摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for providing encryption of signals to be transmitted between mobile stations, and enabling mobile-to-mobile calls via a common relay station which decreases the amount of delay appearing in a system.
SOLUTION: During call setting, a key for encrypting signals transmitted from mobile stations is established. The signal transmitted between mobile stations and encrypted is periodically monitored at a mobile switching center and compared with the established key. If the encrypted signal does not match the established key, the connection is terminated.

摘要： A satellite-cellular communication system includes a satellite based transceiver for transceiving two-way communications originated at a user terminal. As a part of call set up, a controller determines whether the user terminal should transmit in the uplink in either a wide band mode of operation or in a narrow band mode of operation. The controller then specifies to the user terminal the mode of operation through the transceiver. Whether the user terminal transmits in the uplink in a wide band or in a narrow band mode depends upon factors including the type of device, channel usage and efficiency in the channels to and from the satellite transceiver and the signal quality of the signals received at the transceiver.

摘要： In a time division multiple access (TDMA) radiotelephone communications system, a spread spectrum random access channel signal representing a random access message is communicated from a radiotelephone to a central station according to a spreading sequence. In response, a TDMA radiotelephone communications channel is assigned to the radiotelephone. A time division multiplexed radiotelephone communications signal is communicated between the radiotelephone and the central station on the assigned TDMA radiotelephone communications channel over a time division multiplexed carrier frequency band. Preferably, in communicating the spread spectrum random access channel signal, a random access channel signal, representing the random access channel message, is direct sequence modulated according to the spreading sequence to produce a direct sequence modulated random access channel signal. According to a two-stage detection aspect, a synchronization sequence may be associated with a plurality of spreading sequences. The synchronization sequence may be first detected from the communicated spread spectrum random access channel signal, and in response to detection of the synchronization sequence, one of the plurality of spreading sequences associated with the detected synchronization sequence may be detected. A station identification may be assigned to the radiotelephone, with the station identification preferably represented by a digital station identification word. The synchronization sequence and the spreading sequence may be identified from the station identification word, thus associating the synchronization and spreading sequences. The spreading sequence may also be randomly generated from the station identification word.

摘要： A portable phone capable of operating in cellular and satellite modes of communication is disclosed as including a main housing, circuitry located within the main housing for operating the portable phone in the cellular mode, circuitry located within the main housing for operating the portable phone in the satellite mode, a first antenna coupled to the cellular circuitry for receiving and transmitting signals in the cellular mode, and a second antenna coupled to the satellite circuitry for receiving and transmitting signals in the satellite mode. The second antenna can either be mounted to the main housing of the portable phone or housed within a flip cover coupled to the main housing. If provided, the flip cover is coupled to the main housing so as to be rotatable about a first axis and a second axis substantially perpendicular thereto. The first antenna may extend from the main housing, be printed on a surface of the flip cover, or be housed within the flip cover adjacent the second antenna.

摘要： A communication system provides efficient satellite communication in rural, remote, or sparsely populated areas, or in areas lacking a conventional telephone infrastructure, or in special purpose uses such as airport coverage. Subscribers in such areas communicate with the satellite via a simple, highly modular entry node located in a local area to be served. Subscriber units provide subscribers with access to the system. The subscriber units are connected to the entry node via local access loops provided by point-to-point wireless links between the subscriber units and the entry node. The entry node internally switches local traffic among subscribers and connects traffic to outside circuits, via wireless links with the satellite, as appropriate. The outside circuits are provided by the cooperative working of the satellite, an entry-node controller, and an earth station. The wireless links between the satellite and the entry node and the local access loops may operate at the same or different frequencies. If they operate at different frequencies, a frequency translator in the entry node controller matches the different frequencies. A subscriber unit may be used to provide the subscribers with access to the system such that speech compression and decompression takes place in the subscriber unit itself to avoid the effects of tandem coder/decoders.

摘要： A synchronization method and apparatus for synchronizing a receiver, such as a radiotelephone operable in a cellular communication system with a transmitter. Synchronization sequences are transmitted as parts of a control signal to the receiver. The synchronization sequences are formed of either a dotting sequence or a set of m-sequences. Such synchronization sequences are of high margins and also permit synchronization of the user terminal responsive to a reduced number of calculations.
