Policy In The Context of 4G

EPC defined in 3GPP

TS23.401 and TS23.402 Replaces GPRS corenetwork with flatter all-IPnetwork

PCRF is effectively an

essential element, notstrictly part of EPC butrequired to give dynamiccontrol over bandwidth,charging and network

usage Packet Data Network

Gateway (P-GW) is a keynode for policyenforcement

Subscribers Rule

Question: Which of the following statements best represents your companys viewabout its planned use of policy management solutions?

68%

32%

Our long-term goal is to

apply most policies at

the level of individual

Many policies willcontinue to be applied at

a general level or to

applications that are

running on the network.

16/30

Smart Networks: A To Do List Apply yield management techniques to maximize efficient use of

resources

Gain an ever-deeper understanding of what customers are doing, inreal time where necessary

Allow customers to apply theirown filters to their broadband services(charge me only for this; prevent my children doing this, etc)

Warn customers about threats/problems, and offer solutions

Enable users (consumers) to control non-flat-rate expenditure in real

time (inform/warn; deploy real-time device meters; offer alternatives) Anticipate customer needs and offer services related to patterns of

use (analogous to targeted Web destination advertising and e-commerce recommendation engines)

Enable enterprises to direct services and applications at relevant

customers (those who are in a specific location, using a specificdevice, on a network with these characteristics etc)

Enable developers to refine and target services more effectively,based on detailed (anonymized) subscriber behaviour and usageprofiling.


17/30

Use Case: Service Optimization Based OnCustomer Value And Usage Patterns

Identify services that Platinum tier customer A values, taking

the guesswork out of this process When key parameters for these services e.g., gaming-- fall

below threshold, provide priority access to these services

Other possible actions: Shift the customer on to an alternative network infrastructure (e.g. to a

WiFi network) when available, to improve gaming service performance Alert operator when the customer stops using applications of knownvalue, and take appropriate action

Alert operator to significant changes in the customers application usepatterns that might be a trigger for an upgrade offer

Alert operator when an unknown/new device is utilized by the customer

Allow the service provider to offer related services from third partypartners, based on patterns of use among similar customers

Same capabilities could used to automate 0.facebook.comtype services


18/30

Technology Implications, 1

An up to date view of Internet applications protocol

signaturesan area of continual and accelerating change The latest heuristic and behavioral tools for packet flow

analysis to identify disguised or encrypted traffic

Detailed insight into content (e.g. not just identify P2P, butidentify specific types of P2P content in order to filter good

from bad content) User/service behavioral analysis to refine the performance

of services and service offers

Ability to extract more information from Web sessions (set-

up time, duration, device etc), sometimes calledmetadata, to improve customer experience, meet legaldata retention requirements, and so on


19/30

Technology Implications, 2

More broadband service customers, with ultimately all mobilecustomers becoming broadband customers

Greater proportion of customers to whom DPI-based policyenforcement must be appliedin the LTE era, in fact, this islikely to mean all customers

More customers accessing Internet services, generating aneed for more intelligent handling of traffic

More traffic per customer as a result of the transition to LTE

More applications and services per customer

More powerful devices with new capabilities such as multi-tasking, HD video handling, etc

More policy & DPI decisions/transactions per customer


20/30

Build Or Buy: Whats Right For TEMs?

Is the value of this capability rising for our customers? Do we need these capabilities for strategic reasons?

Is this adjacent to our existing skill-sets?

Do we have the core skills in-house to add this?

Is this domain evolving rapidly? Will the cost of insourcing exceed the cost of outsourcing?

Can we easily acquire and retain these capabilities fromreliable suppliers?

Can we easily integrate a third party product into oursolution?

Can we still differentiate ourselves if we buy this capabilityin from a third party?


21/30

Why Outsourcing Is Likely ToIncrease

Market and technology development cycles are bothspeeding up requiring continual upgrades and shorterrelease cycles in this area

There is a requirement for a wider set of capabilitiesthan hitherto to meet overall customer goals,demanding more specialized IT skills and straininginternal capabilities

Internal cost and resource constraints are increasingfor TEMs as competition intensifies

The existence of a flourishing supplier ecosystem andstandardized approaches to hardware design alloweasier integration of third party technologies


22/30

Summary

DPI will be a key technology underpinning thetransition to LTE and all-IP mobile networks

This transition will also increase the need for abetter understanding of traffic, applications andsubscribers

This expanded role will put great pressure onexisting DPI engines, making outsourcing tospecialists more attractive

Case Study Mobile Broadband

--

1. Mobile Broadband application shows a who, what,

where view of network usage

2. With integrated Customer Experience Management

capability the solution provides critical view ofnetwork resource usage by user and handset types

All steps needed to assess packet services are

available

for inspection in real-time and for customer care

3. Packet service performance can be broken down by

cell/service area in order to know how each network

element is contributing to packet service performance


28/30

Case Study More Details

-

-

1. Network user complains aboutpoor throughput during a particular

time period

2. Customer Experience

Management investigation (entry of

customer phone number) was

performed looking into particular

time period of the problem

Analysis showed that handset was

not using the proper serving cell.Performance affected by interference

Unexpected used cell that is

positioned on the top of a hill

Location of user. Can be tracked

real-time and historically

What applications are used?

Technical Details:

1. Monitoring of Gn and Iups

interfaces correlation across

interfaces

2. Throughput at Gn interface of

2.5 Gbit/sec

3. Access to historical XDRs back to

4 weeks (generally would

depend uniquely on storage

sizing)
