Method, network node, computer program and computer program product for determining a dropped connection

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 374,891, filed Jan. 26, 2012, which is a national stage of International Application No. PCT / SE2012 / 050080, filed Jan. 26, 2012, which are hereby incorporated by reference.TECHNICAL FIELD[0002]The invention relates to mobile communication networks and in particular to determining a dropped connection in a mobile communication network.BACKGROUND[0003]In mobile communication networks, dropped connections are undesired and can cause significant frustration for end users. It is thus desired to detect and measure dropped connections as part of a quality measurement or key performance indicator (KPI). In modern mobile communication networks such as Long Term Evolution (LTE) of the 3rd Generation Partnership Project (3GPP), the measurement for drop rate is calculated using dropped connections, which is dropped bearers when there is remaining data in the buffer, and a sessi...

AI Technical Summary

Benefits of technology

The technical effect of this patent is to provide a more accurate measurement of dropped connections, regardless of the type of traffic or service. Specifically, the patent proposes a method for distinguishing between real-time and non-real-time radio bearers, and measuring the session duration accordingly. This allows for a more customized measurement of drop rates for different types of services. In summary, the patent proposes a way to better understand and manage dropped connections for real-time and non-real-time services.

Problems solved by technology

In this way, for real-time type bearers, any released bearer during the session is considered a dropped connection, as it most likely causes a service disruption for the end-user.
