Patent ID: 8913553

Claim:
A method of handling close subscriber group (CSG) list synchronization for a network in a wireless communication system, the method comprising: associating a first version number with a user subscribed CSG identities (IDs) list such that the first version number represents a version of the user subscribed CSG IDs list, wherein the user subscribed CSG IDs list is stored in the network; sending the first version number in a first OTA (over-the-air) message or in a first NAS (non-access stratum) message when the first version number is currently used by the network, wherein the first OTA message is intended to update an operator CSG list which is stored in a mobile device; comparing the first version number with a second version number associated with an operator CSG list stored in the mobile device; and updating the operator CSG list when the first version number does not match the second version number.
