Message And System For Application Function Influence On Traffic Routing
An aspect of the disclosure provides for a method for user equipment (UE) internet protocol (IP) address management. The method includes sending by an application function (AF), a request to a policy control function (PCF), the request including information identifying traffic and an indication that a UE IP address associated with the traffic should be preserved. The method further includes sending by the PCF, to a session management function (SMF) being responsible for managing a Protocol Data Unit (PDU) session associated with the traffic, a policy and charging control (PCC) rule including the indication. In some embodiments, the request is sent by the AF to the PCF via a network exposure function (NEF). In some embodiments, the method further includes managing, by the SMF, the UE IP address according to the PCC rule. In some embodiments, the managing includes preserving the UE IP address for a PDU session associated with the traffic. In some embodiments, the preserving includes preventing reselection of a protocol data unit (PDU) session anchor (PSA) to which the UE IP address is associated.

- 18. A method for coordination between an application function (AF) and a network including a session management function (SMF), comprising:
sending, by a policy control function (PCF), a policy and charging control (PCC) rule, the PCC rule indicating an AF subscription to a notification of a user plane (UP) path management event and including an indication that indicates the AF will provide an AF response to the notification of the UP path management event; receiving, by the SMF, the PCC rule; according to the PCC rule, sending, by the SMF, the notification of the UP path management event to the AF, wherein the notification indicates a data network access identifier (DNAI) change; and maintaining, by the SMF, an existing UP path while waiting for the AF response to the UP path management event notification from the AF.
- 30. A communication system comprising a policy control function (PCF) and a session management function (SMF), wherein
the PCF is configured to send a policy and charging control (PCC) rule, the PCC rule indicating an AF subscription to a notification of a user plane (UP) path management event and including an indication that indicates the AF will provide an AF response to the notification of the UP path management event; the SMF is configured to: receive the PCC rule; according to the PCC rule, send the notification of the UP path management event to the AF, wherein the notification indicates a data network access identifier (DNAI) change; and maintain an existing UP path while waiting for the AF response to the UP path management event notification from the AF.
