IP Enhanced Services In The New Era BY
KENNETH M. OSOWSKI
Anyone reading these pages already knows the convergence of legacy circuit-switched
networks (the PSTN) with emerging packet-switched data networks is changing the landscape
of telecommunications services. The million-dollar question is: How will this evolution
play out? And how can service providers take advantage of converged communications to
create new market opportunities, generate new revenues, and stay ahead of the competition?
The answer to the first question is elusive. The explosive growth of the Internet,
e-mail communications, and Web applications is driving the ascendance of Internet Protocol
(IP) as the protocol of choice for packetized communications, including voice. But, with a
vast infrastructure worth billions of dollars, the circuit-switched PSTN isnt going
away tomorrow. Add to this the dramatic worldwide growth of digital wireless PCS networks
and the entrance of cable providers into the voice and data communications world, and the
picture becomes fuzzy.
Given this fast-changing, multi-network environment, service providers must remain
flexible. Maintaining the flexibility to integrate with all networks both legacy
and next-generation will become a precondition to growth and success in this age of
evolution.
A NEW MINDSET
The key to the second question how service providers can take advantage of
this changing landscape goes beyond infrastructure issues. To succeed in an age of
converging networks and changing subscriber expectations, service providers must alter
their mindset. They will have to shift from an old world business model that
is infrastructure driven to a new world business model that is service driven.
After all, subscribers dont buy switches, platforms, and software; they buy
services.
To compete and win in the new millennium, service providers must break through the
traditional barriers separating networks, protocols, and technologies to deliver a new
generation of converged voice/data services. Service providers will have to make these
services available to subscribers via the device of their choice from wireless and
landline telephones to PCs and personal digital assistants (PDAs).
A NEW ARCHITECTURE
These market realities are driving the emergence of a new, IP-based enhanced
services architecture that delivers on the promise of network convergence. Unlike legacy
platform architectures, this next-generation service architecture is designed
to support data-centric IP services; IP control protocols such as the media gateway
control protocol (MGCP) and other related open standards, enabling integration with
a wide variety of networks and switches, including the latest programmable soft
switches. Support for CompactPCI hardware, another open standard, provides the
carrier-class redundancy and reliability required by network service providers.
A key aspect of this new architecture is a high degree of modularity, essential in an
age of rapid evolution. Unlike the monolithic software architecture of existing enhanced
services platforms, the new IP architecture employs a layered approach. The
middleware software layer, residing between the application and the underlying
operating software, acts as the translator, handling network interface and
media conversion tasks. Because the middleware is independent from the rest of the
software architecture, it allows modification and extension of the service-enabling
software without a major forklift of the underlying platform software. This
allows for much faster time-to-market and lower cost for innovative, new service
capabilities.
This next-generation IP services architecture offers greatly reduced up-front cost, and
virtually limitless scalability, with very linear scaling costs. These will be critical in
the new marketplace, where the emphasis will shift from mass market services
to highly customized services tailored to individual market segments. With an IP services
architecture, service providers can pilot service offerings in small deployments, then
scale up their deployment as their subscriber base grows rapidly, cost-effectively,
and without any interruption in service. Best of all, this IP enhanced service
architecture offers an ideal solution for the converged network environment of today,
while offering a clear migration to the pure IP network environment of tomorrow.
SINGLE ACCESS POINT
An innovative architecture is only valuable if it provides services that
subscribers want. Todays emerging IP enhanced services meet this requirement,
setting the stage for a whole new generation of converged applications. These
next-generation IP enhanced services leverage network and media convergence to add a new
dimension of convenience, versatility, and value to personal communications.
The flexibility of the next-generation IP enhanced services architecture eliminates the
network centric communications model that requires subscribers to make
multiple calls to access different networks. Service providers can now offer their
subscribers a single, versatile point of access for all of their communications in all
media using any device. The IP enhanced services middleware seamlessly translates across
different networks and, with sophisticated media conversion technology, across different
media.
This access point is highly customizable, enabling both service providers and
subscribers themselves to provision the account to meet personal needs and preferences.
Subscribers can configure, control, and provide filtering capability for their messages
via the Web. They can log in to their personal account and select the messages
voice mail, e-mail, or faxes they want to receive on their mobile phone while
traveling, storing any remaining messages in their voice mail or e-mail account for later
retrieval via a personal account.
INNOVATIVE SERVICES
The market potential of todays emerging IP enhanced services becomes
apparent when you consider the capabilities they deliver, including:
Voice-Activated Voice E-mail
Allows subscribers to originate and send e-mails and to have inbound e-mail
read to them using any telephone device. Through a telephony user interface similar to a
voice mail system, users log on to the service and speak the name of the person to whom
they want to send an e-mail. Using advanced speech recognition technology, the enhanced
services system recognizes the spoken name from a contact directory and creates an e-mail
with the appropriate e-mail address. The user then records a voice message (much as they
would with a voice mail application), that is converted into a compact sound file,
attached to the e-mail and mailed out to the recipient. The recipient can listen to the
message using any standard PC with sound capabilities and a standard e-mail client. Once
the recipient has heard the message on their PC and replied back with text, the enhanced
services platform then converts the text to voice using text-to-speech technology, which
can be easily listened to on any telephone.
This application adds a new dimension of freedom and convenience to e-mail
communications. No longer a text-based, PC-centric medium, e-mail becomes a flexible
communications tool accessible from anywhere at any time.
