The Research On 4G User Perception Based On Entropy Method In K Company

With the rapid development of 4G communications in China,competition in the Chinese 4G market is increasingly fierce.The top 3 telecommunication service providers seize and enlarge their share of market by improving the quality of service in 4G services.So it is crucial to research how to assess the 4G services from the point view of customers.This research based on the ‘Factor identification-Factor evaluation-Case study' theory for the 4G user data analysis and from the point of view of customers' perceived value as we conduct our research and figure out 4G user perceived score.We collected data from telecommunication service provider Data Warehouse system,sorted out 20 factors to establish a 4G service evaluation model which based on metrics of service perceived value,service charges perceived value,net work perceived value,end mobile devices perceived value.Secondly,we also figure out weight of all factors based on the entropy theory,using ? Feature Selecting method to select 20 indicators which have significant impact on customers' perceived value of 4G service and after we weighted and normalized different factors such as 4G user complaints,call competitor times,average revenue per user,main parkage fee,we form a customers' perceived value based 4G service evaluation system.We can distinguish most likely loss of clients base on then method and reduce the customer loss rate.In conclusion,with the application of ? feature selecting and entropy method,this paper established the evaluation model of 4G service based on user perceived value.Our purpose is that we find out the purchasable motivations of customers and promote our products or services in compliance with customer's requirements.
