The wireless module performs wireless transmissions and receptions to and from a cellular station. The controller module receives a detachment request message comprising a detachment cause from the cellular station via the wireless module, and determines whether the detachment cause indicates unauthorized membership of a closed subscriber group (CSG) supported by the cellular station. Also, the controller module determines whether the cellular station is a non-CSG cell in response to the detachment cause indicating unauthorized membership of the CSG supported by the cellular station, and keeps an allowed CSG list unmodified in response to the cellular station being a non-CSG cell."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatuses and methods for handling network initiated detachment procedures","description":"A mobile communications device with a wireless module and a controller module is provided.
