An embodiment of this application provides a communication method. The method includes: A second central unit control plane (CU-CP) receives context information from a first CU-CP, where the context information includes a context of a distributed unit (DU) and a context of a first central unit user plane (CU-UP). The context information is used by the second CU-CP to communicate with the DU and the first CU-UP. The second CU-CP receives a first message, and communicates with the DU and the first CU-UP based on the first message through a communication interface. According to the communication method provided in this application, a backup CU-CP can be provided for the first CU-CP, to reduce service interruption and improve system robustness.
