Triggering of bitrate request for codec rate adaptation
A first user equipment (UE) device receives a configuration for a first timer from a base station that is serving the UE device. The first UE device also receives a recommended bitrate from the base station. The recommended bitrate is to be used for a Voice over Long-Term Evolution (VoLTE) call or a Video over Long-Term Evolution (ViLTE) call between the first UE device and a second UE device. The first UE device activates the first timer in accordance with the configuration. The first UE device is prohibited from transmitting a bitrate query to the base station while the first timer is running. Upon receiving a recommended bitrate that is below a Guaranteed Bit Rate for the call between the first UE device and the second UE device, the first UE device stops the first timer and transmits a bitrate query to the base station.
1. A method comprising:
receiving, at a first user equipment (UE) device, a configuration for a first timer;
receiving, at the first UE device, a recommended bitrate from a base station serving the first UE device, the recommended bitrate to be used for a call between the first UE device and a second UE device, the call being either a Voice over Long-Term Evolution (VoLTE) call or a Video over Long-Term Evolution (ViLTE) call;
activating the first timer in accordance with the received configuration;
prohibiting the first UE device from transmitting a bitrate query to the base station when the first timer is running; and
upon receiving a recommended bitrate that is below a Guaranteed Bit Rate (GBR) for the call, stopping the first timer.
2. The method of claim 1 , further comprises:
upon receiving the recommended bitrate, restarting the first timer.
3. The method of claim 1 , further comprises:
upon receiving the recommended bitrate, stopping the first timer.
4. The method of claim 1 , wherein the configuration prevents the first UE device from stopping the first timer before the first timer expires.
5. The method of claim 1 , further comprises:
upon receiving a recommended bitrate that is below a Guaranteed Bit Rate (GBR) for the call, allowing the first UE device to transmit a bitrate query to the base station;
upon transmission of the bitrate query, activating a second timer; and
prohibiting the first UE device from transmitting another bitrate query when the second timer is running.
6. A user equipment (UE) device comprising:
a receiver configured to:
receive, from a base station serving the UE device, a configuration for a first timer, and
receive, a recommended bitrate from the base station, the recommended bitrate to be used for a call between the UE device and another UE device, the call being either a Voice over Long-Term Evolution (VoLTE) call or a Video over Long-Term Evolution (ViLTE) call; and
a controller coupled to the receiver, the controller configured to:
activate the first timer in accordance with the received configuration,
prohibit the UE device from transmitting a bitrate query to the base station when the first timer is running, and
stop the first timer, upon receiving a recommended bitrate that is below a Guaranteed Bit Rate (GBR) for the call.
7. The UE device of claim 6 , wherein the controller is further configured to restart the first timer, upon receiving the recommended bitrate.
8. The UE device of claim 6 , wherein the controller is further configured to stop the first timer, upon receiving the recommended bitrate.
9. The UE device of claim 6 , wherein the configuration prevents the first UE device from stopping the first timer before the first timer expires.
10. The UE device of claim 6 , wherein the controller is further configured to:
allow the UE device to transmit a bitrate query to the base station, upon receiving a recommended bitrate that is below a Guaranteed Bit Rate (GBR) for the call,
activate a second timer, upon transmission of the bitrate query, and
prohibit the UE device from transmitting another bitrate query when the second timer is running.
11. A system comprising:
a base station; and
a first user equipment (UE) device being served by the base station, the first UE device comprising:
a receiver configured to:
receive, from the base station, a configuration for a first timer, and
receive a recommended bitrate from the base station, the recommended bitrate to be used for a call between the first UE device and a second UE device, the call being either a Voice over Long-Term Evolution (VoLTE) call or a Video over Long-Term Evolution (ViLTE) call, and
a controller coupled to the receiver, the controller configured to:
activate the first timer in accordance with the received configuration,
prohibit the first UE device from transmitting a bitrate query to the base station when the first timer is running, and
stop the first timer, upon receiving a recommended bitrate that is below a Guaranteed Bit Rate (GBR) for the call.
12. The system of claim 11 , wherein the controller of the first UE device is further configured to restart the first timer, upon receiving the recommended bitrate.
13. The system of claim 11 , wherein the controller of the first UE device is further configured to stop the first timer, upon receiving the recommended bitrate.
14. The system of claim 11 , wherein the configuration prevents the first UE device from stopping the first timer before the first timer expires.
15. The system of claim 11 , wherein the controller of the first UE device is further configured to:
allow the first UE device to transmit a bitrate query to the base station, upon receiving a recommended bitrate that is below a Guaranteed Bit Rate (GBR) for the call,
activate a second timer, upon transmission of the bitrate query, and
prohibit the first UE device from transmitting another bitrate query when the second timer is running.
