On The GSM Network And Influence The Development Of IP Based

In recent years, with the GSM mobile communication network from the 2G to 3G networks, the network's high-speed, broadband network development has become the inevitable demand. Thus, the traditional TDM network to GSM-based networks can not meet, accompanied by the application of soft-switching technology, GSM network IP has become the inevitable trend of development of GSM networks.Major domestic telecommunications network operators, faced with this trend, and have unlimited behind the benefits are also sparing no effort to build and transform the existing communications network, in order to achieve the IP based network. As the 3 GPP R4 Mobile Softswitch relevant agreement matures, GSM networks first realized the IP based core network. Of which China Mobile, the largest GSM mobile communications network operator, no doubt walk in the forefront of the reform team. In 2004, China Mobile introduced the first in the tandem structure of soft-exchange separation. Through continuous exploration, the end of 2006 the successful completion of the first mobile softswitch network end office voice cut over IP, IP core network carrying voice and signaling used, through the construction of a dedicated, high-quality IP bearer network, IP bearer quality of service standards fully meet the telecom operators. So far, the reorganization of the three operators have basically achieved the IP core network side of the building.With the GSM core network IP transformation of the gradual completion of faster mobile networks to all-IP ahead, IP technology will permeate every aspect of the mobile network. The traditional IP network into a communications network has brought enormous change. Also gives operators a greater good, Such as:IP transmission network to replace traditional TDM trunk transmission network, increase network bandwidth at the same time, saving the metropolitan area network transmission resources; to more integrated devices, saving floor space and increase maintenance efficiency; the network tends to flatten, reduce network risk, etc., but also brought new problems:IP based network security risks increase after the original business and the entire network service area boundaries become increasingly blurred, the Council increased the amount of data produced and so on.IP based network is a systematic project, involving the transformation of the whole network is bound to the construction and operation of the existing network have a profound impact, this article will be based on the domestic situation of existing mobile networks, IP development process for the analysis of The significance of the evolution of IP technology, the basic course, the impact of the existing network, resulting in a problem and needs to pay attention and IP network maintenance for the design and development of the & quot;band network management system" introduced.
