Optimal Allocation Method of Bandwidth Resources in Heterogeneous Converged Networks

Abstract

The invention discloses a heterogeneous converged network bandwidth resource optimizing distribution method based on utility function and bankruptcy game theory, and belongs to the technical field of communication. By optimizing the bandwidth demands of users in a common coverage area of a heterogeneous radio access network, user services are categorized, a network association utility function is modeled, and a bandwidth resource optimizing distribution scheme for various services in networks is obtained by maximizing the network utility function under the condition of meeting the bandwidth demands of the various services. Further, a bankruptcy game model is established, and a bandwidth optimizing distribution scheme for the users is obtained by solving the Shapley value. Cooperation and competition relationships between the networks and between the users are comprehensively considered, overall network gains are optimized under the condition of equitable distribution of various service resources by means of joint resource management, and access bandwidths of the users are reasonably and effectively distributed based on the game theory, so that network resource utilization rate and QoS (quality of service) of the users are improved.

AI Technical Summary

Problems solved by technology

Since user service experience and network performance are complex system issues that are affected by multiple factors such as bandwidth occupied by users, competition among users, and the price paid by the network for providing services to users, it is difficult to model mathematically.

On the one hand, each access network takes the maximization of its own revenue as the goal of resource allocation and performance optimization; on the other hand, the fierce competition for user resources among the access networks leads to the maximization of the independent revenue of each access network can not achieve
