    Abstract: A polar modulation power amplifier circuit includes a control circuit ( 101 ) to determine and provide a load selection signal ( 127 ), wherein the load selection signal ( 127 ) is determined responsive to a requested power signal ( 119 ). A power amplifier ( 113 ) is responsive to a power control signal ( 141 ), for amplifying an RF signal ( 139 ) to produce an amplified signal ( 145 ), having an output power level. A variable impedance matching circuit ( 117 ) is responsive to the load selection signal ( 127 ), to adjust a relationship between the control level and the output power level, to produce a range-adjusted amplified signal ( 147 ).

    Abstract: The present invention provides a communication controller and a method for maintaining a communication connection during a cell reselection. The communication connection is maintained by changing between a first operating mode, such as a packet data mode, which does not support the maintenance of a communication connection throughout a cell reselection, and a second operating mode, such as a circuit switched mode, which does support maintenance of a communication connection during a handover. Use of a virtual mobile switching center in the base station subsystem facilitates the conversion and routing of circuit switched data, transmitted between the mobile subscriber and the base transceiver station, to the packet data network while in a circuit switched mode.

    Abstract: A dual autodiplexing antenna (300) redirects power flow (303) from an unloaded antenna to a loaded antenna, thereby improving communication performance under loaded conditions. The dual autodiplexing antenna (300) includes a first antenna (101) disposed at a first end (103) of a portable two-way communication device (100). A second antenna (102) is disposed at the distal end (104) of the portable two-way communication device (100). The first antenna (101) and second antenna (102) are coupled to a transceiver (107) by a first transmission line matching circuit (201) and a second transmission line matching circuit (202), respectively. In one embodiment, the first antenna (101) is configured to primarily operate in a first bandwidth, while the second antenna (102) is configured to primarily operate in a second bandwidth. When one of the first antenna (101) or second antenna (102) is loaded, power flow (303) is redirected to the lesser loaded antenna.

    Abstract: The present invention provides a method for establishing direct mobile to mobile communication between cellular mobile terminals. The method includes selecting a frequency designated as a mobile communication frequency within a cellular communication system, and transmitting a communication initiation sequence at the selected frequency by a first mobile terminal. A second mobile terminal then monitors the designated mobile communication frequencies, and detects the communication initiation sequence. In at least one embodiment, selecting a frequency includes determining the region in which the first mobile terminal is operating, and selecting a mobile communication frequency for the determined region. In at least a further embodiment, the mobile communication frequency is a mobile transmission frequency for the determined region. In at least a still further embodiment, selecting a frequency includes selecting a frequency that is designated as a mobile transmit frequency in a first supported region and is designated as a mobile receive frequency in a second supported region.

    Abstract: A method and apparatus is provided for configuring a wireless communication module ( 220 ) for optimal performance with a portable communication handset ( 210 ). When coupling of a portable electronic handset ( 210 ) and a wireless communication module ( 220 ) is detected ( 602, 702 ) the portable electronic handset ( 210 ) uploads configuration information ( 604, 606, 608, 610 ) to the wireless communication module ( 220 ). The wireless communication module ( 220 ) receives the configuration information ( 704, 706, 708, 710 ) from the portable communication device ( 210 ) and configures the operational parameters of the wireless communication module ( 220 ) in response to the configuration information ( 714, 716, 718, 720 ).
