A method, terminal, and system for cell reselection are disclosed. The method includes: a terminal obtains a dedicated priority list from a first system; and performs cell reselection according to the dedicated priority list when the terminal camps on a cell of a second system. The corresponding terminal and system are also provided in other embodiments of the invention. According to an embodiment of the invention, the terminal performs cell reselection by using the dedicated priority list obtained from the first system so as to free the second system from establishing the dedicated priority list. Problems in the prior arts that establishment of the dedicated priority list causes too much increased signaling and too high costs for network upgrade are solved.