Unified Communications
An IP-based access point, unified communications provides
subscribers with consolidated, one-stop access to all messages voice,
fax, and e-mail from multiple telephone lines and e-mail accounts. This greatly
simplifies message management, avoiding the need to dial in to multiple mailbox accounts
to review messages. High on the wish list of mobile professionals, unified communications
gives users the ability to monitor their corporate and personal voice, e-mail, and fax
messages from far-flung locations during a single session, using the access device of
their choice.
Internet Event Alerting
Satisfies the growing demand for intelligent notification of activities and
events on the World Wide Web. Examples include: Stock price or trade activity; e-commerce
events, such as a sale or auction bid update; or other events, such as a plane arrival or
traffic alert. The possibilities are essentially limitless. An inbox assistant
on the IP services platform lets each subscriber create a personal profile, configuring
the service with specific event types and notification styles. In this way, the service
turns the vast content of the Web into a valuable, personalized information resource.
TRANSPARENT ACCESS
A key advantage of all these IP enhanced service examples is their transparent
mediation among networks, message stores, devices, and other infrastructure variables.
Giving subscribers easy access to all their communications through a variety of devices
including their personalized contact database will be a prerequisite to
success in the near future.
Support for the very latest device protocols, including the Wireless Application
Protocol (WAP) and the Voice eXtensible Markup Language (VXML), enables subscribers to use
next-generation, browser-equipped wireless handsets to perform a variety of tasks
from checking stock quotes to researching a client while on the move. For service
providers, the modularity of the IP enhanced services architecture opens up opportunities
for the development of even more exciting access devices and technologies yet to be
revealed, such as the portable videophone.
FUTURE VISION
Cosmic predictions notwithstanding, the future of telecommunications services is
evolving right before our eyes. Despite the dynamic nature of that future vision, a few
things are clear. To compete and win in the new era, service providers will need to
dramatically reduce the cost and time-to-market factors associated with subscriber
services. They will need to broaden the capabilities of those services to enable easier
access to multiple accounts, messaging stores, and Internet and corporate intranet
resources. And they will need to adapt to the needs of their subscribers, instead of the
other way around.
Todays next-generation IP enhanced services architecture offers a flexible,
low-cost solution that satisfies these requirements. It gives service providers of all
types from ILECs and CLECs to ISPs and cable providers the tools they need
to move beyond commodity voice and data services to offer the exciting converged
subscriber services needed to be profitable in the new era. c

Adding To The
Palette Of Carrier Services BY JEFFREY PAINE
With long-distance rates dropping through the floor consumers are making calls
for a nickel a minute, corporations for as little as two cents price is no longer a
major factor in the competition among carriers. Instead, carriers will battle it out on
the basis of the differentiated services they offer. The bottom line will be the speed and
flexibility with which they can create and deploy new enhanced voice services across both
circuit-switched and IP-based networks.
Application service creation environments (SCEs) allow just this. Using service
creation tools, new-world carriers and incumbents alike can design and customize services
such as prepaid phone cards, unified messaging, and multimedia applications. However, to
be useful in the rapidly evolving communications arena, these tools must be accessible,
easy to use for quick service development/deployment, and functional for both voice and
VoIP networks (transport independent) and for a variety of vendor switches (platform
independent).
Traditional Intelligent Network (IN) service creation tools do not meet these
requirements. Creating a specialized service is development-intensive and time-consuming.
A complex feature such as caller ID screening (i.e., if a callers ID is
unavailable, an intermediary answers the call, takes the callers name, calls the
destination and announces the caller) can take months of coding and testing with typical
IN tools. And the providers themselves, generally lacking the expertise to handle such
projects, are dependent on costly telco equipment provider outsourcing.
Furthermore, any modification or customization of services with IN tools is constrained
to a fixed set of call models and trigger points. Created originally for use with voice
traffic, these tools are only minimally adaptable to data use, falling short when used for
such applications as multimedia or unified messaging. With the advent of IP-based
voice/data infrastructures, the limitations in functions, granularity of capabilities,
flexibility, and development time are even more critical. And, perhaps most important,
todays IN tools were designed to be embedded in switch platforms, tying the user
inextricably to specific hardware solutions.
THE SCE COMPROMISE
A wholly new SCE that suits both the PSTN and Internet telephony infrastructures is
needed. Such an SCE would eliminate the cumbersome coding and re-coding process and
the users dependency on the tools vendor providing user-accessible tools that
offer a virtually unlimited range of mix-and-match service scenarios. For example, with a
palette of shapes or objects representing states, events, and functions, a user could
simply drag and drop objects into place in a graphical call flow layout to create any
combination of services desired. The look and feel of this user interface could be
provided by a familiar and inexpensive software package such as Visio.
Objects in the palette could be deployed in almost limitless combinations. For example,
with a few mouse clicks, the user could speech-enable his messaging application
(press or say one to reach an operator); enable online recharging
of prepaid phone cards; or, for one-number follow me service, choose to ring
multiple phones simultaneously or in sequence, answer the call and take a message, or
answer only when the person is located.
Whereas IN tools were created specifically to manipulate large Class 5 switches from a
few vendors, the new SCE model takes advantage of an emerging concept known as a
softswitch, which moves call control onto servers external to the switch.
Facilitated by the emerging Media Gateway Control Protocol (MGCP) standard, the new SCE is
transport- and platform-independent, and thus interoperable with multi-vendor switches and
voice/VoIP networks. All actions are executed via standard APIs between the softswitch and
the various switches, databases, media resource servers, etc. The new softswitch-based SCE
can help keep carriers competitive by giving them the unprecedented ability to quickly and
continuously deploy differentiated services.
