Abstract
Increasing the number of mobile users, will cause more traffic can be accomodated. Traffic that exceeds the avaibility of the channel capacity can cause the Traffic Congestion Condition. A method is needed to handle the addition of channel capacity so that all traffic can be accommodated well. This method is called TRU Upgrading. Transmitter Receiver Unit(TRU) is a hardware that placed in Radio Base Station inside BTS which consist of some channels. TRU Upgrading method is a method to add/upgrade the channel capacity that available from TRU configurations that have been placed before, for example the BTS Pabuaran have 3x2x3 configuration, but due to the saturation of TRU customer it was upgraded into 3x2x3 configuration. TRU's configuration changing will also change the configuration of base stations and increase the channel capacity. A good Key Performance Indicator (KPI) on Indosat is using GOS 2%. This GOS value is related with Erlang's tables to get a traffic intensity;s value. When the traffic intensity's values that used are less than te intensity's value of costumer traffic, it is called traffic congestion. The result of this traffic congestion will make blocking cndition. TRU Upraging was used in condition to reduce the call blocking value became 0%. At Purwokerto's town area, TRU upgrading were applied on Grendeng 3's cell, Pabuaran 2's cell, and Unsoed 1's cell because of costumer traffic that occurs was exceed the traffic intensity values of the current TRU configuration. Although, Unsoed 1's cell and Grendeng 3's cell were applied TRU Upgrading into 4 pieces, but traffic congetion still occurs into 8-15 Erlang because this cells were coverage densenly populated area. As for PAbuaran 2's cell, this kind of method can achieve 100% effectiveness. Key words : Traffic Congestion, TRU Upradging, blocking, GoS
