8. doc.: IEEE 802.11-13/0118r2 Submission January 2013 Stephen McCann, RIMSlide 8 Use Case Keywords 1 Service discovery –Ability to discover a service. –Ability to discover services including device/application capabilities within a query. –Ability to provide specific identifiers within a query (e.g. public identity or Gold/Silver/Bronze subscription indication) Specific device type discovery –Ability to discover a specific device type service and their capabilities/parameters, including as an example indications of relative cost alternatives. –Ability to discover other discovery mechanisms and protocols available within the WLAN/Network.

9. doc.: IEEE 802.11-13/0118r2 Submission January 2013 Stephen McCann, RIMSlide 9 Use Case Keywords 2 Proximity (relative to user) –Location of the user –Proximity of the services is used to filter alternative options –Other dimensions Speed of Service (time of day, duration) –Ability to determine the immediacy of a service (e.g. is it instant, delayed)

10. doc.: IEEE 802.11-13/0118r2 Submission January 2013 Stephen McCann, RIMSlide 10 Use Case Keywords 3 Network (internet, intranet) access discovery –Ability to discover services available through the network together with necessary indications/parameters for access. Determine possible shortcomings of the existing IEEE 802.11u/IEEE 802.11ai solutions. –Local AP Services / Network Services Ability to discover the proximity/locality and the availability of services. In addition to discovering services, the means of access is also required. Ability to discover a service via a walled garden.

11. doc.: IEEE 802.11-13/0118r2 Submission January 2013 Stephen McCann, RIMSlide 11 Use Case Keywords 4 (covered above) Ignore the “broadcast by AP” (not an information delivery system) Pre –association, then open access walled garden Mobility during pre-association discovery 3rd party identifiers captured by the device would form part of a query (e.g. TV ID) API required? Probe/Response mechanism Proximity
