摘要： PROBLEM TO BE SOLVED: To execute content distribution for a moving node whose existing position is changed from a distribution node with high quality. SOLUTION: A cache server is arranged between a radio LAN and a cable network where a moving node may exist. The cache server is configured to distribute contents to the moving node while storing the contents from a distribution node in a buffer. The moving node, when it moves, transmits movement notification to a cache server connected to the radio LAN at the movement destination. The cache server which has received the movement notification is configured to re-transmit the contents to the moving node by acquiring the contents of the buffer from the cache server used by the moving node before moving. Thus, it is possible to improve distribution quality. COPYRIGHT: (C)2006,JPO&NCIPI
