چکیده
In this paper, an analytical approach for estimating the network capacity for voice communications on LTE-based public safety networks is presented. The network is modeled using Markov birth and death process. In order to provide the required Grade of Service for LTE-based public safety users, the minimum number of channels required for different levels of users’ priority is calculated. The results for some performance metrics such as throughput, delay probability, and channel utilization are obtained. The results obtained from the simulation is compared with the existing network model such as Erlang C. Results show that the existing network model show similarities and differences in predicting the channel estimation of the deployed LTE networks for public safety communications. The results can help the network designer in the proper dimensioning of LTE-based public safety network.

Public Safety Communication over 3GPP LTE
The 3rd Generation Partnership Project (3GPP) is ready to present a new cellular network standard; Long Term Evolution (LTE). LTE improves communication for public safety users like police, medical, and rescue workers in cellular networks. This creates a need to examine whether LTE can satisfy public safety users requirements. This thesis has a focus on group communication with a voice service....
