The NASS is responsible for managing the users attached to the access network in terms of user authentication, allocation of the IP address, and location management. In NGN R1, Telecommunications and Internet Converged Services and Protocols for Advanced Networking (TISPAN) studied the internal architecture and external interface protocols of NASS and published the relevant technical specifications. In NGN R2, TISPAN focuses on the study of mobility and nomadism as well as the ability to support various access network architectures. There still remain several issues that need further study.展开更多

Following the entrance of China into the WTO,the position of “green barrier ” becomes significantly important in the trade of textile products. As China is a big country of textile production,speeding up the research on standards for products of ecological textile,countering the latest situation appearing in international trade of textile,to take as quickly as possible responsive measures is a very urgent problem in breaking through the foreign technical trade barrier and promoting the development of foreign trade.展开更多
