For NGN technology, it is not sent. I have just started to NGN technology, so there are a lot of questions I want to ask everyone, I have a few aspects of design:
1NGN must be an open architecture, a closed network architecture that makes many people difficult to start, master the relevant knowledge, this can learn from the development model of Internet.
2NGN must be a business to drive, the business that is currently closed network development is far from satisfying the needs of the people, from the operators of each network, when there is a new business to be launched, it is possible to earn To a large number of Money. In this regard, everyone has made a lot of efforts, and the open API is one of them, including: Parlay specification, Jain specification.
It's not enough for 3 times. Let's talk about it next time, please I want to discuss, soft exchange technology, SIP, and VoIP technology next time. Goodbye
