Abstract: The present invention is directed toward distribution of web content to personal cellular telecommunications devices. The present invention proposes compiling syndicated items compilation files containing the entire contents of one or more syndicated information files and/or status notification compilation files containing a list of one or more syndication feeds and status information regarding same. Both types of compilation files can be Point-To-MultiPoint (P2MP) pushed to all available personal cellular telecommunications devices in one or more cells selected by a cellular operator using standardized P2MP push technology. Alternatively, status notification compilation files can be P2P pulled by or P2P pushed to particular personal cellular telecommunications devices. The present invention also proposes offering accessing full stories in formats other than conventional web page formats. Such non web page formats include inter alia SMS, MMS, email, and the like.

Abstract: Techniques for graceful coexistence of modules supporting multiple communication protocols are described. Graceful coexistence may be achieved by giving priority to a communication protocol having high priority data to send or receive. In one design, the priority of data to send via a wireless channel by a first module for a first communication protocol (e.g., IEEE 802.11) may be determined, e.g., based on data type, one or more data protocol header fields, an application originating the data, etc. Whether to send the data without delay may be decided based on the priority of the data. A second module for a second communication protocol (e.g., Bluetooth) may be requested to not transmit on the wireless channel in response to a decision to send the data without delay. The data may be sent via the wireless channel upon receiving an indication that the wireless channel is not occupied by the second module.

Abstract: Techniques for performing IP configuration after handoff in a WLAN are described. A station associates with a first access point in the WLAN and performs IP configuration to obtain a first set of IP configuration parameters. The station thereafter exchanges data via the first access point using the first set of IP configuration parameters. The station performs handoff from the first access point to a second access point and performs IP configuration after the handoff. While the IP configuration is in progress, the station continues to exchange data via the second access point using the first set of IP configuration parameters. This avoids interruption in IP connectivity. After completing the IP configuration, the station either (i) continues to exchange data using the first set of IP configuration parameters if new parameters are not obtained or (ii) exchanges data using a second set of IP configuration parameters if obtained.

Abstract: Techniques for selecting a radio interface for an application are described. A terminal identifies locally-addressable and globally-addressable wireless networks among wireless networks available to the terminal. Radio interfaces supported by the terminal may be prioritized based on the locally-addressable and globally-addressable wireless networks, information obtained for the application, the application type, etc. Different applications may have different radio interface preferences or requirements, which may be considered in prioritizing the radio interfaces. A suitable radio interface may be selected for the application based on the prioritized radio interfaces. WLAN interface may be selected for the application if (a) the WLAN interface is preferred and any WLAN is acceptable to the application or (b) a globally-addressable WLAN is available. A WLAN interface may be selected for the application if a globally-addressable WLAN is not available.

Abstract: Techniques for performing WLAN system scanning and selection are described. A terminal performs multiple iterations of scan to detect for WLAN systems. A scan list containing at least one WLAN system to detect for is initially determined. For each scan iteration, a scan type may be selected from among the supported scan types. The selected scan type may indicate passive scan or active scan, frequency channels to scan, etc. A scan may be performed based on the selected scan type. Signal strength measurements are obtained for access points received during the scan and used to identify detected access points. After all scan iterations are completed, candidates access points are identified based on the scan results, e.g., based on the signal strength measurements for the detected access points and a detection threshold. The best candidate access point may be selected for association by the terminal.

Abstract: Techniques to efficiently search for a WLAN are described. A terminal receives country information from a wireless wide area network (WWAN), which may be a cellular network or a broadcast network. This country information may be a Mobile Country Code (MCC) that is broadcast by the WWAN. The MCC identifies the country in which the WWAN is deployed. The terminal then performs active scan for a WLAN based on the country information received from the WWAN. For the active scan, the terminal determines a frequency channel and a transmit power level based on the country information. The terminal then transmits a probe request on the frequency channel and at the transmit power level determined based on the country information. The terminal may perform passive scan and/or active scan in accordance with a scan setting.

Abstract: The present invention is directed to the use of concatenatable Point-To-MultiPoint (PTMP) broadcast messages for displaying display messages, and in particular long display messages requiring two or more PTMP broadcast messages, on personal cellular telecommunications devices. The present invention is achieved by the provision of a pseudo-header including a display message identifier, a PTMP broadcast message field for specifying the number P?1 of PTMP broadcast messages to transport an entire display message, and a PTMP broadcast message counter Q=(1, 2, . . . , P?1, P) for specifying the location of a PTMP broadcast message in that sequence. A pseudo-header may alternatively enable concatenation of two or more macromessages into a supermacromessage.

Abstract: A test system emulates the analog processing portion of a communication device and adjusts input signals based on distortions specified by a user and control signals generated by a baseband processing portion of the communication device. The distortions can be specified in terms of the baseband. One or more of the control signals can be bypassed to investigate the effect of each of the control signals alone, or in various combinations. An operator interface can be provided that allows the user to set up and conduct the tests, and monitor the results.

Abstract: A cellular system, in which frequency channels are allocated among transceivers which transmit to sectors of a cell, in which adjacent frequencies do not appear in adjacent sectors within the cell. A series of consecutive frequency channels is allocated to these transceivers, sequentially and alternately between opposing pairs of vertical sectors. Allocation is started from a first pair, and continued, each time, to the next pair which is adjacent to its preceding pair in clockwise or counterclockwise direction. Optionally, at least one frequency channel from the series of frequency channels is skipped, each time before continuing to allocate frequency channels to the next pair. By doing so, adjacent frequency channels are not allocated to adjacent sectors, and adjacent frequency channels do not appear in adjacent sectors even after moving allocated frequency channels from a sector to each of its adjacent sectors.
