Embodiment Construction

[0107] The preferred embodiments represent means for identifying and correcting undesired handover behavior eg in E-UTRAN. The solution takes one or more measurements of the radio conditions between the mobile terminal and the target and source cells to achieve a successful handover. Measurements are taken at the end of the handover execution and optionally at the trigger point and optionally at an interval after the handover. Several measurements (for a particular handover, eg cell A to cell B) may be collected at one point to facilitate analysis. Due to the optimization procedure on the analyzed results, the handover parameters controlling a particular handover can be changed. The method aims to proactively adjust the switching parameters to the optimum point. This can, for example, eliminate handovers that fail in a premature manner. A solution to the problem may thus include the following steps:

[0108] 1. Capture of measurement results on successful handover

Abstract

The invention provides a method for handover problem identification in a mobile telecommunications system. The system includes at least a first radio base station, a second radio base station and a mobile terminal able to communicate with the base stations, the mobile terminal is adapted to do a handover from the first base station to the second base station. The method includes the steps of: taking at least one measure of a link quality between the terminal and any of the stations, evaluating any measure of a link quality in regard of the handover problem identification. The invention is characterized in that in the step of taking the at least one measure, at least one measure of a link quality is taken at an end of a successful handover execution of the mobile terminal from the first base station to the second base station. The invention also provides a mobile terminal, a radio base station and a management entity for the mobile telecommunication.

Description

technical field [0001] The invention relates to a method for handover problem identification in a mobile telecommunication system. Furthermore, the invention relates to a mobile terminal for a mobile telecommunication system, a radio base station for a mobile telecommunication system and a management entity for a mobile telecommunication system. Background technique [0002] The context of the background art (and the present invention) is a cellular wireless network system. The system may comprise at least a first radio base station and a second radio base station capable of communicating with mobile terminals. Furthermore, the mobile terminal is adapted to be handed over from the first base station to the second base station, meaning that the mobile terminal can switch communications from the first base station to the second base station as the communications traverse the network. [0003] Depending on the type of cellular network system involved, the entities in this sys...
