Dynamic bitrate adjustment in user equipment for voice frames
A recently granted patent (Publication Number: US12004011B2) discloses a User Equipment (UE) system designed to optimize voice frame transmission in a mobile communication network. The UE includes a wireless transceiver for communication with the network and a controller that accumulates Transport Block Size (TBS) data over time. By performing an Exponential Moving Average (EMA) on the TBS data, the controller estimates the bitrate of voice frames to be transmitted. If the estimated bitrate differs from the current bitrate during specific periods, the controller adjusts the bitrate accordingly. This adjustment is based on counters tracking high and low bitrate periods, ensuring efficient bitrate management for voice frame transmission.
Furthermore, the UE system incorporates a coder/decoder (codec) to handle voice frames based on the current bitrate. The patent outlines a method executed by the UE, involving the accumulation of TBS data, estimation of bitrate, and adjustment of the current bitrate based on high and low bitrate period counters. These counters track discrepancies between estimated and current bitrates, allowing for dynamic bitrate adjustments to enhance voice frame transmission efficiency. The method also includes selecting the highest allowable bitrate from a rate mapping table based on the estimated TBS, ensuring optimal bitrate selection for voice frame transmission. Overall, the patented technology aims to improve the performance of voice frame transmission in mobile communication networks through intelligent bitrate management strategies.
