Method for single equipment to support simultaneously plurality of wireless LAN

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...

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 security

As mentioned in 1, if the hardware of STA3 does not support high-level security methods, STA3 will not be able to join BSS1. At this time, if you still want to add STA3 to BSS1, you must lower the security level of BSS1 so that STA3 can join, and this undoubtedly reduces the security of the network, causing a great security risk

[0008] 3. Need the support of the operating system
