A scheduling method for ensuring multi-service qos in a power wireless communication system

Abstract

The invention discloses a scheduling method for guaranteeing multi-service QoS in a power wireless communication system. The steps of the method are as follows: Divide the various services to be scheduled in the system into real-time services and non-real-time services; before the start of each scheduling cycle, calculate the real-time services according to the transmission rate and data waiting time under the current channel scheduling priority and allocate resources for each service according to the priority; if there are still remaining resources after the real-time service is allocated, the non-real-time service is calculated according to the transmission rate under the current channel, the data waiting time and the accumulation of the buffer area. The scheduling priority of a non-real-time service and allocate wireless resources; the scheduled service is transmitted, and before the end of the scheduling cycle, all parameters are updated to prepare for the next scheduling cycle. The invention can not only meet the requirement of low time delay of real-time services in the electric power system, but also ensure the fairness of resource allocation as far as possible, and guarantee the QoS of multiple services in the electric power system.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a scheduling method for guaranteeing multi-service QoS in a power wireless system. Background technique [0002] There are many kinds of services in electric power wireless communication, such as power distribution automation business and metering, sensor information collection, etc., and different types of services have different QoS requirements. For the meter reading business, it does not have high requirements on the delay, but due to the large number of meters, a large amount of data needs to be transmitted. Therefore, a specific scheduling scheme is required to ensure the QoS of different types of services under multi-service bearer. [0003] There are three commonly used scheduling methods, which are maximum channel capacity scheduling (Maximum C / I), round robin scheduling, and proportional fair scheduling. The maximum channel capacity scheduling is to all...

Problems solved by technology

The proportional fair scheduling algorithm uses the average data rate to represent the fairness among users, which has good long-term fairness, but cannot guarantee the short-term fairness among users, and cannot

[0004] These three scheduling algorithms do not take into account the QoS requirements of application layer services, and cannot be applied to the scheduling of services that require delay.
