GPRS Network Resources Optimization

Measurement-based Optimization of the GPRS/UMTS Core Network

This is a document of the N2-METAWIN project. Its scope is to report on the exploitation of the data measured by the METAWIN system for the optmization of the Core Network. Specifically, we address the problem of finding the optimal assignement of Gb links to SGSNs. The optimality criteria are twofolds: balance the peak number of attached MSs to each SGSN, and at the same time minimize the volu...

Congestion analysis in a general GPRS network

This paper deals with congestion analysis of a GPRS network composed of N cells partially overlapping. In particular, we consider that one of the cells is affected by an outage and we analyze the effectiveness of applying a class of congestion treatment techniques that ultimately results in a switching of users from the congested cell to the others. In order to efficiently solve this complex sc...

Integrated Resources Optimization in Three-layer Dynamic Network

IP/MPLS over WDM is regarded as the best solution for NGN (next generation network), but in current and future for a long time, network architecture is still three-layer of IP/MPLS over SDH over WDM. In order to make full use of resources and reduce the blocking probability in three-layer dynamic network, an integrated resources optimization algorithm is proposed. We propose two optimization mo...

Optimization of Handover Margins in GSM/GPRS Networks

Optimization of handover boundaries has been suggested to cope with non-homogeneous traffic distribution in GSM/GPRS networks. In this paper, an automatic optimization algorithm is proposed, which is able to maximize the overall traffic carried in the network by equalizing long-term blocking effects. Field trial results indicate that system capacity can be significantly improved with respect to...
