Challenges for survival

� How to strengthen the subscriber base and customer loyalty

� How to increase ARPU by introducing attractive service packages for different customers

� How to cut down much more CAPEX & OPEX than competitors

� How to construct a powerful infrastructure to meet the uncertain services requirements in the future

� Reynolds, BT Senior Vice President, said, “Those carriers who are sitting there for opportunities is destined to be degraded into sellers of common commodities…For traditional carriers, the only way to survive is progress and reform.”

Operator’s challenges:

Transformation is the only way out

Transformation is the only way out

How to achieve transformation successfully?

� Target : To use unified infrastructure� Easily to deliver legacy and new services� Significantly to reduce CAPEX & OPEX

� Broadband stands for the future of fixed network carriers� Legacy services are still the main revenue source in quite

long time� The most difficult part is to choose a suitable access

layer solution � Different service interface, different access technologies� More than 60% investments on access network� More than 80% OPEX cost spent on this part

�� Scenario 1Scenario 1� Dated PSTN network with highest CAPEX & OPEX, operators plan to replace the

existing infrastructures by one multi services network to provide BB VAS while preserving all traditional services, like BT, KPN, BTC, …

�� Scenario 2Scenario 2� Advanced PSTN network, focused on developing BB network to provide BB

services Via DSLAM /FTTx, plan to consolidate multi network into single BB infrastructure based on all IP technologies, like FT, TI, Telefonica

� DSLAM becomes the central element for future voice offers for VoIP (use of ADSL). Will a place remain for service on analog lines ?

Summary& Understanding

The maturity of AN is one of the key factors as access network CAPEX occupies 70% of total.Only MSAN has been deployed commercially in large scale and IP DSLAM��TDM/VOIP mode is under researching.IP DSLAM+VOIP/VOBB could not been deployed in large scale without E2E QoS in the whole networkUnified multi-service network based on IP technologies is the common trend Revenue from legacy services should be seriously concernedRequirements of NG-AN solution

Legacy service migration abilities towards NGN, IMSFuture proved BB services availabilities Powerful OAM and services provision abilities Flexible adaption abilities
