CSG membership indication
First Claim
1. A method of communication, comprising:
- setting a timer for determining that a subscriber is no longer a member of a closed subscriber group;
receiving a first indication of increased registration attempts of an access terminal associated with the subscriber prior to expiration of the timer;
setting a second indication that the subscriber is no longer a member of the closed subscriber group based at least in part on the received first indication, the second indication being set to a value that indicates that removal is pending for an identifier of the closed subscriber group from a list of closed subscriber groups at an access terminal associated with the subscriber;
removing the identifier of the closed subscriber group from closed subscriber group subscriber information for the subscriber upon the expiration of the timer;
detecting whether the access terminal accesses any access point associated with the closed subscriber group for a defined period of time of the timer; and
sending the second indication to a mobility manager.

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.
