A Generic Routing Encapsulation (GRE) bearing method, apparatus and system are provided. In the transmission and bearing of GRE frames, multiplexing frame header information of the GRE frames is obtained by inquiring mapping of the GRE frames; then the GRE frames that meet a predetermined multiplexing condition are set in payloads of one outer Internet Protocol (IP) frame according to the obtained multiplexing frame header information of the GRE frames. In this way, for data frames with small payloads, unnecessary encapsulation overheads are reduced, and the transmission efficiency of the data frames is improved. Thus, the network bandwidth resources are saved, and the system transmission performance is improved.
