Policy and charging rules node expired message handling

摘要

Various exemplary embodiments relate to a method and related network node and machine-readable storage medium including a policy and charging rules node (PCRN) receiving a plurality of related service requests from different devices. The PCRN may proceed to generate a policy and charging control (PCC) rule based on at least one service request and other information stored in the PCRN if a mate service request does not arrive during the duration of a waiting timer. If the mate service request arrives subsequent to the expiry of the waiting timer, the PCRN may then generate a subsequent PCC rule to replace the previously generated rule, with the new PCC rule incorporating information from both of the mate service requests.

1. A method performed by a policy and charging rules node (PCRN) for handling a request message, the method comprising:
receiving, through an Rx interface, a request message including a request from a user equipment (UE) requesting a new service data flow; generating a first policy control and charging (PCC) rule based on first information carried by the request message and second information carried by a mate message, received at the PCRN through a Gx interface, associated with the request message, wherein the first information and second information both describe information used to establish the new service data flow; and communicating with a gateway (GW) to cause: removal of a second PCC rule from the GW, wherein the second PCC rule was generated based on the second information prior to receiving the request message, and installation of the first PCC rule at the GW.
