摘要： This invention provides an apparatus that associates a location where a terminal uses communication or travel route in use of the communication, with a connection destination of the terminal. The apparatus includes a communication log analyzer that aggregates communication logs collected by network apparatuses that constitute the mobile network and analyzes it. The communication log analyzer estimates travel route of the terminal connected the network using: log information generated by a base station to be connected to the terminal at the time of starting the connection, log information generated by a base station to be connected to the terminal at the time of a handover of the connection, and log information generated by a base station connected to the terminal at the time of detaching the connection.
