Automatic Traffic Load Distribution

Abstract [en]

Continuous increase in amount of cellular phone users, demand constant progress of methods for extending the radio network capacity. Two features that are used to increase the capacity today is CLS (cell load sharing) and offsets. Offsets and CLS increase the capacity in the radio network through distributing mobiles located in cells with high traffic load to cells with less load. The CLS takes care of the rapid changes and the offsets take care of the slow varying changes of the traffic. The parameters that control the CLS and the offsets are today set by hand, which can be both tricky and time consuming. The purpose of this thesis work is to investigate a new type of locating algorithm [1], which consist of two parts, the offset and the Quality-Based- CLS. In this thesis the two features are meant to be set adaptively. The evaluation of the algorithm is performed through an investigation of the ability to even out the load among the cells and still maintain the quality in the cellular network. The evaluation is carried out for the different parts by them selves, as well as together for the possibility to see the effect of each part in the algorithm. The results show that the new locating algorithm have potential to increase the capacity in the radio network through even out the traffic load in the system and still maintain the link quality for the connections.
