1 Insight of NGN Deployment HUAWEI TECHNOLOGIES Co., Ltd.
2 Content NGN Network Transformation NGN Network Migration Evolution From PSTN to IMS Case Studies Brunei Telbru: World First Commercial NGN Deployment Singapore SingTel: From C5 Consolidation to ALL IP Summary
3 Drivers for Network Transformation 1 Market Strong competition Obsolescene of TDM technology. Technology shift from circuitswitch to packet-switch. Emerging access technologies Open standard and architecture. 4 Technology Convergence Decline in fixed line subscriber. Drivers Convergence in services Convergence in access network Convergence in Fixed and Mobile. Convergence in telecommunication and computing. 3 Competency Limited growth in PSTN High OPEX Long time to market Lack of service portfolio 2
4 What is the Outcome? NGN Network Model New Service Opportunity Service & Application New Network Architecture Open Protocols e.g. Parlay, OSA, JAIN Call Control Transport Open Protocols e.g.. SIP, MGCP, H.248 Access NGOSS - NMS - Billing - CRM New Business Competency New Network Flexibility New Transport Efficiency New Network Operation New Organization Structure

22 Summary Can We Ignore NGN? Market POTS is still the primary revenue generator. The most lucrative users still remain in POTS. POTS is still popular because it is widely available and affordable. Network Platform NGN is a reliable and stable platform for network transformation. It has passed through 5 years of simulation, testing, trial and upgrade. Differentiated Services Flexible platform to create and provision a broad array of VAS. Various exciting NGN applications are ready to market.
23 Summary Can We Ignore NGN? Business Planning The risk of migration has been thoroughly assessed and minimized. NGN network transformation is supported by successful commercial business case from established telecoms. NGN migration guarantee smooth service continuity and the subscriber data profile can be fully retained. Competency Reduce the CAPEX and OPEX of the network. 100% inherit the traditional PSTN s basic and supplementary services. Innovative voice and non-voice services ensure higher quality of experience NGN is the most appropriate choice to resolve difficulties currently confronted by operators. Network operator s investment in NGN will be protected in IMS smoothly.
