Abstract: A method for improving a paging response speed of a user equipment (UE), includes: camping, by the UE on a first cell of a first network, the UE being in an RRC connected state; when a first preset condition is met, sending, by an access network device, a first message to the UE, the first message being used to indicate the UE to enter an RRC inactive state; recording, by the access network device, that the UE is in an RRC inactive state; and in response to the first message that is received, entering, by the UE, the RRC inactive state; and when a second preset condition is met, camping, by the UE, on a second cell of the first network, where the UE is in an RRC inactive state, and the first cell and the second cell are the same or different.
