Introduction

Wireless fidelity (WiFi) walks the line between fixed and mobile. Metro Ethernet muddies thewater between local area network (LAN) and WAN. Is collaboration a communications tech-nology or a desktop application? The lines continue to blur. Obviously, these changes affectthe capabilities available to enterprise users in a dramatic and positive way. Equally importantlyhowever, they profoundly challenge traditional deployment scenarios and business models. As

the lines between technology domains fade, so the boundaries between enterprise user andresidential user, between enterprise and service provider, or even between different serviceproviders, become more flexible.

Several capabilities that could until recently only be delivered by local premises-based solu-tions can now be more effectively delivered from a hosted location inside a service-providernetwork in fact, as we will see, for some mobility-related services this is the only practicalapproach. These dramatic changes in the telecommunications application architecture drivenew complementary requirements into the network and security infrastructure. At the sametime, the increasing complexity of the enterprise communications environment is pushingenterprises to consider alternative, simpler, more cost-effective approaches that enable themto better focus on their core businesses.

Alcatel-Lucents holistic solution for delivering Managed Communications (MCS) enables serviceproviders to meet these new challenges and opportunities in the enterprise market. It funda-mentally recognizes that enterprise solutions will include both network- and premises-basedelements in whatever is the most appropriate combination for a particular organization.It also recognizes that service providers will take many forms be they telecommunicationsoperators, systems integrators, application service providers or the internal service providerof a large enterprise.

Managed Communications and Enterprise Transformation

What each of these service-provider categories has in common is that they face a transforma-tion in enterprise information and communications technology (ICT). This transformation isdriven by an unprecedented number of major technology changes occurring at the same time.Fundamental changes in broadband network technology, combined with new, application-enabling technologies such as IP multimedia subsystem (IMS) and web services, are revolution-izing what is possible in terms of services, from versatile managed networking services topresence-based mobile collaboration and conferencing, through to advanced service-chainmanagement and business-process integration.

At the network level, service-aware networking enables broadband technologies such as carrierEthernet, high-speed any DSL and passive optical networking (PON) to provide the customer-specific quality of service (QoS) and security required to deliver truly sophisticated location-independent enterprise applications. To deliver those applications in a consistent way betweenfixed and mobile networks, IMS provides a common session-control architecture includingsupport for global roaming between different mobile service providers. At the same time, usersmoving around inside enterprise premises have a compelling new access alternative in the formof dual-mode cellular/WiFi phones. This is strategically significant, because approximately one-third of mobile phone calls today originate inside the home or work premises, not to mentionthose from WiFi-enabled cafs, airports, train stations and so forth.

Overlaid on this increasing flexibility of access are fundamental changes to how we will initiatecommunications and integrate communications into our business processes. Historically, phonecalls have been initiated by dialing a phone number, but this dialed number paradigm is givingway to a click-to-call model of presence-based communication initiation, where the user simplyclicks on a name from a buddy list or directory to place a call. Both service providers and enter-prises will need to accommodate the complexities of this migration, including the integrationof existing intelligent network (IN) and private branch exchange (PBX) infrastructures.

In parallel we will see the end of the mobile island, as mobile handsets become full participantsin the enterprise telephony and IT environment. That means that users can have a singlenumber, a single contact list, a single voice mailbox, consistent features across their desk andmobile phone, and access from anywhere to advanced applications such as conferencing andcollaboration. Similarly, the sophisticated intelligence applied to customer interactions needsto move out of the physical constraints of the call center, to be available to anyone who formspart of the service chain involved in serving customers.

MCS Challenges

The increasing complexity of the enterprise environment offers real opportunities to differentiatestrongly through the cost-effective delivery of compelling, reliable, secure MCS services. Butin order to execute that vision, service providers must overcome key challenges.

Build the right foundationsA service-aware packet network offering managed enterprise virtual private networks (VPNs),combined with appropriate broadband business-access services, not only enables high-valuemanaged networking services with rich customer self service, but also provides the secure,QoS-capable IP transport that underpins other MCS services. An additional benefit for IPtelevision (IPTV) service providers is that MCS can share a common network infrastructurewith Alcatel-Lucent-based triple play services, with appropriate extensions to encompassmobile networks.

