The access method comprises: a first core network device determines that a terminal that has been connected or attempts to connect the first core network device needs to be handed over to a second core network device, the first core network device and the second core network device communicate with the terminal by using a same access network device; and the first core network device sends a core network repositioning request message to the second core network device, the core network repositioning request message being used for instructing the second core network device to establish a connection with the terminal. In this way, the terminal can rapidly roll back to the second core network device, and establishes a service connection with the second core network device, thereby reducing the service failure probability and the service delay.
