Abstract: Example multi-connectivity communication methods and apparatus are described. In one example method, an access network device of a first network determines to use an access network device of a second network to perform data splitting for data of UE. Then, the access network device of the first network sends first splitting configuration information to the UE and sends second splitting configuration information to the access network device of the second network. The first splitting configuration information is used to notify the UE that the access network device of the second network is to split to-be-split data of the UE. The second splitting configuration information is used to instruct the access network device of the second network to split the to-be-split data of the UE.

Abstract: A link failure report transmission method and apparatus are provided. When a link between a terminal and a first radio access network device fails, and a master radio access network device of the first radio access network device is handed over, the terminal sends a first link failure report to a second radio access network device, so that the second radio access network device forwards the first link failure report to a third radio access network device, and the third radio access network device sends the first link failure report to the first radio access network device. In this way, the first radio access network device can perform parameter adjustment based on the first link failure report.
