AI Technical Summary

Problems solved by technology

The difficulty of correctly identifying this type of traffic means that protocol identification accuracy cannot be guaranteed
The higher the percentage of encrypted packets, the lower the detection rate
Furthermore, the continued increase in the number of connected applications and protocols in a typical UE device may increase the probability of false protocol detection, as new protocols and applications are added every year

Embodiment Construction

[0031] Specific details are set forth below, such as specific embodiments or examples, for purposes of explanation and not limitation. It will be understood by those skilled in the art that other examples may be used beyond these specific details. In some instances, detailed descriptions of well-known methods, nodes, interfaces, circuits and devices are omitted so as not to obscure the description with unnecessary detail. Those skilled in the art will appreciate that hardware circuits (e.g., analog and / or discrete logic gates, ASICs, PLAs, etc. processor or general purpose computer to implement the described functions in one or more nodes. Nodes that communicate using the air interface also have suitable radio communication circuitry. Moreover, where appropriate, the techniques may additionally be considered fully embodied within any form of computer-readable storage, such as solid-state memory, magnetic disk, or CD.

Abstract

Methods and apparatus for traffic monitoring in a network are provided. In one example aspect, a method of traffic monitoring in a first network node includes receiving a packet; determining that the packet matches a plurality of packet detection rules; and sending an indication to the second network node that the packet matches the plurality of packet detection rules.

Description

technical field [0001] Examples of the present disclosure relate to traffic monitoring in network nodes. Background technique [0002] In the 3GPP Standardization Forum, a reference architecture for 5G wireless communication networks is defined, eg in Section 4.2.3 of 3GPP TS 23.501 V0.5.0 (2017-05), which is incorporated herein by reference. figure 1 An example of a 5G network architecture 100 is shown. The 5G network architecture 100 includes the following entities and interfaces. [0003] Packet Flow Description Function (PFDF) 102: In the 5G architecture 100, this is included in the Network Exposure Function (NEF) 104, eg to reduce the number of network functions in 5G. The PFDF 102 processes the Packet Flow Descriptions (PFDs) associated with the application identifier(s) and transfers them to the Session Management Function (SMF) 106 via the NG GW interface. The SMF 106 communicates these PFDs to the User Plane Function (UPF) 108 through the N4 interface and PFD man...
