Abstract

The invention relates to a data transmission method, device and system and a user plane function device, and relates to the technical field of communication. The method comprises the following steps:determining a corresponding candidate PDR according to a received optimal priority; judging whether the candidate PDR matches the current data packet or not; under the condition of matching, determining a corresponding QoS flow as a matched QoS flow according to the candidate PDR to be used for transmitting the current data packet; and under the condition of mismatching, continuously selecting other priorities from the received priority list as new preferred priorities until the matched QoS flow is determined. According to the technical scheme, the system efficiency can be improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a data transmission method, a data transmission device, a data transmission system, a user plane functional device, and a computer-readable storage medium. Background technique [0002] For business scenarios where business data QoS (Quality of Service) requirements change frequently (for example, for applications such as game cloud rendering or video services), the application server can change), switching between several typical business solutions. [0003] In related technologies, under the QoS framework of the 5G core network, the SMF (Session Management Function, session management function) entity updates the relevant PDR (Packet Detection Rules, packet detection rules) in the UPF (User plane Function, user plane function) entity through the N4 message rules) information. Contents of the invention [0004] The inventors of the present disclosure ha...
