Wireless system with wired fault self-restoring function and self-restoring method thereof

Abstract

The invention relates to a wireless network system, and discloses a wireless system with a wired fault self-restoring function, wherein the wireless system settles a problem of normal Internet logging-on incapability by terminals in the coverage range of a wireless access point (AP) after a wired connection between the wireless AP and a wireless access point controller (AC) is disconnected in traditional technology. The wireless system comprises an AC router and a plurality of wireless APs. Each wireless AP is connected with the AC router in a wired manner. After an address is automatically acquired, a wireless configuration parameter is acquired through a CAPWAP connection; wireless configuration of a local terminal is finished and furthermore the wireless configuration parameter is stored. The wireless network system is also used for testing the communication state between the wireless AP and the AC router periodically, thereby determining whether the wired connection between the wireless AP and the AC router is normal. If an abnormity occurs in the wired connection, an adjacent wireless AP is automatically searched, and furthermore a certain available wireless AP is connected through the stored wireless configuration parameter in a wireless manner. Furthermore the invention discloses a corresponding wired fault self-restoring method which is applicable for an (AC+AP) architecture network system.

Description

technical field [0001] The invention relates to a wireless network system, in particular to a self-recovery technology when a wired failure occurs in the wireless network system. Background technique [0002] With the development and application of the Internet and information technology, especially the popularity of notebook computers, smart phones, and tablet computers, wireless network technology has become the most important access technology for edge networks. [0003] CAPWAP (RFC5415) This technology makes a complete specification for the wireless control protocol. The entire network architecture is composed of AC (Wireless Controller) and AP (Wireless Access Point), and its networking form is as follows: figure 1 As shown, the CAPWAP encrypted tunnel is used between the AC and the wireless AP to forward all the data of the wireless AP to the AC for unified processing. Due to the introduction of AC, it has the following technical advantages compared with ordinary SOH...
