Abstract

A method is performed in a network node of a mobile communication network, for determining a dropped connection to a mobile terminal. The method comprises: detecting a release of a radio bearer associated with the mobile terminal; determining whether the radio bearer is a real-time type radio bearer; when the radio bearer is a real-time type radio bearer, determining the released radio bearer to be a dropped connection when the release is classified as an involuntary release; and when the radio bearer differs from a real-time type radio bearer, determining the released radio bearer to be a dropped connection when there is remaining user data in a buffer for transfer in either direction over the released radio bearer. A corresponding network node, computer program and computer program product are also presented.
