Abstract
An extension to the Access Network Query Protocol (ANQP) protocol allows stations (STAs) to discover multiple APs via a single ANQP request/response exchange. A STA can send a single ANQP request message to request information for multiple APs, e.g., two or more neighboring APs. The receiving AP may retrieve discovery information for one or more neighboring APs, and send an AP response message including the retrieved discovery information to the requesting STA. The ANQP request message identify the multiple APs for which discovery information is sought, and may specify which information is being requested for that corresponding AP.
