Embodiment Construction

[0018] The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0019] figure 1 It is a flowchart of the steps of the present invention, specifically:

[0020] Step 101, preparing to start WDS automatic configuration and connection;

[0021] Step 102, the access point continuously broadcasts the WDS probe frame containing the MAC address of the access point. For details, see figure 2 ;

[0022] Step 103, monitor the WDS detection frame from other access points, and analyze the MAC address to establish a data link, see the detailed process image 3 ;

[0023] Step 104, detect the access point where the gateway of WDS and the DHCP server are located, and configure the IP addresses of other access points, see the detailed process Figure 4 ;

[0024] Step 105, judge whether the network works, if so, then enter step 106, otherwise, proceed to step 104;

[0025] Step 106, end.

Abstract

The invention discloses a method for automatically constructing a wireless distribution system, which is used for automatically constructing the wireless distribution system under the circumstance that a plurality of access points do not need user configuration and comprises the steps as follows: the access points continuously broadcast detection frames of the wireless distribution system (WDS) that contain MAC address of the access points; WDS detection frames from other access points are monitored and MAC address is resolved to establish data links; the access points are checked to confirm if the access points are gateways, if so, the access points are configured to be a DHCP server, otherwise, a local area network is checked to confirm if the DHCP server exists in the local area network; if the DHCP server exist in the local area network, a DHCP client is started; if the DHCP server does not exist in the local area network, the access points are configured as the DHCP server; at the same time, that whether other DHCP servers are accessed into the network is detected; if so, the DHCP server of the access points is shut off and the DHCP client is started. The method of the invention can realize the connection of the wireless distribution system, without manual setting by the user.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for automatically configuring and connecting a wireless distributed system. Background technique [0002] At present, the most common wireless local area network architecture is that the local area network includes an access point (AccessPoint, AP) and multiple wireless terminals. On the one hand, the AP can establish a connection with the wired network through a cable connection; The connection realizes the communication between the wireless terminals, and the communication between the wireless terminal and the wired network. A set of wireless terminals within an AP and its signal coverage area is called a basic service set (Basic Service Set, BSS). [0003] In the wireless network protocol defined by 802.11, the Wireless Distributed System (Wireless Distributed System, WDS) is used to realize the interconnection between the above-mentioned BSSs, thereby expanding...
