In network operations, it is important to precisely and quickly know the effects on services when network problems occur. However, traffic monitoring, such as measuring the amount of transferred packets, is not sufficient to detect service abnormalities. In this paper, we propose a detection scheme for service abnormalities based on users attempting to reconnect. They are measured by the specific signaling in mobile core networks. We implement and evaluate the proposed scheme in a commercial mobile network. With the results of the evaluation, we prove the usefulness of the proposed scheme.
