<P>PROBLEM TO BE SOLVED: To provide a proxy delivery server which can reduce traffic delay, make more efficient use of network resources, and maintain the continuity of service being provided to a mobile terminal even upon relocation of mobility anchor. <P>SOLUTION: In a mobile communication system including a mobility anchor which provides mobility to a terminal, a proxy delivery server (600b) for relaying contents to be delivered from a service provision server (500) to a terminal (400), upon request for mobility anchor relocation, acquires context information relating to relay of contents from another proxy delivery server (600a), which is relaying the contents to be delivered to the terminal. The proxy delivery server (600b) uses the information to reproduce a session with the terminal which was maintained between the other proxy delivery server and the terminal for content delivery, and forwards the contents to be delivered to the terminal via the reproduced session using location data of the contents already delivered from the other proxy delivery server to the terminal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
