Abstract
The present disclosure describes methods and apparatus for supporting QoS and media flow mapping over simultaneous connection for a user equipment (UE), when the simultaneous connections are established over heterogeneous systems having different QoS models, such as 3GPP LTE (4G) QoS model and 3GPP 5G QoS model. The 4G and 5G networks may share the user plane and/or share a policy server. In one aspect, methods for consolidating and distributing the QoS for the NGBR flow and bearer across simultaneous PDN connection over 4G and PDU session over 5G to the same data network (DN) or different DNs are provided. In another aspect, methods are provided for mapping one or more media flows of a multimedia session, such as an IMS session, over simultaneous 4G and 5G connections for a UE are provided, where the 4G connection and the 5G connection for the UE may or may not share the assigned IP address for the UE.
