Abstract: The present disclosure is directed to a D2D data transfer method, and user equipment and a network device that use the method. In one method, user equipment determines a logical channel used for to-be-transmitted Device to Device (D2D) data. The user equipment determines a logical channel group corresponding to the logical channel. The user equipment reports, to a network device, a D2D data volume of the logical channel group for the user equipment. The user equipment sends, on a D2D resource that is allocated by the network device to the user equipment according to the D2D data volume, the to-be-transmitted D2D data to another user equipment by using the determined logical channel.

Abstract: A cell handover method and a device are provided, so that a target eNB uses a current serving small node as a user plane serving node after a UE is handed over. The UE and uses the target eNB as a control plane serving node after the handover. The method includes receiving a handover request acknowledgment sent by the target eNB; and sending offloading configuration information of the current serving small node to the current serving small node, and sending RRC reconfiguration information of the UE to the UE, so that offloading configuration is performed separately by the current serving small node and the UE. According to the application, a problem that in a cell handover process, a transmission resource required for transmission increases and a delay is relatively great is avoided, because the current serving small node forwards a large amount of data to the target eNB.

Abstract: 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.

Abstract: This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.
