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 emobidment, 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.

Abstract: In some embodiments, a method for replacing an existing Differentiated Services Code point (DSCP) value with a new DSCP value, or augmenting an existing DSCP value with a new DSCP value is described. In an example embodiment, a new DSCP value is generated, added to the value field of a protocol session and transmitted to another device. The protocol session may be SIP, SDP, RTSP or some other suitable protocol. In an example embodiment, a system is described wherein a first device is operatively coupled to a second device in a peer to peer configuration, wherein communications between the first and second device is controlled by a third device.
