doc.: IEEE /0067r0 Submission Jan 2014 Ping FANG, HuaweiSlide 3 Background In 13/501r0, a architecture with service registration and service discovery is registered. Per the meeting discussion, the registration can be done in MAC layer or upper layer after association. In 13/796r0, the procedure on how a STA discovers necessary service information before association is described with a high level 2-step service discovery procedure proposed. In 13/796r1, more details on service indication are further discussed. In 13/893r0, different service hash values proposed to be carried in service discovery request and response with public action frame for privacy and security. In 13/1403r0, Service indication from AP, network discovery and detailed service information query are described.

Further Discussion
1. At what level of service information, should proxy build and keep?a) Just service name/service ID + URLb) Above all + Description Document
2. If proxy also keeps description document, should proxy fully support upper layer service discovery protocol?
3. For PAD, to what level of service name can be expect? Printer, UPnP Printer, urn:schemas-upnp-org:service:PrintBasic:1?
