METHOD AND APPARATUS FOR DISCOVERY OF LOCATION CONTEXT IDENTIFIERS BASED ON APPROXIMATE LOCATION

摘要

As part of a localized positioning solution, a mobile device may transmit a request message to a server to obtain information about location contexts near the mobile device. In response, the server may, in some implementations, transmit a response message back to the mobile device that identifies a list of nearby LCIs and an area that encompasses these LCIs. The mobile device may store the returned LCI information and the returned area information in corresponding databases for later use. In some implementations, time limits may be placed on the returned area information after which the information is deemed stale.

主权项

1. A machine implemented method for managing location context identifier (LCI) requests received from a mobile device, comprising:
receiving a request message for one or more LCIs from said mobile device, said request message comprising location information; determining a region associated with said location information; and transmitting a response message to said mobile device in response to said request message that indicates an unavailability of LCIs in said region at least partially in response to determining that there are no known LCIs within said region associated with said location information.
