  7. Relationships Among NGN, Softswitch and IMS - ztecommunications.

It can also provide C5 services by connecting different terminals to core service networks via data access. There are two structures to construct Softswitch networks. One is temporarily named as integrated Softswitch which accesses different wireline users, including narrowband and broadband users. The other consists of narrowband and broadband Softswitch, where Media Gateway Controller MGC and SIP server, which are responsible for the access and control of narrowband and broadband users respectively, are cooperatively used for Softswitch services.

Softswitch is a preliminary stage of the NGN and it aims to the services related to wireline users. However, its development should provide room for future requirements of NGN. Therefore, the narrowband Softswitch can be deployed to meet the demands of the market. It is recommended that integrated Softswitch, rather than broadband Softswitch, should be used for the network construction, although there are requirements for broadband services.

It seems that broadband Softswitch supports mobility of these terminals and meets some requirements of IP voice, and the SIP server can evolve into IMS according to its standards. However, there is a big gap between the Softswitch and IMS. Specifically, the broadband Softswitch has no centralized database setting and management, and processing the user and service data via the local server.

The core structure, network element functions, interfaces, and procedures are defined in R5. Presently the R5 and R6 are on hold.

It can support fixed access. After the 3G licenses have been granted, each operator has the possibility to be a full-service operator. A traditional fixed network operator soon will probably build an IMS network under the market competition, even if he has established a R4 3G network with services. At the beginning, this IMS network can only accommodate 3G users, but its network protocols should consider the access of wireline broadband data users. In nature, it is better to plan the two user access requirements as a whole, and construct a convergence network at the very beginning.

However, there are differences in service time and service type between wireline and wireless user accesses, which possibly makes the service networks apart. The IMS is also a generalized service platform for future multimedia applications, such as presence, message, conference, Push-to-talk over Cellular PoC , and other typical services.

The All-IP Transition Problem

As to traditional mobile network operators, requirements for IMS are actually stimulated by the need of future FMC and current market. Consequently, not only the requirements of mobile users, but also the requirements of VIPs and potential fixed broadband users are worth to consider at the IMS network planning. More Information?

Performance Optimization of Digital Communications Systems. Vladimir Mitlin. Consisting of ten chapters, this monograph presents a unique method for determining the quality of a communications channel - a great advantage to any company that uses this method. The book presents a method for the transmission of proprietary data.

It also describes the means to reduce the peak-to-average power ratio and introduces optimal phase shifters for multicarrier communication systems. This volume contains numerous illustrations and includes appendices that offer optimization puzzles, MATLAB scripts, and some newly discovered properties of flat-spectrum and spectrum-shaped waveforms. Abhishek Roy. Recent advancement and increased growth in Web technologies have resulted in an even greater need for more efficient scheduling and data transmission strategies.

An increased reliance on wireless communications devices, with their constraint issues, has further complicated the problem. While both push and pull strategies provide certain solutions, each has limitations that compromise performance.

What is becoming clear is that any optimal solutions will require novel push-pull hybrid approaches. Chaotic Signals in Digital Communications. Marcio Eisencraft. Chaotic Signals in Digital Communications combines fundamental background knowledge with state-of-the-art methods for using chaotic signals and systems in digital communications. The book builds a bridge between theoretical works and practical implementation to help researchers attain consistent performance in realistic environments.

It shows the possible shortcomings of the chaos-based communication systems proposed in the literature, particularly when they are subjected to non-ideal conditions. It also presents a toolbox of techniques for researchers working to actually implement such systems.

https://ticnecictai.ga A Combination of Tutorials and In-Depth, Cutting-Edge Research Featuring contributions by active leading researchers, the book begins with an introduction to communication theory, dynamical systems, and chaotic communications suitable for those new to the field. A Toolbox of Techniques—Including New Ways to Tackle Channel Imperfections The book covers typical chaos communication methods, namely chaotic masking, chaotic modulation, chaotic shift key, and symbolic message bearing, as well as bidirectional communication and secure communication.
