Abstract: An emergency call apparatus is provided that includes an applications processor and a code division multiple access (CDMA) modem. The applications processor is configured to receive current location data and vehicle crash data from sensors disposed in an automotive vehicle, and is configured to automatically establish a voice connection with an emergency services center, and is configured to transmit the location and vehicle crash data to the emergency services center within a prescribed time period. The CDMA modem is coupled to the applications processor and is configured to format and transmit a plurality of protocol data units (PDUs) over a single traffic channel that includes both primary traffic corresponding to the voice connection and other traffic corresponding to the location and vehicle crash data.

Abstract: 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.
