Device-based system to estimate cellular wireless access network latency

A wireless device configured for latency estimation of a cellular wireless access link between the wireless device and a base station of a cellular wireless network, the wireless device comprising:

• one or more antennas;
• and
• a baseband processor communicatively coupled to the one or more antennas and a memory storing instructions that when executed configure the wireless device to:
• determine occurrence of a traffic burst between the wireless device and the base station, the traffic burst comprising an initial active time slot having a first non-zero grant allocation that satisfies a threshold value and a last active time slot having a second non-zero grant allocation that does not satisfy the threshold value;
• estimating an individual latency value for a time period with zero grant allocation within the traffic burst;
• processing the individual latency value to obtain an estimated latency statistic;
• and
• initiating at least one latency mitigation action when the estimated latency statistic satisfies a pre-determined latency threshold value.

A non-transitory computer-readable medium storing instructions for latency estimation of a cellular wireless access link between a wireless device and a base station of a cellular wireless network, the instructions comprising:

• instructions for determining occurrence of a traffic burst between the wireless device and the base station, the traffic burst comprising an initial active time slot having a first non-zero grant allocation that satisfies a threshold value and a last active time slot having a second non-zero grant allocation that does not satisfy the threshold value;
• instructions for estimating an individual latency value for a time period with zero grant allocation within the traffic burst;
• instructions for processing the individual latency value to obtain an estimated latency statistic;
• and
• instructions for initiating at least one latency mitigation action when the estimated latency statistic satisfies a pre-determined latency threshold value.
