Distribution method and apparatus of AP addresses in WLAN

Abstract

The invention relates to a distribution method and apparatus of AP addresses in a WLAN. The method comprises the following steps: synchronizing configuration data of registered APs; receiving DHCP packets forwarded by BASs, the packets bearing attribute information of APs sending the DHCP packets; comparing the attribute information of the APs sending the DHCP packets with the attribute information in the configuration data; if the configuration data comprises the attribute information of the APs sending the DHCP packets, determining that the APs sending the DHCP packets are the registered APs, and otherwise, determining that the APs sending the DHCP packets are unregistered APs; if the APs sending the DHCP packets are the registered APs, obtaining information of ACs corresponding to the APs sending the DHCP packets from the configuration data; and distributing the addresses to the APs sending the DHCP packets, and issuing the obtained AC information. According to the invention, VLAN resources can be reduced, maintenance difficulties are lowered, the APs can be flexibly accessed to specific ACs, and the utilization rate of the ACs is improved.

Description

technical field [0001] The present disclosure relates to a WLAN (Wireless Local Area Network, wireless local area network), in particular, to a method for allocating an AP address in a WLAN network and an AP (Access Point, access point) address allocating device. Background technique [0002] Traditional wireless access points integrate multiple functions, such as physical layer, link layer, user data encryption, user authentication, QoS (Quality of Service, quality of service), security policy, user management and other applications layer functions, etc. This type of wireless access point is commonly known as a "fat" AP. It is characterized by flexible configuration, simple installation, and high cost performance, but each AP is independent of each other, there is no coordination mechanism, user terminals cannot seamlessly roam across APs, APs cannot sense each other, and cannot coordinate their transmission power. Therefore, it is not suitable for places with complex env...

Problems solved by technology

[0006] Since the BAS needs to identify the AP and the corresponding AC device according to the VLAN ID connected to the AP, the APs corresponding to different ACs need to be assigned different VLANs. Since the operator operates all services, the VLAN resources of the access network are limited. The number of VLANs allocated to WLAN services is very small, which results in a limited number of ACs that connect to the BAS, that is, the limited number of APs, resulting in limited WLAN network capacity, affecting the large-scale development of the WLAN network, and ultimately affecting the WLAN network. coverage and wireless city construction; at the same time, different ACs correspond to different AP uplink VLANs, which brings difficulties to the configuration and maintenance of the access network VLAN and BAS, increases the workload, and is prone to errors
