User plane function (upf) control with coexistence of policy control and packet filters dynamically generated at the session management function (smf)

Abstract

Systems, methods, apparatuses, and computer program products for UPF control with coexistence of policy control and packet filters dynamically generated at the SMF. For example, if the SMF obtains an event subscription with traffic descriptors from another entity, and if there is no installed PDR with the same traffic descriptor, the SMF may construct a PDR with an action according to the subscribed event. The SMF may configure the UPF with the constructed PDR. In certain embodiments, to construct the PDR, the SMF may copy the PDR that would have previously matched the incoming traffic described by the traffic descriptor in the notification subscription, and associates the PDR with a higher priority, the traffic descriptor and a notification action according to the subscribed event. To configure the UPF, the SMF may provide the PDR with the higher priority, the received traffic descriptor, and the notification action, according to some embodiments.
