Problems solved by technology

[0006] 1. Increased the complexity of joining
In the example shown in Figure 1, the security level of the BSS1 network is relatively high. If STA3 wants to join BSS1, it must also increase its own security level. However, the high-level security method usually requires hardware support. level of security, it will cause STA3 to be unable to join BSS1
[0007] 2. Reduced network securi

Example Embodiment

[0032] The specific implementation process of the present invention will be further described below in conjunction with the accompanying drawings:

[0033] The design concept of the present invention is to modify the device access method based on the IEEE 802.11 protocol to enable a single device, including AP (access point) or STA (station), to support multiple wireless local area networks at the same time. Each supported wireless local area network is independent of each other, and the operation of the device in each wireless local area network is also independent of each other. At the same time, the present invention makes corresponding modifications to other relevant parts of the IEEE 802.11 protocol.

[0034] According to different functions, wireless LAN devices can be divided into STA (site) and AP (access point). STA (station) refers to any device that includes a MAC (Media Access Layer) interface and a PHY (Physical Layer) interface that comply with the wireless local are...

Abstract

The invention discloses a method of single equipment can support several wireless local area networks that comprise following steps: conjunction, data communication, network maintenance, releasing conjunction; the first network is conjunct with the equipment, based on request of logical chain layer, the current channel of the first network can be conjunct for the second time, the third time until the n times; at the same time, during course of transmitting data in data communication, the logical chain layer sends data request, and section which expresses network address is added into the original words; during course of receiving data in data communication, forming data chain layer that which section of network address received belongs to. The invention strengthens the safety and agility of wireless local area networks, and expands the application occasion.

Description

technical field [0001] The invention relates to a wireless local area network access method, in particular to a method for a single device to simultaneously support multiple wireless local area networks. Background technique [0002] Wireless local area network is the product of the combination of computer network and wireless communication technology in the 1990s. It provides an effective method of using wireless multiple access channels to support communication between computers, and provides mobile, personal and multimedia applications for communication. potential means. The concept of "wireless interconnection" was first proposed by IT enterprises, mainly referring to the wireless connection of network communication. With the development of 3C (household appliances, communications, and computers) integration trends, the interconnection and interoperability between home appliances has become the focus of major companies, and it is called one of the future development dir...
