System introduced with the typical meaning of intelligent communication network construction projects in Guangzhou the need for specific project components and implementation.
IP technology with a large number of applications and getting more mature, its used in voice networks, data networks and the advantages of the network becomes more and more video, IP technology, flexible application of the traditional networks richer, personalized, diversified business with solid protection. The traditional fixed-line operators, IP-based NGN technology and based on Mobile The Home Location Register (HLR) the combination of third-generation intelligent network (fixed 3G) are mature.
In China Telecommunications Market Competition Increasingly competitive environment, the diversified and personalized services will be the major difference operators compete for market attention. Therefore, using NGN and other next-generation technologies to upgrade the voice network, the network is more open, flexible, rapid response and other characteristics, to meet the needs of market competition, the traditional fixed-line operators, more pressing and important.
China Telecom Group since 2003 on the “network intelligent” in-depth research, through continuous exploration, that the intelligent network is technically mature, should be combined with the actual situation of each local network to actively promote the use of . The following brief introduction to Guangzhou, intelligent building of telecommunications networks.
Guangzhou Telecom local network to today has been one of the national large local network, is a long-distance level, aggregation layer, end offices layer of three levels, a tandem network. Guangzhou, the local telephone network after years of construction, network size, network capacity across the whole country is leading. As of the end of 2004, total fixed telephone network Switch Installed capacity of more than 5 million, PHS installed capacity has more than 1 million, the local telephone network covers the city of Guangzhou 10 District 2 county-level city. Guangzhou Telecom in August 2005 began to transform the network intelligence, using a well-known domestic manufacturers of communications equipment NGN products to existing fixed telephone network of the tandem layer transformation, in the first quarter of 2006 is expected to allow phone users can enjoy the NGN new business and services.
With the continuous expansion of network scale and the increased demand for network intelligence, Guangzhou Telecom timely introduction of NGN technology to solve the following five questions to the operation of competition in the future, sustained a leading position.
1, Network PSTN Network Optimization PSTN experienced a long period of operation, the voice service revenue in the whole the dominant position, but because of model complexity, and aging equipment has been unable to meet the growing needs of the user’s personalized service, so Implementation of PSTN, intelligent and mobile, which is adapted to the new competition in the marketplace demands.
2, integration of PHS / urban telephone communication network and the PSTN and other networks
PHS network and the PSTN in the businesses have their own intelligence network, billing management platform, business and launched the difficulties are great; users to share resources are not sufficient. In order to give full play to advantages of PSTN and PHS digging and packaging business to gain more customers and increase operational efficiency, we need to have the PSTN and the PHS network integration.
3, timely introduction of Softswitch NGN technologies has become a recognized goal of network evolution by China Telecom for many years Test And test business, technology and equipment that have been mature, the agreement has been basically perfect, the next period of time the traditional carriers will gradually smooth transition from existing PSTN to NGN. NGN’s greatest strength lies in their strengths as well as network integration with network construction operation and maintenance cost reduction advantages. NGN technology with the business operator to provide enhanced capabilities to improve competitiveness. Business network from a single multi-service network integration into the network, can greater reduce the network construction, operation and maintenance costs; and Internet combination to provide more flexibility on Web, multimedia services to customers services; and, NGN service platform to provide a strong customer demand for business easier, the third party can be based on a unified business platform for business development, customer service can be customized based on Web pages. All this gives our customers new, more personalized business environment in which Next Generation Network Business services with unparalleled advantages.
4, broadband communication networks, multimedia With the rapid promotion of broadband network bandwidth, QoS and security technology continues to improve, the broadband network to provide voice, data, video, multimedia business as a whole has become a communications network development.
Telecom operators in order to more fully utilize existing network resources, rich Internet applications, and better serve our customers, they are bound to multi-media business operations as the focus of attention. The market demand for multimedia services only from the early use of video conferencing to today, including video conferencing, two visual communications, and voice terminal interoperability, collaboration and other visual multimedia applications office, a simple video conferencing services have been far from satisfying the needs of users, multimedia services are no longer just a video conference. Diversity, intelligence, collaboration has become the multimedia services of all operators is the key competitive. What kind of network platform used to provide any kind of application, the business is operating is convenient and practical and convenient as operators need to focus on problems.
5, the traditional network and integration of mobile 3G
NGN and mobile operators increasingly concerned about 3G. Traditional carriers have many years of business PSTN, broadband experience, with a considerable number of PSTN and broadband resources. They must consider: how to use existing resources to building and development of mobile 3G mobile 3G network services and users? How are network evolution to NGN and NGN and future 3G networks and mobile convergence? How fixed “enjoy” NGN and mobile 3G business platform? fixed user how to achieve “seamless” transfer network to the NGN and mobile 3G network? mobile 3G network early how to make use of existing fixed-line network edge, improve service quality?
Intelligence in the Guangzhou Telecom NGN Softswitch solution, the reference mobile network user data property management, the introduction of a centralized database SHLR. SHLR initially stored in the user’s physical and logical number of the corresponding number of relations and properties of the user’s smart business to realize the whole network to distribute telephone numbers and intelligent mix of business trigger; follow-up of all the circumstances can be used
