Abstract: Provided are a network handover method and apparatus, a device, and a storage medium. The method is applied to a first communication node and includes: a handover required message is sent to a core network, where the handover required message carries reference information of UE context at a source side; and a handover control message sent by the core network is received, where the handover control message carries information for maintaining the UE context at the source side, and the information for maintaining the UE context at the source side is used for instructing a network node at the source side not to release resources used by a UE, and the information for maintaining the UE context at the source side is determined by the reference information of the UE context at the source side.

Abstract: Provided are a data radio bearer control method, device, and system for a multi-connection system. The data radio bearer control method for a multi-connection system comprises: establishing a split protocol data unit session comprising M quality of service flows, the M quality of service flows being respectively established on N radio access network nodes, wherein one of the N radio access network nodes is a master node, and N−1 radio access network nodes other than the master node among the N radio access network nodes are secondary nodes, M and N are positive integers, and M≥2 and N≥2; and establishing a default data radio bearer for the split protocol data unit session, and configuring the default data radio bearer on any one of the radio access network nodes.
