Abstract: The disclosure provides routing methods and apparatuses. One example method includes that a first node receives a data packet. The first node determines a Backhaul Adaptation Protocol (BAP) header in the data packet, where the BAP header includes a BAP address of a destination node of the data packet and first information. The first information is used to determine whether the BAP header includes a routing path identifier of the data packet. The first node sends the data packet including the BAP header to the destination node based on the BAP header.

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: A terminal device camps on a first cell in an idle state or an inactive state. The terminal device measures the first cell based on a first non-cell defining synchronization signal/physical broadcast channel block (NCD-SSB) frequency, and measures a second cell based on the first NCD-SSB frequency and/or a cell defining synchronization signal/physical broadcast channel block (CD-SSB) frequency. The terminal device performs cell reselection based on a measurement result of the first cell and a measurement result of the second cell.

Abstract: This application provides a communication method. In the method, a first node receives a first radio resource control (RRC) reconfiguration message from a first donor node through a second node. After the first node receives the first RRC reconfiguration message from the second node, the first node receives first indication information from the second node. When the first node determines, based on the first indication information, that the first RRC reconfiguration message becomes effective, the first node establishes an RRC connection to a second donor node based on the first RRC reconfiguration message. In the method, the first node and the second node are nodes in a group that performs group handover, the group handover is a cross-donor node group handover, the second node is a head node or the second node is connected to a head node, and the second node is a parent node of the first node.

Abstract: Embodiments of this application relates to a communication method and a related device. In an example, a device receives a first data packet in a first network segment, the first data packet comprises a first backhaul adaptation protocol (BAP) routing identity, and the first BAP routing identity is used for transmission of the first data packet in the first network segment. The device further obtains a first correspondence. In response to determining that the first correspondence comprises the first BAP routing identity in the first data packet, the device determines that the first data packet meets a preset condition. In response to that the first data packet meets the preset condition, the device replaces the first BAP routing identity in the first data packet with a second BAP routing identity according to the first correspondence, to obtain a second data packet.

Abstract: This application discloses a routing method and an apparatus. The method and the apparatus may be used in a multi-hop communication scenario, and may also be used in another scenario. Particularly, the method and the apparatus are used for implementing routing between an AN device and remote UE in the multi-hop communication scenario. In the method, a relay terminal on a communication link may determine a transmission object by using route indication information of a data packet, or the route indication information and a target device identifier that are of the data packet, to transmit data carried in the data packet to the transmission object. In the method, routing transmission of the data packet may be guided by using route guide information, to ensure that the routing between the AN device and the remote UE can be implemented in the multi-hop communication scenario.

Abstract: Embodiments of this application provide a lossless data transmission communication method, apparatus, and system. The method includes: A first network node determines a first data packet. A destination node of the first data packet is a third network node or a security gateway on the third network node side. The third network node is a source donor node or a source donor node central unit (CU) of the first network node. The first network node sends the first data packet to a second network node. The second network node is a target donor node distributed unit DU of the first network node. According to the method, a data packet loss in a topology update process of the first network node can be avoided, and service continuity can be ensured.

Abstract: Embodiments of this application disclose a configuration method. A donor CU may configure a mapping rule of a data packet in advance, and then send the mapping rule to a donor DU. The donor DU maps, based on the mapping rule, a subsequently received data packet to a corresponding RLC channel for transmission. In a method in the embodiments of this application, the donor DU may configure mapping rules of two mapping processes for the donor CU. In the 1st mapping process, one or more mapping fields are first determined based on a value of one or more fields (where these fields are referred to as reference fields below for ease of description) in the data packet. In the 2nd mapping process, the RLC channel is determined based on a value of the one or more mapping fields.
