Load based cell selection algorithm for Tetra based professional mobile radio

This paper proposes a cell selection algorithm for Tetra based professional mobile radio systems where the users select the base station according to the proposed utility value. This utility value is determined by considering both cell load and received signal strength indicator. The main aim of the proposed method is to distribute the users in a balanced way among base stations. Based on performance evaluations, we illustrate that the proposed cell selection algorithm gives better results than Tetra based cell selection method in a manner of distribution of the users over all BSs while reducing waiting time for establishing connection.
