Abstract: Methods, apparatus circuitry, and storage media are described for mobile-terminated packet transmissions. In one embodiment, an apparatus of a control plane device configured to operate within an evolved packet network core identifies a first service flow event trigger associated with a first packet data unit (PDU) session and processes a path reselection for a first PDU session in response to the first service flow event trigger, wherein the path reselection determines a new gateway for the first PDU session resulting from the path reselection. Transmission of a change notification to an application server controller associated with the first PDU session is initiated in response to the path reselection. Transmission of a routing update to the new gateway in response to the path reselection is also initiated. In various embodiments, the trigger may be a mobility event, a load balancing event, or operations in association with an application server controller.
