Against the background of a surge in software-defined network (SDN) as well as urgent demands for LTE-WIFI internetworking and IPv6 network integration, the paper integrates LTE mobile telecommunication technology, wireless local area network and 5G (the fifth generation mobile communication system) into one, in an attempt to complete routing, distribution, and transmission of different radio frequency signals (i.e.LTE, WIFI) on the SDN basis.As a result, large-area coverage of LTE-WIFI network signals is realized in a way that meeting the demands of reliability, safety, flexibility and extendibility for mobile internet.What is more, different complementary wireless telecommunication systems are closed combined with each other.Through the use of SDN integration technology, the paper designs network integration architecture of IP-LTE mobile internet and WIFI, and also studies on the application of SDN-based IP optical integration network, which has broad prospects.
