A cell signal strength prediction method, comprising: receiving (S201, S208), by user equipment, a measurement configuration, and measuring signal strength of a serving cell; recording, by the user equipment, the signal strength of the serving cell within a first preset time period; determining, by the user equipment based on the signal strength of the serving cell within the first preset time period, whether the signal strength of the serving cell is falling; and if the signal strength of the serving cell is falling, predicting, by the user equipment, signal strength of the serving cell that is at a second preset time; wherein the method further comprises: measuring, by the user equipment, signal strength of a neighboring cell of the serving cell based on the measurement configuration; recording, by the user equipment, the signal strength of the neighboring cell of the serving cell within the first preset time period; determining, by the user equipment based on the signal strength of the neighboring cell of the serving cell within the first preset time period, whether the signal strength of the neighboring cell of the serving cell is increasing; and if the signal strength of the neighboring cell of the serving cell is increasing, predicting, by the user equipment, signal strength of the neighboring cell of the serving cell that is at the second preset time. receiving (S201, S208), by user equipment, a measurement configuration, and measuring signal strength of a serving cell; recording, by the user equipment, the signal strength of the serving cell within a first preset time period; determining, by the user equipment based on the signal strength of the serving cell within the first preset time period, whether the signal strength of the serving cell is falling; and if the signal strength of the serving cell is falling, predicting, by the user equipment, signal strength of the serving cell that is at a second preset time; wherein the method further comprises: measuring, by the user equipment, signal strength of a neighboring cell of the serving cell based on the measurement configuration; recording, by the user equipment, the signal strength of the neighboring cell of the serving cell within the first preset time period; determining, by the user equipment based on the signal strength of the neighboring cell of the serving cell within the first preset time period, whether the signal strength of the neighboring cell of the serving cell is increasing; and if the signal strength of the neighboring cell of the serving cell is increasing, predicting, by the user equipment, signal strength of the neighboring cell of the serving cell that is at the second preset time. measuring, by the user equipment, signal strength of a neighboring cell of the serving cell based on the measurement configuration; recording, by the user equipment, the signal strength of the neighboring cell of the serving cell within the first preset time period; determining, by the user equipment based on the signal strength of the neighboring cell of the serving cell within the first preset time period, whether the signal strength of the neighboring cell of the serving cell is increasing; and if the signal strength of the neighboring cell of the serving cell is increasing, predicting, by the user equipment, signal strength of the neighboring cell of the serving cell that is at the second preset time.
