Abstract: There are provided measures for enabling/realizing more efficient radio link problem handling in a mobile communication system. Such measures exemplarily comprise detecting a radio problem of a radio link carrying a network connection of a communication device, and initiating a recovery procedure for recovering the connection on said radio link and a re-establishment procedure for re-establishing the connection on an alternative radio link, upon detection of the radio link problem, before a radio link failure of said radio link is declared.

Abstract: There is provided a method comprising: determining an information on an inter-symbol interference between signals on a same frequency resource and a same time resource from one or more first cells and one or more second cells, wherein an active set of the apparatus comprises at least the one or more second cells, the inter-symbol interference is an estimated inter-symbol interference if at least one of the one or more first cells is not in the active set, and the inter-symbol interference is a measured inter-symbol interference if the active set consists of the one or more first cells and the one or more second cells; and deciding whether or not to inform a network comprising the one or more first cells and the one or more second cells on the information on the inter-symbol interference.

Abstract: A method may include receiving a request for conditional handover from a source node. The method may also include sending a conditional handover request acknowledgment message in response to the request. The method may further include sending a conditional handover cancellation message to a source node. The conditional cancellation message may include a genuine cancellation or a modification-related cancellation. Further, the method may include receiving a response message from the source node in response to the conditional handover cancellation message. In addition, the method may include deciding to keep or release user equipment context based on the response message.

Abstract: According to an example aspect of the present invention, there is provided a method comprising, determining, by a source base station, a first target cell and a second target cell for a handover of a user equipment, wherein the first target cell and the second target cell are cells of the same target base station, setting, by the source base station, an identifier of a first handover preparation procedure and an identifier of a second handover preparation procedure, wherein the identifier of the first handover preparation procedure is different compared to the identifier of the second handover preparation procedure, initializing, by the source base station, the first handover preparation procedure to the first target cell and the second handover preparation procedure to the second target cell and binding, by the source base station, the identifier of the first handover preparation procedure and the identifier of the second handover preparation procedure.

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. The first counter and/or the second counter of the neighbor relation information concerning the determined first and second candidate handover target cells is updated.
