MOBILE DEVICE POWER CONTROL FOR DUAL TRANSFER MODE (DTM)

摘要

A system and method of re-distributing power output by a portable mobile communications device while operating in dual transfer mode (DTM) is disclosed. The device determines if more than one uplink slot is active 320 and if DTM is active 330. If so, power can be separately regulated 350 for packet switched and carrier switched uplink slots. The device determines whether the circuit switched slot is being used for a voice call that is not in a handsfree or speakerphone mode 510 and evaluates factors associated with the current operating conditions 520. New power settings are calculated 530 based on the mode for the active circuit switched slot and the factors associated with the current operating conditions of the device. The new power settings are then applied 540 to the active uplink slots such that power is re-distributed on a per slot basis that is not necessarily divided equally among all active slots.
