摘要： A communication device 200 capable of operating in a communication system 100 having a control system which generates information signals with redundant information is disclosed. The communication device comprises: a receiver 214 for receiving the information signals; a circuit which can determine the signal quality of the received information signals 234; and a controller 226 which decodes the received information signals, and further compares the signal quality of the information signals with a predetermined value, and decides if the received signal quality is at least equal to the predetermined value in order to only decode a portion of the information signal. Upon the communication device decoding a portion of the information signal, the communication device 200 is placed in a battery saving mode in order to conserve battery life.

摘要： A transceiver (100) is provided for transmitting during the transmission bursts (12) of a frame and receiving during the receiving time-slot windows (14). The transceiver (100) includes a receiver (320) for receiving a repeating radio frequency data (16) signal at any time within the receiving time-slot window (14) and for demodulating the repeating radio frequency data signal down to a baseband data signal. A data detector and clock recovery device (330) recovers the valid data (CHMP) from the baseband data signal. For controlling the receiver (320) and data detector and clock recovery device (330), a control circuit (400) modifies the receiving time-slot windows (14) to only receive and detect when valid data is expected (52).

摘要： A method for registration of a portable unit that may be utilized in a communication system that comprises a network controller, having a data base for storing portable identification numbers, a base station, and a portable unit, wherein a subscriber communicates to the network controller a first information set which comprises subscriber qualifying information, the portable identification number, and a key code that has been entered into the portable, and wherein the subscriber has entered a link identification number for over-the-air registration into a memory within the portable unit. The registration method comprises the following steps. The portable unit sends the base station a request for registration. The request for registration comprises the link identification number for over-the-air registration and the portable identification number. The base station receives the request for registration from the portable unit, and sends to the network controller a notice of the request for registration and the portable identification number. The network controller receives the notice of the request for registration from the base station, and determines whether the portable identification number is in the network controller data base, and whether the subscriber has been approved for registration. The network controller then sends to the portable unit, through the base station, a registration information signal if the network controller determines that the portable identification number for over-the-air registration is in the network controller data base, and that the subscriber has been approved for registration, the registration information signal comprising an encrypted secret subscriber identification number that has been encrypted with the key code, and an unencrypted link identification number for base station access.
