[Analysys Mason]: "PCRF is becoming a core network element for CSPs"

A new report by Glen Ragoonanan (pictured), Senior Analyst, and Anil Rao, Analyst, Analysys Mason, covers the top-six network equipment manufacturers (NEMs): Alcatel-Lucent, Ericsson, Huawei, Nokia Siemens Networks, Cisco Systems and ZTE,

Among the findings, some relate to traffic management:  "Traffic management limited network infrastructure spend:

• CSPs continued to implement policy management (PCRF/PCEF) solutions for fair usage and RAN congestion, limiting network overload from video and P2P traffic, primarily.
   
• Data caps and Wi-Fi offloading reduced RAN congestion and limited spending on mobile backhaul capacity.
   
• Diameter signalling traffic is increasing rapidly, but is mostly contained in the CSP’s high-capacity core network.
   
• PCRF is becoming a core network element for CSPs. 

In additions, "Traffic management reduced investment in Business data services".
