“…Again, from Table 11, outage probabilities of all algorithms are below 0.05. Besides, we compare the proposed traffic aware algorithm with the cell load based algorithm in [11] in which the utility function is determined based on the number of active users in the BSs and the RSSI values. Based on the performance results, the proposed traffic aware full set algorithm reduces the average waiting time about 10% further in all environments.…”

“…The goal of the proposed traffic aware full set cell selection algorithm is to reduce call setup while the objective of the proposed traffic aware reduced set cell selection algorithm is to minimize also the number of RSSI measurements. Compared to the our previous works in [11] in which the cell load has been calculated by using the number of connected users, in this work, we determine the traffic load based on the call duration in a realistic Tetra Trunk scenario including a cell re-selection procedure.…”

Load balancing and traffic management are the critical needs in cell selection decision for a better and seamless communication demands in professional mobile radios. For the cases where cell selection algorithms do not consider the traffic load, there may be call drops due to the congestion in networks or longer call setup times for the users. These undesired consequences can cause dramatic quality degradation especially for the emergency cases or public safety services. In this paper, we propose two algorithms for Tetra Trunk based professional mobile radios by considering both traffic load and received signal strength indication (RSSI) in order to reduce the significant delays while establishing transmissions. The proposed full set cell selection algorithm is prioritized to reduce the call setup time for the mobile users and the proposed reduced set cell selection algorithm is focused on minimizing the number of RSSI measurements which causes significant delay in practical professional mobile radio. We illustrate the performance results in terms of delay for Tetra Trunk based professional mobile radio.

“…In [13], the utility value was determined by considering the number of active users and received signal strength indicator (RSSI) values. In [14], the cell load-based cell selection algorithm was applied to TETRA Trunk instead of the DMR system. The main difference between TETRA Trunk and APCO25 conventional systems is that the coverage area of BSs for TETRA Trunk systems is considerably less, which means that more BSs are needed for the same given area.…”

Wireless communication between public safety officers is very important to transmit voice or data during emergency crises. When the public communication networks cannot provide services during crises, disasters, and high traffic cases, Professional or private mobile radio (PMR) such as Association of Public Safety Communications Officials (APCO25) conventional systems are needed to improve the service quality and to provide uninterrupted service to the users. In this paper, we propose traffic-based cell selection algorithms for the APCO25 conventional systems to attach users to base stations in a balanced manner to reduce waiting time while establishing a connection. The simulation results of the proposed traffic load-based cell selection algorithms are illustrated in terms of the RSSI measurements counter, the number of connection requests, the average waiting time, and the number of re-selections for the APCO25 conventional systems.
