摘要
Various embodiments relate to a method performed by a network node for terminating an S9 roaming session, the method including: receiving a Gx roaming session termination request; forwarding a corresponding S9 roaming session termination request to a controlling Policy and Charging Rule Function (PCRF) node; waiting a preconfigured time interval; and terminating the S9 roaming session without receiving an expected S9 acknowledgement message from the controlling PCRF node. Embodiments can include scheduling an IPCAN session audit for a selected IPCAN session of an S9 roaming session at preconfigured time intervals; generating an IPCAN session status request message; converting the IPCAN session status request message to a corresponding S9 status request message; forwarding the S9 status request message to a visited PCRF node; and responsive to receiving an S9 message indicating an unknown session from the visited PCRF node, removing the selected IPCAN session at the network node.
