Abstract

Provided are an address coordination method and device, a base station, a session management function (SMF) network element and a storage medium. In a handover process of a terminal from a source base station side to a target base station side, a UPF split state of a PDU session of the terminal may be determined and data transmission tunnel address coordination may be implemented, thereby enhancing flexibility of split control of the PDU session in the handover process of the terminal, preventing the target base station side from executing PDU session resource modify/modification indication and other processes again to perform the data transmission tunnel address coordination after the terminal completes the handover. Resource admission control efficiency of the target base station side can be improved, so that the PDU session enters a reasonable state of UPF split or UPF non-split as soon as possible, and signaling resources between the target base station side and a core network can be saved.
