摘要： 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.

摘要： 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.

摘要： Methods and apparatus for identifying a source of quality degradation for a media call flowing in a first direction and a second direction between a mobile-originating user equipment (UE) and a mobile-terminating (MT) UE are presented. In an example method, a network node obtains a set of multiple rules specified respectively for multiple candidate sources of quality degradation for the media call in the first direction. These rules indicate whether a particular candidate source is an actual source of quality degradation based on values of certain key performance indicators (KPIs). The network node identifies, from among the multiple candidate sources of quality degradation, one or more sources of quality degradation by evaluating one or more rules from the set of multiple rules.

摘要： A method in a radio network node is disclosed for handling positioning data in a radio communications network, which radio network node serves a user equipment in a cell. The radio network node obtains positioning data from the user equipment, which positioning data is associated with a positioning measurement for positioning the user equipment. The radio network node associates the obtained positioning data with an on-going trace session of the user equipment. The radio network node then sends a trace record to a network management node, which trace record includes information associated with the positioning data.
