Shanghai Unicom will start the NGN Softswitch Service

NextGenerationNetwork (NGN) is a new concept used by the network to describe future telecommunication networks. It is like a big umbrella, covers the fixed network, Internet, mobile network, core network, man, access network, user resident network and many other fields. The evolution of technology has brought about the rapid development of network convergence, telecom business integration, and personalized communication services. As a core technology of NGN, Softswitch provides the possibility of separating the service network from the bearer network and integrating various service networks. IN our daily life, we have enjoyed the new pre-paid (VOICE) telecom business developed on the Intelligent Network (IN) platform by Ruyi 133 and Ruyi Tong. Today, NGN-based Softswitch can develop more media (Multimedia) than IN platforms) new Telecom businesses with more flexible technical implementation, wider user base, lower personal communication costs, and closer to personalized communication needs, it will bring about a major change in the communication technology and business market.

Shanghai Unicom officially launched the China Unicom NGN internal test project, marking an important step for Shanghai Unicom to explore the next generation network evolution. In addition to the completion of basic voice communication between the public internet and the voice exchange network, this test will also provide the following typical applications:

1. Interconnection Between NGN multimedia visual terminals and fixed vision, and activation of multi-party video call services　

This application is not only functionally compatible with the original VC private network, the biggest feature and business selling point is that it expanded the user base from the original limitation to the public Internet as long as it was connected to the public network through the data leased line access to provide the fixed vision service, users can enjoy all-new video communication services at home or anywhere.

2. Communication between mobile baoshi and NGN multimedia visual Terminals　

It fully reflects the core competitiveness of China Unicom as an "integrated telecom operator" to provide "Differentiated Services, integrates high-end users and group users of the CDMA 1X mobile PDA with NGN users for enterprises and individuals.

3. "No. 1" business, also known as personal communication assistant service　

Its design philosophy is mainly to communicate with individuals as the main body, with a number as the symbol of personal communication, you can set the relevance of your personal office phone number, home phone number, and voice mailbox through personalized self-service, such as pre-call service and voice mailbox settings, you can choose to enjoy the communication service based on your preferences and the best communication fee combination.

In addition to the preceding typical new services, as a platform that can be opened to third-party application service providers, NGN Softswitch uses the Parlay and SIP interfaces, it is a third party (similar to the ICP-Internet content provider and sms sp-business provider on the internet today) based on the softswitch platform, developing more value-added telecommunications services that are more flexible and more compliant with customer needs provides unlimited possibilities. As a result, the Softswitch Technology and Application Based on NGN will surely become a bright landscape in China's communication market in the future.
