Abstract
A base station transmits a rate recommendation to a first user equipment (UE) device. The rate recommendation is to be used for a Voice over Long-Term Evolution (VoLTE) call between the first UE device and a second UE device. In some instances, the first UE device and the second UE device negotiate the rate to be used for the VoLTE call, based on the rate recommended by the base station. If the negotiated rate is supported by the base station and/or matches a supported codec rate, the UE devices implement the rate and provide rate feedback to the base station.
Claims4
A first user equipment (UE) device comprising:
- a receiver configured to receive from a second UE device, information indicating a first bit rate requested by the second UE device to be used in a voice packet communication with the first UE device;
- and
- a transmitter configured to transmit a request message to a base station, in response to the first bit rate exceeding a second bit rate currently supported by the first UE device, the request message used for receiving a bit rate recommendation from the base station, wherein
- the receiver is further configured to receive the bit rate recommendation from the base station.
An apparatus for controlling a first user equipment (UE) device, the apparatus comprising a memory and a processor electrically coupled to the memory, the processor configured to:
- receive from a second UE device, information indicating a first bit rate requested by the second UE device to be used in a voice packet communication with the first UE device;
- transmit a request message to a base station, in response to the first bit rate exceeding a second bit rate currently supported by the first UE device, the request message used for receiving a bit rate recommendation from the base station;
- and
- receive the bit rate recommendation from the base station.
A method for a first user equipment (UE) device comprising:
- receiving from a second UE device, information indicating a first bit rate requested by the second UE device to be used in a voice packet communication with the first UE device;
- transmitting a request message to a base station, in response to the first bit rate exceeding a second bit rate currently supported by the first UE device, the request message used for receiving a bit rate recommendation from the base station;
- and
- receiving the bit rate recommendation from the base station.
