★Isolated with signaling Media Proxy Devices To ensure the security of the softswitch network, you can divide the security areas of the softswitch network according to the security requirements of the devices in the softswitch network and the security areas of the softswitch network, it is divided into two security zon

I. Introduction With the rapid development of computer and communication technologies, it has become the development direction of networks to carry voice, data, images and other services through public branch networks. With this trend of business-driven and network convergence, the next-generation network (NGN) with Softswitch devices as its core emerged. NGN is implemented in the group network. It adopts a distributed network structure to effectively

switch and an IP address phone and an NGN ﹖ 1. Origin of Softswitch The term "Soft Switch" can be said to have been translated from foreign countries. Its concept is basically formed with the development of the functional hierarchy of the IP telephone technology system and the concept of control separation. As we all know, in the traditional PSTN switching network, business control, call control, and transmission load are all concentrated in switches

service is currently the most important telecom service, operators cannot give up on it at once. At present, the maturity of softswitch applications in backbone networks is beyond doubt. However, after the introduction of backbone networks, due to the complexity of the end bureaus, business development also encountered difficulties. To solve this problem, operators tend to adopt the overlapping network development strategy. In the initial stage, the

1. IntroductionThe evolution of network architecture and broadband technology have promoted and accelerated the evolution of traditional networks to the next generation network NGN. With the expansion of the network scale and the gradual expansion of applications, especially emerging businesses with real-time requirements, such as VoIP, video conferencing, multimedia remote teaching, and on-demand video streaming, communication networks are more and more required to provide efficient end-to-end

The use of routers and switches is indispensable in network construction. In some vswitches, we use them in combination with the H.323 protocol. Today, we will introduce you to the basic knowledge of Softswitch technology and H.323 protocol. There are two strategies in the network architecture of the Next Generation Network: Smart endpoints and edges, simple network facilities; simple endpoints and edges; SMART network facilities. For the former, beca

applications. Only POTS users can access the NGN user access technical network through AG or IAD. AG or IAD interacts with Softswitch through MGCP/H.248 protocol to realize the Call Control of users through SoftSwitch, at the same time, AG or IAD implements speech codec, media stream packaging and compression, mute detection, and basic Sound Receiving number and other media gateway functions to enable medi

Starting from the R4 phase, NGN and 3G technology begin to come together: the soft switching mechanism of NGN load and control separation, the unified IP/ATM Packet service bearer are introduced into the 3G core network. The similarities and differences between WCDMAR4 Network and NGN network can be compared with the overall network architecture, basic transmission network, equipment network element function, Commercial/operational key technology and so on.

At the same time, this also makes the practice and goal of the Next Generation Network appear blind and confused for technology. Logical conflicts in some basic concepts have caused many people to be still confused about the relationship between the soft switch technology, IP phone technology and the Next Gener

After more than 10 years of hard work, China has built the world's largest public telephone network (PSTN), and based on circuit switching technology is always the most important equipment in the network, but also China's telecommunications equipment manufacturers Rapid take-off of the breakthrough. However, when the mobile phone users in our country more than the fixed telephone users this year, the traditional circuit switches are also beginning to face more tests, on the one hand, the develop

1 Soft Switch Technology introduction The SoftSwitch technology adopts the layered network architecture, separates the call control function of traditional circuit switch from the media gateway, and realizes the call control function, such as connection control, call process selection and call routing, through software. The SoftSwitch, on the one hand, created the network fusion, on the other hand,

Definition of soft switching With the development of computer and communication technology, the image has been recognized by more and more operators and equipment manufacturers by carrying voice and data in a public packet network. Under the trend of business driving and network integration, NGN Next Generation network model is born, and the distributed network structure is adopted in packet network to effectively carry voice, data and multimedia services.As the core technology of NGN Network,

network. Not only does the next-generation network require business practices that integrate the three technologies, including soft switch technology, H.323 technology, and SIP technology, many other problems related to the Operation Management of the Next Generation Network also need to be verified through the operation implementation of the IP telephone network. Therefore, domestic telecom operators should first build an IP telephone network with a distributed structure according to business

the evolution towards the next generation network goal. The term "Softswitch is the core of the Next Generation Network" is to be elaborated and discussed. Currently, another popular term in the next generation network discussion is "Softswitch is the core of the Next Generation Network ". I think it is worth further consideration. To sum up, the soft switch technology is one of the most important and crit

As the first civil airport in Shanghai and one of the three major international airports in mainland China, Shanghai Hongqiao airport has a passenger throughput of up to 30 million passengers per year. However, behind the busy and brilliant work of Hongqiao airport, A program-controlled switching network has been in use for nearly 15 years, and the devices running on the network are close to replacement and elimination periods. The overwhelmed switching network is urgently upgraded under the dri

network, so it is necessary to solve the problem of intercommunication address resolution and route selection. On the one hand, NGN is not a simple extension and superposition of the existing telecommunication network and IP network, nor is it a single node technology or network technology, but a change in the overall network architecture. What is needed is an overall solution. On the other hand, the emergence and development of NGN are not a revolution, but an evolution, that is, a smooth tran
