Abstract: Example communication methods, apparatus, storage media are described. In one example method, a first node obtains a backhaul adaptation protocol (BAP) routing identifier of a data packet and a topology type indicator of a topology that the data packet needs to pass through. The first node determines a source internet protocol (IP) address based on the BAP routing identifier, the topology type indicator, and a correspondence between a topology type and an IP address.

Abstract: 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.

Abstract: Embodiments of this disclosure provide a communication method, and an associated communication apparatus, medium, and chip. In a communication method, a target access network device receives first information, where the first information indicates a relationship between a first network slice in a first network and a second network slice in a second network, and the first network is different from the second network. The target access network device performs access control from a terminal device to the target access network device based on at least the first information. In this manner, in embodiments of this disclosure, the target access network device can perform access control on the terminal device during cross-network access, to reduce an access latency, reduce a service interruption problem caused by session rejection of the terminal device, and ensure service continuity of the terminal device.

Abstract: A communication method and apparatus, and a computer-readable storage medium are provided. A first access network device sends, to a first relay device, first indication information indicating whether access of a mobile relay device is allowed. When the first relay device is a mobile relay device, the first relay device sends an access request to a second access network device that allows access of a mobile relay device, so that a mobile relay device initiates an access request to an access network device that allows access of a mobile relay device, ensuring normal access of the mobile relay device.

Abstract: An inter-distributed-unit (distributed unit, DU) communication method and a related apparatus are provided. The method includes: A first DU receives data of a terminal from a central unit (central unit, CU). The first DU processes the data by using a media access control (media access control, MAC) entity scheduling function specific to the terminal, to obtain a physical layer transmission data stream. The first DU sends the physical layer transmission data stream to a second DU. In the method provided in this application, because a MAC entity of the first DU is used to uniformly schedule the physical layer transmission data stream, the first DU and the second DU do not need to exchange a large amount of layer 2 (layer 2, L2) parameter information, so that information transmission overheads can be reduced.
