DATA SHARING SYSTEM |
摘要 |
Provided is a data sharing system in which data are shared between a plurality of communication terminals capable of wirelessly transmitting and receiving a communication message to and from each other. Each communication terminal determines whether or not the own communication terminal is a specified terminal. Each communication terminal, in case of it is determined that the own communication terminal is a specified terminal, transmits a holding list that lists information about data that the own communication terminal holds, to another communication terminal through use of a communication message. Each communication terminal, when receiving a holding list from another communication terminal, transmits and receives communication messages to and from the other communication terminal that is a source of the holding list that does not match the holding list of the own communication terminal so as to share data with each other. |

1. A data sharing system in which data are shared between a plurality of communication terminals capable of wirelessly transmitting and receiving a communication message to and from each other, wherein
each of the communication terminals comprises: a communication unit that transmits and receives the communication message to and from another of the communication terminals; a data storage unit that stores one or more pieces of data; a specified terminal determination unit that determines whether or not the own communication terminal is a specified terminal; a holding list transmission unit that transmits, in case of the own communication terminal is the specified terminal, a holding list that lists information about the data stored in the data storage unit to another of the communication terminals through use of the communication message; and a data exchange unit that receives the holding list from another of the communication terminals, and transmits and receives the communication message to and from the other communication terminals that is a source of the holding list that does not match the holding list of the own communication terminal so as to share data with each other. |
