Method for sharing frequency spectrum resource of isomerism wireless network and device thereof

Abstract

The embodiment of the invention provides a method for sharing frequency spectrum resource of an isomerism wireless network and a device thereof. The method comprises the following steps: a bandwidth requirement of a current network in designated time is predicted; if residual bandwidth resource of the current can not meet the predicted bandwidth requirement, then other wireless network bandwidth resource in the same overlay area is searched, then bandwidth resource dispatch is carried out on the searched wireless network which has useable and unoccupied bandwidth resource so as to meet the predicted bandwidth requirement of the current network. Therefore, the method effectively improves the utilization rate of wireless resource of the isomerism wireless network, the access rate of customer service and the throughput of the system, thus improving the performance of the system.

Description

technical field The present invention relates to the field of network communication, in particular to a method and device for sharing frequency spectrum resources of heterogeneous wireless networks. Background technique With the rapid development of communication technology, a variety of wireless networks have emerged and constitute heterogeneous wireless networks. However, due to the limited available spectrum resources, it still cannot meet the needs of the rapid growth of wireless services. At the same time, many studies have shown that there are very serious idle and waste phenomena in the allocated spectrum resources, and the utilization rate of most of the allocated frequency bands is between 15% and 85%. Therefore, it is an urgent problem to study a reasonable spectrum resource sharing scheme and effectively utilize its spectrum resources in a heterogeneous wireless network to provide users with better services. At present, research on rational use of idle resources...

Problems solved by technology

However, due to the requirement of its design scheme to avoid the primary user in time, and the processes of these methods are often very complicated, the additional overhead of the system is relatively large; at the same time, there is a lack of spectrum sharing in heterogeneous wireless networks with a joint resource management mechanism in the prior art Scheduling technical solutions, so that the utilization of wireless resources has not been effectively improved, affecting the performance of the system
