Sgsn Pool Application Sdudy And Planning&Design In Hubeimobile Core Network

SGSN POOL technology is the centre of attention in core network construction at present. On the technology itself, through network resource sharing,it ease traffic tidal effect,balance the imbalance traffic between different nodes,improve network valuability; through a multi-node distributed deplayment, it implement non-interrupt tarffic disaster recovery and backup,enhance the network reliability; through reducing signaling switching and signaling traffic,it raise switching success ratio,improve traffic quality and promote system performance. SGSN POOL uses distributed deployment for centralized maintenance, which simples network maintenance, raise OAM efficienty, decrease OAM expenditure.Based on these advantages,SGSN POOL was applied to the aborad operators, and it is been proactively introduced into CN by China Mobile. By studied on2G/3G core network constructing, the configure requirement of natural parameter, switching and user updating in pool networking and pool aera division, according to overall principles and process in pool planning, on the basis of the present user traffic distribution and aera divising situation, go on and probe into to SGSN POOL network scheme in Hu Bei mobile core network(ps aera), the paper proposes importation strategy of introducing SGSN Pool into Hu Bei Mobile services aeras.
