摘要： In a picocell system (100), a first and a second base station (104, 108) is provided. A common Broadcast Control Channel is transmitted by the first and second base stations (104, 108) to a first and a second cellular telephone (120, 122). The first base station (104) is in communication with the first cellular telephone (120) and the second base station (108) is in communication with the second cellular telephone (122). Whilst a midamble of a time slot transmitted by the second cellular telephone (122) is being received, the second base station makes power measurements of transmissions from the first cellular telephone (120).

摘要： A common communications system (119) provides information regarding the availability of other local communication systems (111-117) within the common communications system coverage area to a generic, programmable subscriber unit (120). Geographical location information is then supplied to the common communications system (119) indicating position of the subscriber unit (120). The geographic information is used by either the common communication system (119) or subscriber unit (120) to provide information pertinent only to one or more local communications systems (111-117) that the subscriber unit (120) may select. The common communication system (119) or the subscriber unit (120) can also be used to selectively filter or extract information such that the information presented to the user is related to the geographical location. The subscriber unit (120) then selects one of the local communications systems (111-117) and receives enabling programming from that local communication system. The enabling programming permits the subscriber unit (120) to configure itself to operate on the selected communication system.

摘要： In the preferred embodiment, a Space Division Multiple Access (SDMA) radio communication system (100) utilises a base station (101) having a plurality of antenna elements (103) used to transmit and receive to multiple radio communication devices (107, 109) on a same frequency and time channel. A different set of beam forming weights is applied to communications for each radio communication device (107, 109) in such a way as to minimize the interference between the radio communication devices signals. A set of distance metrics is calculated utilizing the sets of weights for each pair of radio communication units sharing a channel. When any distant metric is less than a pre determined threshold value, one of the radio communication devices (107, 109) is reallocated to a new channel or a handover instruction is performed.

摘要： A method and apparatus enables selection a communication system when a user of a mobile unit is away from a home system to which it is registered. According to one novel aspect, the visited communication system broadcasts (402) a list of standardized type services including tariff information, which is used by the mobile unit to select a system. According to another novel aspect, the mobile initiates an outgoing call of a non-standardised type service by accessing (502) a candidate system and informing it of the location of the home network and desired service identifier. The candidate system obtains (504) the service information on this service from the home network, and then provides (546) a quotation for a required service. Also, a communication system according to the present invention minimises incoming call costs to the user wherein the home system polls (606) the communication systems within range of the mobile unit to select the best system to provide service.

摘要： The digital radio receiver processes received signals by first determining the values of data bits contained in the received signals. Second, the data bits are assessed a level of confidence to be applied to the data bits. This assessment is done at a group level and applied to each of the data bits contained within that group.

摘要： A system (100) has a single user identifier associated with a User Identity Module (UIM) (400) in order to access a particular set of services provided by a service provider (200) by a particular terminal (300). The UIM (400) is associated with the terminal (300) and the user chooses the services to be available at the terminal (300). The user can then select a mode of operation of the terminal (300) where the terminal (300) will maintain that availability when the UIM (400) is withdrawn from the terminal (300) and repeat the process at a different terminal (301) for a different set of services.

摘要： A communication system, such as a telepoint system, is provided comprising at least one base station (10), and at least one handset (11) having means for setting up a call over a radio channel with the base station and having means for receiving an over-the-air registration sequence from the base station and storing a number (TRD) in non-volatile memory (20) dependent on the over-the-air registration sequence. The base station has metering means (13) for metering charge units accrued during the call between the base station and the handset. Means (14) are provided at the base station for automatically generating a new over-the-air registration sequence to be sent to the handset in response to the metering means and transmitting (16) the new over-the-air registration sequence to the handset and replacing the number stored in non-volatile memory with a new number dependent on the new over-the-air registration sequence. The new number differs from the old number to reflect deduction of pre-paid charge units.

摘要： A feedback and shift unit is arranged to reduce to a minimum the number of processing steps required in a processor, such as a DSP, to achieve a particular operating function, such as a linear feedback shift or a stepping function used by encryption algorithms. The feedback and shift unit (50) comprises a linear feedback shift register (52) for storing a value of the feedback and shift unit. A tap register (56) stores a tap position indicator indicative of tap positions for the feedback and shift unit (50). An input provides data to the feedback and shift unit. A feedback matrix, coupled to receive the data from the input, provides data bits, generated in response to the data and the tap position indicator, that are shifted into the linear feedback shift register (52) to form the value stored therein.
