Alcatel-LucentMobile EvolutionTransport Architecture

Enabling the ProfitableEvolution to All-IP

2 Alcatel-Lucent Mobile Evolution Transport Architecture

The mobile market is changing, and to remain competitive, mobile

service providers and backhaul transport providers must deliver new

services at lower cost. Mobile user demand continues to move beyond

basic data services like instant messaging and email to more delay

sensitive applications like streaming media and real-time multimedia.

In response, broadband wireless technologies including high-speed

packet access (HSPA) and evolution data optimized (EV-DO) are

evolving to enable even higher transmission speeds and packet

interfaces. Mobile transport networks must evolve to meet these new

bandwidth demands and support 3G and 4G (LTE & WiMAX) mobile

services profitably.

Mobile Transport Networks Under Pressure

As more subscribers begin to adoptadvanced, bandwidth intensive mobiledata services, existing backhaulnetworks based on leased lines arestrained to cost-effectively deliverincreased capacity. As a result,service providers are challenged toevolve mobile transport networksto accommodate new packet-basedservices while simultaneouslysupporting traditional services.

As this evolution to packet occurs, service providers mustmeet or exceed the quality of experience that subscribersexpect from voice, video, and data services. To do so, theymust leverage existing network infrastructures and simul-taneously transform their mobile transport networks tosupport packet-based traffic.

To meet business objectives and user demands, mobiletransport networks must:

• Support new multimedia and current services (2G/3G)while preparing for the introduction of LTE

• Enable scalable bandwidth at lower cost (leveragingEthernet/IP over multiple media: copper, fiber, microwave)

• Provide service assurance across all services (via carriergrade Ethernet/MPLS)

• Lower operations costs (via integrated management)

With this comprehensive approach,both mobile service providersand backhaul transport providerscan cost-effectively transform theirbackhaul infrastructure fromTDM/PDH to packet over copper,fiber or wireless at their own pace.


The Alcatel-Lucent META end-to-end architecture, spanning from cellsite to core, enables service providersto simplify operations via integratednetwork and service management. Inthis way it:

• Provides flexibility and scalabilityto support new, profitable 3Gand 4G (LTE & WiMAX)mobile services

• Provides QoS support for all mobileservices, efficiently allocating scarcenetwork resources in real time

• Increases network optimizationand capacity, improving cost perbit transported as leased linesare replaced

• Addresses infrastructure diversity viaflexible backhaul alternatives, eachproviding an evolution to all-IP

Flexible Options forCustomized Transformation

Alcatel-Lucent META is designed togive service providers complete con-trol over their network transformation.It can be tailored to meet diversetransport network strategies whetherfollowing a hybrid data offloadapproach or converging all servicesonto an IP-RAN.

Alcatel-Lucent META interworkswith IP/MPLS and optical backbonesto meet the reliability and servicescaling requirements of next genera-tion networks (NGN), IP multi-mediasubsystems (IMS) and IP-based serv-ices. By using a service router ortransport service switch in the MTSOto interconnect mobile elements,service providers can optimizeresources and networking flexibilityof inter-element connections todrive costs out of the radio accessnetwork (RAN). Furthermore, byusing a service router combining the

functions of an edge router and aMulti-Layer Switch (MLS), CDMAservice providers can deploy a cost-effective and flexible solutionrequiring fewer devices whilepreparing the network for furthermobile transport evolution.

Additional flexibility is provided byallowing service providers to takethe capabilities of service routingand Carrier Ethernet transport tointermediate hub locations in theRAN. This allows a common, sharedinfrastructure to be used for allaggregated traffic between the huband the MTSO. It also deliverssignificant leased line savingsbecause Carrier Ethernet or opticalconnections can be used for backhaul.

In areas where no fiber is available atthe cell site, service providers canutilize Ethernet enabled microwaveaccess. This provides a quick andeconomical backhaul alternative,such as in the case of WiMAX basestations. Ethernet enabled microwaveaccess and aggregation capabilitiesoptionally built into Alcatel-LucentWiMAX base stations provide areduced footprint, optimized layoutand cabling, faster installation time,and verified interoperability.

Through the implementation ofCarrier Ethernet between the cell siteand the MTSO, traffic can be aggre-gated efficiently and end-to-endservice delivery upheld. For serviceproviders evolving to packet-based backhaul, the combinationof both Ethernet for reduced costsand MPLS for enhanced servicesdelivery with reliability and QoSare essential to support all mobileservices.

The Alcatel-Lucent META can alsosupport multi-generational access viasimultaneous support for TDM/PDH,SONET/SDH, multilink point-to-point protocol (MLPPP), ATM withATM Inverse Multiplexing (IMA),Ethernet and IP as the accessnetwork evolves.

