The invention provides a wave beam selection method and apparatus, and relates to the technical field of communication. The delay of initial access flow of user equipment can be shortened. The methodcomprises the following steps: selecting a millimeter waves base station for providing service for the user equipment according to the position information of the user equipment; respectively inputting the position information of the user equipment in a plurality of n classifiers corresponding to the millimeter waves base station, and obtaining the wave beam having the highest votes in the sendingwave beams of the millimeter waves base station to serve as a first target wave beam according to judgment results output by the plurality of n classifiers; and sending indication information used for indicating the first target wave beam selected by the user equipment for the millimeter waves base station to the millimeter waves base station. Each n classifier is used for judging the category towhich a wave beam corresponding to the position information of the user equipment belongs in n categories of the n classifier, the n categories correspond to n sending wave beams of the millimeter waves base station, and n is an integer greater than or equal to 2. The wave beam selection method and apparatus provided by the invention are applied to wave beam selection.
