Redefining how 3G networks are built As the roll out of LTE networks accelerates across the world, so flat networkarchitecture is rapidly becoming the norm. Flat architecture for 3G permitsoperators to similarly enjoy many of the benefits realised in LTE networks,offering enhanced subscriber experiences and simplified networkconsiderations. All of which helps operators to meet the rapidly risingdemand from users for mobile broadband with top performance and at evermore competitive prices.

Nokia Siemens Networks Flexi Direct solution brings the advantages of LTEflat architecture to 3G networks. By integrating the Radio Network Controller

(RNC) functionality into the base station of conventional 3G networks, FlexiDirect improves traffic flows and reduces the network’s total cost ofownership.

Standardized and simplified architecture

Flexi Direct technology is standardized in 3GPP Release 7, which ensuresinteroperability with existing 3G core networks and 3GPP terminals. FlexiDirect’s approach means that the base station connects directly to the corenetwork.

The integration of RNC functionality into the base station means thatinvestments can instead be redirected to develop the network in other ways.Investing in Flexi Direct enables a significantly higher number of mobilebroadband subscribers to be served and removes the risk of investmentsbecoming obsolete when upgrading to LTE.

Flexi Direct enables operators to increase 3G network capabilities flexiblywithout the need for RNC upgrades, which also improves networkavailability for end users.

Flexi Direct is smart device and voice call

friendlyIt is well known that smart devices tend to produce huge amounts of dataand signalling traffic, which traditional RNCs need to cope with. Flexi Directwith its embedded RNC functionality supports a practically unlimited numberof smart devices per cell.

The mobile broadband experience is improved through Flexi Direct’s fastnetwork response times, rapid call set-up times and high capacity to meetpeak traffic demands and increased throughput to support more customersusing data-hungry services such as video streaming.

Support for voice is a prerequisite for any mobile network. Based on

Nokia Siemens Networks’ renowned Flexi Multiradio base station family,the Flexi Direct solution maintains the same high quality voice capability.

Seamless migration to LTE

Flexi Direct uses LTE network architecture (Flexi Direct has even beenreferred to as pre-LTE). This similarity effectively smoothes networkevolution to LTE and protects operators’ existing 3G network investments,potentially enabling earlier and simplified entry into the LTE market.

Since introducing the first 3GPP-standardized commercial implementation of

3G flat architecture, Nokia Siemens Networks has continued to invest indeveloping the technology’s capabilities. Flexi Direct introduces furtherenhancements to the already impressive throughput; it boasts downlink datarates of up to 100 Mbps and 34 Mbps in the uplink. Additionally it supportshybrid transport capabilities and IPSec for complete confidence. These are just some of the latest developments that demonstrate Nokia SiemensNetworks’ commitment to delivering a forward thinking solution, today.

Nokia Siemens Networks Flexi Direct is the only fully 3GPP compliant flatarchitecture solution for 3G networks. Only Flexi Direct allows operators todeploy 3G mobile broadband services using LTE-ready network architectureand equipment.
