Game-based data unloading method in heterogeneous wireless network

Abstract

The invention provides a game-based data unloading method in a heterogeneous wireless network. The data unloading method is characterized in that a macro cellular network operator provides data unloading excitation, and low power nodes deployed by other network operators competitively provide data unloading service for the macro cellular network operator under the condition of satisfying service demands of the own related terminal; based on a master-slave game theory, the situation that the macro cellular network operator can customize the optimal rental price to acquire the maximum return isdecided, and the quality of service of the macro cellular user terminal switched to the low power node can be guaranteed, and other network operators decide to sell the most suitable bandwidth to acquire the own maximum return. The data unloading method provided by the invention can achieve the advantages that the heterogeneous wireless network throughput is improved, the quality of the service ofthe user in the heterogeneous is improved, and the macro cellular data congestion is relieved.

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.
