Abstract
Methods and apparatus may be used for selecting power saving mechanisms in a wireless transmit/receive unit (WTRU). For example a WTRU may support at least power saving mode (PSM) and/or extended discontinuous reception (eDRX) mode. The WTRU may send a request message including parameters associated with the supported power saving mechanisms such as an active time for PSM and a preferred DRX value for eDRX mode. The WTRU may receive an accept message including at least one selected parameter indicating the power saving mechanism for the WTRU selected by the network (NW). The WTRU may activate the selected power saving mechanism and may start a validity timer to define the duration of use of the selected power saving mechanism. In another example a WTRU configured to use eDRX may receive paging signals for system information (SI) change over a prolonged Broadcast Control Channel (BCCH) modification period.

Claim
1. A wireless transmit/receive unit (WTRU) configured to use a power saving state comprising:
a transmitter configured to send a request message, wherein the request message includes a plurality of parameters associated with a plurality of power saving states supported by the WTRU;
a receiver configured to receive, from a mobility management entity (MME), an accept message including at least one selected parameter associated with at least one selected power saving state, wherein the at least one selected power saving state is from the plurality of power saving states supported by the WTRU, wherein the accept message further includes at least one timer value associated with the at least one selected power saving state;
a processor configured to activate the at least one selected power saving state;
the processor is further configured to start a timer; and
on a condition that the timer expires after a period equal to the at least one timer value, the processor is further configured to deactivate the at least one selected power saving state.
2. The WTRU of claim 1, wherein the plurality of power saving states include at least power saving mode (PSM) and extended discontinuous reception (eDRX) mode.
3. The WTRU of claim 2, wherein a parameter associated with PSM is an active time and a parameter associated with eDRX mode is a preferred discontinuous reception (DRX) value.
4. The WTRU of claim 1, wherein the request message is a tracking area update (TAU) request message or an attach request message.
5. The WTRU of claim 1, wherein the at least one selected parameter has a different value than a corresponding parameter in the plurality of parameters associated with plurality of power saving states supported by the WTRU.
6. A method to use a power saving state performed by a wireless transmit/receive unit (WTRU), the method comprising:
sending a request message, wherein the request message includes a plurality of parameters associated with a plurality of power saving states supported by the WTRU;
receiving, from a mobility management entity (MME), an accept message including at least one selected parameter associated with at least one selected power saving state, wherein the at least one selected power saving state is from the plurality of power saving states, supported by the WTRU, wherein the accept message further includes at least one timer value associated with the at least one selected power saving state;
activating the at least one selected power saving state;
starting a timer; and
on a condition that the timer expires after a period equal to the at least one timer value, deactivating the at least one selected power saving state.
7. The method of claim 6, wherein the plurality of power saving states include at least power saving mode (PSM) and extended discontinuous reception (eDRX) mode.
8. The method of claim 7, wherein a parameter associated with PSM is an active time and a parameter associated with eDRX mode is a preferred discontinuous reception (DRX) value.
9. The method of claim 6, wherein the request message is a tracking area update (TAU) request message or an attach request message.
10. The method of claim 6, wherein the at least one selected parameter has a different value than a corresponding parameter in the plurality of parameters associated with plurality of power saving states supported by the WTRU.
