Problems solved by technology

For an ESS network that performs access and resource optimization, the randomness of access increases the difficulty of optimization, which is not conducive to the balance of ESS network load
In addition, the randomness of access also reduces the switching efficiency of stations in the ESS network

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0032] figure 1 It is the application environment diagram of the preferred embodiment of the present invention.

[0033] 101 is an extended service group, and an ESS is composed of multiple BSSs interconnected through a distributed system.

[0034] 102 is a distributed system, and related basic service groups can form an extended service group through the distributed system, and the distributed system can be wired or wireless.

[0035] 103 and 104 are BSS, referring to a set of wireless workstations controlled by a single equivalent function. In the BSS, the infrastructure mode and the ad hoc network mode can be adopted.

[0036] 105 and 106 are APs (Access Points, access points), and each AP can be identified by a basic service set identification number (BSSID). An AP can access multiple sites.

[0037] 107, 108, 109, 110, 111, and 112 a...

Abstract

The invention discloses a method for realizing handover and connection in a wireless local area network. Under the different circumstances that a station and an access point are establishing a connection or having already established a connection according to the existing wireless local area network protocol, different handover and connection processes are performed by using a handover instruction message, It makes the handover target of the station in the ESS network clear, and the handover efficiency is high, and the passive handover process of the station in the ESS network does not require user participation, effectively and quickly guides the user to access other recommended access points, and improves the quality of user access. At the same time, the phenomenon of frequent switching is reduced, making the ESS network more efficient when implementing site access optimization.

Description

technical field [0001] The invention relates to a wireless local area network system in the field of communication, in particular to a method for switching connections in the wireless local area network. Background technique [0002] WLAN (Wireless Local Area Network) refers to the application of wireless communication technology to interconnect computer equipment to form a network system that can communicate with each other and realize resource sharing. In a WLAN network environment, an ESS (Extended Service Set) is composed of multiple BSSs (Basic Service Sets) interconnected through a distributed system, and this distributed system can be wired or wireless. The access point acts as an interface to each individual basic service group within the extended service group system. The station selects the access point by extending the ESSID (service set identification number), and different access points in the same ESS can be distinguished by the BSSID (basic service set identi...
