Approximation Method for QoS Analysis of Wireless Cellular Networks with Impatient Calls
Heeyeol Eom,Chesoong Kim,Agassi Melikov,Mehriban Fattakhova 대한산업공학회 2010 Industrial Engineeering & Management Systems Vol.9 No.4
Simple-closed expressions for approximate calculation of quality of service (QoS) metrics of isolated cell of wireless networks with either finite or infinite queues of both new and handover calls are developed. It is assumed that both kinds of calls might leave the system without receiving service if their waiting times exceed some threshold value. For the models with infinite queues of heterogeneous calls easily checkable ergodicity conditions are proposed. The high accuracy of the developed approximation formulas is shown. Results of numerical experiments are given.

Purpose: The requirement for legal services is going up by modern people living in the era of complexity and variety who want to resolve legal conflicts between individuals and improve their personal rights. Methods: In this study we used both literature and empirical researches to achieve our goals. In literature research concept of service quality method of measuring service quality and dimension of service quality were explored relationship among service quality customer satisfaction and customer loyalty and hypothesis was made based on the above and tested. To test the conceptual framework structural equation modeling (SEM) has been used to analyze the data collected from 252 customers of Judicial Agents``s Service. Results: This result is not consistent with that of advanced study; it was found that service has significant influence on customer trust and the trust also has significant influence on customer satisfaction and loyalty. Conclusion: This study has limitations in terms of restricted service sectors and measuring methods. For this reason the followings are needed to be considered for interpretation and generalization of the study results. We believe that further studies are needed to investigate other service areas as well as legal service at the same time and study target which is limited to Gangwon Province needs to be expanded for more accurate investigation. In addition in-depth follow-up study should be proceeded considering variables such as customer value conversion cost and image of service providers.
