Codec-time aware scheduler for voice-over-IP

A wireless communication system comprising:

• one or more base stations configured for serving user equipment devices (UEs) in a given region using at least dynamic allocation of relative amounts UL and DL time division duplex (TDD) air interface resources,
• wherein the wireless communication system is configured to:
• determine usage demand for UL air interface resources relative to DL air interface resources as a function of time of day within the given region;
• and
• determine voice traffic load in the wireless communication system as a function of the time of day;
• based on the usage demand and on the determined voice traffic load as a function of time of day, create a schedule both for assigning a ratio of UL TDD allocation to DL TDD allocation, and for assigning a vocoder rate;
• and wherein the one or more base stations are further configured to (i) apply dynamic TDD allocation to set relative amounts of UL and DL air interface time for UEs served by the wireless communication system according to the schedule, instead of applying unscheduled dynamic TDD allocation of relative amounts of UL and DL air interface time, and (ii) adjust the vocoder rate according to the schedule.

A non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more processors of a wireless communication system configured for dynamic allocation of relative amounts UL and DL time division duplex (TDD) air interface resources, cause the wireless communication system to carry out operations including:

• determining usage demand for UL air interface resources relative to DL air interface resources as a function of time of day;
• determining voice traffic load in the wireless communication system as a function of the time of day;
• based on the usage demand and on the determined voice traffic load as a function of time of day, creating a schedule both for assigning a ratio of UL TDD allocation to DL TDD allocation and for assigning a vocoder rate;
• applying dynamic TDD allocation to set relative amounts of UL and DL air interface time for UEs served by the wireless communication system according to the schedule, instead of applying unscheduled dynamic TDD allocation of relative amounts of UL and DL air interface time;
• and
• adjusting the vocoder rate according to the schedule.
