Network selection method for power 4G cellular wireless communication

The invention relates to the field of communication, in particular to a network selection method and system for power 4G cellular wireless communication. The method specifically comprises the steps that a user actively triggers a network searching instruction in the electric power main control equipment, a cellular communication unit feeds back the network searching instruction to a selected optimal signal operator in the electric power main control equipment after receiving the network searching instruction of the electric power main control equipment, and the optimal signal operator is used for carrying out data interactive transmission in the electric power main control equipment. According to the method, network operator selection of cellular wireless communication is optimized and controlled in a power use scene, so that the communication quality and the communication success rate of cellular wireless communication in power equipment are improved, meanwhile, the operator with the optimal signal in a spec
