Based On Softswitch Technology Of Mobile Core Network Design

The current rapid development of communication technology, and technology are advancing with each passing day, At present, as the leading communications business--especially mobile communications. Growth in the number of mobile subscribers to the operations' network expansion has brought enormous pressure. Limited network resources and how to solve the ever-increasing conflicts between users so that a more rational structure of the network. is a technical problem currently plaguing operation. Most of the current use of 2G mobile communications equipment, network capacity and upgrading technology there are some limitations. Soft-Switch equipment and the introduction of the 2G network. At present 2G network to the core network expansion and upgrading have provided a workable solution. also more reasonable in terms of investment.From the background and purpose of the discussion, the dissertation first introduce the principium of Softswitch, the development of standard protocols and the application of Softswitch in the global.Then from the point of view of combining practical application of engineering design case described in detail the "core of a GSM network operators expansion" project. As a writer for the project, according to the actual operation of the network operations and maintenance. as against the existing GSM core network equipment. Soft switching equipment for the new network optimized for the specific network expansion program. After repeated discussions with the operations together with the study, improve design. The program is the ultimate in network smoothly. Soft-Switch thesis focused on GSM core network equipment in the network, then the program include : road network, the signaling network. transmission network and redundant disaster; Meanwhile, the core network to the 3G evolution of the program are discussed in detail.
