Research On Secondary Traffic Management And Pricing In Mobile Communication Networks

With the increasing demand for mobile data communication,mobile communication operators need to invest a lot of money to expand the capacity of mobile communication networks.However,since the user's data traffic demand is unevenly distributed in time and space,and the network capacity needs to be planned with reference to the peak demand,the overall utilization rate of the mobile communication network is low,and there is a large amount of redundant capacity.The opportunity content delivery network proposed in the recent literature can dynamically utilize the redundant capacity to provide users with low-price secondary content delivery services.The traffic generated by the secondary service is also called secondary traffic.This paper aims at maximizing the profit of operators,and conducts research on the optimization of secondary traffic pricing and management strategies.The main research contents and contributions of this article include two parts.Firstly,this paper considers the basic scenario of user-oriented charging and analyzes the management and pricing strategies of secondary traffic.We propose three representative functional relationships to quantify the sensitivity of the user's secondary traffic consumption behavior to the traffic price.On this basis,the optimal secondary traffic price under a given redundant capacity is deduced.In addition,a mechanism for pre-pushing content using secondary traffic is further proposed.The relationship between the cost of pushing traffic and profitability is comprehensively considered and the problem of optimal pre-pushing traffic is solved.The numerical results show that compared with the non-preemptive mechanism,the use of the secondary traffic pre-adjustment mechanism can effectively improve the operator's profits.Secondly,this paper further considers the complex scenarios in which content provider can provide users with free secondary traffic sponsorship,and analyzes the operator's-content provider's win-win secondary traffic management and pricing strategies.We use the Stackelberg model of game theory to model the profit-related parties.The operators decide to determine the prices of content provider and users who use secondary traffic,and the total profit of the system is distributed between operator and content provider.We analyzed the maximum amount of sponsorship(optimal strategy)of the content provider when maximizing the total profit of the system,and derived the influence of the secondary service pricing on the total profit of the content provider.The results show that when the content-oriented provider's pricing for the secondary traffic is within a certain range,the traffic sponsoring mechanism can effectively increase the profits of both the operator and the content provider,and achieve a win-win situation for both parties.The research in this paper shows that reasonable secondary traffic pricing and management strategy can bring significant profits to mobile operators.Therefore,the secondary content delivery service provided based on the redundant capacity of the mobile communication network is a new type of mobile communication service with good commercial prospects.
