The captive portal environment exists where there is only a single available communication service that is available to the user. An example of a captive portal environment is on board an aircraft in flight, where the passengers have no access to any communication services, other than the aircraft resident wireless Local Area Network. The Restricted LAN Internet Access System functions in the aircraft to grant the user a temporary Internet session so they can download a prerequisite application from the Internet to make use of an application/service resident on the Restricted LAN in the aircraft.
