Abstract: A paging method, a base station and a UE are provided. The paging method includes: receiving, by a UE in an inactive state, a paging message for determining a paging type, the paging message being transmitted from a base station, the paging type including an access network paging initiated by an access network or a core network paging initiated by a core network; determining, by the UE, the paging type corresponding to the paging message; and when the paging type corresponding to the paging message is the core network paging, updating, by the UE, each of states of a NAS and a RRC layer for the UE into an idle state, and responding to, by the UE, the paging message.
