Abstract

A method of processing a Domain Name Server, DNS, query received from a User Equipment, UE, in a telecommunication network, wherein said method comprises the steps of receiving (102), by a User Plane Function, UPF, an encrypted message from said UE, determining (103), by said UPF, that said encrypted message is an encrypted DNS query by establishing that a destination address in said encrypted message corresponds to an address of a DNS server comprised by said telecommunication network, and forwarding (104), by said UPF, said encrypted DNS query to said DNS server.

Dependent claims

A method of supporting encrypted Domain Name Server (DNS) query functionality for a User Equipment (UE) in a telecommunication network, wherein said method comprises the steps of:

receiving, by a Session Management Function (SMF) from a Policy Control Function (PCF), a policy create message comprising an indication that said UE is subject to said encrypted DNS query functionality;
and
sending, by said SMF to a User Plane Function (UPF), a session establishment/modification request, wherein said request comprises a usage report rule for request said UPF to notify said SMF of received encrypted DNS queries origination from said UE.

A Session Management Function (SMF) comprised by a telecommunication network arranged for supporting encrypted Domain Name Server (DNS) query functionality for a User Equipment (UE) in the telecommunication network, wherein said SMF comprises:

receive equipment arranged for receiving, from a Policy Control Function (PCF), a policy create message comprising an indication that said UE is subject to said encrypted DNS query functionality;
and
transmit equipment arranged for sending, to a User Plane Function (UPF), a session establishment/modification request, wherein said request comprises a usage report rule for request said UPF to notify said SMF of received encrypted DNS queries origination from said UE.

Dependencies are inferred from the claim text.
