Time domain group scheduling method on basis of two-dimensional priority level

Abstract

The invention discloses a time domain group scheduling method on the basis of a two-dimensional priority level. The method comprises the following steps of according to the service characteristics and QoS (quality of service) requirements of different services, calculating the two-dimensional priority level of each service; comparing the urgent coefficient of each service, and sequentially arranging the priority level of each service from high urgent coefficient to low urgent coefficient; comparing the first-dimensional priority levels in the two-dimensional priority levels of the services with the same urgent coefficient, and sequentially arranging the priority level of each service according to the sequence of the first-dimensional priority levels; and comparing the two-dimensional priority levels of the services with the same first-dimensional priority level, and sequentially arranging the priority level of each service from high two-dimensional priority level to low two-dimensional priority level, wherein the calculation of time domain priority level is finished, the sequence of the priority levels is the final time domain group scheduling result. The variety, the abruptness and the multiple requirements of a service are comprehensively considered, so that the time domain group scheduling method which is applied to the current wireless communication system is obtained, and the optimization of time domain group scheduling is realized.

Description

technical field [0001] The invention belongs to the field of wireless communication, and relates to a time-domain grouping scheduling method, in particular to a two-dimensional priority-based time-domain grouping scheduling method. Background technique [0002] With the development of wireless communication, more and more types of services appear continuously. The user's business needs have expanded from pure voice services to various multimedia services such as video telephony, real-time video, interactive web browsing, and database retrieval. However, the traditional way of classifying user services into real-time services and non-real-time services is obviously no longer applicable to the status quo of the current wireless communication system. In addition, the service requirements of mobile users are no longer limited to the "single-user-single-service" model. At the same time, a user may simultaneously need to provide multiple services with greatly different QoS perfor...

Problems solved by technology

However, in view of the status quo of the current wireless communication system, the time-domain packet scheduling based on these two methods has shortcomings.

[0004] (1) User-based time-domain group scheduling, which considers all business data of a user uniformly, adopts the same priority calculation method for user data grouping, and ignores the differences in business characteristics of different services. Therefore, it cannot achieve a good user perception

[0005] (2) Service-based time-domain packet scheduling often simply divides services into real-time and non-real-time, or simply considers that a user has only one service requirement at a certain moment, or considers that the priority of some services is absolutely higher than that of Priority of other services, without considering the diversity of services, multiple needs of users, and sudden demands of services, so it cannot be well adapted to the current wireless communication system
