Abstract

The invention provides a mobile communication device and a method for handling network initiated detachment procedures. The mobile communications device is provided with a wireless module and a controller module. 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.

Description

technical field [0001] The present invention mainly relates to how to deal with an abnormal detachment procedure, especially how to deal with a detachment procedure initiated by a non-CSG base station, and the detachment reason for initiating the detachment procedure indicates that the non-CSG base station is not authorized Membership in the closed user group to which you belong. Background technique [0002] In a typical mobile communication system, a user equipment (User Equipment, UE) can perform wireless communication for voice and / or data services with a service network through a base station, wherein the wireless communication between the user equipment and the service network can be based on various based on wireless technologies, such as: Global System for Mobile communications (Global System for Mobile communications, GSM) technology, General Packet Radio Service (General Packet Radio Service, GPRS) technology, Enhanced Data rates for Global Evolution, EDGE) techno...
