Wireless resource allocation method and device

Abstract

The invention relates to a wireless resource allocation method and device, relating to a communication technology. The wireless resource allocation method comprises the steps of: determining priority of a user according to user information reported by the user; determining a propriety of allocating wireless channel resources to each user according to the priority of each user; and allocating the wireless channel resources to each user according to the priority. Because the priority is provided for each user, and when the user accesses the network, the wireless channel resources are preferentially allocated to the user with high priority, thus the access service quality of the user with the priority is guaranteed. In addition, after the user with high priority accesses, service regulation influences of load congestion control, speed reduction and other algorithms to the user with high priority in the traditional wireless resource management algorithm are reduced, and further the network online time of the user with high priority is prolonged through starting a delay timer method.

Description

technical field [0001] The present invention relates to communication technology, in particular to a wireless resource allocation method and device. Background technique [0002] At present, in the case of major natural disaster rescue and relief, emergency public events, large-scale gatherings, etc., there will usually be a large number of sudden calls, which will easily cause network congestion; Important personnel will lead to the inability to provide wireless resource allocation protection for important personnel such as activity commanders; in the case of network congestion, public wireless services for important personnel will be seriously affected in terms of access and bandwidth guarantee. [0003] At present, in terms of user wireless network resource allocation, the wireless system handles important users with higher priority in the same way as ordinary users, and does not distinguish them. Especially in the user access link, the authority of important users and ot...

[0006] 2) Round Robin (RR), for all users connected to the network, according to a certain order, the wireless resources of the same time are cyclically occupied for communication, and try to ensure that the resources of the same size can be allocated to them with equal opportunities. Each user in the system fully guarantees the fairness of all users, but the system throughput is usually the lowest, and there is no distinction between high-end and low-end users' priorities for wireless resource occupation;

[0007] 3) Proportional Fair algorithm (Proportional Fair, PF), which assigns a corresponding priority to each accessed user, and the priority is based on the maximum service transmission rate of the user at a certain time point and the average value of the user before that time point. In this way, in a system with multiple users, when users communicate continuously, their average service rate will gradually increase, and their priority will decrease, and subsequent services will not be available.

[0009] Therefore, when an emergency occurs and the resources of the cell are insufficient, users with higher priority may be preempted by other ordinary users during the access process and the resources will be released, or the access may fail due to lack of network resources.

After accessing the network, the existing wireless resource allocation and scheduling method also considers the fairness among users and the throughput of the system, and cannot guarantee the service quality of users with higher priority.
