Application layer group services for machine type communications
Procedures, mechanisms, methods, and techniques are provided that trigger power saving mode (PSM) functionality in the at least one wireless transmit receive units, group of WTRUs or subset of the group of WTRUs. The trigger may be in response to an application layer request to set one or more predetermined PSM settings, wherein the trigger originates from one or more application servers (APs) directed to a core network by way of an interface such as an SCEF that may be included on a device (e.g., a gateway, computing device, and/or the like) and may be configured for enabling the application server to request enabling and disabling PSM functionality.
1. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
ending a power mode for a duration of a first time value of an active timer, wherein the power mode relates to saving power by deactivating a radio of the WTRU;
receiving an unsolicited configuration message indicating to register with a network to make power mode related changes;
sending an acknowledgement for the unsolicited configuration message;
sending a registration message to the network related to the power mode;
receiving a response message including instructions to change the active timer from the first time value to a second time value, and instructions to start the power mode at an expiration of the second time value of the active timer; and
starting the power mode at the expiration of the second time value.
2. The method of claim 1 , wherein receiving the second time value related to the power mode causes the WTRU to start the active timer.
3. The method of claim 1 , wherein the active timer is a mobility management timer.
4. The method of claim 1 , wherein the power mode ended based on the expiration of a configured periodic registration timer.
5. A wireless transmit/receive unit (WTRU), the WTRU comprising:
a processor, and
a transceiver coupled to the processor, the processor and transceiver configured to end a power mode for a duration of a first time value of an active timer, wherein the power mode relates to saving power by deactivating a radio of the WTRU;
the processor and transceiver configured to receive an unsolicited configuration message indicating to register with a network to make power mode related changes;
the processor and transceiver configured to send an acknowledgement for the unsolicited configuration message;
the processor and transceiver configured to send a registration message to the network related to the power mode;
the processor and transceiver configured to receive a response message including instructions to change the active timer from the first time value to a second time value, and instructions to start the power mode at an expiration of the second time value of the active timer; and
the processor and transceiver configured to start the power mode at the expiration of the second time value.
6. The WTRU of claim 5 , wherein receiving the second time value related to the power mode causes the WTRU to start the active timer.
7. The WTRU of claim 5 , wherein the active timer is a mobility management timer.
8. The WTRU of claim 5 , wherein the power mode is ended based on an expiration of a periodic registration timer.
