    摘要： A bit encoding system for use with a bus (7) of a distributed microcontroller network (200,300), includes a waveform generator (100) for generating a substantially sinusoidal waveform. A modulation arrangement (340, 341) is arranged to amplitude modulate the waveform between first and second amplitudes to define first and second data values. A zero crossing point of the waveform is used to define timing information for the bus (7).

    摘要： A method of assessing a signal in a second capsule (114) within a cell (102) of RF capsules in a cellular communications system, wherein measurements indicative of the signal are made by a first capsule (112) whilst it is servicing a call. The present invention enables the smooth handover of calls between capsules, where mobile assisted handover is unavailable, whilst reducing the system complexity and cost overheads prevalent in current systems.

    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mode of operation of the terminal (300) where the terminal (300) will maintain that availability when the UIM (400) is withdrawn from the terminal (300) and repeat the process at a different terminal (301) for a different set of services.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： In a cellular communication system (10), such an EDGE Compact system supporting discontinuous downlink control channel transmissions (12), a multiframe control channel (100) contains a multiplicity of signalling blocks (B-B11) partitioned by bursts associated with frequency correction (CFCCH) and synchronisation (CSCH). A scanning subscriber unit (64-70) wishing to access the cellular system (10) is designed to take power measurements of an incident frequency environment to identify a cell capable of providing service to the subscriber unit. With downlink control channel transmissions sent at full power by a serving base station (42-56), the multiframe (100) is structured to ensure that signalling blocks (B0, B3, B6, B9) are regularly transmitted throughout the multiframe (100). Additionally, with regard to particularly significant control signalling blocks, such as those of a broadcast control (CPBCCH) and a paging (CPCCH) nature, these are sequenced into the multiframe (100) such that any variation in a basic distribution of such control blocks in the multiframe follows an underlying pattern. In other words, in relation to CPBCCH and CPCCH logical channels, there is a fixed allocation scheme of control signalling block transmissions, although interlacing may vary the exact content of each block according to a defined transmission sequence between CPBCCH and CPCCH.

    摘要： The invention concerns a digital radio (2) for pseudo-duplex radio communication, and a method of transmission time mediation for pseudo-duplex radio communication.
    A digital radio (2) is in time division duplex communication with a second digital radio (4) over a single radio channel. Control of the radio channel may reside with either radio. However, authority for a radio to change the frame format in order to increase the proportion of time for which it transmits always resides entirely with the radio currently transmitting the least per frame. This is also the radio which transmits first in each frame. This arrangement lows rapid response to a need for a radio to move from listening to speaking mode, thereby reducing speech clipping.
    When the digital radio (2) and the second digital radio (4) are transmitting for equal proportions of the frame, authority to change the frame format passes to the radio that is transmitting at that instant.
    The apparatus and method of the invention provide a rapid switching of transmission mode, with minimal speech clipping when a user of the radio (2) starts to speak.
