    摘要: A mobile communication system (101) having a layered architecture (401) communicates user and signalling data (1105) among components of the communication system in the form of information elements which are encapsulated within packets (1005) which may be passed across one or more system interfaces (1401). The mobile communication system comprises mobile user stations (102), base stations (104), and base station controllers (105) and operates as a transparent data pipeline between application end users, such as a telephone service (126), connected at base station controllers (105) and mobile user stations (102). In a particular embodiment, the interface between the base station (104) and the user stations (102) is a TDMA interface, and signalling traffic between the base station (104) and each of the user stations (102) is conducted in either a fast control traffic mode or a slow control traffic mode. In the fast control traffic mode, signalling messages are exchanged between the base station (104) and a user station (102) in a plurality of time slots (302) within a timespan of a single time frame (301 ); in the slow control traffic mode, signalling messages are exchanged between the base station (104) and a user station (102) in no more than a single time slot (302) within a timespan of a single time frame (301).

    摘要: A technique for spread-spectrum communication (figs. 1, 3, 12 and 14) which uses more than one mode and more than one frequency band. Selectable modes include a narrowband mode (113) and spread-spectrum mode (111), or cellular mode and microcellular mode. Selectable frequency bands include both licensed and unlicensed frequency bands, particularly frequency bands including the 902-928 MHz, 1850-1990 MHz and 2.4-2.4835 GHz frequency bands. Spread-spectrum communication channels are 10 MHz or less in width. The frequency band onto which spread-spectrum signals are encoded may be changed upon a change in environment or other control trigger, such as establishment or de-establishment of a communication with a private access network. A multi-band transmitter (fig. 12) comprises a single frequency synthesiser and a frequency source (606) (e.g. a local oscillator), coupled to selectable band pass filter (619, 620). A multi-band receiver (fig 14.) capable of monitoring one or more frequency bands comprises bank of bandpass filters (714, 715) and a demodulator comprising a single frequency synthesiser and a frequency source (721).

    摘要: A simple and flexible over-air protocol for use with a mobile telephone system, having hand-held telephones in a microcell or other type of cellular communication system. A method in which user stations communicate with one or more base stations to place and receive telephone calls, in which the user stations are provided a secure voice or data link and have the ability to handoff calls between base stations while such calls are in progress. Each base station has a set of "air channels" to which it transmits in sequence.
    The air channels supported by each base station are called that base station's "polling loop". A user station receives general polling information on an unoccupied air channel, transmits responsive information to the base station, and awaits acknowledgment from the base station. Each base station may therefore simultaneously maintain communication with as many user stations as there are air channels in its polling loop. The ability of a user station to communicate on any unoccupied air channel makes the protocol air-channel agile, while the stability of user station and base station clocks may define air channels, gaps, and minor frames.

    摘要: A system for accessing a telephone system (101) in which a set of user stations (102) are matched with a set of base stations (104) for connection to a telephone network (103). Each user station comprises a spread-spectrum transmitter (109) or receiver (108) and is capable cf dynamic connection to selected base stations (104). User stations may use CDMA, FDMA, TDMA or other multiple-access techniques to obtain one or more clear communication paths to base stations. Base stations are coupled to each other by means of a private exchange telephone system or other small business telephone system (such as a PBX, Centrex, or key-type system) so as to couple user stations in calls outside the telephone network. User stations may also be coupled directly or indirectly to the telephone network on their own or by another access path, such as narrowband or spread-spectrum cellular telephone circuits.
