User access method based on SDN (Software Defined Network) and Hotspot2.0 for use under novel network architecture

Abstract

The invention discloses a user access method based on an SDN (Software Defined Network) and Hotspot2.0 for use under novel network architecture, and belongs to the field of wireless communications. The user access method comprises the following specific steps that: users judge whether a current Wi-Fi (Wireless Fidelity) network supports Hotspot2.0 or not; if so, the users send requests to an SDN global controller through AP (Access Point) ends; the SDN global controller issues current Wi-Fi network information to the AP ends, and the AP ends resolve frames, package the resolved frames into an ANQP (Access Network Query Protocol) frame format, and issue the packaged frames to the users; the users configure a network filtering strategy according to demands, and filter the current Wi-Fi network information; the users judge whether the network of which the current Wi-Fi network information is filtered still supports Hotspot2.0 or not, and if so, the users automatically connect to the Wi-Fi network for authentication; otherwise, the users access the Wi-Fi network in a conventional way; the SDN global controller verifies identity information through RADIUS; and user terminals are connected to the Internet after successful verification. The user access method has the advantages that an SDN technology is combined with a Hotspot2.0 technology, so that the problem of information sources of newly-added information elements in the Hotspot2.0 is solved. Meanwhile, the SDN has higher controllability specific to the networks, and seamless fusion between a honeycomb network and the Wi-Fi network is ensured better.

Description

technical field [0001] The invention belongs to the field of wireless communication, relates to the design of Wi-Fi network architecture in wireless communication, in particular to a user access method under the new network architecture based on SDN and Hotspot2.0. Background technique [0002] The continued popularity of smartphones, along with the use of wearable devices, will lead to a substantial increase in mobile data usage. According to a forecast report released by network equipment giant Cisco, by 2019, global wireless data traffic will increase to 10 times the current level. Cisco's "Visual Networking Index" study predicts that global wireless data traffic reached 30 billion gigabytes last year. Cisco analysts believe that if this growth trend continues, wireless data traffic on the global Internet will reach 292 billion gigabytes by 2019. A key driver of the dramatic growth in wireless data traffic is the raw growth of mobile subscribers, currently estimated at ...
