Abstract

To provide a technique which increases the number of options relating to provision of a model to three or more.SOLUTION: A core network for a mobile communication network comprises: storage means for storing a plurality of models being generated based on learning data and used for the same application but at different levels, the level of the model indicating a degree of the amount of information relating to learning data included in the model; determination means for determining, in response to receiving a message requesting a first model for a first application from a consumer node, whether or not the first model can be provided to the consumer node and, in a case where the first model can be provided to the consumer node, a level of the first model that can be provided to the consumer node; and notification means for notifying, in a case where it is determined that a first learning model at a first level can be provided to the consumer node, the consumer node of information identifying the first model of the first level.SELECTED DRAWING: Figure 5
