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.

Abstract: A communication method and apparatus are provided for transmitting packets of a data stream between user equipment. After receiving a first packet from a first user equipment, a user plane function (UPF) forwards the first packet to a second user equipment at a first moment, so that the first packet that arrives at the UPF before the first moment is not forwarded to the second user equipment until the first moment, to support deterministic sending and ensure that a time sensitive communication (TSC) packet is sent at a determined moment, so as to provide deterministic delay assurance for applications such as industrial control and telemedicine.

Abstract: This application provides a method for configuring assistance information and a communications apparatus. A first network device sends a path switch request message to an access and mobility management function (AMF), where the path switch request message is used to request for switching least one radio bearer (RB) of a terminal device from a second network device to the first network device. The first network device receives a path switch request response message from the AMF. The first network device determines, based on the path switch request response message, first burst arrival time at which a downlink quality of service QoS flow arrives at an ingress of the first network device within a first periodicity, where the first burst arrival time is used for downlink scheduling.

Abstract: A session processing method related to the field of wireless communications technologies is provided. The method discloses: obtaining, by user equipment (UE), session type information, where the session type information is used to indicate a type of a first session; and when a first application triggers a first service, determining, by the UE based on the session type information, whether a create session request needs to be initiated for the first service. According to the solutions provided in embodiments, before the create session request is initiated, the UE may determine whether to reuse a created session or create a new session. In this way, for a service that can reuse a created session, no new session needs to be created, thereby reducing signaling exchange between the UE and a network side.
