Document Type and Number:

WIPO Patent Application WO/2014/128808

Kind Code:

A1

Abstract:

In the present invention, a communication terminal (first communication terminal) classifies a plurality of data held by the selfsame terminal into a plurality of groups, and for each group, forms a held list which is a list setting forth information of the data belonging to the group. Also, the first communication terminal transmits by means of a communication message to another communication terminal (second communication terminal) a held list selected from among the formed held lists for each group. The second communication terminal requests of the first communication terminal the data not held by the selfsame terminal among the data in the held list received from the first communication terminal. The first communication terminal transmits to the second communication terminal the requested data.
