摘要： 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.

摘要： 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

摘要： 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.

摘要： An access terminal scans for nearby access points and maintains a candidate list of access point with which the access terminal may associate in the event the access terminal's communication with its current access point deteriorates for some reason. This search procedure may be performed in a proactive manner whereby the access terminal repeatedly performs scans and updates its list of candidate access points when it is powered on. In some aspects, the search procedure used by the access terminal may be based on a state of the wireless device. In addition, different states of the access terminal may be associated with different optimization criteria.

摘要： This disclosure describes techniques for establishing a PPP data session between a user terminal (UT) and an Interworking Function (IWF). The process involves establishing a PPP2 link with the IWF in response to detecting a mobile IP data session request from the UT, detecting a PPP1 link with the UT in response to the PPP2 link being established, detecting that a PPP2 link failure has occurred, and reconfiguring at least one of the WCD and the UT to an initial state.

摘要： Techniques for performing system selection based on a usage model that uses “access strings”, “profiles”, and “activation strings” are described. Access strings are defined for wireless data services and provide a highly intuitive user interface. Each access string is associated with one or more profiles. Each profile includes various parameters needed to establish a specific data call. Each profile is further associated with an activation string that contains connection information for the data call. System selection is performed in two parts. In the first part, a wireless user views access strings for available data services, selects the access string for the desired data service, and returns the selected access string. In the second part, the wireless device selects a profile for a system most suited to provide the desired data service, from among all profiles associated with the selected access string.
