3. doc.: IEEE 802.11-12/0394r0 Submission Use Case 1: Neighborhood Directory March 2012 Description: Jane is doing some shopping in a mall. Instead of entering stores one by one on foot to find some good deals, she receives, on her mobile device, the mall directory information (such as stores’ names and locations) as well as the special offers associated with each store. The information is broadcasted by the AP deployed by the mall operator. HuaweiSlide 3

4. doc.: IEEE 802.11-12/0394r0 Submission Use Case 1: Sequence of Events Step 1. AP broadcasts in Beacon: 1) that it is a “Mall Directory Provider”; 2) a subsequent broadcasting schedule for the directory services. Step 2. Before Jane enters the shopping mall, she has typed the key word of “shoe” via the application. Then her mobile device starts to scan for any beacon that contains advertisement information related to “shoe” and the corresponding broadcasting schedule. Step 3. When Jane enters the shopping mall, her mobile device receives a beacon that is transmitted by a “Mall Directory Provider”. Jane’s mobile device will read the beacon and find out whether it has “shoe” related information in its broadcasting schedule for the directory services. If so, according to this broadcasting schedule, her mobile device will only receive the broadcasting related to “shoe” and may remain in power-saving mode during the time of broadcasting of “non-shoe” information.

5. doc.: IEEE 802.11-12/0394r0 Submission Use Case 1: Summary of Requirements AP indicates, in the beacon, that it is an information provider and advertises the categories of information that it provides and the corresponding broadcasting schedule. AP further broadcasts details of one or more different categories of information at a time, based on the broadcasting schedule. A STA can selectively receive a particular category of information that it wishes to received, maybe based on the inputs from the end user. Need to specify a list of service/information categories and related attributes. Need to extend the Beacon frame to advertise service information. March 2012 HuaweiSlide 5

6. doc.: IEEE 802.11-12/0394r0 Submission Use Case 2: Discovery services before association March 2012 Description: John enters a hotel and wants to find a WLAN that supports a 3D printer. There are 5 WLANs in the hotel, but not obviously what services they provide and the parameters of their services, such as price, service time, admission control etc. John sends out request of “printer” service, then APs of these WLAN response his request. Finally, John choose a WLAN to do his print task. HuaweiSlide 6

7. doc.: IEEE 802.11-12/0394r0 Submission Use Case 2: Sequence of Events Step 1. John subscribed “printer” via the application. Currently, his mobile device is not associated with any AP. Hence, the mobile device sends out e.g. Probe Request with “printer” service in it. Step 2. APs of these WLANs receive the Probe Request, check local services, and if supporting such service, send Probe Response with service information of “local printer”. Step 3. John receives printer information of existing WLANs and chooses one according to his preference. March 2012 HuaweiSlide 7

8. doc.: IEEE 802.11-12/0394r0 Submission Use Case 2: Summary of Requirements STA indicates, in the probe request, the information or service that it is looking for, maybe with the inputs of the end user via an application AP receives this scanning and check local services information, and if having such information or supporting such service, sends probe response with information of the service or information that it has or supports. STA receives information of existing WLANs and based on user’s preference (e.g. time, charge, quality etc.) choose one to associate with. Need to specify a list of service/information categories and related attributes. Need to extend the Probe Req/Rep frames to carry service information. March 2012 HuaweiSlide 8
