20130295915 | Network Nodes and Methods Configured for Updating Neighbor Cell Information in a Radio Communications System Comprising at Least One Radio Access Technology Network - The present invention refers to network nodes and methods being configured for updating neighbor cell information in a radio communications system including at least one Radio Access Technology network. The radio communications system includes a mobile terminal, a first network node controlling a first cell, a second network node controlling a second cell, the first network node broadcasting a first neighbor cell list, and the second network node broadcasting a second neighbor cell list. The method includes the steps of receiving, by the second network node from the mobile terminal, an indicator, with the indicator indicating a missing neighbor cell relation entry in the first neighbor cell list, the neighbor cell relation entry representing a neighbor cell relation between the first cell and the second cell; and sending, from the second network node to the first network node, a cell identifier, the cell identifier uniquely identifying the second cell, and first cell-specific information technically characterizing the second cell, the first cell-specific information permitting updating the first neighbor cell list, with the missing neighbor cell relation entry. | 11-07-2013 |
20140200005 | User Equipment Short Stay Report - 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. | 07-17-2014 |
20140206360 | Optimizing a Handover Behavior of a Mobile Radio Communication Network Based on an Extended Report Message Comprising Information about a Performed Handover - A method includes optimizing a handover behavior of a mobile radio communication network including at least a first base station and a second base station. The method includes (a) performing a handover of a UE from the first base station to the second base station; (b) adding an information element representing a property of the UE to a report message including information about the performed handover; (c) forwarding the report message from the second base station to the first base station; and (d) optimizing the handover behavior of the mobile radio communication network based on the added information element. Further, it is described a base station which is configured for carrying out the described handover behavior optimization method. | 07-24-2014 |
20140235245 | Optimizing a Handover Behavior of a Mobile Radio Communication Network Based on an Extended Record Being Associated with a User Equipment - It is described a method for optimizing a handover behavior of a mobile radio communication network including at least a first base station and a second base station. The method includes (a) performing a handover of a user equipment from the first base station to the second base station, (b) adding an information element representing a property of the radio link between the user equipment and the first base station to a data record being associated with the user equipment, (c) transferring the data record from the first base station to the second base station and (d) optimizing the handover behavior of the mobile radio communication network based on the added information element. It is further described a first base station and a second base station, which in conjunction which each other, are configured for carrying out the described handover behavior optimization method. | 08-21-2014 |
20150016365 | Carrier Aggregation Optimization - The present invention provides a method, apparatus and a computer program product for carrier aggregation optimization.
