Mobile access controller, mobile locak area network and metropolitan area network, and access method

Abstract

The disclosed mobile access controller of mobile LAN includes mobile access control device, more than one port of mobile wide area network (WAN) and LAN. The ports of LAN are connected to users and servers inside LAN. Ports of mobile WAN are in use for implementing connection to mobile access control device and WAN. The mobile access control device includes data-sending module, data-receiving module and load balancing module. The data-sending module is in use for processing data inside LAN, and in charge for sending data to WAN. The data-receiving module is in use for processing data from WANand forwarding processed data to inside LAN. Based on actual working conditions of ports of mobile WAN, load balancing module sends and allocates data to specific port of mobile WAN. Through differentoperation manager of mobile network, the invention implements connection of WAN raises speed, reliability and stability of wireless WAN connection.

Description

technical field [0001] The invention relates to a mobile local area network, an access device and an access method, in particular to a mobile access controller, a mobile local area and wide area network and an access method. It belongs to the technical field of network communication. Background technique [0002] A local area network (Local Area Network or LAN) is a group of computers and other auxiliary devices such as printers and storage that are physically separated from each other by specific types of transmission media (such as cables, optical cables, and wireless media). Systems linked together to allow users to communicate with each other and share resources. [0003] A traditional (wired) LAN usually uses a device called a Gateway to connect the LAN to a Wide Area Network (Wide Area Network or WAN). The primary function of a traditional (wired) LAN gateway is to control the data passing through it and convert the protocol it uses. It generally has a (wired) WAN p...

Problems solved by technology

Second-and-a-half / third-generation technology can cover a larger area, thereby supporting better mobility; while WLAN has a smaller coverage area

First of all, because the wireless signal is greatly affected by the environment and is more likely to be interfered, the stability of the wireless WAN port connection is much lower than that of the traditional wired connection; in addition, compared with WLAN, the second and a half or third generation mobile communication The transmission rate of the technology is much lower, and the bandwidth is not wide enough, resulting in a serious mismatch between the upload and download rates of mobile WLAN; third, it is still difficult for a single mobile network provider to provide ubiquitous second-and-a-half-generation or third-generation mobile communications Signal coverage, including coverage of indoor, outdoor and remote areas, will also affect the range of use of mobile WLAN and the stability of the upload connection of mobile WLAN (such as in vehicles); in addition, in During operation, some wireless WAN connections seem to be connected on the surface, but they are actually dead, that is, no data is actually transmitted or only a small amount of data can be transmitted. The wireless WAN connection will participate in load balancing load distribution, but in fact it will not achieve the purpose of transmitting data
