To alleviate the constraints imposed on communication system management by the assignment of dedicated ranges of MSISDNs and IMSIs to each particular home location register (HLRi, HLR2, HLRN), the present invention provides an ability to separate IMSIs and MSISDNs between HLR platforms by providing at least two data...

In a radio communication system (100), enhanced communication capability is provided while mamtaining standard channel modulation compatibility. At a transmitter (110, 200, 600), a first information signal is generated from data according to a predefined standard modulation scheme (212, 613). A second information si...

A radio communications system (200) that utilises multiple cells (201, 203, 205) to provide radio communication services to a plurality of mobile stations (405, 407).  In the cells (201) that service high concentrations of mobile stations within a very small geographic area, such as large office buildings (207), the...

A system and method for optimally compressing a software specification software language (100) includes supplying the software specification that is compressed (103) using a custom process. The customized software specification is then again compressed (105) using a standard compression techniques where it is con...

The present invention relates to a configurable subscriber communications unit operable in at least one local communications system and receiving communication system information from a common communications system, comprising: a receiver; a transmitter; a memory circuit; and a controller coupled to the transmit...

A receiving communication device (101) receives a reference signal transmitted through at least one of the antennas (106, 110, 112) of an antenna array of a transmitting communication device (102). The receiving communication device determines a weight to be associated with the at least one of the antennas, and tran...

A power amplifier circuit with temperature compensating level shifter for amplifying a radio frequency (RF) signal into an amplified RF signal, the power amplifier circuit characterized in that: a first input to receive the RF signal; an output to provide the amplified RF signal; a coupler circuit coupled to the ou...

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 teleph...

In response to an uplink transmission from a mobile unit (112) of a composite signal envelope (68) comprised from multiple sub-channels (10-16) of modulated data, a plurality of spatially separated antennas (118-120) of a base station (116) each receive the composite signal envelope (68) via different propagation pa...
