The invention, which relates to the communication network field, provides a network planning method and apparatus. The method comprises the following steps that: a wireless utilization rate and telephone traffic of each cell are obtained; when the wireless utilization rate of a target cell is larger than a wireless utilization rate threshold and the telephone traffic of the target cell is larger than a telephone traffic threshold, if the carrier frequency number of the base station where the target cell is located does not reach a carrier frequency upper limit, the carrier waves of the base station where the target cell is located are increased; and when the wireless utilization rate of the target cell is larger than the wireless utilization rate threshold and the telephone traffic of the target cell is larger than the telephone traffic threshold, if the carrier frequency number of the base station where the target cell is located reaches the carrier frequency upper limit, a new base station is added. With the method and apparatus, problems existing in the cell can be diagnosed and reasonable planning can be carried out, thereby improving the service quality of the cell. In addition, the whole scheme can be implemented automatically without the need to invest manpower, thereby improving the network planning efficiency.
