Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
In order to effectively improve user satisfaction and base station revenue, the application introduces a game theory (game theory) model. The game theory model has been proposed in the past for non-cooperative wireless communication, which is a powerful framework for analyzing interactions between multiple participants acting on their own interests. The main idea of the game is that after the leader makes a decision, the follower makes a decision according to the decision of the leader, and then the leader adjusts the decision of the follower according to the decision of the follower, and the steps are repeated until Nash equilibrium is reached. At this time, both the leader and the follower select their own optimal strategies to maximize profits. The game theory is recognized as the best mathematical tool for researching the mutual influence and behavior interaction of different main body decisions.
Assuming that both the base station and the user are selfish and rational, it is clear that both parties explicitly want to get higher profits. The base station wants to sell more bandwidth resources at a higher price, while the user wants to buy as much bandwidth resources as possible at a lower price. In the game, the base station is used as a leader to carry out pricing game, and the user is used as a follower to carry out demand game.
The following describes a monitoring service bandwidth allocation method, apparatus, electronic device, and storage medium according to an embodiment of the present application with reference to the drawings. In the method, based on a multi-base station and multi-user interaction scene, the influence of path loss between each user and each base station is considered, and a two-stage Stackelberg game taking a dynamic bandwidth allocation strategy and a pricing strategy as constraint conditions is constructed. Firstly, the reliability of the base station is ensured through a bandwidth allocation strategy, then a dynamic pricing strategy with cost effectiveness is constructed on the basis, and an optimization problem is made by maximizing the utility of users and the base station. The method effectively guarantees the experience quality of the user and the income of the base station, and realizes the effectiveness of bandwidth allocation. Therefore, the problem that bandwidth cannot be allocated according to different user requirements in a differentiated mode is solved.
In the embodiment of the present application, as shown in fig. 1, it is assumed that all edge base stations deployed by the operator are aggregated intoN={1,2,...,n,...,NAt the same time, a group of mobile users is represented asM={1,2,...,m,...,M}.

In one embodiment of the present application, determining a pricing strategy includes: and acquiring a corresponding dynamic pricing strategy according to the total bandwidth request quantity of each user to the base station.
It can be understood that, according to the channel information, the user requests the base station for service on demand, as shown in fig. 3, specifically including:

The allocation strategy ensures the reliability of the base station. When the resources of the base station remain, the new user can also continue to request service from it, which can ensure the maximum number of user accesses. In addition, in this case, the service cost of the base station is also determined by
