Abstract

Problems caused by interaction between paging optimization and synchronizing CSG information are mitigated by setting a network indication indicating, for example, that a subscriber is no longer a member of a CSG, but the network has not yet received confirmation that an access terminal associated with the subscriber has been informed of this. A timer-based scheme may be employed for removing a CSG ID from the subscriber information for a subscriber once it is determined that the subscriber is no longer a member of the CSG. In addition, a temporary member of a CSG may determine whether it is still a member of a CSG upon expiration of a CSG timer. Also, the frequency with which an access terminal registers may be changed based on various criteria. Furthermore, an allowed CSG list may be selectively included in a page message depending on the destination of the page message.