Enable the mobile enterprise todayDriven by the impact of WiFi, mobility is the area of greatest change and opportunity forenterprises. What is a mobile enterprise? It is an enterprise where users are as productiveas possible wherever they are which means consistency of service, regardless of deviceor location. To realize that goal, an MCS solution must provide tight integration of circuit-switched and IMS mobile phones with a broad range of existing premises solutions (includingdirectories, messaging, presence servers and PBXs). The ability to use a single phone is abeginning, but an effective mobile enterprise needs more a true unified communicationssolution that provides simplification of phone numbers, contact lists, messaging and bills.

Deliver compelling applicationsObviously, it is not sufficient to simply add mobility to the existing telecommunications para-digm, when that paradigm itself is changing. The move to presence-based call initiation isdriven in the enterprise by conferencing and collaboration applications. At the same time,the extremely sophisticated call-routing capabilities of the contact center, combined withmobility, promise to revolutionize the rest of the service chain. The technology challenge isnot only to deliver such applications consistently via premises-based and hosted deploymentmodels, but also to ensure that such solutions can both deliver standalone services, andelegantly add value to any third-party applications that an enterprise wishes to use.

Provide value and visibilityThe service provider must clearly articulate why MCS is a more attractive proposition thanan enterprise doing it themselves. Beyond the service offerings, the business case must also becompelling. Fortunately, MCS can offer economic advantages both in terms of deploymentflexibility the ability to mix network and premises-based solutions to optimize costs aswell as the flexibility of pay-as-you-go contract options. However, value for money alone isnot enough. Alcatel-Lucent and third-party research consistently shows that visibility and

control are also significant enterprise considerations that service providers must address.

Optimization and innovationHow does a service provider industrialize its MCS service offerings so that costs are optimizedwhile ensuring rapid deployment of new services? Key considerations in optimizing costs area smooth migration to IMS which helps optimize the timing of major network investmentsin both fixed and mobile and a reduction in systems complexity through adopting an SOAbased on web services. The good news is that these same technologies also provide the bestmechanisms to speed up the delivery of new services, by simplifying service innovation andstreamlining the service-creation process.

The Alcatel-Lucent MCSDATo help service providers meet these challenges, we have developed the Alcatel-LucentMCSDA a reference architecture that describes network, service delivery, managementand support-systems capabilities as an integrated solution for delivery of compelling MCS.The key design goals of the Alcatel-Lucent MCSDA directly address the challenges facedby service providers:

Provide rich customer self-service that fully leverages network capabilities

Service-aware IP/multiprotocol label switching (MPLS) networking offering QoS-enabledpremium Layer 2 and Layer 3 business VPN services with strictly enforced service levelagreements (SLAs)

Integrate tightly with both IMS and circuit-switched network control thereby providinga smooth migration to IMS, without constraining network choices

Sophisticated interoperation between mobile phones and a broad range of premisessolutions

A complete, unified communications solution for all enterprises including mobile users

Conferencing and collaboration that works with or without premises solutions

Create dynamic contact centers that maximize customer-service quality and revenuegeneration

Deliver consistency of user experience, regardless of deployment model

Leverage SOA to reduce integration complexity and rapidly deploy new services

Comprising several functional domains, the Alcatel-Lucent MCSDA is unique in that itoffers an integrated, end-to-end view of network, service-delivery and support systems, seeFigure 1.

Figure 1. High-level Alcatel-Lucent MCSDA

Applications that deliver end-user services share service enhancements such as profile, presenceand policy servers with the applications for service operations including fulfill, assure, billingand self-service.

When hosted in a service-provider network, this application environment is based on theAlcatel-Lucent Carrier-Grade Delivery Environment (CG-SDE), which ensures a commonarchitectural approach across different Alcatel-Lucent solutions. However, consistent withthe Alcatel-Lucent MCSDA goal of deployment flexibility, it is important to emphasize thatthe application environment need not be fully hosted it may equally be partially or fully

deployed in enterprise data centers or other enterprise-premises locations.

