application-based business policy. If a Wan line is unavailable or cannot meet the required performance requirements, the policy-based multi-path technology automatically and transparently transfers the application transmission stream to other available WAN links, ensure that the application transmission stream continues to be transmitted effectively and reliably. Reduces the risk of line migration Policy-based multi-path technology allows users to use low-cost Wan transmission technology (such

4.1 Cellular System The cellular system is the most widely used land-based public mobile system.Information System. In the cellular system, the coverage area is generally divided into multiple residential areas similar to the honeycomb. A fixed base station is set up in each cell to provide users with access and information forwarding services. Between mobile users and between mobile users andNon-mobile users must communicate with each other through base stations. Base Stations are generally
