Method and system for recovering user services at communication link change

Abstract

The invention relates to the technical field of wireless local area network processing, in particular to a method and a system for recovering user services at a communication link change. The method comprises the following steps: S1, switching a wireless access point between an escape mode state and a non-escape-mode state according to a communication link change, and setting whether to enable network access authentication states of wireless networks or not; S2, setting a state machine state of a user according to a setting result in the step S1; and S3, judging whether the user is permitted to access network resources or not. Through adoption of the method and the system, normal services of the user can be recovered more efficiently and reasonably.

Description

technical field [0001] The invention relates to the technical field of wireless local area network processing, in particular to a method and system for restoring user services when a communication link changes. Background technique [0002] Thin AP is a kind of AP (wireless access point). It generally refers to the AP device that needs to be upgraded with the cloud AC device (cloud wireless controller). The networking of AC+thin AP is the mainstream networking method commonly used at present. This method is convenient and quick to install, low in cost, flexible in layout, and easy to maintain. AC can notify and manage all APs, and can realize multiple APs, a wireless network SSID wireless roaming function, mobile office in the wireless coverage area, and the client can be on the AP. Therefore, whether it is a wireless network in an enterprise or a hotel, it basically adopts the networking mode of thin AP+AC. [0003] In the thin AP mode, the wireless AP is controlled by the...

When the communication link between the AP and the cloud AC platform (cloud wireless controller platform) is normal, the wireless AP returns to the normal non-escape mode. Therefore, when the communication link between the AP and the cloud AC changes, how to ensure wireless access The user's business has become an important consideration in the research and development of wireless APs. The current practice is to use the process of forcibly kicking out all users first to make users reconnect to the wireless access point. If the communication link between the AP and the cloud AC platform is interrupted Users on this SSID go online and offline frequently, which will seriously affect the user experience.

For example, a method and device for detecting link keep-alive between AC and AP with the publication number of 103458436B, including: setting the maximum allowable failure times of heartbeat keep-alive; Allowing the number of failures to perform the link keep-alive detection between the AC and the AP, wherein: the step of performing the link keep-alive detection between the AC and the AP through the heartbeat message and based on the maximum allowable number of failures of the heartbeat keep-alive includes: If the AC fails to receive the heartbeat keep-alive message sent by the AP within the heartbeat keep-alive period, within the range of the maximum allowable failure times of the heartbeat keep-alive, the link keep-alive detection in the heartbeat keep-alive period is cyclically carried out; Through message retransmission, and based on the heartbeat keep-alive maximum allowable failure times, the step of performing link keep-alive detection between the AC and the AP includes: by setting the heartbeat keep-alive maximum allowable failure times, and setting the maximum retransmission interval; Within the range of this maximum retransmission interval, the retransmission of the request message between the AP and the AC is performed cyclically to perform link keep-alive detection. Especially in this link structure, there may often be link changes. If the If you reconnect, the information response time will be slower and the user experience will be very poor.
