| Now the telecommunications industry is growing faster than the astoundingbreakthrough and revolutionary technology has undergone fundamental changes in thecomposition of the network traffic. New technology and new demand-driven network tothe next generation of the development of the telecommunications industry in order toquickly adapt to these new needs and new technology changes, it should not need a newnext-generation network architecture with which to adapt.The first two chapters of this dissertation are mainly the mobile softswitchprospects, the basic concepts of network structure, and functions are introduced. Theintroduction of articles mainly from mobile softswitch application prospects. Includingcircuit areas and application of packet fields to expand, and also the brief introductionof the third generation mobile communication systems and intelligent networkapplications in the field. Second the Overview Introduction softswitch developmenttrend and Alcatel SpatialAtrium mobile softswitch. Chapter II explained from bothbroad and narrow concept of the softswitch. Broad softswitch is an abstract concept,generally refers to a wide range of broadband access networks. Softswitch application inthe narrow sense is completely different horizontal combination mode; release itstransmission, call control and service control interface, the formation of open softswitcharchitecture. Hen introduces the basic concepts of packet switching, packet switchingwas originally developed a exchange order to complete the data communication service.Ideological control in separation in the process of development of technology, thetelecommunications network, and gradually formed a softswitch concept, it has beenapplied in the fixed telephone network. The softswitch divided into the access layer,transport layer, the control layer and the business layer. Secondly, the development ofthe mobile communication network, the mobile communication system of the existingnetwork structures were introduced it, including a mobile terminal, a base stationsubsystem and mobile services switching centers and the like.The second part of the paper is the third to the fifth chapter, introduced softswitchupgrade process. The third chapter introduces SpatialAtrium mobile softswitch VOIP upgrade related to the BICC protocol, SIP protocol and H.248protocols. Second mobilesoftswitch the VOIP upgrade the specific steps, such as VOIP pre-upgrade checks toconfigure voice server module, configuration GIGE card, to configure Gigabit LAN IPaddress and configure the operation of the BICC TRUNK GROUP. The fourth chapterintroduces mobile softswitch MSC upgrade process. First, a brief under MSC relatedmodules and concepts. Then introduce the preparation needs to be done before theupgrade. Including data upgrade, upgrade MSC MSC process upgrade and upgrademodule checks. Chapter mobile softswitch upgrade test results and analysis. Includingthe ATC testing results and analysis, upgraded manual inspection of two parts.The final chapter of this thesis is a summary of the full text of this chapter isactually a summary of the full outlook with mobile softswitch. In this paper, the theoryand practice of mobile softswitch upgrade program. The softswitch theory has been verymature, including all of the standard and the specific networking, softswitchdevelopment is a long and tortuous road, although it has a lot of new technology withnew ideas, but the current situation can not completely replace the traditionaltelecommunications switch system, because it is there are some difficult issues, but weare still very happy to see the mobile softswitch development in the country is still verygood, many telecom equipment manufacturers not only to study the latest softswitchsystem, and even update the system version. The operators also actively promote thedevelopment of new technology. |
