Abstract: The present invention is a method of coordinating an activity at a destination includes receiving a first signal indicative of a first location of a first party (110). The first signal is received at a destination of the first party. A second signal indicative of a second location of a second party is received at a destination (112), which is also the destination of the second party. A schedule is created (150) to coordinate the activity automatically at the destination. The schedule is based on the first and second signals indicative of the first and second locations and may include additional functions such as the estimated times of arrival of the first and second parties (120, 122). Also, the present invention is a method of notification upon arrival at a predetermined location (200) that includes receiving a first signal indicative of the location of a first party (210). A second signal is transmitted to a second party (230) when the location of the first party is equal to a first predetermined location (220). The activity is coordinated at a second location based on the second signal.

Abstract: Subscriber power levels are adjusted to enhance interference cancellation in a DS-CDMA communication system. A base-station (503) of the communication system receives signals from a plurality of subscribers (509-512) and evaluates each signal. Based on the evaluation, particular subscribers are commanded to control their power levels such that different predetermined targets for the particular subscribers are maintained. The predetermined targets include, but are not limited to, received power, frame erasure rate, bit error rate and signal quality. The resulting power levels received at the base-station (503) are substantially different, which is beneficially employed to enhance interference cancellation in the DS-CDMA communication system.

Abstract: A communication system utilizes multiple spreading codes to transmit high data rate information. The system codes high data rate user information (201) and partitions the coded information (202) into blocks comprised of two bits, B1 and B2. Based on the representation of bits B1 and B2, the system chooses one of a possible four spreading codes (W1 and W2 and their phase reversals W1' and W2') to be utilized for transmission. Once received, the transmitted signal is input into correlators (306, 309) specific to each spreading code W1 and W2, and the maximum absolute value output from the correlators (306, 309) is determined. From this determination, the transmitted spreading code W1, W2, W1' or W2' is determined. The use of multiple spreading codes allows for the transmission of high data rate information without altering the wireless air interface of the communication system.

Abstract: Audio degradation is minimized in scenarios where tandem coding occurs. One such scenario is in the environment of voice mail service. Characteristics of an audio information signal are determined, and the signal is classified (303) as to whether further coding (306) should be performed and, if so, which rate/type of coding should be performed. Characteristics of the audio signal which are determined are, inter alia, quality characteristics, rate of previous coding, type of previous coding and the source of previous coding of the audio information signal. The source of previous coding determined may further include, inter alia, an analog network, a digital network, a PSTN or a wireless communication system. Based on this information, the voice mail service will either choose not to further code the audio information signal or code the audio information signal with the best coding algorithm available.

Abstract: A direct sequence code-division multiple access (DS CDMA) communication system schedules conveyance of blocks (400) of information such that the blocks arrive at a base-site (130) just-in-time for transmission during a discrete frame (301-305) of an air-interface. The DS CDMA communication system implements both circuit switching and packet switching approaches to provide trunking efficiencies while balancing between system loading constraints and time delay of blocks (400) during conveyance.

Abstract: A communication system having a site (42) employing a plurality of communication channels. Each channel is assigned a desired received signal strength threshold. A channel is assigned to a subscriber unit (43a, 43b) based upon the strength of the signal received at the site (42) and the power control range of the subscriber unit (43a, 43b). The selection of a channel may be performed either by the site (42) or the subscriber unit (43a, 43b). In an FDMA environment (50), each separate frequency division channel may be assigned different received signal strength thresholds. In a non-overlapping time interval (TDMA) environment (70), each separate time division channel may be assigned different received signal strength thresholds. In another embodiment (80), a combination of FDMA and TDMA environments can be used.

Abstract: A wireless communication device (104) comprising a transceiver (202), a memory portion (206) and a display (208). The transceiver (202) receives (704, 806) a data stream of media content from a remote device (102) on a periodic basis. The memory portion (206) stores (704, 806) the data stream in a content cache (306). The data stream is retrieved from the content cache (306) a portion at a time, and the display (208) displays (706, 808) the portion. The display (208) has a passive mode and an actuated mode. In the passive mode, dynamic media content is continually provided at the display (208) throughout operation. In the actuated mode, detailed content and/or functionality associated with the dynamic media content is provided. The touch screen (210) changes the display from the passive mode to the actuated mode upon activation.

Abstract: A code division multiple access (CDMA) communicating system reduces interference by reducing the encoding rate for selected mobiles. The system (400) primarily uses link related characteristics such as, inter alia, distance measurements, physical resource power, and mobile determined noise, to determine which mobiles require an encoding rate reduction. Once determined, the encoding rate of the determined mobiles is reduced, which in turn reduces self-interference and enhances system capacity.

Abstract: A method and apparatus for authentication of a client device (256) utilizing remote multiple access to a server device (200) that includes a first authentication application unit (420), positioned within the client device, and a second authentication application unit (408) positioned in the server device. The first authentication application unittransmits a first synchronization command (500) to the server device over the packet data network (424), and the second authentication application unit generates a user unit code and transmits (502) the generated user unit code to the client device over the packet data network in response to the first synchronization command. The first authentication application unit and the second authentication application unit store the generated user unit code, and the server device transmits a message (508) that includes a control command and the user unit code stored in the second authentication application unit to the client device over the packet data network. The first authentication application unit compares the user unit code received in the message with the user unit code stored in the client device and executes (510) the control command in response to the user unit code stored in the client device being the same as the user unit code received in the message.
