One example of a method of managing battery usage by a wireless mobile communication device includes reading a start time, an end time, and other information, for each of a number of extents, and identifying one or more handovers, using the start time, end time, and other information, wherein the one or more handovers are handover activity. Next, the handover activity is compared to an allowable threshold, and a determination made as to when the number of idle mode handovers exceeds the allowable threshold. Finally, battery usage by the wireless mobile communication device is reduced by taking action to reduce the number of idle mode handovers that occur.

Wireless device battery optimization by suppressing oscillation in cell scope during idle mode

In a wireless call between two mobile phones, metrics of conversational latency between the two parties determines a measure of Quality of Service (QoS) for the one or more carriers of real-time transport protocol RTP packets. Packages of metrics are collected at the two terminal devices, each of which may have an independent local clock. A Quality of Service estimation apparatus transforms metric packages into a pair of probability distribution functions for a plurality of real-time transport protocol packets between two endpoints. The offset between the two independent local clocks is determined or eliminated. A key performance indicator is determined for End-to-End RTP stream delay by transforming the timestamps associated with transmission and reception at user equipment hosting a QoS agent.

End-to-end real-time transport protocol (RTP) packet transmission delay measurement apparatus and method

A method detects misconfiguration of a wireless network which wastes battery power in mobile devices within a location area of the network. A data collection agent installed in a wireless device records and reports idle-mode handovers. An analytics circuit reads RF measurements and locations from these reports to suggest where handover zones may be optimized or IRAT cell resection parameters are defective. A mobile device may self-tune battery consumption by determining its individual location areas of high battery consumption; desensitizing itself to cell signal strength instability; and increasing its tenacity to a most recently used cell.
