Mobile radio communications device for closed subscriber group management

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.

What is claimed is: 
     
         1 . A method performed by a mobile radio communications device, the method comprising:
 storing an allowed closed group list which the mobile radio communications device is allowed to access;   providing, from a non-access stratum layer (NAS) to an access stratum layer (AS), an updated content of information including the allowed closed group list which has been changed;   indicating, to a user, one closed group identifier; and   initiating a registration on a network after a manual closed group selection.   
     
     
         2 . A mobile radio communications device comprising:
 a non-access stratum layer (NAS) and an access stratum layer (AS);   wherein the mobile radio communications device is configured to:
 store an allowed closed group list which the mobile radio communications device is allowed to access; 
 provide, from the non-access stratum layer (NAS) to the access stratum layer (AS), an updated content of information including the allowed closed group list which has been changed; 
 indicate, to a user, one closed group identifier; and 
 initiate a registration on a network after a manual closed group selection.