The application layer supports the delivery of MCS services across different session-controlmechanisms including session initiation protocol (SIP)/IMS and circuit-switched. These inturn share a common IP transport leveraging service-aware routing across a variety of broad-band business-access services that terminate on a premises gateway or customer premisesequipment (CPE) appropriate to the combination of premises type and MCS service.

Building the Right Foundations

The Alcatel-Lucent MCSDA is able to deliver not only the secure, QoS-enabled IP transportrequired by application-level services, but also sophisticated Layer 2 and Layer 3 managednetworking services with rich customer self-service, see Figure 2. Service providers offeringAlcatel-Lucent Triple Play solution services may leverage a common service-aware networkfoundation for the economical delivery of both residential triple play and business services

Alcatel-Lucent is leading the industry in service routing and switching solutions, offering productsthat are purpose-built for service-oriented Layer 2 and Layer 3 VPN solutions, including carrierEthernet VPNs using virtual private LAN service (VPLS) and Layer 3 premium IP-VPNs.Independent tests have validated operation of this architecture with 43,000 enterprise classLayer 2 and Layer 3 VPN services operating simultaneously with 500 TV channels to 120,000triple-play subscribers.

Service edge functions are delivered by a combination of the Alcatel-Lucent 7450 EthernetSwitching System (ESS) (for Layer 2 services) and Alcatel-Lucent 7750 Service Router(SR) and Alcatel-Lucent 7710 SR (for Layer 2 and Layer 3 services). The Alcatel-Lucent7450 ESS and Alcatel-Lucent 7750 SR provide always-on services, with restoration arounda link failure in less than 50 ms using MPLS fast reroute, and recovery in milliseconds froma control-plane failure.

More importantly, this architecture delivers per-customer QoS at the service edge where itscales. An MPLS core provides hard QoS, providing deterministic service guarantees.

However, the Alcatel-Lucent MCSDA takes this further by leveraging hierarchical sched-uling, which allows service providers to prioritize different services such as VPLS andInternet access over the same physical connection, and combine them into one overallSLA. Such capabilities enable meaningful per-site service-level controls and service-levelreporting through a high-value customer self-service portal. The value that can be deliveredthrough the portal is directly related to the capabilities of the network. It is critical not tounderestimate the importance of this element 90% of IT executives consider real-time

visibility and control to be an important factor when selecting a managed networking service.

But how can a service provider ensure that these capabilities are available to the widest possiblegeographic coverage? While the Alcatel-Lucent 7450 ESS, Alcatel-Lucent 7710 SR andAlcatel-Lucent 7750 SR can directly support Ethernet leased lines, in situations where con-nectivity is required towards traditional PDH leased lines, the Alcatel-Lucent 1850 TransportServices Switch can support both PDH and Ethernet from the same platform. This providescost-effective physical aggregation, while connecting towards the Alcatel-Lucent 7450 ESSand Alcatel-Lucent 7750 SR service-aware elements as a spoke in a hierarchical VPLS cloud.Similarly, the unique IP features of the Alcatel-Lucent 7302 Intelligent Services Access Manager(ISAM) family extend service intelligence across diverse access architectures including DSL

technologies (e.g., ADSL2plus and very-high-data-rate DSL [VDSL2]) and deep fiber deploy-ments (e.g., fiber to the node [FTTN] and PON). In many cases it is also necessary to supportinterworking with existing frame relay and ATM services as users gradually migrate to Ethernet/MPLS, which is achieved using the Alcatel-Lucent 7670 Routing Switch Platform (RSP).

Finally, at the customer premises, the Alcatel-Lucent MCSDA leverages Alcatel-Lucentpremises solutions (such as the Alcatel-Lucent OmniSwitch 6200/6850 and Alcatel-Lucent7250 Service Access Switch) to provide an integrated, end-to-end managed networkingservices solution supporting multiple access types with rich customer self-service.

Enabling the Mobile Enterprise

Prompted in part by the emergence of WiFi and dual-mode phones, enterprise managers areincreasingly looking at how mobile solutions can improve business performance, and how mobilephones will interact with the rest of the enterprise telecommunications environment.

