Embodiment Construction

[0054]Preferred embodiments of the present invention will be described herein below with reference to the accompanying drawings. In the following description, known functions and constructions are not described again since they would obscure the invention in unnecessary detail.

[0055] The present invention provides a method for dynamically allocating and managing heterogeneous network wireless resources in terms of time and spectrum. According to the characteristic parameters of different service requirements, the priority of different users to obtain wireless network resources is determined, and the heterogeneity of available network resources, Time-varying, heterogeneous and time-varying user services are used as the basis to dynamically adjust and allocate wireless network resources to achieve fairness and effectiveness in user resource sharing. The specific implementation method is as follows

Abstract

A heterogeneous customer service executing coefficient introduced dynamic resource scheduling method relates to a method and strategy for dynamically scheduling time and frequency spectrum resources (wireless channel) for a plurality of customers with different service requirements in a heterogeneous wireless network environment containing cognitive radio technical equipment, in particular to a method and strategy for dynamically scheduling and allocating opportunistic frequency spectrum on time and frequency band and making the customers with the different service requirements in the heterogeneous network fairly and effectively use finite wireless network resources. The dynamic resource scheduling method comprises the following steps: considering customer service characteristics into network resources for the first time, including dynamic allocation of the time and frequency spectrum resources; defining a customer service executed priority coefficient by various parameters deciding customer service types, and sorting heterogeneous customer services according to the priority coefficient so as to obtain basis for effective allocating finite available channel resources; on the basis, allocating available channels according to the principle of maximizing the frequency spectrum utilization rate; and obtaining service quality guarantee for the customers with the different service requirements.

Description

technical field [0001] The present invention generally relates to a method and strategy for dynamically scheduling time and spectrum resources (wireless channels) for multiple users with different service requirements in a heterogeneous wireless network environment including cognitive radio technology equipment, more specifically , relates to a method and strategy for dynamically scheduling and allocating opportunistic spectrum in time and frequency bands, and enabling users with different service requirements in a heterogeneous network to use limited wireless network resources fairly and effectively. Background technique [0002] Currently, the utilization of wireless spectrum resources is extremely unbalanced: some licensed frequency bands are highly occupied, while some licensed frequency bands are often idle. One of the effective ways to solve this phenomenon is opportunistic spectrum access technology. Opportunistic spectrum access technology allows opportunistic devel...
