DOCUMENT SHARING SYSTEM, AND RADIO TERMINAL AND PROGRAM IN THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a document sharing system that prevents concentration of communication access to one radio terminal and performs smooth communication without interruption even if any one radio terminal is used as an access point.SOLUTION: A document sharing system 1 defines any one of a plurality of radio terminals 11-15 belonging to a group that shares documents as an access point, and distributes a document from the access point radio terminal 11 to the other radio terminals 12-15. When each of the radio terminals 12-15 receives an acquisition request for a battery residual quantity from another radio terminal, it obtains the battery residual quantity of itself and gives notice of the battery residual quantity. The radio terminals having received the notice determines that a radio terminal 12 has the best battery state on the basis of the battery residual quantity among the radio terminals including itself, and transmits an access point switching request to the radio terminal 12 with the good battery condition if it is determined that switching of the access point is necessary.
