1. A network entity comprising: a transceiver that transmits a broadcasted system information message including a restricted operator service access indication from a serving cell of a network; and
a controller coupled to the transceiver, where the controller performs a radio resource control connection establishment procedure to receive an attach request message, where the radio resource control connection establishment procedure is for the restricted operator service access, and where the radio resource control connection establishment procedure includes receiving a RRCConnectionS etupComplete message from a mobile equipment to the network,
wherein the RRCConnectionSetupComplete message includes both a restricted operator service request and an attach request message including a restricted operator service attach type,
wherein the RRCConnectionSetupComplete message is received in response to the mobile equipment receiving a user request for a restricted operator service, sending the restricted operator service access indication from an access stratum layer to a non-access stratum layer, detecting restricted operator service access support is available in the serving cell based on the restricted operator service access indication, and determining to attach to the network supporting restricted operator service based on the user request.
