Dimensioning The Interfaces In PS Domain Of UMTS Core Network

Since 1990's, the mobile communication market in which speech is the absolutely dominant role has experienced an unimaginable steep rise. And in the near future, it will continue to keep strong growth rates. But, In view of the continuous increase in global demand for data transfer, record growth rates for Internet links and access, together with the wish to make these services that have long existed in the fixed network sector also available in the mobile sector, all forecasts are predicting a steep rise in the volume of data transfers using mobile communication systems. Although the demand already exists now, expansion in these sectors was greatly hindered by cumbersome equipment, very low data transfer rates and overly expensive costs for the mobile transfer of data. All of these barriers will be overcome by the 3G systems.In present paper, Network Planning of UMTS (Universal Mobile Telecommunication System, one of 3G Mobile Communication Systems) Packet-Switched Domain of Core Network is analyzed.During the course of research, in addition to the specification and protocol defined by 3GPP, a number of correlative literatures are referred. Based on the theory of network planning, many formulae of the entity in PS domain and interface dimensioning are addressed and analyzed.With the respect to the theory of network planning, the concept and the objective of network planning, input parameters, planning process, traffic theory and overheads are all debated as the basis of latter planning.For the entity, According to the difference in function, three kinds of physical entity, including SGSN (Serving GPRS Support Node) which is...
