Abstract: Embodiments of the disclosure disclose a policy transmission method and apparatus in an NFV system. The method may include: obtaining, by a PMF unit, policy information, where the policy information includes a policy rule and a first policy parameter, and the first policy parameter is used to determine a target management unit for the policy rule in a MANO architecture of the NFV system; and transmitting, by the PMF unit, the policy rule to the target management unit based on the first policy parameter. According to the embodiments of the disclosure, an NFVO can be prevented from becoming a policy rule processing bottleneck.

Abstract: Embodiments of this application provide a packet transmission method, a communication apparatus, and a communication system. A target transport layer proxy network element establishes a fourth transport layer connection based on a first context of a source transport layer proxy network element, where the first context is a context about packet transmission of the source transport layer proxy network element on a first path. If the target transport layer proxy network element receives first indication information, and the first indication information indicates that application context migration between a first application server and a second application server is completed, the target transport layer proxy network element performs transport layer processing on a packet on a second path based on a second context of the target transport layer proxy network element, and transmits, on the second path, a packet obtained through the transport layer processing. Hence, a packet loss can be avoided.

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.
