    Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.

    Abstract: We generally describe a system (100) for antenna beam selection in a radio access network. The system (100) comprises a measurement module (102) which is configured to obtain channel quality measurements of a plurality of beams usable to serve a user equipment (112) in the 5G radio access network. The system (100) further comprises a training module (104) coupled to the measurement module (102), wherein the training module (104) is configured to generate a machine learning model based on the channel quality measurements. The system (100) further comprises a prediction module (106) coupled to the training module (104), wherein the prediction module (106) is configured to receive the machine learning model from the training module (104), and select, based on the machine learning model, one of the plurality of beams used to serve the user equipment (112).

    Abstract: The invention comprises a method for controlling an outage of a network element (300) in a cellular network (40) using an outage database (130), the outage database containing for each of a plurality of the network elements (300) controlled by the cellular network at least the following network element dependent information: first operating parameters describing an error free operation of the corresponding network element, outage detection rules indicating when a outage for the corresponding network element is present, outage compensation rules indicating how the outage of the corresponding network element should be compensated, the outage compensation rules including compensation parameters to be used by compensating network elements (300b-300g) in order to compensate the outage of one of the network elements (300a). The method comprises the steps of: continuously receiving current operating parameters for a plurality of network elements (300), updating the first operating parameters and the outage detection rules for the plurality of network elements taking into account the current operating parameters, detecting an outage for one of the network elements by comparing the received current operating parameters to the outage detection rules for said one network element, wherein if an outage is detected for said one network element, determining and applying the outage compensation rules for said one network element (300a), wherein applying the compensation rules includes optimizing the compensation parameters in order to calculate optimized operating parameters for the compensating network elements (300b-300g) used to compensate for the outage of said one network element, evaluating the application of the compensation rules, and storing the optimized operating parameters in the compensation rules as starting parameters for a future optimization of the compensation parameters in case of an outage of said one network element in dependence on the evaluation.

    Abstract: A technique for predicting radio quality in a wireless communication network depending on assumed positions of one or more base stations in an area to be covered by the wireless communication network is disclosed. A method implementation of the technique is performed by a computing unit and comprises the steps of determining, for a selected position in the area with respect to assumed positions of the one or more base stations, blocking object features indicative of a spatial pattern of blocking objects present in fields of view between the selected position and the assumed positions of the one or more base stations, and determining, based on the determined blocking object features, a predicted radio quality at the selected position using a machine learning model trained to map blocking object features for selected positions with respect to one or more base station positions to corresponding radio qualities at the selected positions.
