Summarize the concepts and definitions of Softswitch technology applications

The Application of Softswitch technology is summarized from concepts to definitions. Since the Chinese news launched by Google, many industries on the Internet have been greatly affected, the Application of Softswitch technology will also be affected. 2010 is a year of many things on the Chinese Internet.

Softswitch Technology and Its Application

With the rapid development of communication network technology, people's requirements for broadband and business are also growing rapidly. In order to provide users with more flexible and diverse existing businesses and new businesses, providing more personalized services to users, and proposing the concept of next-generation networks. At present, major telecom operators have begun to experiment with next-generation communication networks.

The Application of Softswitch technology is one of the focuses of next-generation communication network solutions. The application of Softswitch technology has become a hot topic in recent years. China's network and exchange standards research group has completed the overall technical requirements framework for the softswitch system, and plan 863 has also set up research projects for the softswitch system in multimedia and mobile communication systems.

Proposal and definition of Softswitch

The concept of softswitch originated first in the United States. At that time, in the enterprise network environment, users used Ethernet-based phones to implement the PBX function through a set of Call Control Software (CallManager and CallServer) based on PC servers ).

For such a set of equipment, the system does not need to separately lay the network, but can achieve unified management and maintenance only through sharing with the LAN, the overall cost is much lower than the traditional PBX. Because the enterprise network environment does not have high requirements on device reliability, billing, and management, it is mainly used to meet communication requirements and has a low device threshold. Many equipment vendors can provide such solutions, therefore, the IPPBX application has achieved great success.

Inspired by the success of IPPBX, in order to improve the comprehensive operation efficiency of the Softswitch technology application network, the network development tends to be more reasonable and open, and better serve users. The industry has put forward the idea that the traditional switching device components are divided into call control and Media Processing, and standard protocols MGCP and H248 are used between the two, as a result, SoftSwitch technology came into being.

The concept of softswitch was quickly recognized and valued by the industry. The establishment of iscinternationalsoftswitchconsor.pdf further accelerates the pace of development of Softswitch technology applications, the standards and protocols related to Softswitch have received the attention of IETF, ITU-T and other international standardization organizations.

According to the definition of isc in the international Softswitch Forum, Softswitch is a device and system that uses program-controlled software to provide the call control function and separate media processing. Therefore, the basic meaning of Softswitch is to separate the call control function from the media gateway transport layer, and implement the basic call control function through software, thus realizing the separation of call transmission and call control, establish a separate plane for control, switching, and software programmable functions.

The Application of Softswitch technology mainly provides functions such as connection control, translation and routing, Gateway management, call control, bandwidth management, signaling, security, and call details. At the same time, Softswitch also encapsulates network resources and network capabilities, and connects to the application layer through standard open business interfaces, allowing you to quickly provide new services on the network.
