Optimization Downlink Power Utilization via Dual Beam Antenna in the Live UMTS Network製作日数365日間希望販売価格3,000円～10,000円未満There are four route cause problems in a live UMTS network congestion which are power congestion, Channel Element congestion, Iub congestion, and DL (Downlink) Code congestion, which affects the use of the user experience cause customer complain later. This paper proposes optimization downlink power utilization by applying Dual Beam antenna to decrease downlink power congestion from number of Soft Handover Overhead (SHO) because while UE clamp on 3 active set (3 radio links) in live UMTS network. The Soft Handover Overhead must be increased by itself this is the problems caused by multiple cell overlapping coverage between sectors. Than for solution to the optimization via Dual Beam antenna can improve and decrease number Soft Handover Overhead (SHO) in live UMTS network. We can define by 2 counters to measure DL power congestion by TCP (Total transmission Carrie) counters as name VS.MeanTCP: mean carrier transmit power in a cell, VS.MeanTCP.NonHS: mean downlink carrier transmit power for non-HSDPA in a cell (R99).The experimental results shows that the VS.MeanTCP increased to 50% and VS.MeanTCP.NonHS increased to 50%.

Optimization Channal Contral Power in Live UMTS Network製作日数365日間希望販売価格3,000円～10,000円未満Optimization Channel Control Power in Live UMTS Network : The proposed approach to improvement on the UMTS (Universal Mobile Telecommunications System) network radio, there are many ways we propose another way of reducing power control channel slightly to provide improved signal quality, which is a measure of quality is EcIo (energy per bit) / (Own cell interference +. Noise density) principle when the power control channel down a bit to make the quality better, because the denominator less energy than ever before, and open the extra capacity in the network in the body, this is the reason for the optimization this principle can be applied in a live network. It is important to maintain signal quality are durable and resistant to interference. Probability to the good benefits for imply network must be physical tuning coverage complete before and area dense urban or urban is good to the imply this parameter. For area rural should not imply because the cell edge a foot print coverage is too large . However this paper presents a science so that the results can be applied to real work.
