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.

Claims

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 determine timing for extended Discontinuous Reception (DRX) based on receipt of the Attach Accept or the RAU Accept message.

2. The UE according to claim 1, wherein the received Attach Accept or RAU Accept message includes at least one extended DRX parameter, and wherein the processor is configured to determine a start of an extended DRX cycle based on the at least one extended DRX parameter.

3. The UE according to claim 2, wherein the transceiver is configured to send, to the core network entity, at least one of an Attach Request and a RAU request, and receive the Attach Accept or RAU Accept message including the at least one extended DRX parameter responsive to the sent Attach Request or RAU Request.

4. The UE according to claim 1, wherein the processor is configured to determine the start of an extended DRX cycle based on a reception time of the Attach Accept or RAU Accept message.

5. The UE according to claim 1, wherein the processor is configured to start the timing for the extended Discontinuous Reception (DRX) upon on receipt of the Attach Accept or the RAU Accept message.

6. The UE according to claim 2, wherein the processor is configured to control the transceiver to monitor for paging messages or system information messages in accordance with the extended DRX cycle in an idle mode.

7. The UE according to claim 4, wherein the processor is configured to control the transceiver to monitor for paging messages or system information messages in accordance with the extended DRX cycle in an idle mode.

8. The UE according to claim 1, wherein the transceiver is configured to provide to the core network entity information relating to a capability of the UE to communicate using extended DRX.

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 determine timing for extended Discontinuous Reception (DRX) based on sending the Attach Accept or the RAU Accept message.

10. The core network entity according to claim 9, wherein the Attach Accept or RAU Accept message includes at least one extended DRX parameter.

11. The core network entity according to claim 10, wherein the transceiver is configured to receive, from the UE, at least one of an Attach Request and a RAU request, and send the Attach Accept or RAU Accept message including the at least one extended DRX parameter responsive to the received Attach Request or RAU Request.

12. The core network entity according to claim 9, wherein the processor is configured to control the transceiver to transmit, to a Radio Access Network (RAN), messages that enable the RAN to transmit to the UE paging messages or system information messages in accordance with an extended DRX cycle.

13. The core network entity according to claim 9, wherein the transceiver is configured to receive, from the UE, information relating to a capability of the UE to communicate using extended DRX.

14. A method performed by user equipment (UE) for communicating with a communication system, the method comprising:

receiving, 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

determining timing for extended Discontinuous Reception (DRX) based on receipt of the Attach Accept or the RAU Accept message.

16. A non-transitory computer-readable medium comprising computer implementable instructions that, when executed by a programmable communication device, the programmable communication device to perform a method according to claim 14.

15. A method performed by a core network entity of a communication system, the method comprising:

sending, to a user equipment (UE), at least one of an Attach Accept and a Routing Area Update (RAU) Accept message; and

determining timing for extended Discontinuous Reception (DRX) based on sending the Attach Accept or the RAU Accept message.

17. A non-transitory computer-readable medium comprising computer implementable instructions that, when executed by a programmable communication device, the programmable communication device to perform a method according to claim 15.
