Data sharing method and data processing system

摘要

A data sharing method includes detecting by a first data processing apparatus that is among multiple data processing apparatuses that share data, any one among a shortage of available memory, a change in remaining battery power, a change in a relative positional distance of the first data processing apparatus to a second data processing apparatus that is among the data processing apparatuses, a change in a communication speed of communication with the second data processing apparatus, and an interruption of communication with the second data processing apparatus; and transmitting by the first data processing apparatus to a third data processing apparatus that is among the data processing apparatuses, a shared portion of the data saved in the first data processing apparatus.

1. A data sharing method comprising:
first transmitting, by a second data processing apparatus from among a plurality of data processing apparatuses that share data, a data to a first data processing apparatus from among the plurality of data processing apparatuses; deleting, by the second data processing apparatus, the data from a memory of the second data processing apparatus; detecting, by the first data processing apparatus, any one among a shortage of available memory of the first data processing apparatus, a change in remaining battery power of the first data processing apparatus, a change in a relative positional distance of the first data processing apparatus to the second data processing apparatus, a change in a communication speed of communication with the second data processing apparatus, and an interruption of communication with the second data processing apparatus; and second transmitting, by the first data processing apparatus to a third data processing apparatus from among the plurality of data processing apparatuses, the data transmitted from the second data processing apparatus and saved in the first data processing apparatus.
