Abstract
This application provides method and apparatus for RRC state control. An access network device obtains RRC connected inactive state indication information of UE. When the UE leaves an RRC connected state, the access network device determines, based on the RRC connected inactive state indication information, that the UE enters an RRC connected inactive state or an RRC idle state, so that the access network device can control, based on a state of the UE, the UE to enter an appropriate RRC state, thereby reducing signaling overheads and improving system performance.
Claims21
