Abstract: In various embodiments, a unidirectional broadcast network is utilized to provide digital content to users in a manner that allows users' computing devices to maintain synchrony with personal, relevant information. In at least some embodiments, the broadcast network utilizes a data channel and a signaling channel. The data channel is used for broadcasting data to various users, while the signaling channel—typically used for transmitting device or machine specific data—is used to transmit user-specific information associated with the information or data that the user finds relevant. This user-specific information can then be used by the user's mobile computing device to manage, e.g. record and place into device database for time shifted retrieval, such information or digital objects delivered over the broadcast data channel.

Abstract: A message exchange network is disclosed in which at least two different methods of storing messages in memories of message storage entities, e.g., a mobile handset, an SMSC, an e-mail client, or an e-mail server, are utilized based on the type and the content of the information contained within the message. An information service message containing information that is supercedingly updateable, e.g., stock quote, weather or traffic information, is stored using a replacement method by which an older message previously stored is replaced by a newly received message. All other types of messages are stored using an append method by which the newly received message is stored in an unoccupied available memory location. In a disclosed embodiment, message identifier included in the message itself provides information necessary to distinguish between the aforementioned two types of messages. In a disclosed embodiment, a block of message identifiers is reserved for storage of information service messages.

The reconstructed waveform can then be conventionally mixed and demodulated to extract useful signal information with enhanced receiver fidelity and sensitivity.

Abstract: Wireless communications are transmitted from at least two radioterminals to a base station co-channel over a return link using a return link alphabet. Wireless communications are also transmitted from the base station to the at least two radioterminals over a forward link using a forward link alphabet that has more symbols than the return link alphabet. The co-channel signals are deciphered at the receiver, while the radioterminals can use a smaller return link alphabet, which can reduce the power dissipation at the radioterminals.

Abstract: A method and apparatus prevents interference between a radio signal from RDS-TMC service provider for receiving traffic and travel data by an RDS-TMC receiver and a radio signal for transmitting audio, text, or image data from an FM modulator. The method includes the steps of starting an operation of the receiver system, stopping an operation of the FM modulator while keeping operation of the RDS-TMC receiver, examining whether an RDS-TMC signal from a service provider is available at a current location, receiving the RDS-TMC signal and retrieving RDS-TMC data therefrom, sending the retrieved RDS-TMC data to an audio/video system, and starting the operation of the FM modulator while allowing to output an FM signal from the FM modulator at allowable frequency bands which are outside of a blocked range to send data to the audio/video system.

Abstract: A set of new information elements are defined that are to be used between an access point and a client that allow an access point to advertise its capabilities, configuration, and/or parameters allowing the client to tune to the parameters prior to, during, or after associating with the access point. If the access point adjusts these parameters, the changes are advertised in subsequent beacons and response frames and the client responsive to receiving a beacon or response frame with changed parameters will change its parameters accordingly. If the station changes its operating parameters it will send a message to the access point informing the access point of the changes.

Abstract: A method and system for setting buffer size on a wireless communication device (WCD). A network entity receives a streaming-media-session initiation message from the WCD. The network entity determines a WCD buffer size, based at least on one or more features of the WCD, and sends to the WCD a directive to use the determined WCD buffer size. In one example, the network entity may determine the WCD buffer size based at least on media player version in use on the WCD and make and model of the WCD.

Abstract: Techniques are provided that allow power control and/or hand off operations to be performed in a wireless network in a manner that can enhance overall network throughput. In at least one embodiment, signal to noise ratio (SNR) and a signal to interference ratio (SIR) are obtained for a first mobile device within a wireless network. The SNR and SIR are then used to perform power control in the network (e.g., for the first mobile device). The SNR and SIR may also be used to facilitate hand off operations. In one approach, it may be determined whether the SNR and the SIR are each high or low, based on comparison with predetermined threshold values, in order to make a power control decision.

Abstract: A communication interface device includes a wireless Internet packet (IP) transceiver and a PCMCIA card electrically connected to the transceiver. Also, a universal serial bus (USB) connector is plugged into a hub that holds the PCMCIA card, with a cord extending from the USB connector and terminating in another USB connector. Accordingly, the device can be engaged with the PCMCIA bay of a user terminal or, if a user terminal has no PCMCIA bay, with a USB receptacle of the user terminal, to establish wireless communication. To simplify set-up, a CD containing all operating system versions of PCMCIA and USB drivers is engaged with the user terminal. The terminal's operating system is then automatically determined, and only the drivers associated with that operating system are loaded onto the terminal.

Abstract: The present invention provides a method and an apparatus of wireless communication with at least one wireless unit. The method includes detecting an indication of error in a plurality of traffic frames to control transmit power between at least a first and second forward link based on the indication of error. The method further includes receiving a plurality of consecutive traffic frames over at least two reverse links from a wireless unit to select a frame in soft handoff. To control transmit power, for example, a controller may perform reverse link error detection after frame selection. The controller detects a frame error to boost the transmit power, substantially correcting a link imbalance situation. In this way, by controlling transmit power in a spread spectrum wireless communication system to reduce call drops, a call drop rate may be significantly decreased while increasing capacity of radio frequency transmission.

Abstract: A multi-mode base station includes a transmit standby mode and an active mode. Transmit standby mode of base station operation is a low power/low interference level of operation as compared to active mode. In transmit standby mode at least some of the synchronization signaling such as pilot tone signaling is reduced in power level and/or rate with respect to the active mode. In transmit standby mode, the base station has no active state registered wireless terminals being serviced but may have some sleep state registered wireless terminals being serviced. Mode transitions from active to transmit standby may be in response to: a detected period of inactivity, scheduling information, base station mode change signals, and/or detected wireless terminal state transition. Mode transitions from transmit standby to active may be in response to: scheduling information, access signals, wake-up signals, hand-off signals, wireless terminal state change signals, and/or base station mode change signals.
