Abstract
A local device broadcasts a service advertisement in a wireless network, where the service advertisement includes one or more service identifiers (IDs) identifying one or more services being advertised and an availability schedule of the local device. Optionally, the local device reduces power to at least a portion of the local device and wakes up at a time according to the availability schedule. The local device listens in the wireless network according to the availability schedule of the local device. In response to a service request received from a remote device during the availability window, the local device transmits a service response to the remote device. The service request includes one or more service IDs identifying one or more services being inquired by the remote device and the service response includes detailed information associated with one or more services identified by the one or more service IDs.
