The telecom sector hinders China's Softswitch Development

The telecom sector hinders China's development of softswitch, and technical factors and policies restrict the development of SoftSwitch. These problems will be solved sooner or later, I believe that the related technologies and strategies will be gradually improved in the development process.

Users of China Mobile China Telecom China Netcom's service quality can hinder the development of softswitch in China. It is not only reflected in the technical level, but also in the control level. The Next Generation Network of NGN is still in the standardization stage in China. As one of the technologies with Chinese characteristics, Softswitch has mature and stable related standards and products, and has been applied in telecom-grade networks. The development trend and resistance of softswitch have received much attention.

The deployment of softswitch by operators is blocked

The Application and Implementation of NGN in China are mainly reflected in the softswitch layer. China Mobile and China Telecom have introduced the development of softswitch at the long distance level. In order to achieve network intelligence, China Telecom and China Netcom have established the use of softswitch to replace the board as one of the solutions, in addition, China Telecom has launched the SHLR (SmartHLR) proposed by SoftSwitch and network intelligence in Guangzhou, which mainly stores information on signing value-added services for users.

And the ing between physical numbers and logical numbers. At the same time, these operators are also conducting experiments on R4, so that after obtaining a 3G license, you can consider using R4 to build a 3G network. From the above trends, we can see that both fixed SoftSwitch and mobile Softswitch will have a great development in China.

Resistance source

There are technical and policy factors that impede the development of softswitch in China. In terms of technology, the difficulty lies mainly in the service quality of the access layer. Because of the diverse access types and methods, these access methods are mainly used to provide users with online services, most of the devices do not take into account the provision of voice services, the isolation of voice services from data services, and the positioning and recognition technologies of users.

In addition, these problems involve complex technologies and configuration management issues, some of which are not yet mature. The key factor hindering the development of softswitch in China is not only at the technical level, but also at the control level. The main factors that affect the implementation of corresponding control policies are as follows:

◆ The Control Strategy for the Development of NGN or Softswitch is a difficult challenge in the industry. Different countries have different control ideas. However, it is still difficult to reach an agreement on what control ideas are suitable for China.

◆ Softswitch users can access the softswitch network through the Internet, but the Internet currently does not provide service quality assurance. Therefore, it is difficult for these users to guarantee the service quality only through the development of SoftSwitch, in this case, how to control is also a problem that puzzles people in the industry.

◆ China's PSTN network has strong service capabilities. If the control on NGN and Softswitch is released, it is difficult to determine the impact on the existing PSTN. These control problems constitute a major factor hindering the development of NGN and SoftSwitch. However, the development and application of softswitch have become an irreversible trend and these problems will be resolved sooner or later, related Technologies and strategies will be gradually improved in the development process.
