A wireless apparatus including a machine-to-machine (M2M) device. The M2M device has an applications processing element, RF transceive elements, and a deep sleep controller. The applications processing element executes one or more functions corresponding to an M2M processing environment, and directs the transmission and reception of radio frequency (RF) messages. The RF transceive elements are operationally coupled to the applications processing elements and transmit and receive the RF messages over the one or more wireless communications links. The deep sleep controller is coupled to the applications processing element and the RF transceive elements, and directs the applications processing element to request a sleep time from a corresponding base station, and causes the M2M device to enter a deep sleep mode upon acceptance of the sleep time by the corresponding base station, where the deep sleep mode is entered by removing power from the RF transceive elements. |

1. A wireless system, comprising:
a machine-to-machine (M2M) device, comprising:
an applications processing element, configured to execute one or more functions corresponding to an M2M processing environment, and configured to direct the transmission and reception of radio frequency (RF) messages over one or more wireless communications links;RF transceive elements, operationally coupled to said applications processing elements, configured to transmit and receive said RF messages over said one or more wireless communications links; anda deep sleep controller, coupled to said applications processing element and said RF transceive elements, configured to receive a system parameters message comprising a deep sleep enabled parameter upon registration with a corresponding base station, wherein said deep sleep enabled parameter indicates that a deep sleep mode is supported by said corresponding base station, and configured to direct said applications processing element to request a sleep time from said corresponding base station by transmission of a power down registration message that includes a sleep period field indicating said sleep time according to the function:
SLEEP TIME=[2(SLEEP PERIOD/4)]×0.08 seconds, and configured to cause the M2M device to enter a deep sleep mode upon acceptance of said sleep time by said corresponding base station, wherein said deep sleep mode is entered by removing power from said RF transceive elements. |
