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.
Claims5
A base station comprising:
- a receiver configured to receive, from a first user equipment (UE) device, a message to check if a first bit rate can be provided by the base station, the message transmitted in response to the first bit rate exceeding a second bit rate currently supported by the first UE device, the first bit rate being requested by a second UE device to be used in a voice packet communication with the first UE device;
- a transmitter configured to transmit a bit rate recommendation to the first UE device in response to receiving the message;
- and
- a controller configured to execute the functions of the receiver and the transmitter.
A method for a base station comprising:
- receiving from a first user equipment (UE) device, a message to check if a first bit rate can be provided by the base station, the message transmitted in response to the first bit rate exceeding a second bit rate currently supported by the first UE device, the first bit rate being requested by a second UE device to be used in a voice packet communication with the first UE device;
- and
- transmitting the bit rate recommendation to the first UE device in response to receiving the message.
A system comprising:
- a first user equipment (UE) device;
- a second UE device;
- and a base station, wherein the first UE device comprises:
- a receiver configured to receive, from the 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 message to the base station in response to the first bit rate exceeding a second bit rate currently supported by the first UE device;
- and
- a controller configured to execute the functions of the receiver and the transmitter, the message to check if the first bit rate can be provided by the base station, wherein
- the receiver is further configured to receive the bit rate recommendation from the base station.
