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...
