Method and device for frequency priority adjustment

The invention provides a method and a device for frequency priority adjustment. The method comprises steps that network access selection parameters of a first cell are determined by a base station; the network access selection parameters are sent by the base station to the UE in the first cell, and the network access selection parameters are used for making the UE in the first cell adjust the stored frequency priority configuration information. According to the method and the device for frequency priority adjustment, through adjusting the priority configuration of the UE, the UE is enabled to carry out cell reselection according to priority after adjustment, and thereby loads of cells can be reduced.
