Problems solved by technology

[0005] Considering that the business data scheduling process in the related art cannot take into account the quality of service and other factors, the scheduling process will reduce the system performance, the service quality of the business, and the lack of fairness in the scheduling process itself, and the present invention is proposed. For this reason, The main purpose of the present invention is to provide a real-time service scheduling method and device to solve the above problems

[0028] Functional Overview

[0029] IEEE 802.16 mainly includes three real-time data transmission services: Unsolicited Grant Service (UGS for short), Extended Real-Time Variable-Rate (ERTVR for short), and Real-Time Variable-Rate (ERTVR for short). Real-Time Variable-Rate, referred to as RTVR), these three services can provide the minimum reserved rate and maximum delay QoS guarantee, UGS and ERTVR can also provide delay jitter guarantee. Moreover, these three real-time services also support service priority parameters, and service flows with low priority may lag behind services with high priority.

[0030] Currently, the scheduling of WiMAX real-time services needs to meet the following requirements: 1. Requirements for guaranteed time delay; 2. Requirements for guaranteed minimum rate; 3. Guarantee for fairness and system throughput; 4. The realization of the scheduling method is relatively simple. Based on this, the present invention proposes a real-time service schedulin...

Abstract

The invention discloses a dispatching method of real-time business and a device thereof. The method comprises the step of dispatching business data in at least one queue to be dispatched by a first dispatching method and a second dispatching method, wherein, the first dispatching method is used for dispatching part of the business data in at least one queue to be dispatched; and the second dispatching method is used for dispatching the other part of the business data in at least one queue to be dispatched. By adopting the technical scheme of the invention, a plurality of the dispatching methods are introduced to dispatch the business data in the dispatching queue so as to complete data dispatching, ensure time delay and long-term fairness and flexibly achieve updating dispatching strategies, thus being capable of carrying out multi-objective dispatching, effectively improving business service quality, and increasing user experiences on the premise of guaranteeing dispatching efficiency.

Description

technical field [0001] The present invention relates to the communication field, in particular to a real-time service scheduling method and device. Background technique [0002] With the development of broadband wireless access systems, the requirements for resource allocation are getting higher and higher. In the resource allocation process, a base station (Base Station, BS for short) allocates resources to a mobile station (Mobile Station, MS for short) according to a certain strategy, and the MS uses the resources allocated by the BS. [0003] In a wireless environment, when packet scheduling is performed, the relatively simple scheduling method currently proposed cannot fully consider the following aspects: 1. The variability of the wireless link. During the data transmission process, various interferences, fading, and changes in the position of the MS will cause changes in the transmission link, which will affect the data transmission situation. 2. Fairness. Its defi...
