Abstract: This application provides a communication method. The method includes: When a radio link failure RLF occurs on a first communication device connected to a first donor network device, the first communication device performs an RLF recovery process, and connects to a second donor network device. The first communication device determines that the first donor network device and the second donor network device are different network devices. The first communication device sends first information to a second communication device, where the first information indicates the second communication device to send a radio resource control RRC re-establishment request message, or indicates the second communication device to obtain system information sent by the first communication device.

Abstract: A communication method applied to an integrated access and backhaul (IAB) system includes: a child node receives a first radio resource control (RRC) reconfiguration message from an access network device via a parent node, where the first RRC reconfiguration message includes a random access-free indication. The child node starts a timer. The child node sends a first RRC reconfiguration complete message to the access network device via the parent node. The child node receives first indication information from the parent node, where the first indication information indicates to stop the timer. The child node stops the timer.

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: A method includes: a first IAB node sets up a first RRC connection to a target IAB donor by performing RLF recovery. The first IAB node sends a first message to a second node by using an SRB 1 or an SRB 2 or the first IAB node sends a BH RLF indication to the second node. t The first IAB node sets up an RRC connection to a target IAB donor by performing RLF recovery and the second node is connected to a source IAB donor through the first IAB node. The second node may be triggered to set up an second RRC connection to the target IAB donor based on the first message or the BH RLF indication.

Abstract: A method for releasing an F1 connection is used for an IAB node. The method includes: receiving a first message from a source IAB donor node, where the first message indicates that a central unit CU of an IAB donor node connected to the IAB node changes; and releasing an F1 connection to a CU of the source IAB donor node according to the first message. Therefore, the IAB node can release the F1 connection in time based on an indication of the source IAB donor.

Abstract: Embodiments of this application provide communication method and related devices. In an example method, a first IAB-donor-central unit (CU) determines a quality of service (QoS) attribute corresponding to an F1 application protocol (F1AP) message, where an F1 interface is a communication interface between the first IAB-donor-CU and a distributed unit (DU) of an IAB-node. Then, the first IAB-donor-CU sends the F1AP message and the QoS attribute corresponding to the F1AP message to a second IAB-donor-DU.

Abstract: A communication method and a related device include in response to a first node determining that an RLF occurs on a radio link between the first node and a second node, and there is no other available path between the first node and a destination node, the first node sends first indication information to a third node. The first indication information indicates the RLF or indicates that a link recovery attempt is being made. The second node is a parent node of the first node, and the third node is a child node of the first node; or the second node is a child node of the first node, and the third node is a parent node of the first node, or a donor node connected to the first node.
