Abstract: A second handover of a user equipment from a cell B to a cell C of a cellular communications network is successfully completed, wherein a successful completion of a first handover of the user equipment from a cell A of the cellular communications network to the cell B has immediately preceded the second handover. The second handover is determined as being a rapid handover at the cell B and/or the cell C based on a detection that the second handover of the user equipment has been initiated from the cell B to the cell C within a configurable period of time since the successful completion of the first handover, and the rapid handover is reported to the cell A.

Abstract: There is provided a method and an apparatus for determining an adjustment of a tilt angle (?1, ?2) for a beam emitted from an antenna (130) of a base station (100) which is serving a vertically sectorized cell (150) of a cellular radio telecommunication network. The method comprises (a) configuring user equipments (162, 164) being located in the vertically sectorized cell (150) with dedicated measurements, (b) collecting the dedicated measurements for a specific time interval, (c) obtaining a spatial user equipment distribution among a first sector (152) of the cell (150) and a second sector (154) of the cell (150) based on the collected dedicated measurements, (d) ascertaining an optimized spatial overlap region between the first sector (152) and the second sector (154) based on the obtained spatial user equipment distribution, and (e) determining the adjustment of the tilt angle (?1, ?2) based on the ascertained optimized spatial overlap region.

Abstract: Methods, apparatus and computer program products are disclosed for enhancing mobility robustness optimization in self optimizing networks. Neighbor relation information indicating relations between a handover source cell and candidate handover target cell(s), each including a first counter indicating events of an unsuccessful handover of a user equipment from the handover source cell to one candidate handover target cell, and a second counter indicating events of connection re-establishment attempt of the user equipment to the candidate handover target cell after an unsuccessful handover to another cell. A first candidate handover target cell to which handover of the user equipment was unsuccessful and a second candidate handover target cell to which the user equipment has re-established a connection, out of the candidate handover target cells, are determined.

Abstract: Methods, apparatuses and computer program products are provided, wherein an indication is provided to a second network entity from a first network entity to monitor a quality of service provided to a user equipment handed over from the first network entity to the second network entity. The second network entity monitors the quality of service provided to the user equipment and generates a corresponding indication. The indication of the quality of service provided to the user equipment by the second network entity is then provided by the second network entity to the first network entity. Based on the received indication of the quality of service, a determination as to whether a handover was necessary is made by the first network entity.

Abstract: There are provided measures for detection and inhibition of multiple consecutive inter-RAT ping-pong handovers (also called handover bounces). Such measures exemplarily include detecting multiple consecutive ping-pong handovers of a communication endpoint between two radio access technologies, wherein a ping-pong handover includes a handover from one of said two radio access technologies to the other of said two radio access technologies and a handover from the other of said two radio access technologies to the one of said two radio access technologies, and causing immediate inhibition of certain handovers of said communication endpoint.

Abstract: Apparatuses and methods are provided by which a user equipment receives information enabling handover and/or apparatus type identification related to a handover, and stores the information enabling handover and/or apparatus type identification. In case of a connection failure, the stored information enabling handover and/or apparatus type identification may later be used to evaluate the cause for the connection failure.
