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 t

media gateways, which are controlled by the Call Server and MSC Server respectively. Because two virtual media gateways share hardware and software resources, resource management and control become more complex. Therefore, the integration of fixed network and mobile network in narrowband Softswitch is difficult. In broadband Softswitch, the functions of the fixe

architecture? In the fuzzy definition of NGN, some people think that Softswitch is NGN, while others think that the traditional PSTN voice service supported by Softswitch is the whole of NGN. Yin Kang, chief technical consultant of Cisco Systems Asia Pacific NGN/VoIP, believes that the vague concept of softswitch reflects the industry's misunderstanding of

accordingly. For example, multiple network segments are supported, multiple isolated physical ports can be provided or multiple VLANs can be supported on one physical port. Media ports can be dynamically opened and closed, and port settings can be minimized; user-oriented services can be faced with users through Web or Portal, so as to reduce risks by means of business proxy; devices need specialized software/hardware platform design. Resolution of Q

In recent years, SoftSwitch technology has become the focus of public attention, it will become the core technology of the next Generation network, the information industry after a turn to put forward to the next generation of IP Fusion network SoftSwitch technology, is currently active in 3G core network technology research, the ultimate goal is to have the integration of multimedia business capabilities o

, when the message sent from the same source IP address and port exceeds this value within one minute, the address/port is blacklisted and corresponding measures are taken, the ability to shield the address of the Communication peer based on business needs, user security needs, and operational needs. To work with secure Softswitch networks, each device needs to be improved accordingly. For example, multiple network segments are supported, multiple iso

to users who use telephone services and data services on computers at the same time. In this case, a dedicated "softphone software" needs to be installed on users' computer devices ". Media Servers Access Gateway (MNS) is used to complete information about various multimedia data sources and adapt Multimedia Streams mixed with video and audio to IP packets. H.323 Gateway: used to connect an IP address Telephone Network Gateway using the H.323 protoco

on the access, the activation process of the local Softswitch is very different from that of the PSTN. The activation process includes activation of the system, network, and terminal devices, and the process will be more complex. A local softswitch system may cover the entire local network or even multiple local networks. This function replaces multiple local ports of the PSTN. This makes the billing syste

The Softswitch technology will become one of the core technologies of the Next Generation Network. This is a consensus. Here we will mainly introduce the ten common functions of the Softswitch technology. With the increasing development of the telecom market and the Development of the Next Generation Network (NGN) as the key role of Softswitch technology, it is i

services over the Internet, you must ensure the communication security between the service access device and the softswitch network. Security requirements for security domains of Internet access networks include: L2TP, IPSec, and other tunneling technologies must be applied between terminal devices such as SIP phones and software phones and Internet and softswitch
