Title:
ADDRESS COORDINATION METHOD, DEVICE, BASE STATION, SMF NETWORK ELEMENT AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/174358
Kind Code:
A1
Abstract:
Provided by the present disclosure are an address coordination method, device, base station, SMF network element and storage medium. In the process of a terminal being handed over from a source base station side to a target base station side, a UPF shunt state of a PDU session on the terminal may be determined and corresponding coordination of data transmission tunnel addresses may be completed, thus enhancing the flexibility of PDU session shunt control during the process of terminal handover, avoiding coordination of data transmission tunnel addresses by executing PDU resource modify/modification indication and other processes again at the target base station side after the terminal has completed handover; The present invention not only may improve the resource reception control efficiency at the target base station side, making the PDU session enter a reasonable state for UPF shunt or UPF non-shunt as soon as possible, but may also save signaling resources between the target base station side and the core network.
