The invention discloses an emergency communication
system and method, and belongs to the field of emergency communication. The emergency communication method comprises the following steps of: acquiring a link performance parameter of a
satellite communication link associated with an adjacent
station node; based on the state information and the
satellite communication link state of the local
station node, executing at least one of the following scheduling operations on the service data: determining a first
transmission performance index for transmitting data through the
satellite communication link of the local
station node, determining a first
transmission performance index of a composite path from a
wireless ad hoc network to the adjacent station node based on the state information, determining a second
transmission performance index of a composite path from the
wireless ad hoc network to the adjacent station node and transmitting data through a satellite communication link of the adjacent station node based on the state information, and selecting a forwarding path according to a comparison result of the first transmission
performance index and the second transmission
performance index; or, when the flow of the data to be transmitted meets the preset
bandwidth aggregation condition, dividing the data to be transmitted into the first data part and the second data part.
