Case Study
A Policy-based Management Solution for
Wireless Access Networks
Introduction
Enterprise Networks
Mobile and fixed operators are looking for ways to manage their
backhaul and access network infrastructure in a way that optimizes
network utilization, reduces cost and maintains subscriber
experience. Often, significant parts of this infrastructure are
wireless, which makes the overall performance prone to changing
environmental conditions and subscriber behavior.
In a typical enterprise access scenario, involving INTRACOM
TELECOM’s WiBAS™ carrier-grade PtMP product, a bouquet of
services is available to demanding subscribers. The total available
bandwidth is in turn partitioned to each enterprise served, up to
the individual end-users within the same building.
Off-the-shelf network & service management tools usually have
access up to Layer 2 only (data link), and therefore operators can
only enforce undifferentiated ‘gross’ policies, applied horizontally
across all subscribers, no matter what their importance and
individual needs are. For example, a common such action might be
to cut-off most or even all IP data traffic and allow only voice when
the wireless infrastructure capacity is reduced via Adaptive
Modulation in order to cope with external/environmental
conditions.
INTRACOM TELECOM proposes an offering with fine-grained Layer 7
policies at network and enterprise level, or even individual user
level as necessary. Such a solution is implemented by a unified
Service & Network Management system that includes Policy
Charging and Rules Function (PCRF) that detects and manages
congestion in real-time.

Congestion may occur at the following three points:
1. Terminal Station – due to heavy internet usage from subscribers
of a single enterprise (e.g. peer-to-peer file sharing, video
streaming)
2. Wireless connection – due to external/environmental
conditions (e.g. adaptive modulation mechanism lowering
the physical mode of the respective link)
3. Base Station sector – due to oversubscription at the same
sector
The challenge is to intelligently detect and manage congestion
in real-time.
The Solution
INTRACOM TELECOM’s Unified Service & Network Management
Suite (uni|MS™) incorporates ActionRuler™, a state-of-the-art
Policy Charging and Rules Function (PCRF) add-on application that:
• Detects in real-time congestions, via threshold crossing alerts
(TCA) sent from managed elements.

The Challenge
• Automatically begins real-time detailed performance data
collection from all elements involved in congestion, which are
in turn supplied to the Service Management Layer for Policy rules
function.
• Analyzes resource performance data and communicates with DPI
to determine in real-time what applications the subscribers are
using in the congested resources.
• Automatically makes intelligent policy decisions for each
subscriber active on the network and applies necessary finegrained policies at network or enterprise level, or even individual
user level as necessary to eliminate congestion.
Case Study
Benefits for the Operator
• uni|MS™ with the ActionRuler™ PCRF add-on application
provides awareness about enterprise and even subscriber
profile & needs (e.g. gold/ silver, prepaid/postpaid, etc.). The
operator can define policies that allow automatic intelligent
decision making to manage congestion for a network offering
multiple services, quality of service (QoS) levels, and charging
rules.
• Operators can offer as a service to their enterprise/corporate
customers the capability to define policies via a customer care
portal, increasing loyalty and revenues. The operators may apply
various charging schemes, such as:
 Charge per active rule
 Recurring fees (e.g. monthly fee)
 Once-off activation fee.
Benefits for the Enterprise
• Enterprises can now apply fine-grained Layer 7 policies tailored
to their own needs, by re-allocating precious bandwidth towards
high-priority IP applications.
• Enterprise Policies can be applied at various levels:
 Global Policies can be applied throughout the whole
enterprise
 Port-based Policies can be applied to users connected to the
network via a specific port
 Individual Policies can be customized to specific end-users.
The INTRACOM TELECOM Proposal
INTRACOM TELECOM offers a state-of-the-art Policy-based
Management solution, applicable to both Fixed and Mobile
Telecom contexts, which incorporates:
• uni|MS™, a carrier-class, multi-technology Unified Management
