Abstract: The present disclosure discloses example communication methods and apparatuses. One example method includes obtaining physical random access channel (PRACH) configuration information of one or more cells by a first central unit (CU). The PRACH configuration information of the one or more cells is sent from the first CU to a first distributed unit (DU).

Abstract: A first access network device sends, to a terminal device, an application layer measurement configuration used to indicate the terminal device to perform quality of experience measurement and collection on a first service. The application layer measurement configuration includes a type of the first service and an indicator of quality of experience of the first service. The type of the first service includes one or more of Augmented Reality (AR), Virtual Reality (VR), and 5th Generation Media Streaming (5GMS). The first access network device receives an application layer measurement report from the terminal device. The application layer measurement report includes the type of the first service and a value corresponding to the indicator of quality of experience of the first service.

Abstract: A cell selection method, including receiving a broadcast message, where the broadcast message includes indication information, the indication information indicates to camp on a first capacity component carrier (CCC) cell, the first CCC cell is a CCC cell associated with a BCC cell, and the BCC cell is a BCC cell that is found by a terminal device and that satisfies a cell selection criterion, and determining, based on the indication information and the cell selection criterion, whether to camp on the first CCC cell. The indication information indicates the to terminal device to select an appropriate cell to camp on.

Abstract: This application provides an access network device selection method and an apparatus. In the method, the terminal device may indicate, to a DNS through one or more of first indication information, second indication information, and at least one GIN, whether the terminal device needs to support external authentication. Therefore, when selecting the non-3GPP access network device for the terminal device, the DNS may consider one or more of the first indication information, the second indication information, and the at least one GIN, to select the proper non-3GPP access network device for the terminal device based on the indication of the terminal device. For example, when the terminal device supports external authentication or needs to support external authentication, the DNS may select, for the terminal device, a non-3GPP access network device capable of performing external authentication.

Abstract: An access network device obtains first information, where the access network device supports a 3rd generation partnership project 3GPP access technology; the access network device establishes a user plane connection to a first terminal device based on the first information; and the access network device obtains user plane data of the first terminal device via the user plane connection, and sends the user plane data to a first fixed network gateway device.
