1. Preface The Next Generation Network (NGN) is an integrated and open network architecture which can provide a variety of services including voice, data and multimedia, and SoftSwitch is the core of the next generation network call and control, which provides real-time demand and service call control and connection control function for next Generation network (NGN). Since 2000, there have been some operators in the test or use

R4 and R5 phases correspond to the two routes of network exchange and development. In this paper, the correlation analysis of SoftSwitch in R4 stage is limited. 1, Soft exchange Compared with traditional networks, the benefits of SoftSwitch are well known: Open Open system, so that operators are free to choose to design their own network, easy to improve competitiveness, so that the cost of integrated

In daily practice, the core of the soft switch technology is to explain its principles, this limits that the next generation network can only be a "no-network" mode in which soft switches are connected to each other ". Obviously, the "no-network" next-generation network architecture can only support one or several soft switches, which is not suitable for telecom operators to operate on a large scale. This phenomenon is called the "island phenomenon" of the soft switch technology practice ". On t

Session Border controller (SBC) is a standard configuration product for NGN and IMS networks.SBC is generally located between two service provider networks in a peer environment, or between an access network and a backbone network that provides services to residents and enterprise users. Although some SBC only process signaling, most of them process both signaling and media. This type of SBC implements communication be

a call,Lost calls do not include busy users, unresponsive users, and out of service areas; Build latency:The latency returned by the user to initiate a call to the called user response or system response to the signal; Release latency: the latency when the user actively ends the call to the system to complete resource release; Latency includes system processing latency and network transmission latency; Information Production Department General Technical Requirements for

choice in the initial stage of Gepon application, when the number of voice users is not much, especially the SoftSwitch network has not been able to cover. It has the characteristics of simple network structure, convenient implementation and low cost, and can carry out voice service quickly on Gepon network. The second mode of access is VoIP voice solution based on SoftSwitch network. It makes full use of

with the billing system, access to the time period of the limited user distance from the end of the hour, to the end of the time can actively force users offline Through the bandwidth control function based on the user, the system is completed by the monthly bandwidth fee. Support for non-certified business There will be some business in operation network, such as: VoIP Access Service, enterprise users in the complex building, etc., the VLAN ID can be used as the identity of access control, a

' ability to access, and provides integrated intelligent Network service for IP network users or PSTN, GSM and CDMA users. For an integrated intelligent network, SoftSwitch and the access point it controls form a virtual SSP, via Inap (which can take INAP/TCAP/SCCP over M3ua or inap/tcap over Scua) or SIP protocol via signaling gateways, and integrated intelligent Network ISCP Interoperability, the common provision of intelligent network services.

Video services include a variety of business types, such as IPTV and CATV. For IPTV business, the communication FTTH system has no bottleneck structur

transmission for multiple businesses has become the norm, and the core layer applications for education and other industries also fully show this demand trend: multimedia Applications such as VOD and electronic reading room have become common projects for campus network construction. Integrating the four main functions of teaching, scientific research, life and office is the general trend of campus network development, the construction of an operational network with the functions of network man

sigtran. This project started in 1996 and implemented the No. 7 signaling system recommended in the ituq.700 series. With the rise of VoIP and SoftSwitch, openss7 focuses on the implementation of sigtran protocol (sigtran can be considered as the NGN version of SS7 ). In fact, openss7 is not limited to the 7th signaling, but a series of ISDN and SoftSwitch signaling are all under consideration. For techni

Internet. However, it is recommended to use the fixed-point algorithm, which is very inefficient at floating-point algorithms. From the usage perspective, rfc283 is generally used, that is, out band. Generally, Softswitch servers support these methods. The asterisk I know supports the SIP info, RFC 2833, and inband methods, however, rfc2833 has the best compatibility. Because IMS uses RFC 47233 to replace rfc2833 for dtfm, there may be compatibility
