Abstract

Exemplary embodiments include methods for establishing a user-requested protocol data unit (PDU) session in a user's visited public land mobile network (VPLMN), by a session management function (V-SMF) in the VPLMN. Such methods include receiving, from an access and mobility management function (AMF) in the VPLMN, a PDUSession_CreateSMContext Request to establish the PDU session to be routed through the user's home PLMN (HPLMN). The PDUSession_CreateSMContext Request identifies an SMF (H-SMF) in the user's HPLMN. Such methods include sending, to the identified H-SMF, a PDUSession_Create Request to create the PDU session. The PDUSession_Create Request includes an identifier of a session management (SM) context, in the V-SMF, that is associated with the PDU session. Such methods include receiving, from the H-SMF, a PDUSession_Update Request that includes an identifier of an SM context, in the H-SMF, that is associated with the PDU session. Embodiments also include complementary methods performed by the H-SMF.
