Embodiment Construction

[0094] figure 1 Schematically showing a part of a reference architecture 1 of a fifth generation 5G service based architecture SBA to be deployed in a core network of a telecommunication system according to the prior art. 5G system architecture 1 generally distinguishes the following logical network functions NF:

[0095] -Authentication Server Capabilities AUSF 6

[0096] - Access and Mobility Management Function AMF 7

[0097] -Network Opening Function NEF 10

[0098] - NF repository function nrf 11

[0099] - Policy Control Function PCF 12

[0100]- Session management function SMF 8

[0101] - Network slice selection function NSSF 9

[0102] - Unified Data Management UDM 13

[0103] - Application function AF 14.

[0104] The logical NFs 6-14 of the core network are constructed from one or more services and together form the SBA domain. Within the SBA domain, service messages are transmitted and exchanged over corresponding communication interfaces, which are indica...

Abstract

A method of detecting Quick User Datagram Protocol Internet Connections, QUIC, traffic in a telecommunication network between a User Equipment, UE, and a Content Provider, CP, wherein said UE has an established application session with said CP, for a particular application, using QUIC as transport protocol, wherein said method comprises the steps of receiving, by a User Plane Function, UPF, comprised by said telecommunication network, from said CP, a list of connection identifiers that identify said established application session between said UE and said CP, receiving, by said UPF, a QUIC packet comprising a connection identifier, detecting, by said UPF, said QUIC traffic by determining that said connection identifier of said received QUIC packet is comprised by said list of connection identifiers.

Description

technical field [0001] The present invention relates to Quick User Datagram Protocol Internet Connection QUIC services in telecommunication networks, and more particularly to a method for enabling service differentiation in telecommunication networks in case of applications using QUIC as transport. Background technique [0002] The 3GPP standards have defined the system architecture for next-generation mobile networks, which will be the next major phase of mobile telecommunications standards beyond the current 4G. This architecture has been specified in 3GPP TS 23.501. [0003] Having a service-based interface in the control plane means that network function NF interactions are done by means of services: NFs in 5G content providers provide services that are consumed by other NFs in 5G. The roles of these entities and the above interfaces have been defined in 3GPP T23.501. [0004] The present disclosure relates to Quick User Datagram Protocol Internet Connection QUIC traff...
