  • Method and apparatus for maintaining a suspension state after powering down and fully powering down upon expiration of a timer or low battery level
    Patent number: 7523326
    Abstract: It is an object of the present invention to shorten the time needed to start when a cellular phone is switched on. If a power key is switched off during operation, the display of an LCD is switched off, and key interrupts and the like are masked. In this case, data in the middle of the process of an application program in execution, execution addresses and the like are stored, and shift to a suspension state is signaled notified to a baseband unit. The CPU of an application unit is set to a deep sleep mode, and the cellular phone waits for a start instruction from the baseband unit.
