<p>The present invention aims to relay data by using two kinds of communication systems for continuous and smooth transferring of data in accordance with a connection state. A mobile communication terminal 2 includes: a mobile communication unit 121 that connects to a mobile communication network NW to download data therethrough, a short-range communication unit 122 that transmits the data downloaded to opposing equipment through short-range communication, a communication management unit 123 that detects a state of connection with the opposing equipment, a data storage unit 126 that temporarily stores the data downloaded, and a data management unit 125 that successively hands over the data temporarily stored to the short-range communication unit 122. In the case that the state of connection indicates an out-of-service-area state, the data storage unit 126 additionally stores data being downloaded by the mobile communication unit 121. In the case that the state of connection has changed from the out-of-service-area state to a normal state, the data management unit 125 hands over not-yet-transmitted data blocks stored by the data storage unit 126 to the short-range communication unit 122.</p> |
