Game theory-based graded pricing frequency spectrum resource management method

Abstract

The invention relates to a game theory-based graded pricing frequency spectrum resource management method and provides a new graded price mechanism, the mechanism can define dynamic prices for users with different grades in a heterogeneous network, and the graded structure can ensure the priority requirements of different user services, thereby ensuring the benefits of the user of a main system and simultaneously considering the needs of the users of cognitive systems. The method can not only fully utilize the limited frequency spectrum resources, but also ensure the fair and reasonable competition between the cognitive users and the main user and between the cognitive users, and avoid the status of overhungry or satiety in the resource utilization; and the graded price mechanism is the unilateral voluntary selection mode of the cognitive users and applicable to the underlay sharing way, that is the main user system can accommodate the cognitive users as much as possible within the interference bearing capacity and carry out pricing through gaming among the users at the same grade according to the service grades of the cognitive users, and each cognitive user can select to accept the price of the main system or not according to the respective cost. The method is established on the basis of reasonable modeling of user services, mobility and the like.

Description

technical field [0001] The invention mainly solves the radio resource management (RRM) problem in the wireless cognitive communication network, and discusses the spectrum resource management strategy therein. In the environment where the cognitive network and the main system network are heterogeneously coexisting, establishing a reasonable pricing mechanism and taking the game-based price mechanism as the core of resource management is an effective way to solve the shortage of spectrum resources in wireless networks. The spectrum resource management scheme based on hierarchical pricing can not only make full use of limited spectrum resources, but also ensure fair and reasonable competition among cognitive users, primary users, and cognitive users, and avoid starvation or oversatiation of resource utilization. situation. Background technique [0002] Faced with the problems of diversification of network services, increasingly tight resources, and coexistence of multiple netw...

Problems solved by technology

The competitive mode can maximize the local benefits of individual base stations, but the overall performance of the network is often not optimal, while the cooperative mode can maximize the global benefits of the network, but often at the expense of the interests of local base stations

In addition, the existing price competition mechanism does not take into account factors such as user costs and different needs, and has not established links with other wireless resource management aspects such as RAT switching, resource scheduling, configuration, and power control. In fact, the base station The proposed price has a fundamental impact on the above aspects. This impact determines the user's choice of RAT, user cost, and QoS guarantee in a heterogeneous wireless network.

[0005] To sum up, the problems existing in the wireless resource management in the existing heterogeneous network mainly include: (1) the overall benefit and the overall system performance cannot be balanced, and the global benefit and the local benefit cannot be balanced; (2) the existing price competition mechanism does not Failure to take into account factors such as the user's business model, mobility model and network behavior, and not establish a link between resource prices and other aspects of radio resource management such as RAT handover, resource scheduling and configuration, and power control
