed subscriber group identity from the whitelist responsive to the device connecting to a cell is different from that identified by the previous user-selected closed subscriber group identity, and which different cell can comprise for example a non-CSG cell.

13. A method of managing closed subscriber group selection performed by a mobile radio communications device, the method comprising the steps of:
-
retrieving, from a Universal Subscriber Identity Module (USIM), at least one of an Allowed closed subscriber group (CSG) list and an Operator CSG list, and indicating, to a user, available closed subscriber group to allow the user to make a manual selection of an available closed subscriber group; storing closed subscriber group information configured as a whitelist of closed subscriber group identities; providing the whitelist from a non-access stratum layer (NAS) to an access stratum layer (AS) within the mobile radio communications device; and updating, in the NAS, the contents of the CSG whitelist when the contents of the CSG whitelist have changed, wherein when an attempt is made to register in a cell of a closed subscriber group chosen by the user, and the registration attempt is accepted, the identity of the closed subscriber group is added to the Allowed CSG list, unless an identity is already present in the list. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
