Title:
CONGESTION CONTROL FOR RADIO ACCESS NETWORKS (RAN)
Document Type and Number:
WIPO Patent Application WO/2014/052044
Kind Code:
A3
Abstract:
Systems and methods are disclosed for controlling congestion in a Radio Access Network (RAN). One embodiment comprises a charging system of a network. The charging system receives a traffic report for a RAN indicating a congestion condition in an area of the RAN. The charging system then identifies a subscriber in the area of the RAN, identifies a service plan for the subscriber, and generates modified rules that deviate from predefined rules in the service plan of the subscriber in response to the congestion condition. The charging system then provides the modified rules to a network entity, such as a Policy and Charging Rules Function (PCRF), that performs policy and charging control for a service requested by the subscriber.
