Abstract:
Methods, apparatuses and systems directed to providing location services in a wireless network. According to one implementation of the present invention, the wireless network infrastructure provides high-accuracy location information via location services to wireless clients. In one embodiment, during an advertisement phase, a location server provides a list of available location services to wireless clients via a central controller. In another embodiment, during a presentation phase, a driver of the wireless client presents the available location services to one or more applications of the wireless client. In another embodiment, during a request phase, the driver transmits a location service request to the central controller, which passes the location service request to the location server.
