Apparatuses, systems, and methods for handling detachment procedures upon expiration of closed subscriber group (CSG) subscription

摘要

A mobile communication device with a wireless module and a controller module is provided. The mobile communication device is attached to a service network via a cellular station for a non-emergency service, wherein the cellular station is associated with a Closed Subscriber Group (CSG). The controller module determines whether an emergency service is ongoing and initiates a detachment request message of the non-emergency service to the service network via the cellular station, only when no emergency service is ongoing. The wireless module transmits the detachment request message to the service network via the cellular station.
