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. Each NE SON function is associated with one or more network cells. The NM SON function obtains operational data relating to the network and evaluates a current network condition. Based on the current network condition, the NM SON function determines an allowable set of configuration parameters and conditional actions, which defines combinations of cell configuration parameters that a NE SON function is permitted to use when reconfiguring a cell. 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 |

20150055479 | Technique for Cable Interface-Based Load Balancing Between Cells - A technique for cable interface-based load balancing between first and second cells is described. Each cell comprises cable and air interfaces defining a parameter set comprising load statuses of the cable and air interfaces. A method aspect being performed in a control entity comprises the steps of determining, in the first cell, the parameter set of the first cell, obtaining the parameter set of the second cell, determining whether the load statues of the cable and air interfaces of the first cell are low, whether the air interface load status of the second cell is low, and whether the cable interface load status of the second cell is high, and reconfiguring, if a result of the determination is affirmative, at least one air interface configuration parameter of the first cell so as to off-load at least a part of mobile-originated traffic from the second cell to the first cell. | 02-26-2015 |
20150181022 | Technique for Performance Management in a Mobile Communications Network - A technique of generating statistics for a performance metric of a mobile communications network is presented. The performance metric depends on at least a first parameter and a second parameter, wherein the first and second parameters each can be categorized in two or more non-overlapping sets of parameter values. Different combinations of first and second parameter value sets are defined. A method implementation of the technique comprises receiving performance metric values, first parameter values and second parameter values. A particular performance metric value is associated with the first and second parameter values prevailing when the particular performance metric value was acquired. The method further comprises identifying groups of performance metric values for which the associated first and second parameter values match the first and second parameter value sets of an individual combination, and generating the performance metric statistic from the identified groups of performance metric values. | 06-25-2015 |
20150257162 | Controlling Bandwidth Usage of an Application Using a Radio Access Bearer on a Transport Network - A technique for controlling bandwidth usage of an application using a Radio Access Bearer (RAB) on a Transport network (TN). An example method comprises obtaining statistical data indicative of data frames lost on the RAB. Moreover, a first momentary congestion bitrate is calculated from a number of data packets actually lost on the TN based on the received statistical data and a second momentary congestion bitrate is calculated from a number of data packets actually dropped due to a drop policy applied to the application. Accordingly, a bitrate to be applied to the application by the drop policy is calculated based on the first and second momentary congestion bitrates. Finally, the drop policy is updated based on the bitrate. | 09-10-2015 |
20150289165 | INTRODUCING SIMPLE RLC FUNCTIONALITY TO NODE B - Techniques for processing downlink data transmitted in a mobile communication system between a control node of a radio access network and a mobile terminal are disclosed. A method of processing downlink data transmitted in the mobile communication system between the control node and the mobile terminal includes determining, in a radio access node of the radio access network, at least one Radio Link Control (RLC) Protocol Data Unit (PDU) from a plurality of RLC PDUs transmitted by the control node. The determined at least one RLC PDU contains a payload. The method further includes creating, in the radio access node, at least one replacement RLC PDU to be further used instead of the determined at least one RLC PDU. The at least one replacement RLC PDU contains a payload which size is smaller than the size of the payload of the determined at least one RLC PDU. | 10-08-2015 |
20150296395 | Technique for Evaluation of a Parameter Adjustment in a Mobile Communications Network - This disclosure describes a technique for evaluating a parameter adjustment in a mobile communications network using a multivariate performance model that models a dependency of a performance metric for the mobile communications network on at least two parameters. A parameter is selected to be adjusted for a first network entity, where at least one second network entity is potentially affected by the parameter adjustment for the first network entity. The multivariate performance model is used to determine a change of the performance metric for the first network entity resulting from the parameter adjustment, and a change of the performance metric for the at least one second network entity resulting from the parameter adjustment for the first network entity. Then, the parameter adjustment is evaluated based on the performance metric changes for the first and second network entities. | 10-15-2015 |
20160127929 | TECHNIQUE FOR REPORTING MEASUREMENTS RELATED TO RANDOM ACCESS ATTEMPTS - A technique for collecting and reporting measurements related to Random Access, RA, attempts from a user equipment, UE, towards an evolved node B, eNB, is disclosed. In a first method aspect, the method is performed in the UE and comprises the steps of collecting at least one measurement from each single one of a plurality of the RA attempts, and reporting the collected measurements to one of the eNB and a management entity. In a second method aspect, the method is performed in the eNB and comprises the steps of collecting at least one measurement from each single one of a plurality of the RA attempts, and reporting the collected measurements to the management entity. | 05-05-2016 |
