The UE VoIP engine monitors the network pattern periodicity and implements a scalable scheduling strategy that can adapt the VoIP engine and audio driver scheduling to the current local radio configuration in one embodiment. By adapting its scheduling, the VoIP engine can reduce mouth-to-ear delay or power consumption without impacting the audio encoding quality. The UE VoIP engine sends some scheduling preference to the network base station. The network base station monitors UE preferences and decide whether to ignore or accept UE preferences and allows the UE to operate in the conditions that provides the best tradeoff between power consumption and mouth-to-ear delay.

Monitoring network periodicity and in response adapting packet scheduling

A user equipment device (UE) comprises physical layer circuitry configured to transmit and receive radio frequency electrical signals with one or more nodes of a radio access network, an audio subsystem configured to generate frames of audio data, and processing circuitry. The processing circuitry is configured to calculate a time delay from generation of an audio data frame by the audio subsystem of the UE device to transmission of an audio data packet by the physical layer circuitry during a voice call, and decrease the time delay to a delay value that preserves a specified minimum time for delivery of the generated audio data frame to the physical layer circuitry to meet a scheduled transmission time of the audio data packet.
