Abstract
A policy control function (PCF) receives a first message from an application function (AF). The first message comprises: an always-on PDU session requested indication; an identity of a wireless device; and application service information. The PCF maps, based on the first message, the application service information to an always-on PDU Session for the wireless device. The PCF sends to a session management function (SMF), at least one policy and charging rule for the always-on PDU Session.
