System and method for improved wireless telephone call reception notification

摘要

A cellular telephone (116) and a pager (118) having a common battery (256) are integrated into a single unit. The unit is maintained in a low-power receive page mode when not in use. An incoming call is processed first as a conventional pager message. The device receives the page and wakes from the low-power page mode. When the device has gone to full-power active mode, a cellular phone call is connected. A smart battery controller (254) for the unit is provided. The smart battery controller (254) monitors the power level left in the battery (256) and stops allowing telephone operations when power reaches a minimum level. For example, the level may be configurable by the user as the number of hours of paging that may be accommodated after cell phone operations are no longer permitted.
