  • Patent number: 7539186
    Abstract: A method and apparatus method of filtering packet data for an anonymous user device in a packet data network communication system includes a first step of initiating a call from an anonymous user device on a home network. A next step includes assigning an interim identity and interim IP address to the user device. A next step includes determining a level of service access of the data packets from the user device. A next step includes mapping the level of service access of the user device to the IP address. A next step includes defining permissible routing identities per the level of service access. A next step includes routing the data packets of the call along with the associated IP address to only those location addresses from the defining step.

  • Patent number: 7499733
    Abstract: A mobile communication device (100) includes a volatile memory (110) and a non-volatile memory (112). Instruction code for operating the mobile communication device is permanently stored in the non-volatile memory, and copied to the volatile memory for execution. The mobile communication device enters a hibernate mode which involves shutting down most of the mobile communication device except power to the volatile memory, which allows a nearly instant apparent start up of the mobile communication device at a later time.

  • Patent number: 7492885
    Abstract: A system and method of retrieving dispatch call information from a dedicated database by using interconnect call information. Interconnect call information from an interconnect communication system is obtained. The information identifies a target dispatch subscriber unit in a dispatch communication system. A request is received from a source dispatch subscriber unit. The request includes the interconnect call information. The interconnect call information identifying the target dispatch subscriber unit is extracted from the request. The interconnect call information of the target dispatch subscriber is related to unique dispatch call connection information of the target dispatch subscriber in a dedicated database. The unique dispatch call connection information concerning the target dispatch subscriber unit from the dedicated database in the dispatch communication system is retrieved using the extracted interconnect call information from the request.

  • Patent number: 7492753
    Abstract: A mobile terminal (302, 304) wakes up from a low power state and initiates a frame exchange in a wireless local area network that supports voice traffic by transmitting a polling frame (602). If the mobile terminal had voice data to send, it is included in the polling frame. In response to receiving the polling frame, the access point transmits a delay frame (604) to acknowledge receipt of the polling frame. If the access point has data for the polling mobile terminal, it transmits a non-delay frame (606) including the voice data, otherwise it transmits a null frame (702). The mobile terminal acknowledges the data from the access point (608), and goes back to sleep until the beginning of the next service interval.

  • Patent number: 7479928
    Abstract: An antenna radiator assembly (200) and radio communications assembly (1) comprising a circuit board (210) supporting electrical conductors (225), one of the electrical conductors (225) being coupled to a feed point (130), and the circuit board (210) having a ground plane (140) formed from at least one conductive sheet. There is a tuning resonator (132) comprising a tuning plate (310) operatively coupled to a tuning line (320), the tuning plate (310) being formed from part of the conductive sheet. An antenna radiator element (107) is spaced from said circuit board (210) and coupled to the feed point (130), and when viewed in plan view there is an overlapping area where an overlapping surface area of the antenna radiator element overlaps an overlapping surface area of the circuit board thereby forming a sandwiched dielectric region therebetween.

  • Patent number: 7449862
    Abstract: A device (102) contains a battery (116) which is recharged under control of a charge controller (112). An external power supply (104) provides charging current and voltage (106). A linear regulator (110) regulates the raw voltage provided by the external power supply. The device (102) also contains a heat-generating sub-system (118). To prevent excess heat generation while charging the battery, the battery charging regime is altered from a conventional regime when the heat-generating sub-system is active. Once the battery voltage reaches a charge limit (208), charge current is ceased (210) until the battery voltage falls to a lower limit (212), at which time the charging current is recommenced.

  • Patent number: 7447765
    Abstract: A method and apparatus method of filtering packet data for an anonymous user device in a packet data network communication system includes a first step of defining a special context information element containing special context information. A next step includes sending the special context information element in an activate packet data protocol (PDP) context request to a network to initiate a call from an anonymous user device. A next step includes receiving the activate PDP context request and the special context information element. A next step includes configuring the data packets so that only the special context is allowed. A next step includes assigning an interim identity and interim IP address to the user device. A next step includes mapping the data packets of the configuring step to the interim IP address of the user device. A next step includes defining permissible routing identities per the special context.

  • Patent number: 7443316
    Abstract: A method (300) for entering a character into an electronic device (100) is provided. The method (300) includes displaying (301) input character keys (204) on a touch sensitive region (202) of a display screen (105) of the device (100), the keys identifying an associated character. Next, a display step (309) shows at least one entered character in a display region (201) of the screen, the entered character having been selected by actuation of one of the character keys (204). Next, a group of potential subsequent characters that follow the entered character is predicted (311, 317). A second set of input character keys (205) identifying the potential subsequent characters is displayed (327). The second set of keys (205) are grouped together (323) such that their relative screen locations with respect to each other are different to that of corresponding keys in the first set of keys (204).

  • Patent number: 7428262
    Abstract: A method and apparatus for channel estimation in a rake receiver of a CDMA communication system operates with a finite-impulse-response channel estimation filter with L taps and having a fixed delay. A pilot sequence of a received sequence of data from a channel of the communication system on the rake receiver is input. A quality of the channel of the communication system is determined using noise or Doppler measurements. These measurements are used in adjusting a bandwidth of the filter to accommodate the channel quality while keeping the fixed delay, which minimizes the delay buffer size. The filter is then used to operate on the received sequence of data to provide coherent modulation.
