Abstract
A first access network device sends first configuration information to a terminal device, where the first configuration information includes multipath configuration information and a first trigger condition, the multipath configuration information includes configuration information of a plurality of second transmission paths, and each second transmission path includes a transmission link between the terminal device and one second access network device and an interface link between the first access network device and the second access network device. When a radio link between the terminal device and the first access network device meets the first trigger condition, the terminal device activates the multipath configuration information, and transmits a same RRC message to the first access network device by using a first transmission path and at least one second target transmission path. Accordingly, a same RRC message is transmitted by using a plurality of transmission paths, thereby improving RRC message reliability.
