Increasing Battery Performance for a Device That Uses Power Saving Features
Described herein are systems and methods to increase battery life of a user equipment (UE) by reducing the amount of time a UE spends in active time listening for paging messages following mobile originate (MO) or mobile terminated (MT) data transfers. A network node may receive, from a UE, a message including an identifier of the UE and a request to set the duration of an active time timer to zero. The network node may determine whether any MT traffic is available for the UE, and send a message to the UE including the duration of the active time timer or some other indicator to indicate to the UE whether or not MT data is awaiting transmission.
1 . A method in a user equipment (UE), the method comprising:
generating, by a UE, a first message comprising an active time request, a UE identifier of the UE, and a first indication indicating mobile terminated (MT) services are not requested;
sending, by the UE, the first message to a network node;
receiving, by the UE, a second message from the network node comprising an active time response and a registration message response;
determining, by the UE, an active time value based upon the active time response;
in response to determining the active time value, setting, by the UE, an active time timer to the active time value; and
in response to determining the active time value, enabling, by the UE, power saving, after expiration of the active time timer.
2 . The method of claim 1 , wherein the active time response comprises a T3324 Information Element value.
3 . The method of claim 1 , further comprising receiving, by the UE, mobile terminated (MT) traffic via a radio resource control (RRC) connection when an access node is configured to maintain the RRC connection.
4 . The method of claim 1 , wherein the active time request comprises a request to set the active time value to zero, and wherein the active time response comprises the active time value set to a value greater than zero.
5 . The method of claim 1 , wherein the registration message response comprises a 5G message that acknowledges a REGISTRATION message.
6 . A user equipment (UE) comprising:
a memory; and
a processor coupled to the memory, the processor configured to:
generate a first message comprising an active time request, a UE identifier of the UE, and a first indication indicating mobile terminated (MT) services are not requested;
send the first message to a network node;
receive a second message from the network node comprising an active time response and a registration message response;
determine an active time value based upon the active time response;
in response to the active time value being determined, set, by the UE, an active time timer to the active time value; and
in response to the active time value being determined, enable, by the UE, power saving, after expiration of the active time timer.
7 . The UE of claim 6 , wherein the active time response comprises a T3324 Information Element value.
8 . The UE of claim 6 , wherein the processor is further configured to receive mobile terminated (MT) traffic via a radio resource control (RRC) connection when an access node is configured to maintain the RRC connection.
9 . The UE of claim 6 , wherein the active time request comprises a request to set the active time value to zero, and wherein the active time response comprises the active time value set to a value greater than zero.
10 . The UE of claim 6 , wherein the registration message response comprises a 5G message that acknowledges a REGISTRATION message.
11 . A non-transitory computer program product comprising instructions which, when executed by a processor of a user equipment (UE), cause the UE to:
generate a first message comprising an active time request, a UE identifier of the UE, and a first indication indicating mobile terminated (MT) services are not requested;
send the first message to a network node;
receive a second message from the network node comprising an active time response and a registration message response;
determine an active time value based upon the active time response;
in response to the active time value being determined, set, by the UE, an active time timer to the active time value; and
in response to the active time value being determined, enable, by the UE, power saving, after expiration of the active time timer.
12 . The non-transitory computer program product of claim 11 , wherein the active time response comprises a T3324 Information Element value.
13 . The non-transitory computer program product of claim 11 , further causes the UE to receive mobile terminated (MT) traffic via a radio resource control (RRC) connection when an access node is configured to maintain the RRC connection.
14 . The non-transitory computer program product of claim 11 , wherein the active time request comprises a request to set the active time value to zero, and wherein the active time response comprises the active time value set to a value greater than zero.
15 . The non-transitory computer program product of claim 11 , wherein the registration message response comprises a 5G message that acknowledges a REGISTRATION message.
