Abstract

The invention discloses a model updating method, a model updating device and a model updating system, which are used for solving the problem of network performance reduction caused by model performance reduction in the prior art. The method comprises the steps that a first functional entity sends a model updating strategy to a second functional entity, the model updating strategy comprises updating conditions of a model of a first network element, and the model of the first network element is used for guiding parameter adjustment of the first network element; when the first functional entity receives an updating request, a process of updating the model of the first network element is executed, wherein the updating request is triggered when the second functional entity determines that the model meets the updating condition, the first functional entity can be an analysis and modeling function AMF entity, and the second functional entity can be an intelligent collaborative function APF entity or a model execution function MEF entity.

Description

technical field [0001] The present application relates to the field of information technology, and in particular to a model updating method, device and system. Background technique [0002] With the development of artificial intelligence (AI) technology, AI is more widely used in wireless networks. In the artificial intelligence network architecture, the data generated by the mobile network is analyzed based on the model generated by machine learning technology, and the mobile network is optimized based on the analysis results generated by the model to better support user services, which has become a trend in the evolution of mobile networks . [0003] During the running of the model, due to changes in the wireless network environment, the performance of the model may be degraded, making the network unable to operate normally. This requires a model update mechanism to trigger the model update in time to ensure the validity of the model. In the existing intelligent network ...
