Abstract

Embodiments of the present disclosure relate to handover. In response to receiving a request for handover of the second device from the third device to the first device, the first device sends to the third device an indication for a radio bearer of the second device to change from a separate bearer terminated in the fourth device to a primary cell group bearer terminated in the first device, and the second equipment is dual-connected with the third equipment and the fourth equipment. The first device receives, from a third device, a transmission status of data associated with the radio bearer.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of telecommunications, and in particular, relate to an apparatus, method, apparatus, and computer-readable medium for switching between master nodes. Background technique [0002] In New Radio (NR), a terminal device can operate in Multi-Radio Dual Connectivity (MR-DC) mode, where the terminal device can connect to a node or network device of a Multi-Radio Access Technology (RAT). MR-DC may include E-UTRA-NR Dual Connectivity (EN-DC). In EN-DC, a terminal device may have one connection with an eNodeB (eNB) acting as a master node (MN) and another connection with an en-gNB acting as a secondary node (SN). [0003] A terminal device may have multiple primary cell group (MCG) bearers terminated in the eNB and multiple split radio bearers terminated in the en-gNB. Via the inter-primary node handover procedure, the terminal device can be handed over to the target eNB without secondary nod...
