Abstract: Techniques for detection of abnormal network function service usage in a communication network are disclosed. For example, a method comprises obtaining, at a first network entity, one or more service requests previously received by a second network entity for a service which the second network entity is configured to provide in a communication network. The method further comprises obtaining, at the first network entity, an analysis of the one or more service requests previously received by the second network entity for the service. The method further comprises obtaining, at the first network entity, an expected service usage for the service from the analysis of the one or more service requests. The method may then compare incoming service requests to the expected service usage to detect a given condition, e.g., an abnormal condition, so that at least one action can be taken.
