Radio resource sharing in multi-agency TEDS networks

A Terrestrial Trunked Radio Enhanced Data Services (TEDS) networks 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. 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 an adaptive 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 adaptive rate sharing RRM allocation scheme improves both system throughput and average delays.
