A communication system is disclosed which uses system frames of a first and a second type. In a system frame of the first type communication with a mobile telephone is subject to a restriction and in a system frame of the second type communication with said mobile telephone is not subject to said restriction. It is determined whether or not to communicate with said mobile telephone, in a current system frame, in dependence on whether the current system frame is a first type of system frame or a second type of system frame. The first type may be a dormant or wake-up system frame while the second type may be an active frame and contain paging information. By only listening to the active (or paging frames) a Discontinuous Reception (DRX) period can be extending beyond a length of a System Frame resulting in greater power savings. |
