Abstract
For a user terminal connected to one of cache devices distributed in a network and receiving contents, terminal access information including terminal address information about the user terminal and identification information of the cache device is stored and managed. If a content retransmission request message of the user terminal is detected at other cache device, this is regarded as a handover of the user terminal. This allows a simple detection of handover that occurs during content transmission.
