Network model relies on appropriate channel model, LTE 3GPP specifications and well known schedulers are used. . Abstract—Aerial-Terrestrial communication networks able to provide rapidly-deployable and resilient communications capable of offering broadband connectivity are emerging as a suitable solution for public safety scenarios. During natural disasters or unexpected events, terrestrial infrastructure. . Most of the current research is based on the performance of the base station (BS) itself or the operation mode of the communication operator without considering the users' needs and signal overlapping coverage. Aerial base stations (AeBS) with flexible deployment capabilities stand as a pivotal approach, enhancing network capacity. .

Do communication base stations perform post-earthquake functionality using Bayesian network?
A method to evaluate the post-earthquake functionality of communication base stations using Bayesian network is developed. The dependence between the equipment and its hosting building structure, and the impact of power outages are considered. The method is validated using seismic damage data from the Ludian Earthquake.
Can a Bayesian network be used to assess communication base stations?
This study applies a Bayesian network method to the functionality assessment of communication base stations. The method integrates Fault tree analysis and Bayesian network, and its performance is validated through the observed seismic damage data of the Ludian earthquake.
How are communication base station data collected?
The communication base station data from different seismic sources are randomly combined and randomly divided into training set and test set according to the ratio of 7:3. 70% of the training set data are used for learning and 30% of the test set data are used for testing.
