representing the reference scheduling priority corresponding to the data service;
representing the scheduling packet correction factor;
the number of the scheduling packets represents the total number of the scheduling packets in the scheduling time length, and only 1 packet is calculated as long as the data service is scheduled no matter whether the RANK value of the user is greater than 1; and when the RLC buffer corresponding to the data service is from empty to non-empty and the first packet is just started to be scheduled, the scheduling time length and the number of the scheduling packets corresponding to the data service are both initialized to 1.
In the method provided by the embodiment of the invention, the longer the scheduling time interval of the data service or the smaller the number of the scheduling packets, the scheduling priority of the data service needs to be correspondingly improved, and the scheduling priority of the data service is adjusted by using the scheduling packet correction factors in the scheduling packet types, so that the scheduling interval is shortened, and the perceived rate is improved.
In the method provided by the embodiment of the invention, the adjustment type of each data service of the user can be determined according to the index focused by the user, the scheduling parameters corresponding to the data service are obtained according to the adjustment type of the user, the scheduling correction factors are obtained by operation according to the scheduling parameters, and besides the adjustment type of the scheduling packet, the adjustment type of the scheduling packet can also be the rate adjustment type; when the adjustment type of the data service is a rate adjustment type, a specific process of determining the rate correction factor is shown in fig. 3, and the specific contents are as follows:
s301: when the adjustment type is a rate adjustment type, acquiring the scheduling duration from empty to non-empty of an RLC buffer zone corresponding to the data service and starting scheduling of a first packet of the data service to a current transmission time interval, and the traffic of the data service scheduled in the scheduling duration;

S302: acquiring a preset target sensing rate, and calculating according to the target sensing rate, the scheduling time length and the traffic volume to acquire a rate correction factor corresponding to the data service;
in the method provided by the embodiment of the invention, the target sensing rate is preset in the base station, and the parameter configuration in the network is sent to the base station through the network parameter configuration entity, wherein the network parameter configuration entity can be a core network or other communication network equipment capable of sending network parameters to the base station; the parameter configuration can be various parameter configurations of conditions for determining the sensing rate adjustment type and the target sensing rate;
The determined sensing rate adjustment type is determined according to the index focused by the user, namely the sensing rate adjustment type is determined according to the user identification, and the target sensing rate is required to be set according to the actual network and the user requirement;
preferably, the target sensing rate may face all users in the base station, that is, all data services of the users in the base station correspond to a preset target sensing rate; for example, when the target perceived rate is 7kbps and when the base station has data service application rate correction factors to adjust the reference scheduling priority of the data service, the applied target perceived rate is 7kbps; the target perceived rate is applied to all data services of which the applied rate adjustment types in the base station correct the reference scheduling priority.
When the actual perceived rate of a user is higher than a preset target perceived rate, the target scheduling priority after the reference scheduling priority of the data service corresponding to the user is corrected is reduced; if the actual perceived rate of the user is lower than the preset target perceived rate, the target scheduling priority after the reference scheduling priority of the data service corresponding to the user is corrected is increased; the magnitude of the target scheduling priority rise and fall depends on the actual perceived rate;
Optionally, in order to reduce the influence on the central user perceived rate as much as possible, when the actual perceived rate of the user data service is higher than the target perceived rate, the target scheduling priority of the data service can be maintained as the reference scheduling priority, and when the actual perceived rate of the user data service is lower than the target perceived rate, the reference scheduling priority of the data service is corrected according to the rate adjustment type; compared with the central user, when the data service reference scheduling priority of the central user is corrected, the corrected target scheduling priority is not rapidly improved, so that the probability of the actual perception rate of the central user is reduced.
S303: acquiring a reference scheduling priority corresponding to the current data service;
the method provided by the embodiment of the invention is consistent with the content in the step S203.
S304: substituting the scheduling packet correction factors corresponding to the reference scheduling priority and the current data service into a preset second scheduling priority correction formula, and calculating to obtain the target scheduling priority;
in the method provided by the embodiment of the invention, the rate correction factor is calculated by using a target perceived rate, a scheduling time length and the traffic to obtain a corresponding rate correction factor, and the scheduling packet correction factor and a reference scheduling priority are substituted into a second scheduling priority correction formula which is preset to obtain the target scheduling priority through calculation;
The second scheduling priority correction formula is:
wherein, the liquid crystal display device comprises a liquid crystal display device,
FreqEff represents the user spectral efficiency corresponding to the data service;
representing a current historical filtering rate of the data traffic;
schTime represents the scheduling duration from empty to non-empty of the RLC buffer corresponding to the data service and starting scheduling of the first packet of the data service to the current transmission time interval;
data_scheduled represents scheduled traffic within a schTime duration;
v target representing the target perceived rate in kbps;
representing the reference scheduling priority corresponding to the data service;
representing the rate correction factor;
and when the RLC buffer corresponding to the data service starts to be scheduled from empty to non-empty and the first packet starts to be scheduled, both schTime and data_sched are initialized to 1.
In an extreme case, if there is a full-packet user at the cell edge, that is, after the data service is scheduled, data is left in the RLC buffer corresponding to the data service, and meanwhile, the modulation and coding policy (Modulation and Coding Scheme, MCS) is very low, the calculated perceived rate value is far lower than the target perceived rate value, and at this time, the user will occupy more resources, which may cause a decrease in the total throughput of the cell. For this case, if the user MCS is lower than the preset threshold, the second term in the second scheduling priority correction formula is set to 1, that is, the rate correction factor is set to 1, and the calculation method of the reference scheduling priority is maintained.
It should be noted that, the method provided by the present solution is not limited to the first scheduling priority correction formula and the second scheduling priority correction formula described above, and other formulas may be used to calculate to obtain the target scheduling priority; the invention is not limited to the fair proportion scheduling algorithm applied in the scheduling of the data service, and can be applied to other data service scheduling methods; the method provided by the invention is suitable for all communication systems which need to be evaluated through user perception rate indexes, including but not limited to 4G/5G LTE communication systems.
