Abstract

The invention discloses a D2D communication relay node selection method in an electric power communication system, and the method comprises the steps that a current terminal constructs a neighbor terminal list which comprises a plurality of neighbor terminals of the current terminal; The current terminal performs priority ranking on a plurality of neighbor terminals in the neighbor terminal list according to a predetermined strategy; When the current terminal receives the overload warning message of the current neighbor terminal, the priority of the current neighbor terminal is reduced in theneighbor terminal list according to the overload warning message, and the current neighbor terminal only sends the overload warning message to the neighbor terminal of the current neighbor terminal when the service load exceeds a load threshold; And when the current terminal needs to perform D2D communication, the neighbor terminal with the highest priority in the neighbor terminal list is selected as a relay node, and a D2D communication link is established with the relay node to perform D2D communication. The communication efficiency can be improved.