In an all-IP world, SIP provides an elegant path to achieve this integration between mobilephones and enterprise applications. As illustrated by circle (1) in Figure 3, SIP-based sessioncontrol inherently enables fixed and mobile devices to share the same applications loweringcomplexity and improving the consistency of the user experience. For fixed and mobile serviceproviders, the Alcatel-Lucent MCSDA specifies an IMS core based on the Alcatel-LucentSession Manager.

However, in parallel with the deployment of IMS, many users (especially mobile phone users)will continue to be supported by circuit-switched networks for some time. There are two dif-ferent mechanisms for support of circuit-switched devices by a common application environ-ment: either the use of media gateways (e.g. the Alcatel-Lucent 7510 Media Gateway [MG]and Alcatel-Lucent 7515 MG) to control the circuit-switched network via an SIP/IMS inter-face on the application server; or direct support of both SIP/IMS and circuit-switched (IN)interfaces on the application servers themselves, as illustrated by circle (2) in Figure 3. In theAlcatel-Lucent MCSDA, relevant applications such as the Alcatel-Lucent 8640 CorporateMobility Manager (CMM) support both approaches. This unique flexibility is important,because there are significant differences in network economics between the two approaches,depending on the specifics of a particular service provider.

Figure 3. Enabling the Mobile Enterprise

Another area where the Alcatel-Lucent MCSDA provides engineering flexibility is in thechoice of mechanisms for session continuity that is, the ability to continue a session when

moving between WiFi coverage and cellular coverage (primarily in the case of dual-modephones). For example, for an Alcatel-Lucent 8640 CMM virtual PBX (VPBX) user, sessioncontinuity could be provided at the network level via unlicensed mobile access (UMA) utilizingjust the customized application mobile enhanced logic (CAMEL) interface on the Alcatel-Lucent 8640 CMM the UMA phone appears just like a regular Global System for MobileCommunications (GSM) phone to the Alcatel-Lucent 8640 CMM VPBX. Alternatively(and more commonly with Alcatel-Lucent 8640 CMM deployments), session continuity isperformed at the application level by the Alcatel-Lucent Intelligent Mobile Redirect Solution(IMR) module, running alongside the VPBX module on the Alcatel-Lucent 8640 CMM. Inthis case, both the SIP and CAMEL interfaces on the Alcatel-Lucent 8640 CMM are used(for WiFi and circuit-switched cellular access respectively), and the Alcatel-Lucent IMR

module handles the session continuity. A similar application-level solution is available forpremises-based deployments (the Alcatel-Lucent OmniPCX Enterprise Mobility Server).The application-level solutions provide a richer feature set, while the UMA approach can beattractive in terms of its simplicity and the associated speed-to-market advantage for mobileservice providers. Either way, the Alcatel-Lucent MCSDA provides an elegant migration forone-phone services as mobile networks move from circuit-switched to IMS.

The emergence of compelling wireless PBX applications (such as the Alcatel-Lucent 8640 CMMVPBX) means that, for some smaller enterprises, it is no longer necessary to maintain their ownpremises-based PBX. However, for most larger enterprises, that is not a practical option, so thekey question is how to make the mobile phone interoperate seamlessly with the existing premisessolutions including PBX, mail, directories and presence illustrated by circle (3) in Figure 3.

PBX integration presents significant architectural challenges due to the number of differentapproaches available. Protocol suites that can be used for PBX integration include the SIPand related standards for voice over IP; Q-standard image format (Q-SIG), which supportsinteroperation of different vendors PBXs over TDM; and computer telephony integration(CTI) mechanisms. At first glance, SIP or Q-SIG gateways appear attractive in terms of sim-plicity, but they can only support basic features. To deliver the more sophisticated features thatare typical enterprise requirements such as manager-secretary features, ring back when free,

twinning (simultaneous ringing of PBX extension and mobile) it is necessary to use a CTI-based PBX integration mechanism. Because of its broad enterprise portfolio, Alcatel-Lucentcan support each of these PBX-integration approaches.

