Detailed Signaling Description and API

Installation and User Guide: Airgo Access Point 269

After the user is redirected to the ELPS, the server can redirect the user’s browser to the originally

requested URL, or start a status/tracking window to inform the user of their time on-line.

User Initiated Disconnect

Figure 2 illustrates the flow of the signaling for a user initiated disconnect. The user typically will

have a status browser window open that includes a log out button.

Figure 190: User initiated Disconnect Request Sequence

The log out takes the user’s browser to the ELPS. At the ELPS a redirected URL sends the user’s

browser back to the AP. The redirected URL includes all parameters required to disconnect the

station.
