Abstract

Wireless transmit receive units (WTRUs) and methods implemented in WTRUs are described. A method includes transmitting idle mode discontinuous reception (DRX) parameters to a serving general packet radio service (GPRS) support node (SGSN)/mobile management entity (MME) during one of a tracking area update (TAU) and a routing area update (RAU) procedure and implementing the DRX mode of operation using the transmitted DRX parameters. The DRX parameters are for a DRX mode of operation that has longer DRX intervals than a regular DRX mode of operation.

Claims

1. A wireless transmit/receive unit (WTRU) comprising:

a transceiver configured to transmit idle mode discontinuous reception (DRX) parameters to a serving general packet radio service (GPRS) support node (SGSN)/mobile management entity (MME) during one of a tracking area update (TAU) and a routing area update (RAU) procedure, wherein the DRX parameters are for a DRX mode of operation that has longer DRX intervals than a regular DRX mode of operation; and

a processor configured to control the WTRU to implement the DRX mode of operation using the transmitted DRX parameters.

2. The WTRU of claim 1, wherein the WTRU is configured to communicate via machine-to-machine (M2M) type communication.

3. A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:

transmitting idle mode discontinuous reception (DRX) parameters to a serving general packet radio service (GPRS) support node (SGSN)/mobile management entity (MME) during one of a tracking area update (TAU) and a routing area update (RAU) procedure, wherein the DRX parameters are for a DRX mode of operation that has longer DRX intervals than a regular DRX mode of operation; and

implementing the DRX mode of operation using the transmitted DRX parameters.

4. The method of claim 3, wherein the WTRU is configured to communicate via machine-to-machine (M2M) type communication.

5. A network node comprising:

a transceiver configured to receive idle mode discontinuous reception (DRX) parameters from a wireless transmit/receive unit (WTRU) during one of a tracking area update (TAU) and a routing area update (RAU) procedure, wherein the DRX parameters are for a DRX mode of operation that has longer DRX intervals than a regular DRX mode of operation; and

a processor configured to configure the WTRU to implement the DRX mode of operation using the received DRX parameters.

6. The network node of claim 5, wherein the network node is a serving general packet radio service (GPRS) support node (SGSN)/mobile management entity (MME).

7. The network node of claim 5, wherein the WTRU is configured to communicate via machine-to-machine (M2M) type communication.
