Abstract: A system, method and computer readable medium for scroll displaying of message information stored in message memory (418) of a wireless messaging device (400). The wireless messaging device (400) fetches additional message information from a wireless messaging server (112) over a wireless network, and stores in message memory (418) the additional message information received over the wireless network prior to reaching the end of scroll displaying the stored message information. Additionally, a plurality of received messages can be scroll displayed according to a message receive order or other priority.

Abstract: A mobile station establishes a schedule by which data is exchanged with an access point. The schedule allows the mobile station to use a low power mode at times outside of the scheduled service periods. However, the mobile station may occasionally need to retrieve additional data from the access point, or transmit additional data to the access point, and so initiates an unscheduled service period to do so.

Abstract: Apparatus and corresponding method in a wireless mobile device (10) for classifying each of a plurality of audio bits obtained from a vocoder (104) into one class of a plurality of classes according to a predetermined importance of each audio bit, wherein each of the plurality of classes has an associated error correction process and an associated repeat diversity process. Error correction and repeat diversity are applied to a portion of the plurality of classes based on the associated error correction and repeat diversity processes. The method may be implemented by a processor (10) executing routines stored in a memory (110).

Abstract: A device (102) that can perform voice recognition operates with a removable media or memory (104) that is used to store information records (126). To save memory space in the removable media, voice recognition tags (118), used to perform voice recognition, are not stored in the removable media, but are stored in the device. Since the media is removable, the device must check to make sure the records stored in the media are usable with the voice recognition tags. This is accomplished by generating a key (306) whenever a new voice recognition tag is trained (304). The key is stored in the device, or in the media, or both. Upon initialization of the device, (202), the device searches (206) the media for records and checks (210) to see if the key corresponding to the record matches any keys in the device. When a match is found the record is associated (214) with the corresponding voice recognition tag. Voice recognition tags with no corresponding records are deleted or ignored.

Abstract: A wireless communications device (102) includes a flip assembly 106 that includes a speaker (120) and that has a GPS antenna (104) mounted about a far edge. The flip assembly (106) further has a GPS RF amplifier (314) mounted adjacent to the GPS antenna (104) for amplifying signals received by the GPS antenna (104) and providing those amplified signals to a GPS RF stripline (312). The GPS RF stripline (312) includes a flexible RF stripline (404) to accommodate rotationally opening and closing of the flip assembly (106). Positioning of the GPS antenna (104) about the far edge of the flip assembly (106) removes the GPS antenna from a main housing assembly (108) of the wireless communications device (102) and provides for better GPS signal reception performance.

Abstract: Graphical display data representing an image for display is packetized for wireless transmission. At least one command for displaying the image from the data is within the packet. The command is used to display the image, as represented by the packetized data, in related configurations to create an animated display or at predetermined times or intervals to make the image appear spontaneously or be removed after a predetermined period of time for later display or are erased. Transmission of the packetized data occurs when the receiving devise is idle. The transmission of the packets may be interrupted by a present need to establish a communications channel with the receiving device, for example for voice communication or for transmission of hyperlinked data. A handshake protocol is used to assure the parts of the packetized data are successfully downloaded.

Abstract: An initiating mobile station (102) subscribes to a wireless communication system (109) for mobile communication service. A wireless remote access server (WRAS) (118) interacts with the wireless communication system as a subscribing mobile station would, but provides network connectivity to data information network, such as the Internet (108). The WRAS includes radio devices (120, 122) for communicating with the wireless communication system, and network control and routing (124). The WRAS sets up a network session with the target (104 or 106) to facilitate communication between the initiating mobile station and the target, via the wireless communication system and the network.

Abstract: A radio (100) provides multiple audio modes of operation, such as a cellular and dispatch modes. Illumination devices (108, 110) are located near the radio's audio sources (104, 106) and become activated to indicate to the user which mode of operation is present.

Abstract: A mobile station (106) establishes a real time communication link via an access point (102) for carrying voice or other time-sensitive data. A WLAN subsystem (204) of the mobile station is normally kept in a low power state. Upon initiating a communication link the mobile station signals to the access point that unscheduled power save delivery mode will be used (614), and the access point reserves resources to assure the necessary quality of service. The mobile station initiates a frame transaction by first powering up the WLAN subsystem (712), acquiring the WLAN channel (407), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with an aggregate response. The aggregate response commences by transmitting all data in an aggregate buffer, including both reserved and unreserved data buffers. Upon successful receipt of the aggregate response, the mobile station places the WLAN subsystem back into a low power state.

