WIN Overview




An “Intelligent” Network separates the Service Layer from the
Switching and Access (Radio) Layers - the “Intelligence” resides in
the Service Layer
Major benefit to network operators: Services are created, tested,
modified, and deployed on computer platforms instead of on switches
- better because there are fewer of them, cheaper and easier to upgrade
Major benefit to customers: they can roam onto partner networks and
the service continues to function with no change
Local Exchange Carriers and Long Distance Carriers have operated
Intelligent Networks for years - they are the “brains” behind revenue
generators such as Calling Card, Calling Name Presentation, and
800/900 numbers

WIN Being Developed In Packages



The Engineering is complex - so the work has
been broken into large packages
Each package contains a set of serviceindependent “triggers” and “capabilities”
Each package supports a variety of services each network operator
can work with its
suppliers to develop the
services demanded
by the local market

WIN Capabilities

The first package [WIN Phase 1] supports basic
Call Origination and Call Termination services

Some equipment vendor (e.g. Ericsson) product plans
include switch upgrades to support the WIN triggers and a
WIN-capable “Service Control Point” (e.g. Jambala) that
conforms to this schedule
WIN-capable SCPs are also available from other
equipment suppliers (e.g. Compaq, Lucent, Nortel), any of
which will inter-operate successfully in the wireless
network

Wireless Intelligent Network [WIN]
Phase 1 - Basic Services


WIN Phase 1 defined the basic architecture - and the first
batch of triggers and capabilities - and the first batch of
services
Typical WIN Phase 1 services are:
 Calling Name Presentation
 Incoming Call Screening
 Voice Controlled Services
Network Strategy
Confidential and Proprietary
Calling Name Presentation
Calling Name Presentation is a simple
call screening capability that allows the
called party to see the name of the calling
party during alerting.
This WIN-based feature allows the
switch, upon detection of a termination
call attempt to the subscriber, to query a
database which will “look up” the name
of the calling party. This information is
transmitted to the serving network and
the Calling Name Information is
presented to the subscriber during
alerting.
Network Strategy
Confidential and Proprietary
Incoming Call Screening
Incoming Call Screening is a
sophisticated call screening
capability that allows the called
party to define the criteria for
which incoming calls are to be
delivered, and the termination
treatment given.
This WIN-based feature compares
the characteristics of all incoming
calls screening factors The feature
can also be enhanced by
employing an Intelligent Peripheral
which acts as the subscribers agent
in screening and routing all
incoming calls.
Screening Factors:
- Identity of Caller
- Time-of-Day, Day-of-Week
- Location of Called Party
- Status of Called Party

Voice Controlled Services
Voice Controlled Services allow the subscriber
to perform a number of tasks using spoken
voice commands instead of pushing buttons on
the mobile phone.

VCS employs a mulitilingual standardized
syntax and vocabulary to ensure seamless
service throughout the service area, but also
provides the service provider with the
flexibility to create innovative service scripts.

Phase 2 - Charging Services


WIN Phase 2 uses the same basic architecture - but adds a
second batch of triggers and capabilities - and the second
batch of services
Typical WIN Phase 2 services are:
 Pre-Paid Charging
 Freephone (800 Service)
 Premium Rate Charging
(900 Service)
 Advice Of Charging
Network Strategy

Pre-Paid Charging
Pre-Paid Charging is already a
hugely successful product for
Rogers Wireless
Examples of WIN Pre-Paid Applications
Fraud
Monitor
International
Roaming
Specialized
Greetings
WIN reduces the cost of
providing Pre-Paid by replacing
the current trunk-based point
solution with a computer-based
network solution.
Potentially WIN can also
enhance the existing service by
customizing it to fit specific
niche markets - special greetings,
fraud monitors, international
roaming, etc.

