The Challenges 3G faces in Satisfying Growing Demand for Mobile Data

3G Challenge BSR Solution

Flat architecture, licensed spectrum and end-to-end QoS

support

Integration of network elements reduces latency by about 40%

Adding BSR requires minimal network reconfiguration and

expenses and helps relieve the strain on the macro network.

Eliminates network elements. Takes advantage of lower cost

backhaul (i.e. xDSL or Ethernet)

Cumbersome end-to-end QoS Impact: IP Voice Services

High Latency Impact: Service & End User

ExperienceDifficulties to respond quickly to changing capacity and market

needs Impact: In-building coverage,

Time to marketHigh OPEX/CAPEX

Impact: High backhaul and maintenance costs. High

RNC/OAM costs

Uncertain 3G Data Value Proposition

Impact: Operator Profitability

Optimized for delivery of IMS-Based applications

Operator Challenges… Alcatel-Lucent’s BSR Solution

Simple installation by user, auto-configuration process. Secure web-based user registration

Eliminate installation site visits. Need out of box solution with remote support

Patented self-optimisation & power control process. Automated and continuous monitoring of neighbours

Impact on RF network and cell planning. Minimize macro network interference, maximize coverage

Flat IP architecture. Virtual RNC structure. Standard interfaces. Few integration points

Complexity of integrating into existing network. Simple and scalable addition of large numbers of units into network

Low cost self-configuring units. Flat IP architecture Standard interfaces. Integrated self-help databases

Operational cost of new additions to network. Eliminate all manual operator intervention

Flexible tariff profiles. Secure web user database integrated with HLR

Charging flexibility. Separate tariffs for homeowners, visitors, roamers, sharers

Home BSRs appear as virtual NE, either RNC or SGSN. Full seamless 3GPP mobility with macro layer possible

Mobility management. Effective control whilst minimising signalling traffic

New flat IP architecture. Compatible with & can appear like existing network

Impact on macro network. Traditional network architecture does not support plethora of consumer access points

Full end-end encryption achieved on both signalling and data planes

Security. Maintaining secure pipes for all elements

Direct routing of BSR – BSR traffic. Router offloads high volume, low value internet traffic

Reduce core network traffic. Offload local and internet traffic

Free standing or wall mounted

Consumer lifestyle convenience – one home multimedia access point,one bill

Supports any 3GPP UMTS terminal

Up to 4 users (R99, HSxPA or CS)

Enables converged service bundle

Increasing revenue opportunity

Reducing churn (stickiness)

Offloads traffic from macro layer

DSL backhaul

Improves coverage and quality of service

Wider Advantages of BSR Architecture

BSR integrates all of this into a

single box

•BSR-Femto

Future-proof technology innovation Simplifies evolution to IMS and LTE.

Capex, Opex optimization Centralized aspects confined at IP layer for lower scaling cost

Lower latency due to flat IP architecture Fewer bottleneck nodes as traffic is offloaded

BSR Provides Advantages Over WiFi

Greater ability to control security and quality of service

Operator controlled spectrum

Less likely to have interference from competing unlicensed networks

Comparable speeds via HSDPA/HSUPA

Mobility

No need to integrate separate WiFi and UMTS networks

Standard UMTS mobiles

Easier to implement simplified data user plans for end users

No need for separate bills, separate accounts or different sign on procedures

RF Considerations in BSR-Femto deployments

•BSR-Femto uses patented auto-configuration and

self-optimisation algorithms

•BSR-Femto uses bare minimum Tx power to support QoS

•Can operate on the same carrier as the macro layer

•BSR-Femtos in close proximity to each other, even co-channel, do not

degrade each

other’s performance

•With separate carriers, no negative effects are seen in the macro or femto

layers
