SERVICE DISCOVERY USING A LOCATION DATABASE

摘要

Methods, systems and computer readable media for building and using a location database for service discovery are described. In some implementations, the method can include detecting, at a location engine, a connection between a client and a new service within a wireless network, and receiving an RF fingerprint of the client. The method can also include determining a location of the client and the new service based on the RF fingerprint, and querying a location database using the RF fingerprint as a key. The method can further include determining whether a location database entry exists corresponding to the RF fingerprint. The method can also include, when there is no database entry corresponding to the RF fingerprint, adding a new record to the database corresponding to the RF fingerprint and the new service. The method can further include, when there is database entry corresponding to the RF fingerprint, computing a rank for the new service and updating the database entry corresponding to the RF fingerprint corresponding to the RF fingerprint.

1. A method comprising:
detecting, at a location engine, a connection between a client and a new service within a wireless network; receiving an RF fingerprint of the client; determining a location of the client and the new service based on the RF fingerprint; querying a location database using the RF fingerprint as a key; determining whether a location database entry exists corresponding to the RF fingerprint; when there is no database entry corresponding to the RF fingerprint, adding a new record to the database corresponding to the RF fingerprint and the new service; and when there is database entry corresponding to the RF fingerprint, computing a rank for the new service and updating the database entry corresponding to the RF fingerprint corresponding to the RF fingerprint.
