Abstract
This paper contributes to the evolution of public safety communication networks by specifying a solution for managing the radio resources of multi-agency Terrestrial Trunked Radio Enhanced Data Services (TEDS) networks. A TEDS network can be securely partitioned so that different public safety agencies such as police, fire, ambulance, etc. can share a single network’s infrastructure including base stations and main switches. This sharing feature offers a cost-effective solution not only for network investment, but it also helps to reduce the costs of network operation, implementation and maintenance. The real implementation of TETRA sharing is not easy because radio resources and other shared resources must be managed among all agencies in an efficient and secure way. Without an efficient radio resource management (RRM) policy, one agency can exhaust the capacity of others. This study proposes a radio resource allocation scheme to provide maximum system throughput and proportional fairness in accordance with agency capacity, which is shared through a dynamic resource allocation scheme. The performance analysis of this scheme in terms of throughput, bounded delay and queue size are obtained. Numerical and simulation results show that the proposed dynamic partitioning-based rate RRM scheme, referred to as DP-RRM, improves both system throughput and average delays.
