Abstract
A method and apparatus for improved battery performance of user equipment in a wireless network having multiple radio resource control (RRC) states, the method comprising the steps of: monitoring, at the user equipment, application data exchange; determining when no application on the user equipment is expected to exchange data; and initiating, from the user equipment, a transition to a less battery demanding radio resource control state or mode.
Claims12
A method, comprising:
- when a user equipment (UE) is in a first radio resource control (RRC) connected state or mode that is associated with a first discontinuous reception (DRX) cycle, determining, by the UE, that the UE expects no further data;
- and
- in response to the determining, transmitting, from the UE, a message to a node of a wireless network, wherein the message comprises a connection release indication, wherein the connection release indication indicates that the UE expects no further data, and wherein the connection release indication triggers a transition of the UE from the first RRC connected state or mode to a second RRC connected state or mode, wherein the second RRC connected state or mode is more battery efficient than the first RRC connected state or mode, and the second RRC connected state or mode is associated with a second DRX cycle that is longer than the first DRX cycle.
A user equipment (UE), comprising:
- at least one processor;
- one or more non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions, when executed, cause the UE to perform operations comprising:
- when the UE is in a first radio resource control (RRC) connected state or mode that is associated with a first discontinuous reception (DRX) cycle, determining, by the UE, that the UE expects no further data;
- and
- in response to the determining, transmitting, from the UE, a message to a node of a wireless network, wherein the message comprises a connection release indication, wherein the connection release indication indicates that the UE expects no further data, and wherein the connection release indication triggers a transition of the UE from the first RRC connected state or mode to a second RRC connected state or mode, wherein the second RRC connected state or mode is more battery efficient than the first RRC connected state or mode, and the second RRC connected state or mode is associated with a second DRX cycle that is longer than the first DRX cycle.
A non-transitory computer-readable medium storing computer instructions, that when executed by one or more hardware processors, cause a computing device to perform operations comprising:
- when a user equipment (UE) is in a first radio resource control (RRC) connected state or mode that is associated with a first discontinuous reception (DRX) cycle, determining, by the UE, that the UE expects no further data;
- and
- in response to the determining, transmitting, from the UE, a message to a node of a wireless network, wherein the message comprises a connection release indication, wherein the connection release indication indicates that the UE expects no further data, and wherein the connection release indication triggers a transition of the UE from the first RRC connected state or mode to a second RRC connected state or mode, wherein the second RRC connected state or mode is more battery efficient than the first RRC connected state or mode, and the second RRC connected state or mode is associated with a second DRX cycle that is longer than the first DRX cycle.
