Abstract

A communication method includes: determining a first central unit (CU)-user plane (UP) and a user plane function (UPF) network element that correspond to a quality of service (QoS) flow, where an access network device to which the first CU-UP belongs supports at least two CU-UPs; determining a first packet delay budget (PDB) for transmitting the QoS flow between the first CU-UP and the UPF network element; and sending the first PDB to the access network device, where the first PDB is used by the access network device to schedule an air interface resource. After the CU-UP corresponding to the QoS flow is determined, the PDB of the CU-UP corresponding to the QoS flow may be sent to the radio access network (RAN) device.

Claims11

Dependent claims

A communication method, comprising:

determining, by a communication apparatus, a first central unit user plane (CU-UP) and a user plane function (UPF) network element that correspond to a quality of service (QoS) flow, wherein an access network device to which the first CU-UP belongs supports at least two CU-UPs;
determining, by the communication apparatus, a first packet delay budget (PDB) for transmitting the QoS flow between the first CU-UP and the UPF network element;
and
sending, by the communication apparatus, the first PDB to the access network device, wherein the first PDB is to be used by the access network device to schedule an air interface resource;
wherein sending the first PDB to the access network device comprises:
initiating a session modification procedure;
and
sending the first PDB to the access network device in the session modification procedure;
wherein before initiating the session modification procedure, the method further comprises determining that the access network device supports the at least two CU-UPs, wherein determining that the access network device supports the at least two CU-UPs comprises:
determining that a plurality of PDBs are configured for a same 5G QoS identifier (5QI) between the access network device and the UPF network element.
