Abstract

A method of data communication based on internetwork can make the User of radio LAN and the User of cable LAN interview cable WAN system resource first, if cable WAN system resource can be interviewed, or interview to radio WAN system resource through radio WAN network card module, and then to interview Internet resource indirectly, if cable WAN system resource can not be interviewed by using defined mobile bridge equipment, i.e both the user of radio LAN and the User of cable LAN can interview network data resource at most conditions.

Description

technical field

[0001] The invention relates to a method and system for enabling mutual data communication between communication networks. Background technique

[0002] At present, it is more and more common to use different platform technologies and networks of different standards to combine and communicate with each other. Solutions are in full swing. Moreover, considering the direction of technological development, it is also the trend to combine various networks for interconnection and intercommunication.

[0003] In the current technical situation, wireless LAN users and wired LAN users can access the resources in the network or roam between other wireless LAN systems, and access the resources of wired WAN through the control function of the access controller, so that the wireless LAN Users or wired LAN users can access wired WAN resources and LAN resources in areas where wired WAN systems are wired. However, when wireless LAN users arrive in areas where wiring is di...

Embodiment Construction

[0054] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0055] figure 1 As shown, the overall system of the present invention includes a wireless WAN system 3 , a wired WAN system 2 , a wired LAN system and a wireless LAN system 1 . The users of the wired LAN system and the wireless LAN system 1 can access the network resources of the wired WAN system 2 and the wireless WAN system 3 through the routing and gateway functions of the mobile network bridge 4. When they can access the wired WAN system 2, the mobile network Bridge 4 preferentially connects users of wired LAN system and wireless LAN system 1 to wired WAN system 2, so that users of wired LAN system and wireless LAN system 1 can directly access wired WAN system resources; where wired WAN system 2 cannot be wired Or when the wired WAN system 2 breaks down and cannot be accessed, the mobile bridge 4 connects the users of the wired LAN s...
