6.2.5.2 QoS in MA PDU session
Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).
In an MA PDU session, unless it:
- is established over non-3GPP access; and
- has a PDN connection as a user-plane resource;
the UE shall have one set of QoS rules, one set of QoS flow descriptions and one session-AMBR. The network can provide the set of QoS rules, the set of QoS flow descriptions and the session-AMBR of the MA PDU session via either access of the MA PDU session. In an MA PDU session, the UE shall support:-
- modification or deletion via an access of a QoS rule or a QoS flow description; and
- modification via an access of the session-AMBR;
of the MA PDU session created via the same or the other access.
In an MA PDU session:
- established over non-3GPP access; and
- with a PDN connection as a user-plane resource;
the UE shall have two sets of QoS rules, two sets of QoS flow descriptions and two session-AMBR values - one is maintained via non-3GPP access and the other is associated with EPS bearer contexts of the PDN connection and maintained via Extended protocol configuration options IE parameters received via the PDN connection.
