Alcatel-Lucent Mobile Backhaul Solution

Enabling the Profitable Evolution to All-IP

Alcatel-Lucent Mobile Backhaul Solution2

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) mobile services profitably.


Alcatel-Lucent Mobile Backhaul Solution 3

As more subscribers begin to adopt advanced, bandwidth intensive mobile data services, existing back haul networks based on leased lines are strained to cost-effectively deliver increased capacity. As a result, service providers are challenged to evolve mobile transport networks to accommodate new packet-based services while simultan-eously supporting traditional services.

As this evolution to packet occurs, service providers must meet or exceed the quality of experience that subscribers expect from voice, video, and data services. To do so, they must leverage existing network infrastruc tures and simul-taneously transform their mobile transport networks to support packet-based traffic.

To meet business objectives and user demands, mobile transport networks must:

• Supportcurrent2G/3Gserviceswhileprovidingthescalabilityandflexibilitytosupportnew4G/LTE mobile services

• Enablescalablebandwidthatlowercost(leveragingEthernet/IPovermultiplemedia:copper,fiber,microwave)

• Provideserviceassuranceacrossallservices(viacarriergradeEthernet/MPLS)

• Deliveraccurateclocksynchronizationmechanisms to converge rapidly across the packet radio access network(RAN)

• Loweroperationscosts(viaintegratedmanagement)

IntegratedNetworkandServiceManagementThemobileRANandtransportnetworkischaracterizedbyrapidgrowth as well as a diversity of access types. As mobile networks grow, a continuousrebalancingoftheRANand transport network can have a major impact on the cost of network ownership, as the network is modified to accommodate changes in capacity requirements. To support this critical business activity, strong network management tools and processes are needed to control operating expenses.

The management system of a trans-formed mobile transport network must have the capability to under stand the hierarchy of end-to-end service construction. With this service aware-ness the management system can react to individual nodal and compos ite service events and present corre lated, relational information to the operator. This enables faster service provisioning, verification and restoration.
