Abstract

A user equipment (UE) may support establishing an E-UTRAN New Radio-Dual Connectivity (EN-DC) connection with a telecommunication network that involves both a Long-Term Evolution (LTE) connection and a fifth generation (5G) connection. However, the EN-DC connection may drain a battery of the UE more quickly than the LTE connection would alone. Accordingly, an EN-DC switcher executing on the UE can determine when the UE should use the LTE connection alone or use the EN-DC connection, for example based on factors that may indicate when a user of the UE is less likely to perceive improved throughput or other benefits of the EN-DC connection.

Claims (99)

1 . A method, comprising:

determining, by a user equipment (UE) associated with a telecommunication network, one or more factors associated with a status of the UE, wherein the UE supports establishing a dual connection that includes:

a first connection between the UE and a first base station of the telecommunication network; and

a second connection between the UE and a second base station of the telecommunication network;

transitioning, by the UE, from an idle state to a connected state;

establishing, by the UE, the first connection with the first base station;

determining, by the UE, that the one or more factors meet a condition for using the first connection without using the second connection;

using, by the UE, the first connection to send or receive data without using the second connection;

receiving, by the UE, a measurement request from the telecommunication network; and

suppressing, by the UE and in response to determining that the one or more factors meet the condition, sending a measurement report to the telecommunication network in response to the measurement request,

wherein suppressing sending the measurement report causes the telecommunication network to avoid establishing the second connection with the UE.

2 . The method of claim 1 , wherein:

at least one of the one or more factors is a display status of a display of the UE,

the display status indicates that the display is turned off, and

the condition is that the display is turned off.

3 . The method of claim 1 , wherein:

at least one of the one or more factors is sensor data,

the sensor data indicates that a user is not looking at a display of the UE, and

the condition is that the user is not looking at the display.

4 . The method of claim 1 , wherein:

at least one of the one or more factors is an application type or data type associated with the data to be sent or received,

the data to be sent or received is at least one of:

under a threshold size, or

associated with a background process, and

the condition is that the data to be sent or received is under the threshold size or is associated with the background process.

5 . The method of claim 1 , wherein:

at least one of the one or more factors is a battery level of a battery of the UE,

the battery level indicates that an energy level of energy stored in the battery is below a threshold percentage, and

the condition is that the battery level is below the threshold percentage.

6 . The method of claim 1 , further comprising:

establishing, by the UE, the dual connection with the telecommunication network; and

sending, by the UE in response to determining that the one or more factors meet the condition, a dual connection disablement message to the telecommunication network,

wherein the dual connection disablement message causes the second base station to disable the second connection.

7 . The method of claim 1 , further comprising receiving, by the UE from the telecommunication network, a configuration that adjusts the condition.

8 . A user equipment (UE), comprising:

one or more processors;

one or more radio interfaces configured to support establishing a dual connection, with a telecommunication network, that includes:

a Long-Term Evolution (LTE) connection between the UE and an LTE base station of the telecommunication network; and

a fifth generation (5G) connection between the UE and a 5G base station of the telecommunication network; and

memory storing computer-executable instructions that, when executed by the one or more processors, cause the UE to perform operations comprising:

determining one or more factors associated with a status of the UE;

determining that the one or more factors meet a condition for using the LTE connection without using the 5G connection; and

using the LTE connection to send or receive data without using the 5G connection,

wherein at least one of the one or more factors is a display status of a display of the UE, the display status indicates that the display is turned off, and the condition is that the display is turned off.

9 . The UE of claim 8 , wherein:

the one or more factors further includes sensor data,

the one or more factors indicate that the UE does not detect a user looking at the display, and

the condition further includes that the UE has not detected a user is looking at the display.

10 . The UE of claim 8 , wherein:

at least one of the one or more factors is an application type or data type associated with the data to be sent or received,

the data to be sent or received is at least one of:

under a threshold size, or

associated with a background process, and

the condition further includes that the data to be sent or received is under the threshold size or is associated with the background process.

11 . The UE of claim 8 , wherein:

at least one of the one or more factors is a battery level of a battery of the UE,

the battery level indicates that an energy level of energy stored in the battery is below a threshold percentage, and

the condition further includes that the battery level is below the threshold percentage.

12 . The UE of claim 8 , wherein the operations further comprise:

transitioning the UE from an idle state to a connected state;

establishing the LTE connection with the LTE base station;

receiving a 5G measurement request from the telecommunication network; and

suppressing, in response to determining that the one or more factors meet the condition, sending a 5G measurement report to the telecommunication network in response to the 5G measurement request,

wherein suppressing sending the 5G measurement report causes the telecommunication network to avoid establishing the 5G connection with the UE.

13 . The UE of claim 8 , wherein the operations further comprise:

establishing the dual connection with the telecommunication network; and

sending, in response to determining that the one or more factors meet the condition, a dual connection disablement message to the telecommunication network,

wherein the dual connection disablement message causes the 5G base station to disable the 5G connection.

14 . The UE of claim 8 , wherein the operations further comprise receiving, by the UE from the telecommunication network, a configuration that adjusts the condition.

15 . One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to perform operations comprising:

determining one or more factors associated with a status of the UE, wherein the UE supports establishing a dual connection, with a telecommunication network, that includes:

a Long-Term Evolution (LTE) connection between the UE and an LTE base station of the telecommunication network; and

a fifth generation (5G) connection between the UE and a 5G base station of the telecommunication network;

establishing the LTE connection with the LTE base station;

determining that the one or more factors meet a condition for using the LTE connection without using the 5G connection;

receiving a 5G measurement request from the telecommunication network; and

based on the determining that the one or more factors meet the condition, suppressing sending a 5G measurement report to the telecommunication network in response to the 5G measurement request,

wherein suppressing sending the 5G measurement report causes the telecommunication network to avoid establishing the 5G connection with the UE.
