Techniques for optimizing selection and update of a relevant subset of Wi-Fi AP location information by a mobile client device to efficiently utilize resources

摘要

In one embodiment, techniques are provided for efficiently selecting and distributing wireless local area network (WLAN) access point (AP) data to a mobile client device. A reference database is maintained on a network server. An expected future location of the mobile client device is determined. The expected future location represents a location different than a present location of the mobile client device, which the mobile client device is expected to visit in the future. One or more tiles are transferred from the reference database to the mobile client device for a bounded geographic region that includes the expected future location. The one or more tiles are stored on the mobile client device to be available for use in satisfying one or more subsequently received requests for estimation of location of the mobile device.

1. A method comprising:
maintaining a reference database on a network server, the reference database storing WLAN AP data that includes at least locations of WLAN APs or fingerprint information for signals transmitted by WLAN APs; determining an expected future location for a mobile client device, the expected future location representing a location different than a present location of the mobile client device, the expected future location determined based on information provided by a user of the mobile client device or information provided by an application executing on the mobile client device; determining a condition of the mobile client device, the condition to include at least one of a type of the application executing on the mobile client device or a type of network connection available to the mobile client device; in response to both the determining the expected future location and the determining the condition of the mobile client device, transferring one or more tiles from the reference database to the mobile client device for a bounded geographic region that includes the expected future location; and storing the one or more tiles on the mobile client device to be available for use in satisfying one or more subsequently received requests for estimation of location of the mobile client device.
