Title:
METHOD AND APPARATUS FOR DATA TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2022/142792
Kind Code:
A1
Abstract:
A method and apparatus for data transmission, the method comprising: a CU-CP determining first information, and sending, to a CU-UPF (a network element integrating a UPF and the CU-UP) by means of an SMF, identifier information of a DRB, identifier information of a PDU session corresponding to the identifier information of the DRB, and identifier information of a QoS flow corresponding to the identifier information of the DRB to allow the CU-UPF to establish a tunnel between the DRB and a DU according to the above information; according to the identifier information of the DRB and the identifier information of the QoS flow corresponding to the identifier information of the DRB, adding to a downlink packet the identifier information of the corresponding QoS flow and attribute information of the corresponding QoS flow; and sending the downlink packet by means of the tunnel, such that the transmission of the downlink packet and the attribute information of the corresponding QoS flow is achieved.
