    Abstract: A first device may communicate via a first wireless interface (WI) and a second WI, with the second WI operating at a relatively higher power level than the first WI. The first device may receive a scan notification corresponding to wireless scanning performed by a second device. The first device may subsequently perform wireless scanning using the second WI in response to the scan notification indicating that the first device is within effective communication range of a third device. The first device may receive the scan notification over a wireless connection established between the first device and the second device using the first WI. The first device may transmit filter information to the second device, the filter information indicating when, and for which scans the first device is to receive scan notifications. The first device may also activate the second WI and use the second WI to perform ranging and/or control operations associated with the third device.

    Abstract: Methods and apparatus for providing primary transport service discovery information over one or more alternate transports that are not normally associated with the primary transport services. In one embodiment, the primary transport comprises a first wireless interface (e.g., Bluetooth), and the alternate transport comprises a second wireless interface (e.g., WiFi or WiMAX). Service profile information relating to the primary transport is broadcast to other users over the alternate transport in a more efficient and streamlined manner than that available on the primary transport. The other users store this service profile information so that it can be subsequently accessed for service profile discovery of the transmitting device by those other devices, thereby obviating subsequent transfer of the data over any transport (primary or alternate).
