The Hebei Softswitch Of Chinaunicom Construct

The NGN(Next Generation Network) is developing fast along with the development of telecom technology and the IP network. As the core technology of the NGN, Softswitch is being paid more and more attention. And as the NGN's module with control function, Softswitch provides real-time service provision,Call Control and connection control function. Softswitch is one of the core equipments of the network development and the NGN, which is isolated from transmission network. Soft switch's mainly function is to accomplish the call control, resources assignment, agreement management, router assignment, certification, and calculate expenses. And at the same time, Soft switch can also provides all of what existing CS switch can do to the users, and provides programmable ability to the third party. The NGN is a network of service-driven, which can rapidly and progressively to do new business through the separation of Service Call and Control and bearer。Traditional service providers can effectively protect the investment of PSTN and advance the operation value of PSTN by introducing NGN into PSTN. Chinaunicom of hebei has already established a comparatively complete Soft switch network through several years'effort. However, along with the reconstruction of the existing network and under the circumstance of the increasing number of switch and the demand of new business, the Soft switch network of Chinaunicom of hebei has lots of problems at the moment. The article mainly analyzes the actuality of the network of Chinaunicom of hebei and tries to bring forward the next ideas to make the Soft switch network of Chinaunicom of hebei more perfect through analyzing the existing deficiencies. Besides, the article is also trying to study how to upgrade the Soft switch network of Chinaunicom of hebei through the comparison of the project and the calculation of the data.
