Abstract: In a reselection method and terminal for a PS connected state, when a network side changes a cell reselection parameter or when an intra-system cell handover occurs, a SIB3 delivered by the network side is read, and a SIB6 and/or SIB7 is read, signal strength measurement is performed on an LTE frequency point and an inter-system frequency point, and when requirements of a first threshold and an inter-system reselection threshold are satisfied, a cell reselection operation is performed, which overcomes a defect that an inter-system cell reselection operation cannot be performed on a conventional terminal even though the quality of an LTE signal is very poor when the terminal is set to an LTE only mode, and brings better service experience to a user.