Abstract: A transmitter (100) uses a low noise up mixer (112) so that no filter is needed at the output of the up mixer. A Cartesian feedback path (122) enhances the linearity of the transmitter, and provides a feedback signal that is subtracted from a baseband signal (118) that is generated by a baseband signal generator (120). The subtraction is performed by a combiner (116) and produces an amplified error signal (111). A gain control circuit (130) samples the baseband signal and the amplified error signal, and determines a ratio of these signal levels. The gain control circuit compares the present ratio value with a preferred ratio value, and adjusts the gain of the power amplifier (102) so as to keep the present ratio value substantially equal to the preferred ratio value.

Abstract: The invention provides a method and apparatus for allowing a multi-mode mobile communication unit (102) to switch efficiently between communication systems. The method includes creating and adaptively updating a footprint database (210) relating the coverage of the multiple communication systems. The footprint database (210) comprises a plurality of system lists (220). The system lists (220) each include a plurality of cell entries (222) linking cells of a particular system to cells in other systems. Each of the plurality of cell entries is identified by a cell frequency (342) and a color code (344). The method further comprises the step of installing and dynamically updating the footprint database (210) on the mobile unit (102). Accordingly, an apparatus of the invention includes a mobile unit (102) having the aforementioned database installed thereon.

Abstract: A mobile communication device (104) loads an application bundle (200), which includes a software application (202) and an indication of a time limited license (206). To enforce the time limited license, the mobile communication device, upon attempting to invoke the application code (310), obtains a secure time reading (312). It is contemplated that a secure time server (116) may be used to facilitate license enforcement. Once the secure time reading is obtained, the mobile communication device compares the time with the license period, and executes the code only if the time reading is within the license period.

Abstract: A method for setting up a dynamic group call includes the step (202) of selecting a group of radios (120, 121) by a dynamic group call originator (122). Once the radios that will be part of the dynamic group have been selected, the dynamic group call originator (122) transmits a dynamic group call message(s) to each of the selected radios. Each of the transmitted dynamic group call message(s) includes the IP address of one of the selected radios. Upon each of the target radios receiving their individually directed message, the target radios (120, 121) can each send an optional acknowledgment message to the dynamic group call originator (122). The originator (122) and the target radios (120, 121) then switch to the dynamic talk group number assigned by the dynamic talk group message.

Abstract: A frequency management scheme for a hybrid communications/positioning device, such as a cellular/GPS or other combined device, generates a local clock signal for the communications portion of the device, using a crystal oscillator or other part. The oscillator output may be delivered to a phase locked loop to drive a high-frequency clock for the cellular or other communications portion of the hybrid device. A processor may determine frequency error between the phase locked loop and base station or other reference, to derive a digital frequency tracking message. A Doppler search or other logical control message may likewise be communicated from the processor to a GPS or other positioning receiver. The GPS receiver circuitry may consequently adjust Doppler center, window width or other parameters to enhance time to first fix or other performance.

Abstract: A method for automatically entering a SIM's PIN in case of a reset or other condition includes the steps of storing (206) in RAM the PIN after it has been verified (204). Whenever a reset condition occurs, the PIN that is cached in RAM (106) is automatically presented to the SIM (214). In order to make sure that the PIN stored in RAM (106) in not corrupted during a reset condition, the inverse (208) or other coded form of the PIN is also stored in RAM (106) as an additional check of the correctness of the stored PIN.

Abstract: A technique is used in a spread spectrum communication system (100) such as cdma2000 or UMTS to assign a subscriber unit (120) a link for a supplemental channel, during a handoff period. The technique includes queuing a data packet for transmission to the subscriber unit at a packet transmission time (221) determined by a queue delay (220), obtaining pilot signal strength measurements of at least two active downlinks (125) of the subscriber unit that are measured substantially at the packet transmission time, and determining a strongest one of the at least two active downlinks from the pilot signal strength measurements. The pilot signal strength measurements are obtained by determining a pilot signal measurement time (PSMT) for the subscriber unit, calculating a pilot signal measurement delay (PSMD) from the PSMT and the queue delay, and transmitting a pilot signal measurement request (PSMRQ) to the subscriber unit after the PSMD.

Abstract: A wireless communication system (402) that provides dispatch communication service, and talk group calling service, supports several talk groups (408, 410). A console (412) operated by a subscribing organization resides outside of the communication system. The console is considered a member of the talk groups, and interacts with the communication system over an internet access, via one or more gateways (416, 418). The gateways operate like base stations that provide the air interface to the mobile communication devices. When the operator of the console wishes to patch the talk groups together, call information received from the first talk group at the console prompts the console to initiate a talk group call for the second talk group. When the second talk group call is set up, the console forwards call information such as identifiers and audio information to the second talk group. This allows the members of the second talk group to participate in talk group calls made in the first talk group.
