Abstract:Public safety involves the prevention or protection from emergence events that could cause danger, injury and damage to the general public. Public safety is considered as the largest Professional Mobile Radio market that is served by Terrestrial Trunked Radio (TETRA). TETRA specifies some mission-critical services that can be used in public safety communication system. Currently, three main network scenarios are identified to support these mission-critical services. These three network scenarios are tactical patch, expanding coverage and migration to other network. Within the mission-critical network, interconnection of different users in these three main network scenarios becomes an interesting issue. MPLS (Multi Protocol Label Switching) based IP networking solutions could be utilized to satisfy the requirements imposed by mission-critical services. Therefore the main goal of this thesis project is to specify, design and evaluate an architecture for the interconnection of heterogeneous communication systems using MPLS based IP networks for mission-critical group oriented communications. In this research, a core network architecture has been designed. To show how the core network architecture can support group communication, we defined message sequence charts for the main features that are supported by the core network. We evaluated the core network architecture with respect to the scalability. Scalability is measured by calculating the number of signaling messages (i.e., signaling load) per selected feature when the number of wireless access networks supported by the core network is increased. Based on the calculation, some graphs associated with the selected features are generated to indicate the performance behavior of various signaling messages for the main features.
