摘要： This application discloses an information transmission method in a communication system. According to the method, a master base station sends a request message to a secondary base station for requesting to transfer one or more flows from the master base station to the secondary base station for transmission to a terminal device. The request message carries one or both of identification information of each flow, and information of a data radio bearer (DRB) associated with each flow. The master base station receives a response message from the secondary base station, indicating whether each of the one or more flows is admitted or rejected by the secondary base station. Based on the identification information of the flows, DRBs are mapped to the flows. QoS management of information transmission is more refined, and requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.

摘要： A handover processing method includes obtaining, by a relay station, information, where the information is used for determining whether a mobility management entity (MME) of a user equipment is in a mobility management entity pool (MME pool) to which a neighboring eNB belongs; and determining, by the relay station, that an X2 interface between a serving eNB of the relay station and the neighboring eNB cannot be used for handover if the MME of the user equipment is not in the MME pool to which the neighboring eNB belongs. The foregoing solutions enable the relay station to initiate a correct handover procedure.

摘要： A wireless backhaul method, including: a wireless backhaul device generates a first F1AP message, maps the first F1AP message to a signaling-plane bearer of an LTE Uu interface, and sends the first F1AP message to a primary base station of the wireless backhaul device via the signaling-plane bearer of the LTE Uu interface. The primary base station obtains the first F1AP message via the signaling-plane bearer of the LTE Uu interface, encapsulates the first F1AP message into a first X2AP message, and sends the first X2AP message to a secondary base station of the wireless backhaul device. The secondary base station receives the first X2AP message and obtains the first F1AP message based on the first X2AP message.

摘要： The present disclosure relates to integrated access and backhaul (IAB) node dual connectivity setup methods and communication apparatus. In one example method, a first IAB node sets up a first F1 interface with a primary donor node of the first IAB node. The first IAB node obtains an internet protocol (IP) address anchored at a secondary donor node connected to the first IAB node and/or configuration information of a serving cell, of the first IAB node, belonging to the secondary donor node. The first IAB node sends, to the secondary donor node, a request for setting up a second F1 interface with the secondary donor node, where the request includes the configuration information of the serving cell, of the first IAB node, belonging to the secondary donor node.

摘要： This application relates to the field of communication technologies, and provides a communication method, apparatus, and system. In the method, a source donor node receives a measurement report from an IAB node through a source parent node, and determines, based on the measurement report, to hand over the IAB node from the source parent node to a target parent node. The source donor node sends configuration information to the IAB node through the source parent node. In a process in which the IAB node is handed over from the source parent node to the target parent node, the IAB node sends uplink data to a target donor node by using the configuration information through the target parent node. The configuration information includes: a routing configuration and/or a bearer mapping configuration. The uplink data includes uplink user plane data and/or uplink control plane data.
