A Game-Based Data Offloading Method in Heterogeneous Wireless Networks

Abstract

The present invention proposes a game-based data offloading method in a heterogeneous wireless network, which is characterized in that in the heterogeneous network, the macrocellular network operator provides data offloading incentives, and the low-power nodes deployed by other network operators satisfy their own association Under the service demand of terminals, they compete to provide data offloading services to macro cellular network operators. Based on the master-slave game theory, it is decided that macro cellular network operators formulate the optimal lease price to obtain the maximum profit, while ensuring switching to low-power nodes. The quality of service of macro-cell user terminals, other network operators decide to sell the most suitable bandwidth to obtain their own maximum benefits. The beneficial effects that can be achieved by the present invention are: improving the throughput of the heterogeneous wireless network, improving the service quality of users in the heterogeneous network, and alleviating the macro cell data congestion.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a game-based data unloading method in a heterogeneous wireless network. In the heterogeneous wireless network environment, the method determines the optimal lease price of a macrocellular network operator based on a master-slave game And the most suitable bandwidth for other network operators to sell, through data offloading to alleviate macro cell data congestion, while ensuring the quality of service requirements of associated terminals. Background technique [0002] With the rapid development of smartphones and mobile broadband services, the surge in mobile data traffic poses new challenges to current cellular networks, especially causing network congestion and overloading, which degrades user experience. Macrocell network congestion can be alleviated by upgrading the macrocell network or deploying more macrocell base stations, however, these solutions r...

Problems solved by technology

[0003] Purpose of the invention: In order to solve the above technical problems, the present invention aims at the fact that traditional macro cellular networks are prone to network congestion and overload, unable to meet the ever-increasing demand for user data traffic, and the low-power network nodes deployed by other network operators have no economic rewards. In this case, the macro cellular network operator is unwilling to provide the necessary network resources for data offloading. A game-based data offloading method in heterogeneous wireless networks is proposed.