By supporting a variety of RAN trafficaggregation and backhaul technologiesAlcatel-Lucent META enables costeffective transport of 2G/3G trafficwhile preparing the network forevolution to LTE.


Alcatel-Lucent META provides additional benefits by extending IP/MPLS,MPLS-TP and Ethernet aggregation towards the cell site. In the cell site thereare opportunities for aggregation solutions that converge multi-generationaltraffic streams and/or adapt legacy base station interfaces onto packet transportinfrastructures. Addressing a wide range of access alternatives, these includethe 7705 SAR-F, 1850 TSS-5, or 9500 MPR. Additionally these solutions canhelp service providers by linking small clusters of base stations and groomingthe traffic to reduce backhaul costs.

Multiple first mile transport options exist to transport traffic between thecell site and a hub. These include: DSL, GPON, fiber and microwave connec-tions. DSL provides a connectivity solution for the first mile where opticalfibers are not available but copper pairs are. For base stations having opticalfiber available, GPON provides the connectivity solution for backhaul.Both the DSL and GPON solutions leverage the deployments fortriple play services to backhaul mobile traffic. The clock delivery capabilitiesof these solutions allow TDM/ATM leased lines to be completely replaced.


Leveraging ExistingInvestments, Ethernet and MPLS

The goal of mobile transport networkmodernization is to enable newservice delivery while lowering thecost of transport. Alcatel-LucentMETA leverages the optimal costpoints of newer transport technolo-gies including Carrier Ethernet andMPLS to help service providersprepare for the profound changesthat long term evolution will bring.

A key component of the architectureis a packet-optimized, data-awaretransport infrastructure suitable forthe full range of legacy and newservices. This infrastructure willneed to support different QoSrequirements (i.e., delay),depending on the application.

Multiple QoS Requirements

To meet the stringent QoS requirements of real-time traffic,the mobile transport network must integrate many of thequalities and attributes of switched networks: predictability,reliability and manageability. The implementation ofMPLS/MPLS-TP within the Alcatel-Lucent METAprovides the QoS, traffic engineering and managementcapabilities necessary to support all mobile services aswell as business applications and consumer Internetservices over an IP network.

Rather than using multiple overlay backhaul networks,Alcatel-Lucent META can accommodate legacy accessneeds and be optimized for next generation broadbandservices using Ethernet and MPLS, based on multi-servicerouting and switching platforms. The use of IP/MPLS-basedpseudowires brings mature and efficient functionality to theRAN and enables transition of the legacy RAN to packet.Likewise, the incorporation of Circuit Emulated Service(CES) capabilities onto transport service switches allowsoperators to leverage existing TDM investments byenabling the transport of TDM traffic over Ethernet.

Integrated Network and Service Management

The mobile RAN and transportnetwork is characterized by rapidgrowth as well as a diversity of accesstypes. As mobile networks grow, acontinuous rebalancing of the RANand transport network can have amajor impact on the cost of networkownership, as the network is modifiedto accommodate changes in capacityrequirements. To support this criticalbusiness activity, strong networkmanagement tools and processes areneeded to control operating expenses.

Network management in the Alcatel-Lucent META is provided by theAlcatel-Lucent 5620 managementportfolio supporting Alcatel-Lucent’sconverged IP, Ethernet and MPLSportfolio inclusive of cell sites havingmicrowave access via the Alcatel-Lucent 9500 Microwave Packet Radio(MPR). As part of this portfolio, the5620 Service Aware Manager (SAM)enables provisioning of an end-to-endservice using wizards or point and-clickconfiguration from a single applicationwithout having to individually con-figure each device in the service path.It greatly reduces the complexity andrisk associated with provisioningcomplex services, and provides com-prehensive support for fault, config-uration, accounting, performanceand security.

The management system of a trans-formed mobile transport network musthave the capability to understandthe hierarchy of end-to-end serviceconstruction. With this service aware-ness the management system canreact to individual nodal and compos-ite service events and present corre-lated, relational information tothe operator. This enables fasterservice provisioning, verificationand restoration.

Management of optical and micro-wave transport systems in the Alcatel-Lucent META is provided by theAlcatel-Lucent 1340 IntegratedNetwork Controller (INC) and 1350Optical Management System (OMS),a comprehensive set of applications,bundled according to the transportnetwork solutions managed (e.g.,connectivity services based on Ethernet,MPLS-TP, SDH/ SONET, and WDMtechnologies). This complete solutionallows mobile service providers andbackhaul transport providers tomanage multi-technology, multi-service networks that integrate currentand next-generation transport techn-ologies with emerging data traffic likemetro Ethernet.
