Patent ID: 10070359

Abstract:
Per-station realm lists are dynamically generating per-station for hot spot connections to access points by roaming stations. A query for a list of realms is received from a roaming station when connecting to a hot spot. Using an MAC address or other station identity, a list of available realms narrowed to a subset of per-station realms sent to the station. Narrowing is performed on-the-fly with respect to at least one aspects. A last N realms are retrieved from a database record searched by MAC address. The list is further narrowed by removing realms that are inaccessible or otherwise recently shown to have bad link quality. Additional ranking factors can narrow or rearrange the realm list based on financial agreements, popularity, trends, and the like. A selection from the list of realms is received from the station. The access point then authenticates the station with the selected realm. If successful, data traffic concerning the station can be forwarded through the hot spot on behalf of the selected realm.