Freephone (800 Service)
“Freephone” is the generic term
for 800 services - calls where all of
the charges are paid for by the called
party.
General
Motors
Freephone is a huge revenue
generator for the wireline network
operators - more than a billion
dollars per year in Canada.
1-800-Flowers
Holiday Inn

Platform
(800 Application)
Wireless subscribers have even more
incentive to dial 800 - if their airtime
is free (e.g., paid for by General
Motors,
1-800-Flowers, or Holiday Inn).

Premium Rate Charging
Premium Rate Charging is a
service where the subscriber
pays a premium on top of their
regular airtime - for the
privilege of talking to a party
with specific knowledge or
skills.
1-800-Psychic
Premium Rate Charging is also
a substantial revenue generator
for the wireline networks.

Advice Of Charging
Advice of Charging is a simple concept:
advise the customer of charging
information in real time.
Advice of Charging can use the handset’s
text display, or an announcement, or a
combination of both.
The content of the message is up to the
service provider. Any type of
information, any language, any unit
(time, dollars, percentage, under/over,
etc.) can be sent to the subscriber’s
handset at any point during the call.

Phase 3 - Location Services



WIN Phase 3 adds a third batch of triggers and capabilities - and a
third batch of services, but requires a prerequisite - choice of Location
Determining Technology to determine location of the caller
This technology will soon be a government requirement to support 911
service - we might as well generate some revenue from this investment
by deployment of location services
Typical WIN Phase 3 location services are:
 Location-Based Charging
 Fleet and Asset Management
 Location-Based Information Service
 Enhanced Call Routing
Network Strategy
Confidential and Proprietary
Location-Based Charging
Location-Based Charging
allows the service provider to
divide the network service area
into zones.
The charge for services may
then be adjusted based on
which zone the subscriber is in.
Zone 1
Zone 2
Zone 3
Network Strategy

Fleet and Asset Management
Fleet and Asset Management
service allows a subscriber to
track the whereabouts of fleet
vehicles or other assets.
The service could also be used
for tracking people or pets.
Triggers can be armed so that
reports are generated when
fixed assets start to move - or
when moving assets stop
moving. Or the service logic
can simply poll the location on
a periodic basis.

Location-Based Information Service
Location-Based Information
Services provide the user with
information which is tailored
to their current geographic
location.
Similar to current service
offerings such as “OnStar”, a
vehicular appliance which
assists the driver by providing
information on local roads,
hotels, gas stations, restaurants,
and so on.

Enhanced Call Routing uses
the geographic location of the
subscriber to intelligently route
the call.

Implementation Strategy

Implementing WIN services requires several steps:
 Upgrade MSCs to support WIN triggers
Upgrade HLRs to support WIN triggers and service
profiles
 Deploy WIN service logic programs


The following specific issues must be carefully
addressed:
 Interaction with existing services
Increasing signaling traffic volume
 Interoperability while roaming with partners

Service Creation Options



“Turn-Key” solutions from one infrastructure
supplier (Ericsson), using applications built
specifically for one particular platform(Jambala)
“Off-The-Shelf” solutions from potential software
developers, using applications developed for an
open SCP platform
“Do It Yourself” solutions developed by each
individual operator using Service Creation
Environment to be provided by a variety of
infrastructure suppliers

Future Developments

In general, the future WIN development will
include:
 Additional triggers and operations for circuit-switched
call models
 “Mobility” model and associated triggers
 Call models and triggers for packet-switched services


Next standards project will be the development of
WIN capabilities to support Location Based
services, expected to complete by end of year 2000
The most likely area for further standards work will
be “porting” the WIN capabilities into a packetswitched environment

Conclusions



WIN Capabilities are the enabling technologies
for a wide range of revenue-generating, loyaltybuilding services
Everything is in place to add WIN capabilities to
the existing wireless network - the next step
would be to select a service for deployment and
install the appropriate WIN-capable equipment
Even a “small scale” deployment would be
beneficial as it would propel us up the “learning
curve” - we would be prepared in case our
competitors launch a WIN-based service
