1. A method implemented by a terminal, wherein the method comprises:
before entering a target section on a first preset path, determining a target communication system from at least two communication systems based on prestored network status information of the at least two communication systems in the target section, wherein the prestored network status information comprises an identifier of a first cell that is in continuous nodes and that is covered by a first network of a first operator, wherein each node is a section of a preset length on the first preset path, and wherein determining the target communication system comprises:
weighting, based on a coverage area, a second cell that is of a second network of a second operator to which each of the at least two communication systems belongs and that is in the target section to obtain weighted coverage area values that are of networks of different operators and that are in the target section; and
determining, from the at least two communication systems, a first communication system corresponding to a third network that has a largest weighted coverage area value and that is of the networks as the target communication system;
switching from the first communication system to the target communication system before or when entering the target section; and
performing communication using the target communication system.
