Abstract: A home session management function (SMF) of a home public land mobile network (PLMN) receives, from a visited SMF of a visited PLMN from a visited SMF of a visited PLMN, a request for creation of a packet data unit (PDU) session of a wireless device. The request comprises first charging policy information determined based on a first policy of the visited PLMN. The home SMF sends, to the visited SMF and based on the request, a second charging policy information comprising: a charging method for the PDU session; and a charging parameter indicating a charging level for the PDU session.

Abstract: A session management function (SMF) sends, to an access and mobility management function (AMF), one or more first messages indicating user plane connection activations for a plurality of packet data unit (PDU) sessions to deliver downlink user data to one or more wireless devices. The SMF receives, from the AMF, a first time duration based on the user plane connection activations for the plurality of PDU sessions. The first time duration indicates a delay between receiving a downlink data packet and notifying the AMF about user plane connection activation for the downlink data packet. The SMF sends, to a user plane function, a second message to delay sending of further user plane connection activations to the SMF. The second message indicates a value of the first time duration.
