Captive portal systems, methods, and devices

Abstract

Embodiments of the present technology provide out-of-band captive portal devices, networks, and methods. An example of a method includes executing a redirection of a client request for network access to a captive portal login, initiating an association between the wireless controller and the client, receiving authentication credentials of client from the captive portal login, negotiating a change of authorization with a wireless controller in accordance with RFC 5176 protocol, wherein the controller includes a mapping to a captive portal Internet Protocol (IP) address, and redirecting the client to a URL specified in the client request for network access.

Description

Background technique [0001] When a client tries to access a WiFi hotspot, for example at a coffee shop or an airport, the client typically receives a pop-up login screen that requires the client to enter authentication credentials. If the user is not logged into the wireless network or even attempts to log in to the wireless network, client devices within range of the wireless network's access point may transmit repeated authentication requests, thereby generating network congestion. As a result, clients actively coupled to wireless terminals may experience latency while connecting to the wireless network, particularly in public places where there may be a large number of client devices (eg, stadiums, shopping malls, concerts, etc.). Contents of the invention [0002] According to some embodiments, the techniques of the present invention may involve a method comprising the steps of: (a) performing a redirection to a captive portal login on a client request for network access...
