When performing load balancing in a wireless extended self-organizing network (extended SON), network health status is monitored by collecting network measurement data and identifying network nodes that require policy adjustment. Based on the network measurement data, network and/or user policies are automatically adjusted and policy updates are disseminated by a policy and charging rule function module to a packet gateway (PGW) as well as to one or more non-PGW network nodes (e.g., base stations, mobility management entity (MME) nodes, radio network controller (RNC) nodes, and the like). The automated policy updates are locally enforced at the nodes that receive the updates, rather than solely at the PGW node. |
