This European Telecommunication Standard (ETS) gives an overview of the tasks undertaken by a GSM mobile station (MS) when in idle mode, that is, switched on but not having a dedicated channel allocated, e.g. not making or receiving a call. It also describes the corresponding network functions. Note: The term GSM MS is used for any type of MS supporting one, or combinations, of the frequency bands specified in GSM 05.05 (e.g. GSM 900 and DCS 1800).
