This invention discloses a hard switching power control method to control the emit power of UE oven better when carrying out different or same frequency hard switching without adding new radio links so as to ensure the stable variance of the emit power after the UE is switched to a new area. In this invention, TPC is a value that can be distributed before the hard switched link is synchronized or non-TP search is carried out. Different kinds of TPC are arranged flexibly to control the up rising speed of UE up power based on different radio environments.
