In order to improve the efficiency of the data communication between mobile wireless communication terminals having a communication means mainly used for the wireless communication between the mobile wireless communication terminals and a wireless communication means mainly with a base station, a following terminal is used. Namely, it includes: a first communication unit used for communication with a specific base station; a second communication unit used for communication with other mobile wireless communication terminals; a storage area storing content data that can be used in the mobile wireless communication terminal and can be transmitted to other mobile wireless communication terminals; and a communication controller that obtains specific content data by searching the storage area when a request of the specific content data is accepted from a user of the mobile wireless communication terminal, transmitting a request to other mobile wireless communication terminals that can communicate via the second communication unit when the valid specific content data is not detected in the storage area, and transmitting a request to the specific base station via the first communication unit when the specific content data cannot be received from other mobile wireless communication terminals, which can communicate, within a predetermined time.
