1. A method for determining signal quality information of a frequency, comprising:
obtaining, by a network device, signal quality information, of a first frequency, from a plurality of terminal devices, wherein the first frequency is a frequency used by a serving cell accessed by the plurality of terminal devices;
determining, by the network device, signal quality information of a second frequency based on the signal quality information of the first frequency and a stored first mapping relationship, wherein the second frequency is different from the first frequency, and the first mapping relationship is a mapping relationship between the signal quality information of the first frequency and the signal quality information of the second frequency, wherein the first mapping relationship is obtained by modeling sample data of the signal quality information of the first frequency and sample data of the signal quality information of the second frequency, wherein
the signal quality information of the first frequency comprises a signal quality parameter of a first neighboring cell that uses the first frequency, and the sample data of the signal quality information of the first frequency comprises the signal quality information of the first frequency measured for a plurality of times by the plurality of terminal devices that access the serving cell, and
the signal quality information of the second frequency comprises a signal quality parameter of a second neighboring cell that uses the second frequency, and the sample data of the signal quality information of the second frequency comprises the signal quality information of the second frequency measured for a plurality of times by the plurality of terminal devices that access the serving cell; and
performing at least one of the following:
determining, by the network device, spectral efficiency of the serving cell based on the signal quality information of the first frequency, load information of the first neighboring cell, and a stored second mapping relationship, wherein the second mapping relationship is a mapping relationship between the signal quality information of the first frequency and the load information of the first neighboring cell and the spectral efficiency of the serving cell; or
determining, by the network device, spectral efficiency of the second neighboring cell based on the signal quality information of the first frequency, load information of the second neighboring cell, and a stored third mapping relationship, wherein the third mapping relationship is a mapping relationship between the signal quality information of the first frequency and the load information of the second neighboring cell and the spectral efficiency of the second neighboring cell.
