Claim:
1. A method for optimizing a mobility robustness of a mobile radio communication network with respect to moving user equipments being supposed to be handed over within the mobile radio communication network from a source cell to a target cell, the method comprising detecting, by a base station based on reporting information from the user equipments, handover problems which have been occurred within a predefined time interval, classifying the detected handover problems into a first category, into a second category and into a third category, determining at least one information being related to at least one of the detected handover problems, wherein the at least one information represents a refinement of at least one of the three categories or wherein the at least one information represents a further category, counting a first number of handover problems which have been classified into the first category, a second number of handover problems which have been classified into the second category and a third number of handover problems which have been classified into the third category, reporting a key performance indicator message to a central unit of the mobile radio communication network, wherein the key performance indicator message is indicative for the first number, the second number and the third number and for the determined at least one information, and adapting, based on the reported key performance indicator message, a value of at least one mobility related network configuration parameter of the mobile radio communication network such that the mobility robustness of the mobile radio communication network is optimized.
