1. A method, comprising:
establishing, by a first radio access network device, a first connection with a terminal;
sending, by a core network device, a first quality of service (QoS) parameter to the first radio access network device;
sending, by the first radio access network device, to a second radio access network device, a second QoS parameter based on the first QoS parameter;
receiving, by the second radio access network device, the second QoS parameter;
establishing, by the second radio access network device, according to the second QoS parameter, a second connection between the terminal and the second radio access network device; and
receiving, by the second radio access network device, an establishment response message for the second connection from the terminal directly or via the first radio access network device;
wherein the first connection between the first radio access network device and the terminal is kept after the second connection between the terminal and the second radio access network device is established.
