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...

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.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a technique for optimally allocating bandwidth resources of a heterogeneous fusion network. Background technique [0002] With the rapid development of various communication technologies and the continuous growth of user service demands, various existing wireless access technologies will converge and coexist to provide effective access services for various user services. Various typical access technologies include wireless personal area network, wireless local area network, wireless metropolitan area network, public cellular mobile communication network, satellite network, and mobile ad hoc (Ad Hoc) network. figure 1 The example shown is a heterogeneous converged network. Multi-network terminals can use wired interfaces or wireless interfaces through wired access technologies (such as cable TV network, wired network 802.3) or wireless access technologies (such as GPRS (Gener...
