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.

Network handover method and apparatus, device, and storage medium

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.

Data radio bearer control method, device and system for multi-connection system

Provided are a redundant session establishment method and apparatus, a radio bearer establishment method and apparatus, a node, a terminal and a medium. The redundant session establishment method includes: generating redundant user plane resource information, and transmitting the redundant user plane resource information to a master node; and establishing a redundant session corresponding to a redundant session request in a redundant user plane resource according to the redundant session request from the master node, where the redundant session request is a request generated by the master node according to the redundant user plane resource information.

Redundant session establishment method and apparatus, radio bearer establishment method and apparatus, and nodes, terminal, and medium

Method, device and computer program product for wireless communication are provided. A method includes: transmitting, by a first wireless communication node, a control message to a second wireless communication node, to control the second wireless communication node to instruct a wireless communication terminal to enter a radio resource control, RRC, inactive mode and transmitting at least one small data transmission, SDT, configuration to the wireless communication terminal.

Method, device and computer program product for wireless communication

The invention relates to the field of communication, and provides a method and a device for configuring a redundant PDU session. The method includes: obtaining first redundancy indication information for establishing or modifying the PDU session and/or a QoS flow; and configuring the redundant PDU session and/or a redundant QoS flow on a corresponding RAN node, according to the first redundancy indication information. In the present invention, establishing and modifying of a user plane multi-connectivity can be realized by obtaining the redundancy indication information for establishing or modifying the PDU session and/or the QoS flow, and configuring the redundant PDU session and/or the QoS flow to the corresponding RAN node according to the redundancy indication information.