The ability to work with such a broad range of PBXs is a very strong differentiator for theAlcatel-Lucent MCSDA, and allows service providers to maximize their addressable market.However, in many situations the service provider (perhaps in combination with other channelpartners) will deliver an end-to-end solution combining network-based services with premises-based solutions, such as Alcatel-Lucents OmniPCX Enterprise and OmniPCX Office, forlarger and smaller businesses respectively. In such situations, the Alcatel-Lucent MCSDAensures that an end-to-end Alcatel-Lucent solution delivers an even richer and more con-

sistent user experience, especially for mobile users.

While advanced integration of PBXs is an important strength of the Alcatel-Lucent MCSDA,it is important to emphasize that MCS must go well beyond mobile enablement of the tradi-tional PBX-oriented, dialed-number paradigm of enterprise telecommunications. Instead, MCSservice offerings must anticipate and embrace the revolution in enterprise communicationscaused by a shift to presence-based call initiation. The Alcatel-Lucent MCSDA naturallyincorporates Alcatel-Lucents industry-leading solutions for enterprise mobility, customer careand vertical-market solutions. In fact, the richness of this application environment is arguablythe greatest strength of the Alcatel-Lucent MCSDA. Because it encompasses diverse applications,across the spectrum from rich multimedia collaboration and conferencing to the market-leadingGenesys Contact Center range, the topic is too broad for a single paper the reader istherefore referred to detailed descriptions of each of these application solutions.

Secure Federation in an SOA

Where practical, the Alcatel-Lucent MCSDA leverages web services and SOA. Amongtelecommunications vendors, Alcatel-Lucent is unique in the concrete steps it has taken todeliver on the promise of web services. Firstly, building on initial industry standardizationefforts, Alcatel-Lucent has defined an Alcatel-Lucent Web Services Profile that will be usedon all Alcatel-Lucent web-services interfaces. Secondly, for enterprise services, Alcatel-Lucenthas already defined and implemented a broad set of web-services interfaces that are used bysome 450 application partners to deliver rich, vertically-oriented solutions. These are currently

available on the Alcatel-Lucent OmniPCX and Alcatel-Lucent Unified Communicationssolutions, and will be extended to other elements of the Alcatel-Lucent MCSDA.

Web services are an important part of the Alcatel-Lucent MCSDA integration solution, but byno means the only part. From a telecommunications-architecture perspective, it could sometimesbe tempting to suggest that everything would be simpler if all service enablers were network-based especially profile and presence. And while some enterprises might be attracted tothis approach, the reality is that a majority of larger enterprises will, often for good reasons,maintain their own profile, policy and presence solutions.


13/16


Despite this, the Alcatel-Lucent MCSDA must deliver on the promise of consistency betweennetwork and premises-based deployments. Figure 4 illustrates how a hosted application (e.g.,Alcatel-Lucent 8628 Multimedia Instant Conferencing [MMIC]) using a shared service enabler(e.g., the Alcatel-Lucent 5350 Presence Server) federates information with an equivalent com-bination of service enabler and application in the premises (for example Alcatel-Lucent MyTeamwork, or a third-party solution such as Microsoft Live Communications Server).

Figure 4. Federation Between Hosted and Premises Applications

Conclusion

The Alcatel-Lucent MCSDA brings together a wide range of Alcatel-Lucent capabilities,including many that are unique to Alcatel-Lucent: managed networking services that leverageservice-aware routing; network applications that directly support both IMS and IN protocols;a proven, multivendor premises-integration solution shared across mobile enablement, collab-oration and contact-center solutions; conferencing solutions that offer sophisticated features,either standalone or integrated with third-party solutions; and, most importantly, consistencybetween network- and premises-based solutions, backed up by a huge range of third-partyapplication developers.

What the Alcatel-Lucent MCSDA adds on top of all these unique capabilities is something elseunique to Alcatel-Lucent it encapsulates the very hard work of determining how the differentsolutions fit together to enable enterprise services that are truly compelling and cost-effective.

As with Alcatel-Lucents other end-to-end integrated solutions, that up-front work means thatservice-provider customers can meet the very real new challenges in the enterprise market morequickly, more efficiently, and most importantly more competitively.
