Validity indication as a function of confidence level
Systems, methods, apparatuses, and computer program products for indicating validity as a function of confidence level. A requesting network entity may receive a prediction request from a requesting network entity that comprises timing information indicating when a prediction needs to be obtained. The receiving entity may then transmit a response to the requesting network entity associated with the requested prediction.
1 . A first radio access network (RAN) node comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the first RAN node at least to:
receive a prediction request from a requesting second RAN node comprising timing information indicating when a prediction needs to be obtained, wherein the prediction request comprises a required confidence that the prediction must satisfy; and
determine whether the prediction request is critical or non-critical based on the critical indication,
wherein the at least one memory and the instructions, when executed by the at least one processor, further cause the first RAN node at least to:
calculate the requested prediction; and
determine whether the calculated prediction satisfies the required confidence;
in response to determining that the calculated prediction satisfies the required confidence, transmit a response to the second RAN node, the response comprises an inference report comprising the calculated prediction;
in response to determining that the calculated prediction does not satisfy the required confidence:
if the prediction request is determined to be non-critical, transmit a response to the second RAN node, the response indicating a failure to calculate a prediction which satisfied the required confidence; and
if the prediction request is determined to be critical, take further actions to obtain a prediction matching the required confidence, and transmit a response to the second RAN node, the response comprising the prediction which satisfies the required confidence.
2 . The first RAN node of claim 1 , wherein the at least one memory and the instructions, when executed by the at least one processor, further cause the first RAN node at least to:
provide a prediction at an earlier point in the future in order to meet the prediction requirements in terms of the required confidence.
3 . The first RAN node of claim 1 , wherein the timing information corresponds to a timing instance, an interval of time indicated by two time instances, and a time instance and a time duration.
4 . The first RAN node of claim 1 , wherein the prediction request indicates using a soft timing indication that the prediction is flexible to be provided at a different time instant.
5 . The first RAN node of claim 1 , wherein, in response to determining that the calculated prediction does not satisfy the confidence or reliability, at least:
discard the calculated prediction;
store the calculated prediction; and
report the calculated prediction to an operations, administration, and maintenance entity.
6 . The first RAN node of claim 1 , wherein the prediction request comprises an indication of the further actions which the first RAN node should take in response to determining that the calculated prediction does not satisfy the required confidence and if the prediction request is to be critical,
wherein the further actions comprise at least:
retraining a machine learning model for calculating the prediction; and
calculating a prediction which satisfies the confidence requirement for a time different to that indicated by the timing information.
7 . A method at a first radio access network (RAN) node, the method comprising:
receiving a prediction request from a requesting second RAN node comprising timing information indicating when a prediction needs to be obtained, wherein the prediction request comprises a required confidence that the prediction must satisfy; and
determining whether the prediction request is critical or non-critical based on the critical indication, calculating the requested prediction; and
determining whether the calculated prediction satisfies the required confidence;
in response to determining that the calculated prediction satisfies the required confidence, transmitting a response to the second RAN node, the response comprising an inference report comprising the calculated prediction;
in response to determining that the calculated prediction does not satisfy the required confidence:
if the prediction request is determined to be non-critical, transmit a response to the second RAN node, the response indicating a failure to calculate a prediction which satisfied the required confidence; and
if the prediction request is determined to be critical, take further actions to obtain a prediction matching the required confidence, and transmit a response to the second RAN node, the response comprising the prediction which satisfies the required confidence.
