Various exemplary embodiments relate to a method performed by a Policy and Charging Rules Node (PCRN) for managing communications sessions. The method may include: determining that a session is suspect of being inactive; sending an innocuous message to a network component that initiated the session; waiting for a response from the network component; if the PCRN receives a response from the network component, determining whether the session is inactive based on the response; and taking at least one management action for the session if the session is inactive. Various exemplary embodiments relate to a PCRN for managing communications sessions. The PCRN may include: one or more interfaces that communicate with network components, one or more PCRN blades that manage communications sessions, and a diameter proxy agent that determines which blade manages a session. Each PCRN blade may include a session manager, a timer and a session data storage. |
