Embodiment Construction

[0023] refer to figure 1 , various embodiments generally relate to a wireless network 100 including an out-of-band external captive portal device 105 . In some embodiments, wireless network 100 also generally includes clients 110 , access point 115 , a RADIUS server (also referred to as a remote access server), and WLAN controller 125 . Other examples of wireless networks that may be used to practice aspects of the inventive techniques are at Figures 11A-13B , which will be described in more detail later.

[0024] Client 110 includes any device configured to couple with access point 115 . Non-limiting examples of clients include cell phones, smartphones, laptops, tablets, machine-to-machine devices such as smart sensors, or other similar devices as will be known to those skilled in the art.

[0025] Access point 115 includes any device that allows clients to connect to a wired or wireless network using a wireless communication protocol. A non-limiting example of access po...

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...
