DESCRIPTION
Growing consumer demand for smart phones, coupled with the continuing performance growth of such devices, means mobile users are increasingly using applications that make bandwidth and connection demands of the carrier network. There is already a lot of data traffic on mobile networks and at peak periods that might mean congestion and slower access to data. Network Operators, in order to deal with such demand, deploy network-based PCRF and PCEF/TDF solutions that respond to the network traffic at that particular time and offer a level of control according to various access policies.TRANSCRIPT

What’s the Problem?
• Bandwidth hungry and connec1on intensive applica1ons – Generate significant upstream traffic levels
• Increases strain on RAN • Implica1ons?
– CAPEX increase through capacity investment – OPEX due to increased management overhead
• Result? – More money – Decreased customer sa1sfac1on

Why does it Occur?
• ChaGy apps connect “at will” to radio access func1on, driving traffic
• Users have many applica1ons open, but only a few are ac1ve – Background apps consume resources
• Network-‐based PCRF / TDF func1ons can only respond when traffic leaves RAN
• RAN traffic is beyond detec1on capabili1es of current solu1ons
• It’s not just physics….. 3

What can be Done?
• Extend PCEF func1onality to mobile devices • Deploy lightweight mobile client to manage local radio connec1ons
• Allow “foreground” applica1ons to connect freely to network
• Background applica1ons are controlled via configurable 1me period – Can connect, but frequency reduced

What’s the Result?
• Ini1al deployment: – Tier 1 operator – PRCF partner
• 6 million clients so far • To be extended to en1re Android user base
– OTA / Embedded
• $40 million CAPEX saving over 3 year period – Reduce RAN and network control plane investments

What Happens Next? • Extend centralised Policy Enforcement and Traffic
Management to client device (fixed & mobile) • Real-time visibility and control of actual service performance
and user experience – Customer view of the network (not network view of the customer)
• Real-time reaction to local and network factors – Location, traffic type, cell congestion, customer package, WAN-link
type • Multiple Use Cases including
– Managing “Chatty Apps”, Illegal tethering, Advanced data offload, Signalling reduction, Cell congestion management, Roaming handset data
• Establishes secure architecture for future Use Cases • Scalable and secure software solution
