Maintaining closed subscriber group information for access control

An apparatus for communication, comprising:

• an access controller configured to determine that an access terminal requesting to establish communication at a first network is subscribed at a second network;
• and
• a communication controller configured to obtain service context information for the access terminal from the second network, and further configured to obtain closed subscriber group subscription information for the access terminal from a server in the first network, wherein:
• the closed subscriber group subscription information identifies at least one closed subscriber group that the access terminal is allowed to access;
• and
• the access controller is further configured to control the requested communication based on the closed subscriber group subscription information.

• means for obtaining closed subscriber group subscription information for the access terminal from a server in the first network, wherein the closed subscriber group subscription information identifies at least one closed subscriber group that the access terminal is allowed to access;
• and
• means for controlling the requested communication based on the closed subscriber group subscription information.

A computer-program product, comprising:

• computer-readable medium comprising code for causing a computer to:
• determine that an access terminal requesting to establish communication at a first network is subscribed at a second network;
• obtain service context information for the access terminal from the second network;
• obtain closed subscriber group subscription information for the access terminal from a server in the first network, wherein the closed subscriber group subscription information identifies at least one closed subscriber group that the access terminal is allowed to access;
• and
• control the requested communication based on the closed subscriber group subscription information.

A method of communication, comprising:

• maintaining an operator list at an access terminal such that the operator list is updateable by a wireless operator;
• maintaining a user list at the access terminal such that the user list is updateable by the access terminal;
• removing a closed subscriber group identifier from a first list of the operator list and the user list;
• and
• removing the closed subscriber group identifier from a second list of the operator list and the user list based on the removal from the first list.
