SYSTEM AND METHOD OF IMPROVING TALK-TIME AT THE END OF BATTERY LIFE
摘要
<p>A method by which a cellular phone (mobile station) operating in a multi-rate speech service environment and having a battery near its end of life may extend remaining talk time. The mobile station essentially reduces its transmit power settings while adjusting its codec mode 530 to compensate for the reduction in transmission power. This trade-off extends the remaining talk-time available when the phone's battery is nearing its end of life.</p>
