Optimización en una red de conmutación de paquetes móvil 3G

Abstract

The 3G network traffic has grown exponentially and therefore the efficiency Operational is an even more urgent issue than it has been until now. The immediate challenges that are projected demand a more powerful network. More efficient and intelligent networks, capable of better managing the growing traffic demand; A more efficient transport network; More efficient software; More efficient services. Our modern world has made the network a new environment from which arises the growing demand for data and voice that users demand to the mobile network. Every time users have smart electronic devices and terminals with connection to social networks and other applications that require a reliable and stable network connection. All these services that allow a large amount of information in the cloud to access at any time with the same quality in data transfer, this at the same time generates increased traffic causing the network to saturate. This work focuses on the optimization of the traffic that is transported through the IuPS interface of the 3G network, which is the physical connection between a RNC (Radio Network Controller) and a SGSN (Serving GPRS Support Node), currently the traffic that controls the RNC is handled by a single SGSN and when bottleneck or network saturation occurs the data is discarded, to solve this problem we propose a solution that changes the architecture that is established in the 3GPP standard, this proposal consists of a multiple connection for the IUPS interface and traffic of a single RNC will be attended by a group of SGSN. As a result of the redundancy at SGSN level with this new proposal to the architecture of the IuPS interface, a greater availability of service is guaranteed avoiding transmission errors. The subscriber shares data between different SGSNs that are serving in the same area of ​​the balanced group the weights for each of them according to their capacity, which significantly improves management by load balancing. The decrease in signaling load due to the reduction of routing area updates between the SGSNs is remarkable. In addition, easy updating and maintenance reducing the impact of network errors leads to a significant improvement in statistics.
