5. Network Landscape
Phase 1: Coexistence of all networks ( the coming ten years)
PSTN/NGN/3G coexist;
Multi-network service convergence to provide integrated access under “one number” ;
From the subscriber’s point of view, services are offered by an integrated multi service network.
Phase 2: Integrated multi-service network (ultimate network)
The ultimate goal of NGN: Deliver combined voice, data, video, and 3G over a single network.
—— Report on Annual NGN Summit 2004
There is no doubt that NGN would be the ultimate telecom network.
But The major part of telecom revenue will still come from voice service in the coming 5-10 years.
But the migration to NGN should be a step-wise process. That is, it is a long term and gradual process but not a impetuous revolution. According to the report on Annual NGN Summit 2004, the development of telecom network should be divided into 2 phases. In the first phase, that is in the coming ten years, all the networks, including PSTN/NGN/3G will coexist.

6. Baffles of convergent service deployment

PSTN is the short board !
For the service layer, we need to provide convergent service. But compared with NGN and 3G, PSTN is the short board.
Lack of centralized subscriber database
Lack of centralized service control node
Big difference on structure of PSTN/NGN/3G

Switchover time is configurable and also adjustable according to network status.
Total service switchover time is less than 5 minutes.
Mutual-help is supported between various Softx. Each MG can connect to multiple Softx. MG’s traffic of the failed Softx can be distributed to multiple Softx, reducing the traffic load of the backup Softx under the situation of disaster.
Automatic Switching Mode: Lost of heartbeat signal is the precondition . If the heartbeat is detected normally, the registration request of media gateway will be denied by Secondary SoftX.
Manual Switching Mode: NGN components can be controlled via NMS to various switchover and restoration. SG

Service switching center
PSTN Transit Layer
TS construction with NGN：All traffic of LS (including intra-office traffic) are transported to the TS, making NGN TS a S&S center of the whole network.
S&S CENTER：Screen the difference of LS, releasing fast delivery of service across the whole network, without upgrading of each LS.
CENTRALIZED SUB DATABASE(SHLR)：Centralize the sub attributes, realizing the separation of sub service attributes from the LS.
Select trial sites to build a SSC at the transit layer using NGN: All calls of LSs are processed at the transit layer, making it the service switching center.
Powerful service switching center: hides the features of LSs to enable fast delivery of intelligent services network-wide.
Centralized subscriber database (SHLR): isolates service features from LSs to implement mass deployment of subscription services.

全网业务实现的要点：
（1）在汇接局层面，建立交换业务中心（2套Soft3000+UMG8900），将承担网内所有交换端局送来的呼叫，并根据呼叫要求，在全网用户数据库（SHLR），SCP的配合下触发智能业务；
（2）各个端局（包括模拟交换机和老式数字交换机）的硬件不作改造；分步骤将所有端局之间的中继电路和路由取消，所有端局只和交换业务中心建立中继电路，所有路由均指向交换业务中心；每一个呼叫，包括局间呼叫和内部呼叫均要先上到交换业务中心，然后由交换业务中心进行交换，并根据呼叫的要求触发相应智能业务；
（3）建成后，由于所有呼叫均上交换业务中心，对端局交换机的要求大大降低，延长了老交换机的使用寿命；网络变为典型的两级交换网络，优化了网络结构；最重要的是网络中不再存在数字化孤岛和业务孤岛，各种业务可以在全网实现；
Construct SSC, making the analog switches and old-fashioned digital switches the access equipments whose calls and services are sent to SSC to realize switching and service trigger. Achieve network-wide coverage of digital switching and diversified services without modifying the end offices
Achieve network-wide coverage of digital switching
and diversified services without upgrading the end offices

15. Benefits
Cost savings: both problems of intelligent PSTN and provisioning of NGN services are addressed;
Service experience: implement network-wide service provisioning without investing in existing LSs;
Local CDR: local CDRs are provided by the transit offices. There is no need to upgrade or reconstruct LSs;
Optimized network structure: target structure reducing overall network cost and handling the problem of large numbers of small LSs;
Simplified maintenance and routing of LSs: consequent human power savings, reduced requirement for LS maintenance technicians, and better support for centralized maintenance.
投资节省：使用NGN建设，在解决PSTN网络智能化的同时，又能够面向未来，随需发展NGN用户和业务，相当于一个投资两份回报；
业务体验：现网老端局不需任何投资，即可全网开放业务；
市话详单：通过汇接局出全网市话详单，无需端局升级、改造和大量联机采集费用，方便低成本实现联机实时计费；
网络结构优化：符合目标结构，降低网络综合成本，解决大量小端局问题；
维护体制简化：端局的路由和维护大大简化，节省大量的维护人力，降低端局维护人员要求，更好地支持集中维护。
Leave all the old local switches unchanged. Enhance the capability of PSTN. Future-oriented solution since it employs the NGN architecture. At the beginning you can deliver some NGN service to give more experience to the PSTN user. In the future you can develop new NGN subscriber. So we can see it’s a solution of one investment, two returns.
All the services can be deployed without any change or upgrading or investment to the current legacy local offices. without any change or upgrading or online sampling cost for each local office, you can get Local CDR network-wide. Realizing the real-time charging cost-effectively；
It complies with the target NFN structure. So it can decrease the network integrated cost, solving the problem of a large number of small local offices.
The routs and maintenance of the discrete local offices are considerably simplified, saving a large number of maintenance staff, decreasing the demand for the LO maintenance staff, realizing a better centralized maintenance.

华为在NGN领域的持续投入也带来了丰硕回报：
截至2003年7月中旬,华为NGN解决方案已经在中国国内所有运营商及大量海外运营商取得规模应用。
2003年5月，中国电信集团公司正式下发“关于与华为公司联合进行NGN集团客户解决方案试验的通知”，此次试验容量13000用户，覆盖深圳和杭州两地，整个试验纳入中国电信已经组织开展的NGN业务试验统一管理。此举标志着华为正式进入中国电信NGN试验并超越其他实验厂家, 成为中国电信规模最大、用户数量最多、开展业务最丰富的实际案例，目前该局已经开通并投入实际运营；同时作为NGN领域最重要的合作伙伴之一，华为公司将与中国电信一起，就NGN的商业组网模式\运营模式\维护管理模式等展开一系列深入的研究。
2003年上半年，在中国网通集团总部NGN选型中，华为公司表现出色，处于第一集团；随后拿下了网通今年招标各省的所有项目，正式进入包括西南、西北、广东、四川、云南、黑龙江等6个省的NGN项目，目前，已经全部开通，西南、西北等地已投入实际运营。
2003年5月，华为公司完成卫通NGN项目三期合同，网络覆盖150个城市，是目前中国乃至世界上覆盖最广的NGN网络。
同时，在海外华为公司也取得巨大进展，中标了文莱的全国固定网络(全网14万线，为目前亚洲用户规模最大的NGN商用网络)，同时产品进入了英国BT、香港PCCW、香港和记、新加坡电信、马来电信、巴西Telemar等10余个国家。
