APPARATUSES, SYSTEMS, AND METHODS FOR MAINTAINING ALLOWED CLOSED SUBSCRIBER GROUP (CSG) LIST

摘要

A mobile communications device with a wireless module and a controller module is provided. The wireless module performs wireless transceiving to and from a cellular station of a service network, and the cellular station is associated with a Closed Subscriber Group (CSG) identification (ID) and configured to operate in a hybrid access mode. The controller module transmits a request message for Circuit Switched (CS) or Packet Switched (PS) domain to the cellular station via the wireless module, and receives a response message corresponding to the request message from the cellular station via the wireless module. Also, the controller module determines whether the response message indicates authorized membership of the CSG ID, and adds the CSG ID in an allowed CSG list in response to the CSG ID not being in the allowed CSG list and the response message indicating authorized membership of the CSG ID.
