4. doc.: IEEE 802.11-07/0446r0 Submission March 2007 Canpolat et alSlide 4 Background and Problem Description Today as the WLAN air interface is currently defined, before accessing the network, a STA can only tell if the network security is enabled or not. When a STA tries to select a WLAN network there is no way of telling which network is private, public, enterprise or hotspot and their authorization mechanisms. Example use case: –Client powers up in a downtown urban setting, scans the environment and detects 100 SSIDs. Client must sort the list into those SSIDs to process further and those to discard –Important for client to conserve battery energy during sorting process, so a fast sorting mechanism is beneficial –After first-pass fast sort, client can make targeted GAS queries to determine services available, online enrolment possibility, etc. To enable seamless handover, the client needs to know whether to: –Programmatically launch a browser or HTTP client: even if SSID is open auth, web auth may still be employed denying service until login completed (this indication is helpful when WLAN does not support state-1 access to 802.21-IS). –Programmatically launch VPN if needed: VPN may be needed on public networks, but not on home enterprise network.

E.g., corporation, university. A enterprise private network with guest accessYes & NoAuthorized guest users only Public free networkYes & No Participants users only. E.g., museum, Portland downtown network, IEEE conference. Commercial networkYes & No Typical designation for hotspot or mesh network. May require user’s acceptance of provider’s terms. E.g., Coffee shop, airport, hotel networks.

Advertise the WLAN type and enrolment method. The STAs can listen to it prior to WLAN association in state-1 and make use of hotspot configuration information when making network selection. After the STA detects that the WLAN type, it may perform the proper steps to establish network connection and enrolment.
