The objective of the present research is to build an empirical Lotka-Volterra system using real-time data and information from the postpaid and prepaid mobile telecommunications subscribers in the OECD area. Genetic algorithms are used in order to specify the appropriate coefficients of the corresponding predator-prey competition system, where the pre-paid subscribers hold the role of the predator...
This paper researches the demand function of the per capita consumption of mobile voice service by fixed effect quantile regression model. Results show that both price elasticity and income elasticity vary between different consumption-level consumer groups. For low-consumption consumers, income is the most important factor that impacts their consumption, while the price of mobile voice service and...
This paper provides a general analytic method to estimate the handover rate in mobile packet systems with heterogeneous cell types and multimedia services. The handover rate is derived as a closed-form function of the Laplace transform of the session time distribution. The proposed model can be easily extended to analyze the mobility feature of the heterogeneous mobile systems with hierarchical cell...
