Abstract: PROBLEM TO BE SOLVED: To provide a method for dynamically selecting a radio TCP proxy position in a cable-radio composite network environment. SOLUTION: When a plurality of radio TCP proxies exist in the routine route of the cable-radio composite network environment, the movement property of a mobile host is measured with a network resident time by the radio TCP proxy of an applicable network whenever the mobile host is moved to another network (step 310). In the case of high movement property in the mobile host, the high-order radio TCP proxy on the routing route is activated (steps 312-324). When movement property is low, the radio TCP proxy of the newly moved network is activated (steps 312-318).
