Abstract: The present application relates to an RRC connection release method, and a related device and system. The RRC connection release method comprises: a terminal, rather than a network device, determines whether service transmission of the terminal ends; after the terminal determines that the service transmission ends, the terminal sends to the network device an MAC CE for an RRC connection release request; after receiving the MAC CE for the RRC connection release request, the network device can determine to send to the terminal an RRC connection release message or an RRC release message to initiate an RRC connection release process of the terminal. In this way, the terminal in an RRC connection state can enter an RRC idle state or an RRC inactive state as quickly as possible after the service transmission ends, rather than entering the RRC idle state or the RRC inactive state after a period of time after a timer times out, thereby facilitating reducing the power consumption of the terminal.
