The network resource scheduling method provided by the embodiment of the application can be applied to a network resource scheduling system at a base station side, after classifying services, obtaining a corresponding monitoring result by monitoring the service perception attribute of a certain service, comparing the monitoring result with a preset service perception attribute threshold value, adjusting the preset service scheduling weight factor of the service which does not meet the preset service perception attribute threshold value to obtain a new service scheduling weight factor, and finally performing network resource scheduling according to the new service scheduling weight factor and a scheduling request of a terminal.
An embodiment of the present application provides a network resource scheduling method, which is applied to a network resource scheduling system, and as shown in fig. 1, the method may include S101 to S104:
s101, identifying the service type in the network resource scheduling request.
Before identifying the service category in the network resource scheduling request, a plurality of services in the network need to be classified according to the traffic characteristics, the service quality level, the server identifier and the like. Only if two services belong to the same class in the three dimensions of flow characteristics, quality of service level, and server identification. It should be noted that the classification basis is only an exemplary description in the embodiments of the present application, and other classification basis may also be included, and the present application is not limited.
The flow characteristics comprise any one of message size, transmission flow size and uplink and downlink message number proportion; the service quality features include: any one of data packet delay, data packet loss rate and service priority; the service server identification comprises: a domain name server name and a domain name feature value. The traffic characteristics and the service quality classes are divided into different class intervals, for example, when the traffic characteristics are expressed by the ratio of the number of uplink messages to the number of downlink messages, the traffic characteristics can be divided into ten classes with 10% as granularity. If the traffic characteristics and the service quality grade of the service are the same and the service server identification is consistent, the service belongs to one category.
All the services of the current network are divided according to the classification bases, and after a system receives a network resource scheduling request initiated by a terminal, the service type in the network resource scheduling request is firstly identified, for example, the service type comprises video downloading, live broadcasting, games, video or voice call and the like.
S102, obtaining a monitoring result corresponding to the service perception attribute of the service type.
The service class in the network resource scheduling request is obtained through step S101, and a monitoring result corresponding to the service perception attribute of the service class is further obtained according to the service class. The service perception attribute is used for representing the quality of user service experience perception, and specifically includes any one of a service pause proportion, a service perception delay and an experience perception rate. And acquiring a monitoring result corresponding to the service perception attribute of the service category, for example, the service is a video call, acquiring a specific numerical value of the service perception delay in the call process, wherein the specific numerical value is the monitoring result, and acquiring how the user experiences when using the service through the service perception delay.
S103, if the monitoring result does not meet the preset service perception attribute threshold value, adjusting the preset service scheduling weight factor and determining a new service scheduling weight factor.
And setting a preset service perception attribute threshold value and a preset service scheduling weight factor according to the historical service perception attributes of all service classes. The system acquires the service E monitored by the base station sideiHistorical service perception property P ofiPresetting service EiService aware attribute threshold T ofEi＝αin*PiWherein α isinRepresentative service EiAt the service awareness property PiThe lower threshold value self-regulation factor can be modified by modifying the threshold value self-regulation factor alpha according to the requirementinAdjusting the required service perception attribute threshold value TEiSize. At the same time, according to the service EiHistorical service perception property P ofiPresetting a traffic scheduling weight factor WiThe resource scheduling weight factor distribution result is Yi(n)。
After the specific value of the monitoring result is obtained in step S102, the specific value is compared with a preset service perception attribute threshold TEiComparing, when the service perception attribute is a service morton proportion or time delay when the service perception attribute is service perception, the larger the value of the monitoring result is, the worse the service experience is, therefore, if the monitoring result is larger than a preset service perception attribute threshold value TEiThen, the preset service scheduling weight factor W is adjusted by polling iteration through adjusting the step length and the directioniDetermining a new service scheduling weight factor; when the service perception attribute is experience perception rate, the larger the value of the monitoring result is, the better the service experience is, so that if the monitoring result is smaller than a preset service perception attribute threshold value TEiThen, the preset service scheduling weight factor W is adjusted by polling iteration through adjusting the step length and the directioniAnd determines a new traffic scheduling weight factor. Increasing or decreasing the service distribution weight, and performing iterative optimization until the value of the monitoring result meets the preset service perception attribute threshold value TEiIn particular, if the monitoring result of the service class satisfies the preset service perception attribute threshold value TEiThe original preset service scheduling weight factor is the new service scheduling weight factor.
For example, the specific value of the service awareness delay in the process of acquiring the video call is 0.05ms, and the preset service awareness attribute threshold T of the video call service is obtainedEiAnd if the service experience is not good, the preset service scheduling weight factor of the service needs to be adjusted, the distribution weight of the service is increased by continuously adjusting the step length and the direction, a new service scheduling weight factor is determined, and the specific value of the service perception delay is known not to exceed 0.01 ms.
And S104, scheduling the network resources according to the new service scheduling weight factor.
After determining the new service scheduling weight factor through step S103, when receiving the network resource scheduling request initiated by the terminal again, first determining whether resource scheduling is required according to the current operation state of the service type, for example, when the service type initiating the scheduling request is the network resource occupancy rate, if the network resource occupancy rate is greater than or equal to a preset threshold value, then network resource scheduling is not required, and if the network resource occupancy rate is less than the preset threshold value, then network resource scheduling is performed according to the new service scheduling weight factor corresponding to the service type.
According to the network resource scheduling method and device, the corresponding monitoring result is obtained by monitoring the service perception attribute of a certain service, the monitoring result is compared with the preset service perception attribute threshold value, the preset service scheduling weight factor of the service which does not meet the preset service perception attribute threshold value is adjusted to obtain a new service scheduling weight factor, and finally network resource scheduling is carried out according to the new service scheduling weight factor. The method and the device can determine a new service scheduling weight factor aiming at different service requirements, allocate network resources to the service in advance, and effectively improve the rationality of resource allocation.
