A method of communication, comprising: determining, by a network node of a first network, that an access terminal requesting to establish communication at the first network is subscribed at a second network; obtaining, by the network node of the first network, service context information for the access terminal from the second network; obtaining closed subscriber group subscription information for the access terminal from a closed subscriber group subscriber server in the first network, that at least stores closed subscriber group subscription information for visiting access terminals, subscribed at the second network, wherein the closed subscriber group subscription information identifies at least one closed subscriber group that the access terminal is allowed to access; and controlling the requested communication based on the closed subscriber group subscription information, wherein the requesting to establish communication comprises the access terminal requesting to access a femto access point associated with a closed subscriber group; and wherein the controlling of the requested communication comprises: determining whether the closed subscriber group of the femto access point is listed in the closed subscriber group information of the access terminal; and determining whether to reject or accept the requested access based on the determination of whether the closed subscriber access group of the femto access point is listed in the closed subscriber group subscription information. determining, by a network node of a first network, that an access terminal requesting to establish communication at the first network is subscribed at a second network; obtaining, by the network node of the first network, service context information for the access terminal from the second network; obtaining closed subscriber group subscription information for the access terminal from a closed subscriber group subscriber server in the first network, that at least stores closed subscriber group subscription information for visiting access terminals, subscribed at the second network, wherein the closed subscriber group subscription information identifies at least one closed subscriber group that the access terminal is allowed to access; and controlling the requested communication based on the closed subscriber group subscription information, wherein the requesting to establish communication comprises the access terminal requesting to access a femto access point associated with a closed subscriber group; and wherein the controlling of the requested communication comprises: determining whether the closed subscriber group of the femto access point is listed in the closed subscriber group information of the access terminal; and determining whether to reject or accept the requested access based on the determination of whether the closed subscriber access group of the femto access point is listed in the closed subscriber group subscription information. determining whether the closed subscriber group of the femto access point is listed in the closed subscriber group information of the access terminal; and determining whether to reject or accept the requested access based on the determination of whether the closed subscriber access group of the femto access point is listed in the closed subscriber group subscription information.
