Abstract
The FILS Discovery frame has been proposed as a minimal indication for STAs carrying out passive scanning on information on the AP.
An outline of the Access Network Options frame is provided.
It is suggested that the Access Network Options frame, with a possible addition, be considered for mandatory inclusion in the FILS Discovery Frame.

Background
The FILS Discovery Frame is intended to provide enough information for a non-AP STA to make a decision on whether to:
Proceed immediately to initiate Association
Decide to de-select this AP and move on
To decide it is worthwhile looking at the Beacon.

4. Access Network Options Field
July 2012
Access Network Options Field
Bit 4 is the Internet field. The AP or mesh STA sets this field to 1 if the network provides connectivity to the Internet
Bit 5 is the Additional Step Required for Access (ASRA) field. It is set to 1 by the AP to indicate that the network requires a further step for access.
Bit 6 is the ESR (emergency services reachable) field. It is set to 1 by the AP or mesh STA to indicate that
emergency services are reachable through the AP
Bit 7 is the UESA (unauthenticated emergency service accessible) field. When set to 0, this field indicates that no unauthenticated emergency services are reachable through this AP

Add Security ?
Note that bits 6 to 13 are reserved.
It is suggested that one bit is used for
Open / secure say 0 = Open security

Discussion
The information in the Access Network Options field appears to be directly compatible with the objectives of the FILS Discovery frame.
It is only 2 Bytes
The addition of the “Secure Bit” need not be confined to a FILS AP

Motion
Add to the Specification Framework Document the following:
“The FILS Discovery Fame shall include the Access Network Options field. In addition, the possible inclusion of ‘Secure or Open’ indication be included (using a reserved field).”
