Section: 6.2.5.2 QoS in MA PDU session
Content: In an MA PDU session, unless it : a) is established over non-3GPP access; and b) 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: a) established over non-3GPP access; and b) 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.
