Shandong Td-scdma Core Network Planning

Along with the 3G commercialization advancement unceasing acceleration, 3G network each kind of equipment tests continues thoroughly, each operation enterprise positively is also carrying on the 3G network construction earlier period the network preparation.The Chinese government will possibly provide the mobile communication in the near future the 3G license plate. How is transiting smoothly from the present operation GSM migration network. The 3G network, must study the 3G network planning earnestly the method, prepares for the network planning ahead of time, will strive for in the future for the 3G network construction takes the initiative, only then will have the possibility to strive for the leading status in the future competition.This article has completed the Shandong 3G(TD-SCDMA standard) core network construction plan research and the design. Unifies the Shandong Province GSM network present situation, the utilization network planning theory, the basis plan flow, and considers GSM and the TD-SCDMA network coordination construction factor fully, From the enhancement plan quality, the network are advantageous for the development angle, had determined the Shandong TD-SCDMA core network initial period construction strategy, and unifies to the initial period plan network characteristic analysis, has formed the Shandong TD-SCDMA core network initial period construction plan plan.The concrete plan indication is: GSM and TD-SCDMA use in common the core network, simultaneously supports GSM and the TD-SCDMA wireless turning on technology; The core network uses based on 3GPP the R4 standard lamination network architecture; The network redundancy uses MSC in Pool, HLR 1+1, SGSN in the Pool technology, provides the redundancy guarantee for the network; MGW supports Iu and the A connection nimble connection; Uses the IP technology, the pronunciation and the grouping territory data all based on unifies the IP net transmission.This article studied has followed first the fundamental research, latter practiced the application the research technique. Through to the TD-SCDMA network construction characteristic, the key technologies understanding and the analysis, systematically advanced the TD-SCDMA network construction plan elementary theory and the plan content, the method.
