Method for PCRF to autonomously respond to cell capacity shortage
First Claim
1. A method performed by a Policy and Charging Rules Node (PCRN) for responding to a service request based at least in part on a status of a subscriber network, the method comprising:
- receiving at the PCRN at least one event message related to a transfer facilitated by the subscriber network;
storing data regarding the at least one event message in an Event Storage;
receiving at the PCRN a service request for resources controlled by the PCRN;
determining the status of the subscriber network;
determining from the status of the subscriber network whether the service request should be fulfilled as requested; and
if the service request should be fulfilled as requested, generating at least one new policy and charging control (PCC) rule to fulfill the service request,wherein the step of determining the status of the subscriber network further comprises;
identifying at least one statistical trend among a subset of the data in the Event Storage; and
determining from the at least one statistical trend whether an element of the subscriber network is congested.

Abstract
Various exemplary embodiments relate to a method and related network node and machine-readable storage medium including one or more of the following: determining network status; receiving an application request at the PCRN; generating a new PCC rule in response to the application request and network status; and providing the new PCC rule to a PCEN. Various exemplary embodiments further include receiving an event message, determining the network status from received event messages and isolating congestion using previously issued PCC rules and a network topology.

9. A policy and charging rules node (PCRN) for responding to a service request by generating at least one policy and charging control (PCC) rule based at least in part on a status of a subscriber network, the PCRN comprising:
-
an interface that receives a service request for network resources controlled by the PCRN; an Event Storage that stores data related to received event messages related to a transfer facilitated by the subscriber network; a Rule Storage that stores data related to PCC rules generated by the PCRN; a Network Status Analyzer that determines the status of the subscriber network by identifying at least one statistical trend among a subset of the data in the Event Storage and the data in the Rule Storage and determining from the at least one statistical trend whether an element of the subscriber network is congested, and determines whether the service request should be fulfilled; and a Rule Generator that, when the service request should be fulfilled, creates at least one PCC rule based on the received service request. - View Dependent Claims (10, 11, 12, 13, 14)

15. A non-transitory machine-readable storage medium encoded with instructions for a Policy and Charging Rules Node (PCRN) to respond to a service request based at least partially on a status of a subscriber network, the non-transitory machine-readable storage medium comprising:
-
instructions for receiving at the PCRN at least one event message related to a transfer facilitated by the subscriber network; instructions for storing data regarding the at least one event message in an Event Storage; instructions for receiving at the PCRN a service request for resources controlled by the PCRN; instructions for determining the status of the subscriber network; instructions for determining from the status of the subscriber network whether the service request should be fulfilled as requested; and instructions for generating at least one new policy and charging control (PCC) rule to fulfill the service request if the service request should be fulfilled as requested, wherein the instructions for determining the status of the subscriber network further comprise; instructions for identifying at least one statistical trend among a subset of the data in the Event Storage; and instructions for determining from the at least one statistical trend whether an element of the subscriber network is congested. - View Dependent Claims (16, 17, 18, 19, 20)
