Extending revalidation-time of diameter sessions
First Claim
1. A method performed by a Policy and Charging Rules 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 from an enforcement node 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, the incremental value defining an amount of an incremental change for the subscriber in response to the event;
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 by sending an update message including the updated value to the enforcement node.

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.

8. A Policy and Charging Rules Node (PCRN) for updating a session in response to an event message, the PCRN comprising:
-
a first interface that receives an event message from an enforcement node 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, the incremental value defining an amount of an incremental change for the subscriber in response to the event; 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 to the enforcement node via the first interface. - View Dependent Claims (9, 10, 11, 12)

13. A tangible non-transitory machine-readable storage medium encoded with instructions executable by a processor of a Policy and Charging Rules 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 from an enforcement node 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, the incremental value defining an amount of an incremental change for the subscriber in response to the event; 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 by sending to the enforcement node an update message including the updated value. - View Dependent Claims (14, 16, 17, 18, 19)
