[0004] The purpose of the present invention is to propose a spectrum auction method for dynamic traffic sharing of the cellular network in view of the dynamic change of the load of the cellular network and the third-party base station in time. The change of traffic data load within a day can not further improve the efficiency of traffic sharing. Under the condition of considering the change of traffic data load of cellular network and third-party base stations within a day, an anti-auction model is established, and the time period is divided. Spectrum Reverse auction, establish the objective function of the auction, and find the optimal solution through the Lagrangian relaxation method, and minimize the shared cost of the cellular network operator while meeting the traffic sharing goal at any time

Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with accompanying drawings and examples.
[0022] The present invention establishes a reverse auction model to realize the dynamic traffic sharing in the cellular network, as shown in the attached figure 1 shown. The anti-auction model includes the cellular network and third-party base stations. According to the historical data of the traffic data load changes of the cellular network and third-party base stations within a day, it predicts the changing law of the traffic data load of the cellular network and third-party base stations in the future. Network and third-party base station traffic data load change prediction is based on the existing BP neural network traffic prediction model;
[0023] The auction control center divides a day into K time units according to the load change of the cellular network, e is the length of the time unit, the size of e is determined by the auction control...

The invention discloses a spectrum auction method for dynamic traffic sharing of a cellular network. The method establishes an anti-auction model under the condition that the traffic data load changes of the cellular network and a third-party base station within a day are considered, divides time periods, and performs spectrum anti-auction. For the auction, the objective function of the auction is established, and the optimal solution is obtained through the method of Lagrangian relaxation, and the shared cost of the cellular network operator is minimized while meeting the traffic sharing goal of any time period. The present invention can well realize the minimum sharing cost of the cellular network operator while satisfying the traffic sharing target at any time period, is easy to implement, and is convenient to expand. Compared with the traffic sharing method that has been proposed, it has higher traffic sharing efficiency and can Effectively improve the throughput and spectrum utilization rate of the cellular network and improve the communication quality of users.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a spectrum auction method for dynamic flow sharing of a cellular network. Background technique [0002] With the rapid growth of the number of users and business volume of the cellular network, the demand for bandwidth also increases rapidly, which poses a huge challenge to mobile network facilities. The data traffic generated by a large number of mobile users exceeds the capacity of the cellular network, thus deteriorating the quality of network service provided to mobile users. The most immediate solution to such a challenge is to increase the capacity of the cellular network, however, increasing installation and management costs may limit the bandwidth required to provide access to the Internet through additional deployment of new base stations. In order to solve the above problems, some scholars are committed to finding more effective ways to increase the capaci...
