Section: 6.50.2.3 Other aspects
Content: Subject to HPLMN policy and network control, the 5G system shall be able to collect charging information related to traffic steering and/or switching of a DualSteer device’s user data across two 3GPP access networks. NOTE 1: Charging information should be collected for both 3GPP access networks; in case the two 3GPP access networks belong to different PLMNs, or a PLMN and NPN, a proper business/roaming agreement among network operators is assumed. Subject to home network operator policy and network control, the 5G system shall be able to support traffic steering and/or switching of a DualSteer device’s user data between a NPN and a PLMN, for one or more a DualSteer devices with a NPN subscription accessing NPN services, to meet specific QoS requirements for each device, assuming non-simultaneous transmission over the two 3GPP access networks. NOTE 2: The above assumes a NPN hosted by a PLMN or offered as a slice of a PLMN, data anchoring in the NPN, and a business/roaming agreement between the PLMN and the NPN operator (if different).
