  • Patent number: 11381997
    Abstract: A base station receives a bitrate query from a first user equipment (UE) device being served by the base station. The bitrate query can be a request for a bitrate increase or decrease. The base station transmits a bitrate recommendation to the first UE device. The bitrate 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 bitrate to be used for the VoLTE call, based on the bitrate recommended by the base station. The first and second UE devices implement a bitrate for the VoLTE call and provide feedback to the base station.
