Abstract: To provide a mobile telephone terminal which is capable of mitigating burden on the user when telephone directory information is backed-up and reducing likelihood of erasure of the telephone directory information. If a user newly registers a telephone number list or changes or deletes the telephone number list stored in a telephone directory storage unit by actuating a key entry unit when telephone directory update notification mail transmission preset flag and automatic transmission preset flag are in the on-states, a control unit automatically transmits a telephone directory update notification mail in which update contents of the telephone directory information are described to a mail address which is stored in a transmission destination mail address area.

Abstract: A method and system for optimizing channel access scheduling for multiple wireless computing devices over a wireless network improves channel access efficiency with respect to a primary channel. An access point, or host computer, includes a host transceiver for receiving control information from the wireless computing devices over a low power channel. Upon receiving the control information, the access point applies a scheduling algorithm to schedule channel access for the wireless computing devices to transmit data over the primary communication channel. The wireless computing devices include a low power radio for receiving scheduling information via the low power channel during idle periods. When the scheduling information is received, the wireless computing device activates its primary channel network interface components to communicate data through the primary channel.

Abstract: A DPRAM is placed in the RF path before the digital to analog converter, to provide dynamic path gain compensation to the digital signal prior to conversion to an analog signal. The DPRAM stores corrections to the signal to compensate for amplitude losses in the signal arising from heat and non-linearities. The DPRAM has two sets of identical addresses. A logic switch, alternately directs an input signal to one of the two sets of addresses. Pre-calculated signal values which compensate for path gain are stored in one of the two sets of addresses in the DPRAM. The signal input to the DPRAM is directed to the other block. The value of the signal input to the DPRAM will determine the address to which the new value can be found. It is this new value which is actually input to the DAC and from which an analog signal is created.

Abstract: A telematics communication system (100) receives an input supply voltage (Vin) (122) from a battery (102) charged by an alternator (101) in an automotive vehicle. The telematics communication system (100) includes a transceiver (104) having a transmitter (107) and a variable delta voltage tracking regulator (VDVTR) (109).

Abstract: A mobile radiotelephone terminal having a satellite radiotelephone and a Global Positioning System (GPS) obtains a coarse position of the mobile radiotelephone terminal from satellite radiotelephone system communications. The GPS receiver uses the coarse position to determine an accurate position of the mobile radiotelephone terminal. Accordingly, by obtaining a coarse position from the satellite radiotelephone systems communications, the computation time for the GPS receiver to compute an accurate position of the mobile radiotelephone terminal may be reduced. By allowing a reduction of computation time by the GPS receiver, an accurate position may be obtained more quickly and/or with reduced power.

The contactless interface may preferably be fed independently of the mobile apparatus.

Abstract: In a cellular telecommunications system, when a user equipment unit (UE) [30] seeks to use a FACH common transport channel in a cell controlled by the drift radio network controller (DRNC) [262], the drift radio network controller (DRNC) signals to a serving radio network controller (SRNC) [261] whether the drift radio network controller (DRNC) requires initiation of a Common Transport Channel Resource Initialization Procedure. If the signaling indicates that the drift radio network controller (DRNC) does not require initiation of the Common Transport Channel Resource Initialization Procedure, the serving radio network controller (SRNC) has discretion whether to initiate the Common Transport Channel Resource Initialization Procedure with respect to the user equipment unit (UE) in the cell.

Abstract: A portable radio telephone handset operates as a data transfer terminal as well as an analog cellular telephone subscriber station. Two modes of operation, an analog cellular communication mode and a Cellular Digital Packet Data (CDPD) mode, are available in the handset. The handset distinguishes between paging signals indicating CDPD mode communications and those indicating analog cellular communications. The handset also automatically preempts CDPD communications in favor of analog cellular communications such as those carried out in an AMPS configuration. The handset maintains an active status on a CDPD communication channel during a “sleep mode”, when the handset can carry out AMPS activity.

Abstract: A method for re-selecting control channels in a mobile station reduces the use of resources by limiting an evaluation of candidate control channels to those channels which satisfy certain criteria and are deemed to be eligible control channels. As a consequence, resources are not spent on attempting to re-select a control channel that is not compatible with the mobile station.

Abstract: In a frequency modulation radio receiver with direct conversion, a local oscillator signal is generated having a frequency within a preselected frequency range and the frequency is varied in response to a variable low frequency signal; the local oscillator signal is mixed with a received signal to provide a baseband signal. The variable low frequency signal is generated by a controlled oscillator in inverse relationship to a direct current component in said baseband signal. In a frequency modulation radio transceiver a broadcast function is provided by varying the low frequency signal with an information signal with the resulting local oscillator frequency being varied accordingly and amplified for broadcast. The transceiver is controlled to operate alternately in either a receive mode and a broadcast mode at substantially the same frequency.

Abstract: Dividing the function of wireless handset control from the function of telecommunication call control in a software architecture of a wireless telecommunication system. The wireless handset control function follows the wireless handset as it registers and is handed off from switch node to switch node; the telecommunication call control function remains on the switch node on which the wireless handset first became active and remains on that switch node until the wireless handset becomes inactive. Upon the wireless handset becoming inactive, the wireless telecommunication call control function is transferred to the switch node on which the wireless handset is currently registered.

Abstract: A portable communications subscriber unit operates as a data transfer terminal as well as an analog cellular telephone M-ES. Two modes of operation, an analog cellular communication mode and a Cellular Digital Packet Data (CDPD) mode, are available in the subscriber unit. The subscriber unit distinguishes between paging signals indicative of a CDPD mode of communication and those indicative of an analog cellular mode of communication. The subscriber unit automatically preempts CDPD communications in favor of analog cellular communications such as those carried out in an AMPS system. The present inventive method enables the subscriber unit to remain registered in the CDPD communication system using a CDPD “sleep mode” while performing activities on the AMPS system. Another aspect of the present invention facilitates the automatic switching of subscriber unit displays to correspond to the communication system with which the unit is presently communicating.
