EXTENDING REVALIDATION-TIME OF DIAMETER SESSIONS
First Claim
1. A method performed by a Policy Charging and Control Node (PCRN) for updating a session associated with a subscriber in response to an event, the method comprising:
- receiving at the PCRN an event message indicating that an event has occurred within the session;
retrieving subscriber information including at least one incremental value associated with the event for the subscriber;
determining an updated value based on the at least one retrieved incremental value and at least one reference value; and
responding to the event message with an update message including the updated value.

Abstract
Various exemplary embodiments relate to a method performed by a Policy Charging and Control Node (PCRN) for updating a session associated with a subscriber in response to an event. The method may include receiving at the PCRN an event message indicating that an event has occurred within the session; retrieving subscriber information including at least one incremental value associated with the event for the subscriber; determining an updated value based on the at least one retrieved incremental value and at least one reference value; and responding to the event message with an update message including the updated value. Various exemplary embodiments may further include configuring a subscriber profile repository to include at least one incremental value and terminating the session if the subscriber is not allowed to use incremental updates or no incremental value is defined for the subscriber.

5. The method of claim I wherein the event message indicates that a revalidation timeout has occurred, the incremental value is a subscription extension time, and the reference value is a current time,
wherein the step of determining an updated value comprises adding the subscription extension time to the current time.

8. A Policy and Rules Charging Node (PCRN) for updating a session in response to an event message, the PCRN comprising:
-
a first interface that receives an event message indicating that an event has occurred in a session of a subscriber; a second interface that communicates with a subscriber profile repository and receives at least one incremental value associated with the event for the subscriber; a rule engine that selects a decision rule based on the event and applies the decision rule to determine an update value based on the at least one incremental value and at least one reference value; and a session manager that transmits the update value via the first interface. - View Dependent Claims (9, 10, 11, 12)

13. A machine-readable storage medium encoded with instructions for a policy and rules charging node (PCRN) to update a session associated with a subscriber in response to an event, the machine-readable storage medium comprising:
-
instructions for receiving at the PCRN an event message indicating that an event has occurred within the session; instructions for retrieving subscriber information including at least one incremental value associated with the event for the subscriber; instructions for determining an updated value based on the at least one retrieved incremental value and at least one reference value; and instructions for responding to the event message with an update message including the updated value. - View Dependent Claims (14, 16, 17, 18, 19)
