1. User equipment (UE) for communicating with a communication system, the UE comprising:
- a transceiver configured to receive, from a core network entity of the communication system, at least one of an Attach Accept and a Routing Area Update (RAU) Accept message; and
a processor configured to synchronize an extended Discontinuous Reception (DRX) cycle to a time of receipt, by the transceiver, of the Attach Accept or the RAU Accept message, whereinthe transceiver configured to receive system information that include the number of active and the number of dormant System Frame (SF);
the transceiver configured to receive a paging message from Radio Access Network (RAN) that supports the extended DRX feature in the extended DRX cycle;
the transceiver configured to receive a paging message from Radio Access Network (RAN) that does not support the extended DRX feature in the non-extended DRX cycle.

Abstract
A communication system (100) 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 (3) is subject to a restriction and in a system frame of the second type communication with said mobile telephone (3) is not subject to said restriction. It is determined whether or not to communicate with said mobile telephone (3), 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.

9. A core network entity for a communication system for communicating with a user equipment (UE), the core network entity comprising:
-
a transceiver configured to send, to the UE, at least one of an Attach Accept and a Routing Area Update (RAU) Accept message; and a processor configured to synchronize an extended Discontinuous Reception (DRX) cycle to a time of sending the Attach Accept or the RAU Accept message, wherein the transceiver is configured to send the number of active and the number of dormant System Frames (SFs) to the UE and Radio Access Network (RAN). - View Dependent Claims (10, 11, 12, 13)
