Success Story: Unified Network Policy Control in 15+ LTE Networks
Our network policy control solutions have already been deployed by more than 15
LTE network operators worldwide to fulfill business intelligence, revenue generation
and cost reduction use cases.
Communications service providers (CSPs) are using Sandvine’s platform to address a broad range of use cases, which
can be grouped into three solution areas:

Business Intelligence:
by understanding how subscribers are using the increased speed and capacity of LTE
networks, operators can make informed decisions about future investments and new subscriber services

Revenue Generation:
after spending heavily to launch LTE networks, CSPs are looking to recoup their investments
through advanced subscriber services that cater to an audience hungry for personalization

Cost Reduction:
facing budget constraints for capital and ongoing operations, CSPs want to ensure network
efficiency, graceful congestion management and extended equipment lifetimes
Why are LTE network operators choosing Sandvine

for network policy control?
LTE operators who choose Sandvine for their network policy control solutions frequently cite our:

Sandvine Policy Engine:
the world’s most versatile
and powerful network policy control platform, unified
across the control and data planes

Broad Range of Use Cases:
address many use cases
with our single platform, including network analytics
and quality-aware congestion management

Tunnel Support:
inspect and apply network policy
control on tunnel content and tunnel headers

Standards Compliance:
support for legacy needs,
today’s requirements (including IPv6 and 3GPP
Diameter PCC) and emerging standards for tomorrow

Performance Density that Scales:
our platform
provides efficient control plane and data plane
scalability to support the world’s largest networks

Sandvine, LTE, and the Evolution of Network Policy Control.
“Sandvine is excited to be supporting the evolution of our customers’ networks to LTE.
The breadth of our policy control portfolio supports the operational efficiencies of all-IP
LTE deployments. With our integrated system we can leverage application, subscriber,
topology and congestion awareness to enable a wide range of usage-based services for
the mutual benefit of operators and subscribers.”
- Don Bowman, CTO, Sandvine
“Sandvine’s unified platform was an
important factor in our selection
process. Having policy decision making
distributed at multiple points of
presence – an ability unique to Sandvine
– gives us the flexibility and reliability
to deploy a variety of over-the-top
services our subscribers care about,
including parental controls and video

Deploying Sandvine in LTE
Due to the versatility of our data plane component, the Policy Traffic Switch (PTS), there are many deployment
options available to LTE network operators.
PTS Intersection
Deployment Considerations

Views all subscriber traffic

Enables Mobile Packet Core Offload use case

Traffic may be IPSEC-encrypted

Views all subscriber traffic in the GTP-U, including GTP-C for signaling

(e.g., subscriber-to-IP mapping, TEID, location) and all roaming traffic

S11 needs to be tapped to get mobile subscriber eNodeB change notifications

Views all subscriber traffic routed to the 3G network from the LTE network

Views additional location granularity (e.g., eNodeB, sector, updates)

No subscriber traffic on this interface

Views all traffic routed in “North” of the gateway

No GTP-C for subscriber mapping

No S8 roaming traffic

Cannot view traffic that is local to the P-GW
Example Deployment Diagram: PTS on the S5/S8 Interface
This diagram shows a network in which the PTS is deployed on the S5/S8 interface. In this scenario:

The PTS is inline, measuring subscriber traffic and enforcing policy actions as a PCEF

The Service Delivery Engine (SDE) is in the control plane, as both a PCRF and an external signaling gateway

The Subcriber Policy Broker (SPB) is the Subscriber Profile Repository (SPR) for the PTS and SDE, storing all
subscriber information and providing long-term business intelligence data
