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.

Abstract: Example transmission rate control methods and apparatus are described. One example method includes obtaining a user equipment aggregate maximum bit rate (UE-AMBR) by a master base station. The master base station determines, based on the UE-AMBR, a first UE-AMBR used for the master base station and a second UE-AMBR used for a secondary base station. The master base station sends the second UE-AMBR to the secondary base station, and sends instruction information used to instruct the secondary base station to control data splitting for the master base station to the secondary base station. In this application, a transmission rate between each base station and a UE is controlled by allocating a UE-AMBR.

Abstract: A configuration method is provided in a communications system. The communications system includes a master node and a secondary node that jointly provide a service for a terminal. The method includes: the secondary node generates configuration information for a signaling radio bearer (SRB), where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal; and sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal, thereby improving efficiency in radio resource management on the secondary node.

Abstract: This application relates to the field of communications technologies, and discloses example redirection methods and apparatuses to ensure that a call drop does not occur after UE is redirected. One example method includes determining, by a base station, that a redirection operation needs to be performed on user equipment UE, and then instructing a core network to reserve a guaranteed bit rate (GBR) bearer or a voice service bearer that is corresponding to the UE. The UE is then instructed to reserve the GBR bearer or the voice service bearer that is corresponding to the UE. After the UE is redirected to a new base station, the voice service bearer of the UE is reserved on a UE side.
