Abstract:
1. A method for reducing call drops between a wireless network and a wireless communication device in uplink power limited scenarios, the method comprising the wireless communication device: determining that the wireless communication device is experiencing an uplink power limited condition in which an uplink transmission power of the wireless communication device is limited to not exceed a level below a power class level of the wireless communication device; determining a transmission power imbalance representing a difference between a maximum uplink transmission power associated with the power class level of the wireless communication device and the uplink transmission power to which the wireless communication device is limited due to the uplink power limited condition; calculating a downlink power threshold by adding an offset equivalent to the transmission power imbalance to a threshold for sending a measurement report for triggering a handover as configured by a serving base station of the wireless network; determining based at least in part on measured downlink power that the downlink power threshold is satisfied; and sending the measurement report for triggering a handover to the serving base station of the wireless network in response to the downlink power threshold being satisfied.
