摘要： For each of a plurality of wireless devices, signal strength measurements performed by the wireless device are collected. The signal strength measurements are collected with respect to a plurality of cells of the wireless communication network. Further, based on the signal strength measurements, a plurality of zones of the wireless communication network is determined. Each zone indicates a position of the wireless device with respect to the cells when performing a respective one of the signal strength measurements. Further, for each of the wireless devices, a respective trajectory is determined from a sequence of the zones passed by the wireless device. Further, performance data related to the wireless devices are collected, and the performance data are filtered based on the trajectories.

摘要： A technique for determining a list of neighbouring radio resources from signal strength measurements taken by mobile terminals is presented. Two or more signal strength measurements taken by the same mobile terminal at substantially the same time are grouped to a data set that associates, for each of two or more different radio resources of a given radio resource type, a measured signal strength with an identifier of the measured radio resource. An apparatus implementation of the technique presented herein is configured to analyze, using a similarity metric, similarity of a plurality of data sets. The apparatus is further configured to cluster the data sets, or information derived therefrom, based on data sets similarity so as to obtain multiple clusters representative of different radio locations and to determine, from each cluster, a radio resource set that defines a list of neighbouring radio resources for the radio location represented by that cluster. technique for determining neighbouring radio resources based on signal strength measurements

摘要： A computer-implemented method (1400) performed in a radio access network (1510) for secondary carrier prediction is provided. The method includes obtaining (1402) an uplink channel impulse response based on a reference signal transmitted by a user equipment (UE) (104) over a primary carrier link to a serving network node (102) in a primary cell (102) currently serving the UE (104). The method includes extracting (1404) one or more features from the uplink channel impulse response. The method includes predicting (1406) an existence or non-existence of a secondary carrier link between the UE (104) and a target network node in a secondary cell (106) based on the extracted one or more features. The method includes determining (1408) whether to perform a handover procedure of the UE (104) from the serving network node in the primary cell (102) to the target network node in the secondary network cell (106) based on the predicting.

摘要： A computer implemented method (200) is disclosed for managing Conditional Handover of a UE in a cellular communication network. The method comprises receiving a report of radio resource measurements performed by a UE (210) and assigning a current radio location of the UE to a radio zone of the communication network on the basis of the contents of the report (220). A radio zone comprises a region of a multidimensional radio space over which the communication network extends that is defined by a particular combination of radio field characteristics (220a). Each cell of the communication network comprises a plurality of radio zones. The method further comprises updating, in a database, a trajectory of the UE through the radio space of the communication network with the radio zone to which the current radio location of the UE is assigned (230), and using the updated trajectory to calculate a probability of Handover of the UE to neighbor cells of the current serving cell of the UE (240). The method further comprises initiating a Conditional Handover procedure for Handover of the UE to neighbor cells for which the probability of Handover is above a first Handover threshold value (250).

摘要： The present invention relates to a similarity metric customized to radio measurement in heterogeneous wireless networks and to the use of the similarity metric. Radio measurement values reflecting radio access conditions during different measurement time intervals for at least one mobile terminal having radio access to the heterogeneous multi-carrier network are aggregated into radio measurement scans. Further, for every radio measurement scan related radio measurement configurations prevailing at the time of measurement of the corresponding radio measurement values are aggregated into a radio measurement configuration scan. Then the similarity metric is calculated for a pair of radio measurement scans to generate knowledge on radio coverage in the heterogeneous wireless network in a customized manner through reference to radio measurement configuration scans associated with the pair of radio measurement scans for which similarity metrics is to be calculated.

摘要： A technique for reporting and processing alarm conditions in a communication network is disclosed. In one variant, a network element is presented that comprises a memory and at least one processor coupled to the memory, wherein the memory stores program code that configures the at least one processor to detect, as a first event, at least one alarm condition and to start, in response to detecting the first event, an alarm clearance timer. The program code further configures the at least one processor to detect, as a second event, at least one of expiry of the alarm clearance timer and clearance of the at least one alarm condition and to determine, after detecting the second event, a first performance indicator value of a performance indicator for a first period of time between the first event and the second event. The at least one alarm condition and the first performance indicator value (or information derived from the first performance indicator value) are then reported to a central network management component.
