1. A cell measurement method comprising:
sending, by a first access network device, first measurement control information to a terminal device through a first serving cell, wherein the first measurement control information indicates the terminal device to measure quality of a downlink reference signal of a virtual cell, a center frequency of a downlink reference signal of the first serving cell is the same as a center frequency of the downlink reference signal of the virtual cell, a frequency range of the virtual cell is comprised in a frequency range of a second serving cell, and the frequency range of the second serving cell overlaps with a frequency range of the first serving cell;
receiving, by the first access network device, a first measurement report from the terminal device, wherein the first measurement report indicates the quality of the downlink reference signal of the virtual cell; and
migrating, by the first access network device, the terminal device to a third serving cell based on the quality of the downlink reference signal of the virtual cell being higher than quality of the downlink reference signal of the first serving cell, wherein
a standard of the second serving cell is different from a standard of the first serving cell, or the standard of the second serving cell is the same as the standard of the first serving cell and a center frequency of a downlink reference signal of the second serving cell is different from the center frequency of the downlink reference signal of the first serving cell;
the virtual cell and the second serving cell are cells of the first access network device, or the virtual cell and the second serving cell are cells of a second access network device; and
a standard of the third serving cell is the same as the standard of the first serving cell, and a center frequency of a downlink reference signal of the third serving cell is different from the center frequency of the downlink reference signal of the first serving cell, or a standard of the third serving cell is different from the standard of the first serving cell.
