Network data analytics function accuracy enhancement
Systems, methods, apparatuses, and computer program products for network data analytics function (NWDAF) accuracy enhancement. A method may include selecting a network function that can provide accuracy information. The method may also include sending a request to the network function for one or more accuracy reports for one or more analytics predictions. The method may further include receiving the one or more accuracy reports from the network function. In addition, the method may include managing the one or more analytics predictions based on the one or more accuracy reports.
1 . An apparatus for a mobile telecommunications system, the apparatus comprising:
at least one processor; and
at least one memory storing instructions of a network function of the mobile telecommunications system, wherein the instructions, when executed by the at least one processor, cause the apparatus to perform operations, the operations comprising:
selecting a Network Data Analytics Function (NWDAF) of the telecommunications system that configured to provide analytics predictions and accuracy information for the analytics predictions;
sending, to the NWDAF, a request for one or more accuracy reports, wherein respective accuracy reports of the one or more accuracy reports comprise accuracy information indicating an accuracy of a prior analytics prediction generated by the NWDAF related to an actual outcome;
receiving, from the NWDAF, the one or more accuracy reports; and
managing a subscription for analytics predictions based on the one or more accuracy reports.
2 . The apparatus according to claim 1 , wherein the managing comprises managing use of analytics predictions.
3 . The apparatus according to claim 1 , wherein the operations further comprise:
sending an instruction to the NWDAF on how to handle the subscription.
4 . The apparatus according to claim 1 , wherein the request for the one or more accuracy reports comprises instructions specifying one or more conditions for the NWDAF to terminate the subscription for analytics predictions and stop sending the one or more accuracy reports, or to transfer the subscription for analytics predictions and to transfer the request for the one or more accuracy reports to another NWDAF.
5 . The apparatus according to claim 4 , wherein the one or more conditions comprise:
a number or a percentage of the one or more accuracy reports is above a threshold and the one or more accuracy reports comprise accuracy information indicating an accuracy that is below a threshold.
6 . The apparatus according to claim 1 , wherein the request to the NWDAF for the one or more accuracy reports further comprises a request for analytics predictions.
7 . The apparatus according to claim 1 , wherein the operations further comprise:
sending processing and filtering instructions to the NWDAF to combine or filter the one or more accuracy reports.
8 . The apparatus according to claim 1 , wherein the operations further comprise:
sending processing and filtering instructions to the NWDAF to control a frequency of sending the one or more accuracy reports.
9 . The apparatus according to claim 1 , wherein at least one of the one or more accuracy reports is an aggregated report comprising at least one of aggregated accuracy information of a plurality of subscriptions, and aggregated accuracy information based on a plurality of comparisons between prior predictions and an actual outcome related to a single subscription.
10 . The apparatus according to claim 1 , wherein the operations further comprise:
sending instructions to the NWDAF to stop sending analytics predictions and to terminate the subscription for analytics predictions after receiving a last accuracy report has been received, or to transfer the subscription for analytics predictions and to transfer the request for the one or more accuracy reports to another NWDAF.
11 . An apparatus for a mobile telecommunications system, the apparatus comprising:
at least one processor; and
at least one memory storing instructions of a Network Data Analytics Function (NWDAF) of the mobile telecommunications system, wherein the instructions, when executed by the at least one processor, cause the apparatus to perform operations, the operations comprising:
receiving, from an analytics consumer, a request for one or more accuracy reports;
obtaining, in response to the request, accuracy data indicating an accuracy of a prior analytics prediction generated by the NWDAF relative to actual outcome;
generating the one or more accuracy reports based on the accuracy data; and
sending, to the analytics consumer, the one or more accuracy reports based on the accuracy data.
12 . The apparatus of claim 11 , further comprising:
managing a subscription for analytics predictions based on the one or more accuracy reports.
13 . The apparatus according to claim 12 , wherein the managing comprises managing use of the analytics predictions.
14 . The apparatus according to claim 12 , wherein the subscription for the analytics predictions is comprised in the request for the one or more accuracy reports.
15 . The apparatus, according to claim 12 , wherein the request for the one or more accuracy reports comprises instructions specifying one or more conditions to terminate the subscription for the analytics predictions and stop sending accuracy reports, or to transfer the subscription for the analytics predictions and to transfer the request for the one or more accuracy reports to another NWDAF.
16 . The apparatus according to claim 15 , wherein the one or more conditions comprise:
a number or a percentage of the one or more accuracy reports is above a threshold and the one or more accuracy reports comprise accuracy information indicating an accuracy that is below a threshold.
17 . The apparatus according to claim 12 , wherein the operation further comprise:
receiving instructions to stop sending analytics predictions and to terminate the subscription for the analytics predictions after a last accuracy report has been received, or to transfer the subscription for the analytics predictions and to transfer the request for the one or more accuracy reports to another NWDAF.
18 . The apparatus according to claim 11 , wherein the operation further comprise:
storing accuracy information based on the one or more accuracy reports in a profile of the NWDAF.
19 . The apparatus according to claim 11 , wherein the operations further comprise:
receiving processing and filtering instructions from the analytics consumer to combine or filter the one or more accuracy reports.
20 . The apparatus according to claim 11 , wherein the operations further comprise:
controlling a frequency of the one or more accuracy reports via a separate filtering or reporting instruction received in the request.
21 . The apparatus according to claim 11 , wherein the operations further comprise:
collecting data of actual outcomes related to analytics predictions; and
performing, with the collected data and predictions, self-improvement functions and machine learning operations.
