For the built base station power consumption model, as the model only aims at a certain specific type of base station, in order to build the whole network base station power consumption model, the model is subjected to migration learning, so that the whole network base station power consumption model is obtained. By using the migration learning method, the knowledge migration of the model can be realized, the requirement on training data can be reduced, and the efficiency, accuracy and generalization capability of model construction are higher.

In the embodiment of the present application, the modeling of the whole network base station may be performed for a certain target area (city, a certain area of city, etc., villages and towns, etc.), or may be performed for a whole range formed by a plurality of target areas in a larger range.
In an embodiment of the present application, the types of base stations are categorized according to the POIs in which the base stations are located, including but not limited to, business centers, highways, metropolitan villages, residential communities, suburban roads, industrial parks, schools, subways, and the like. Of course, other classification methods are also possible, and the setting can be performed according to the needs of the user.
In the application, the existing base station power consumption modeling method is considered to model by analyzing the power consumption of the base station antenna unit and the baseband unit, so that the geographic position of the base station and the traffic of different types of services are not considered. The difference in geographical location may have an effect on the propagation of the signal and thus on the power consumption of the antenna unit. For example, in urban dense areas, signal propagation can be affected by blocking and multipath effects, resulting in antenna elements requiring more power to maintain coverage and signal quality. And the traffic (such as voice communication, video stream, etc.) of different types of services has different load requirements on the baseband unit, so that the power consumption of the baseband unit can be influenced. Therefore, in order to improve the accuracy of the model, the application selects the geographic position of the base station and the traffic of different types of services as parameters. Meanwhile, in the transfer learning process, the pre-training and the fine-tuning are adopted, and as the pre-training process adopts the original data set, only the current base station data set with smaller data size is adopted in the fine-tuning process, so that the training difficulty and complexity are greatly reduced. And the modeling efficiency of the base station power consumption model is improved.
The above embodiments are only for illustrating the technical solution of the present application, and are not limiting; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application.
