ENABLING DEVICES TO DISCOVER SERVICES THROUGH A NETWORK CONTROLLER OR GROUP OWNER

摘要

Techniques are described that permit a STA to determine if one or more particular services are available from other devices in a particular network, without having to first associate with that network. This may be accomplished by having the network controller obtain and maintain a list of services provided by all of the associated devices in the network. An unassociated device may provide a list of services it is looking for in a Probe Request. In the Probe Response, the network controller can provide a list of the requested services that are actually available from devices in its network. This permits the unassociated device to determine if this network has the services it needs, without having to first become associated with that network.

a processor, a memory, and a radio, wherein the device is configured to
communicate a probe request containing a first list of services being sought in a network; andcommunicate a probe response containing a second list of services that are both in the first list and available in the network.
