Section: 6.44.2.3 Subscription-based routing to a particular core network (e.g. in a different country)
Content: The 5G system shall be able to support a mechanism such that all traffic pertaining to UEs of specific subscribers which is sent to the HPLMN is forwarded to a target PLMN, e.g., to enable further handling of those UEs by the target PLMN. The forwarding mechanism shall minimize traffic in the HPLMN, e.g., by using efficient means to forward traffic from selected UEs. NOTE 1: The above requirement assumes that the HPLMN has an agreement with the target PLMN, and routing policies are in place. NOTE 2: In case of UEs connected via a VPLMN, it is assumed that traffic is forwarded to the target PLMN by the HPLMN.
