Abstract

Systems and methodologies are described that facilitate managing access control to Closed Subscriber Groups (CSGs) in a wireless communication environment. A user equipment (UE) can store an operator CSG list, which can be read only and controlled by an operator. Further, the operator CSG list can lack synchronization to a CSG subscription for the UE retained in the network. Thus, upon selecting to access a CSG cell associated with a CSG with a corresponding CSG Identifier (ID) included in the operator CSG list of the UE, a reject message that indicates that the UE lacks authorization for the CSG can be received. Moreover, the CSG ID can be stored as a forbidden CSG ID of the UE in a set of forbidden CSG IDs in response to receipt of the reject message when the CSG ID is included in the operator CSG list.
