The Design And Implementation Of SoftSwitch Apparatus Based On Next Generation Network

In the past several years, the telecommunication industry that once developed at full speed was losing brilliance gradually. Though telecommunication service increase still, acceleration rate has dropped already and ARPU (Average Revenue per Unit) value presents the downward day by day. An important reason for this kind of situation is that it lacks of new business and new applications, which are suitable for people's needs and can stimulate the development of telecommunication industry. Though intellectual network technology offers value-added services such as called-pay (800 business), credit card services that bring abundant profits to the operator, it has inherent defects of un-opening business development and running, SCP centralized control, bearing the weight of network tie, low ability of business customized at the same time, which have already hindered the further development of the value-added telecom services seriously and become a great perplexing problem of the telecommunication operator. Comparing to this, in communication of speech, the network communication based on IP has incredible growth rate, and has reduced the cost that launch the speech business. Meanwhile, the data business in IP network is developed rapidly. Its growth uptrend has already far exceeded the growth of the speech business. PSTN traditional pronunciation network based on TDM will merge with packet switching data network, forming the future generation network that can offer integrated businesses such as transmitting pronunciation and data. But for various reasons, the ripe Softswitch network is not general in business application. It is necessary probes into transiting to the Softswitch network smoothly at the existing telecommunication network platform.This paper has put forward the software system structure of a kind of common Softswitch network. This structure has realized the main part's software in the Softswitch network—Softswitch apparatus. Enterprises can form a Softswitch experiment network adopting our Softswitch apparatus and equipping with a little essential hardwires. They can probe into the cost and income at constructing real Softswitch network in the future from it. Then it can lay a good foundation to the Softswitch network for commerce.To different agreement standards, for making Softswitch apparatus reach easily...
