20080280611 | Smooth Hard Handover Method, Mobile Station and Base Station Adapted For The Method - The present invention relates to a cellular radio communications system and especially a method, a mobile station and a base station for a smooth hard handover. The smooth hard handover includes preparing radio links in selected base stations for potential communication with a mobile station. This is similar to selecting base stations for the active set in the prior art soft handover. A difference is though that just one radio link is actively used for transmission. The handover from the active to a prepared radio link is quick and safe, as compared to conventional hard handover, because of the preparation, while requiring a less complex system architecture then the conventional soft handover. The smooth hard handover can replace the soft handover. | 11-13-2008 |

20130176871 | Network Bottleneck Management - The invention provides a method by which a network element in a telecommunications network can report factors that have limited the performance of a UE in an observation period. A bottleneck score is calculated for each factor, the bottleneck score providing a measurement of the extent to which that factor has limited the performance of that UE compared to other factors in the observation period A data record for the UE is populated with the bottleneck scores and sent in a report towards upper layer management functions. When these reports are received (e.g. by a MME) they may be complemented with global entities of the users and aggregated measures created. The bottleneck scores may be calculated by collecting per-UE performance counters from a radio scheduler and estimating an actual UE performance from the collected performance counters, replacing one or more of the measured performance counters with a hypothetical value reflecting a particular factor operating ideally, and estimating a theoretical user performance based on the hypothetical value and remaining performance counters, and assigning a bottleneck score for that factor by comparing the estimated actual user performance with the estimated theoretical user performance. | 07-11-2013 |
20130331079 | Self-Organizing Network - According to a method of operating a cellular telecommunications network to implement self-organizing network (SON) functionality, a network manager (NM) SON function is implemented in a NM, and a plurality of network elements (NEs) each implement a NE SON function.

The NM SON function provides the allowable set in a NE configuration attribute sent to the NE SON function. The conditional actions are configured in the NE SON function and ensure consistency and integrity of decisions taken at individual cells. | 12-12-2013 |
20140018098 | METHODS AND ARRANGEMENTS FOR HANDLING POSITIONING IN A RADIO COMMUNICATION SYSTEM - A method in a first radio network node for handling position measurements is provided. The first radio network node receives from a second radio network node a position measurement associated with a user equipment, and a system frame number.

20140169277 | Method and Arrangement in a Telecommunication System - 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. | 06-19-2014 |
20140219107 | Technique for Determining Correlated Events in a Communication System - A technique for determining a correlation among events occurring in one or more network elements is provided. The correlation among the events results from a propagation of a root event through communication entities of the one or more network elements. In a method implementation the technique comprises the step of receiving a plurality of event messages from one or more network elements, wherein an event message pertaining to an event reported by a particular network element signals an occurrence context, the occurrence context comprising one or more context identifiers describing an internal communication state of the communication entity in which the event occurred at the time when the event occurred. In another step, a set of correlated events linked by identical context identifiers is determined. Based on the set of correlated events, the root event may be identified. | 08-07-2014 |
