Method and apparatus of transition to a battery efficient state or configuration by indicating end of data transmission in long term evolution
View Patent ↗A method is provided for sending a Fast Dormancy (FD) indication from a User Equipment (UE) to an access device through a Media Access Control (MAC) layer. The method includes receiving an indication from an upper layer that there is no more data for a prolonged period of time and generating and sending a MAC control element to the access device.
1. A method performed by a user equipment (UE), the method comprising:
determining whether a type of one or more bearers assigned to the UE is a background type or an interactive type;
determining a status of an inhibit timer reflecting whether the inhibit timer has expired or is not running;
determining whether to send a request for a more energy efficient state or mode based on the determined type of the one or more bearers and the status of the inhibit timer, wherein an inhibit timer value represents a time duration during which the UE is prevented from sending a subsequent request for the more energy efficient state or mode; and
transmitting the request based on the determining of whether to send the request for the more energy efficient state or mode.
2. A method performed by a network element, the method comprising:
determining whether a type of one or more bearers assigned to a user equipment (UE) is a background type or an interactive type;
determining whether to permit the UE to send a request for a more energy efficient state or mode based on the determined type of the one or more bearers assigned to the UE;
generating an indication based on the determining;
setting an inhibit timer value, wherein the inhibit timer value represents a time duration during which the UE is prevented from sending a subsequent request for the more energy efficient state or mode; and
transmitting the indication and the inhibit timer value to the UE.
3. The method of claim 2 , wherein transmitting the indication comprises transmitting a Radio Resource Control (RRC) Connection Reconfiguration message.
4. A user equipment (UE) comprising transmitter, receiver, memory and a processor, the processor configured to:
determine whether a type of one or more bearers assigned to the UE is a background type or an interactive type;
determine a status of an inhibit timer reflecting whether the inhibit timer has expired or is not running;
determine whether to send a request for a more energy efficient state or mode based on the determined type of the one or more bearers and the status of the inhibit timer, wherein an inhibit timer value represents a time duration during which the UE is prevented from sending a subsequent request for the more energy efficient state or mode; and
transmit the request based on the determination of whether to send the request for the more energy efficient state or mode.
5. A network element comprising transmitter, receiver, memory and a processor, the processor configured to:
determining whether a type of one or more bearers assigned to a user equipment (UE) is a background type or an interactive type;
determine whether to permit the UE to send a request for a more energy efficient state or mode based on the determined type of the one or more bearers assigned to the UE;
generate an indication based on the determining;
set an inhibit timer value, wherein the inhibit timer value represents a time duration during which the UE is prevented from sending a subsequent request for the more energy efficient state or mode; and
transmit the indication and the inhibit timer value to the UE.
6. The network element of claim 5 , wherein the transmitting the indication comprises transmitting a Radio Resource Control (RRC) Connection Reconfiguration message.
7. The method of claim 1 , further comprising receiving the inhibit timer value via radio resource control signaling.
8. The UE of claim 4 , wherein the processor is further configured to receive the inhibit timer value via dedicated radio resource control signaling.
