Resource scheduling method and device based on service qualities

Abstract

The invention provides a resource scheduling method and a device based on service qualities. The method includes that a scheduling degree factor container is configured aimed at user equipment (UE) loads; scheduling degree factors are added in the corresponding scheduling degree factor container according to a minimum bit rate corresponding to the UE loads; scheduling priority parameters are determined according to numbers of scheduling degree factors in the scheduling degree factor container; when the delay of the UE loads is smaller than or equal to a delay threshold, the scheduling priority parameters are updated according to the delay of the UE loads and numbers of the scheduling degree factors in the scheduling degree factor container and UE resources are scheduled according to the updated scheduling priority parameters; and when the UE is scheduled, the scheduling degree factors corresponding to scheduled resource numbers are deducted from the scheduling degree factor container. According to the resource scheduling method and the device, the consumption of hollow resources can be reduced, and the user business perceptibility is improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a resource scheduling method and device based on quality of service. Background technique [0002] In an LTE (Long Term Evolution, Long Term Evolution) system, a QoS (Quality of Service, Quality of Service) mechanism is used to guarantee the quality of service of the UE. Each EPS (Evolved Packet System) bearer has corresponding QoS parameters; according to different QoS parameters, EPS bearers can be divided into GBR (Guaranteed Bit Rate) and Non-GBR (non-guaranteed bit rate) rate) into two categories. [0003] QoS parameters can specifically include QCI (QoS Type Identifier, QoS Class Identifier), ARP (Allocation and Retention Priority), GBR / MBR (Maximum Bit Rate), AMBR (Maximum Aggregation Bit Rate, Aggregate Maximum Bit Rate), etc. Among them, QCI specifically includes priority (Priority), packet delay (PDB, Packet Delay Budget), and PELR (Packe...

Problems solved by technology

However, due to the lack of fairness considerations, a certain UE may not be scheduled for a long time;

[0009] PF (Proportional Fair) method: The proportional fair method sorts UEs according to UE channel quality, UE priority, service level, throughput forgetting factor, etc., which can increase the throughput of the system under the premise of ensuring relative fairness However, because there are many factors to be considered, and some of these factors change in real time, the implementation is complicated

[0010] In the above three scheduling methods, as long as the UE has data and meets the scheduling priority conditions, it will be scheduled. Even a small data packet will cause the scheduling of the UE, which causes each TTI (Transmission Time Interval, Transmission Time Interval) to schedule a large number of UEs; in the LTE system, data transmission requires uplink and downlink MCS (Resource Scheduling Information, Modulation Coding Scheme) needs to be carried by PDCCH (physical downlink control channel, physical downlink control channel), and at the same time Feedback of data packets and channel quality also requires channels such as PHICH and PUCCH to carry; channels such as PDCCH, PHICH (Physical HARQ Indicator Channel, Physical Hybrid-ARQ Indicator Channel) and PUCCH (Physical Uplink Control Channel, Physical uplink control channel) are all Air interface resources, so the scheduling method of the prior art consumes a lot of air interface resources
