Dynamic service and policy control based on radio condition notifications

摘要

A system for receiving, by a policy and charging rules function (PCRF) device and from a packet data network gateway (PGW) device, a signaling message for a subscriber data session, the signaling message including first radio condition notification (RCN) data identifying an amount/level of data service throughput available at a location with respect to a radio access network (RAN); generating, responsive to the signaling message, a request for the subscriber's quality of service (QoS) and policy information; sending the request for QoS and policy information to a home subscriber server (HSS) device; receiving, from the HSS device, the subscriber's QoS and policies; determining, based on the QoS and policies and the amount/level of data service throughput, QoS and policy decisions applicable to the subscriber at the location; and sending the QoS and policy decisions to the PGW device for implementation via the RAN.
