Embodiment

[0024] Such as figure 1 As shown, a thin AP redundant access control method in active / standby mode is applied to a wireless network (Intranet) within an enterprise, and the topology of the wireless network is as follows figure 1 As shown, it includes an AC and two thin APs connected to the AC. In this method, one AP is used as the master AP (Master AP) to transmit radio frequency signals to provide Wi-Fi access, and the other AP is used as the standby AP (StandbyAP) , usually in a power-saving sleep state, turn off the RF signal transmission signal in IEEE802.11a / b / g mode, and when the main AP fails, it will replace the main AP to transmit RF signals to provide Wi-Fi access.

[0025] The standby AP periodically detects the online status information of the primary AP by exchanging heartbeat information with the primary AP. The standby AP sends the heartbeat information Keep_Alive to the primary AP, and the primary AP returns a feedback message Keep_Alive_ACK to the standby AP a...

Abstract

The invention relates to a lightweight access point (AP) redundancy access control method of an active standby mode. The method is applied to a wireless network inside an enterprise. The wireless network comprises an AC and two lightweight APs which are connected with the AC, one AP in the method is used as a main AP, a radio frequency signal is transmitted, the other AP is used as an auxiliary AP and in electricity-saving dormant state, the radio-frequency signal is not transmitted, and the auxiliary AP cyclically detects working condition information of the main AP. If the working state of the main AP working is normal, the auxiliary AP continues to be in an electricity-saving dormant state; if the working state of the main AP is not normal, the auxiliary AP is activated and replaces the main AP to transmit the radio-frequency signal until the working state of the main AP is detected to be recovered to be normal. Compared with the prior art, the lightweight AP redundancy access control method of the active standby mode can keep same received signal strength indication, radio-frequency coverage and data rate at any time. When the main AP and the auxiliary AP are switched, network access continuity of quality of service (QoS), signal strength and the like can be ensured.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a thin AP redundant access control method adopting an active standby mode. Background technique [0002] At present, WLAN based on thin AP (centralized wireless access point) is becoming more and more popular in enterprises. In important places such as conference rooms, operating rooms, and on-site broadcasting rooms, the wireless connection between devices and APs must be guaranteed not to be disconnected. However, the AP may not be able to provide normal services due to power failure, network cable disconnection, or hardware damage. Therefore, it is very important to provide a redundant mobile AP solution. If one AP breaks down, another AP can still provide the same QoS Wi-Fi signal coverage, which is an important service reliability requirement. [0003] The problems in the current solution are that the signal strength, antenna coverage, data transmission rate, etc. ca...
