摘要

The present invention relates to a transmission method and system for groupcast message and a storage medium accessible by electronic devices applicable to a first electronic device transmitting a groupcast message to a plurality of remote second electronic devices. The method comprises steps of: acquiring a piece of communication quality information for each said second electronic device and each said piece of communication quality information representing the connection quality between each said second electronic device and nearby devices; the first electronic device selecting one of the plurality of second electronic devices as a broadcast transmitter according to the plurality pieces of communication quality information; the first electronic device transmitting the groupcast message to the broadcast transmitter; and the broadcast transmitter transmitting a broadcast message to the plurality of second electronic devices. Thereby, transmission of a groupcast message to the second electronic devices can be ensured without adding extra transmission cost.
