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