Benefits of technology

[0005]It is an object of embodiments herein to determine a dropped connection such that it better reflects the user experience of drop, regardless whether the connection relates to best-effort traffic or to a real-time service such as voice.

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.

Embodiment Construction

[0038]The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout the description.

[0039]FIG. 1 is a schematic diagram illustrating a mobile communication network 5 where embodiments presented herein can be applied. The mobile communications network 5 comprises a core network 3 and one or more network nodes 1, here in the form of evolved Node Bs 1, also known as e-Node Bs or eNBs. The network nodes 1 provide radio connectivity to a plurality of mobile terminals 2. The term mobile terminal is also known as user equ...

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...
