20110222414 | METHOD AND APPARATUS FOR ACTIVE PROBING OF TUNNELED INTERNET PROTOCOL (IP) TRANSMISSION PATHS - A method, apparatus, and system in an IP-based mobile communication network for actively probing a tunneled transmission path from a base station such as an eNB to a core network. A UE-emulator emulates a User Equipment (UE) and provides emulated NAS signaling to a Probe Connection Control (PCC) unit in the base station, which establishes the tunneled transmission path by forwarding the NAS signaling received from the emulator toward the core network. The PCC stores associated communication endpoints and UE-assigned IP addresses. A Probe Traffic Control (PTC) unit within the base station utilizes the stored endpoints and IP addresses to generate probe traffic through the tunneled transmission path toward a probe server or another base station configured as a probe reflector. The probe reflector collects and reports path properties such as packet loss, delay, jitter, and throughput. | 09-15-2011 |
20120163194 | Handling Alarms Based On User Session Records - A method is provided in a network management node for handling an alarm caused by a fault in a communications system. An alarm caused by a fault in the communications system is received from a first network element within the communications system. The alarm is associated with an identity of the first network element, and an alarm time associated with the time when the alarm was active. After receiving the alarm, the network management node sends a request to a user activity database, requesting one or more matching records. Each of the matching records is requested to comprise an identity equal to the identity of the first network element associated with the alarm, and a record time period that comprises the time when the alarm was active. The network management node receives one or more matching records from the user activity database, which one or more matching user session records identify the user sessions being affected by the alarm, and then handles the alarm based on the one or more matching user session records. | 06-28-2012 |

20120275331 | Random Data Stream Sampling - There is provided a method of sampling data elements from a data stream for subsequent analysis, the data stream comprising a plurality of data elements, wherein each data element has a respective unique quasi-random identifier determined from a set of identifiers, the method comprising selecting data elements from the data stream whose identifiers are within a first element selection range to give a set of selected data elements, the first element selection range being a subset of the set of identifiers; wherein, once the set of selected data elements comprises a predetermined number of data elements, the method further comprises: determining a second element selection range as a proper subset of the first element selection range; discarding data elements from the set of selected data elements whose identifiers are not within the second element selection range; and selecting at least one further data element from the data stream whose identifier is within the second element selection range for the set of selected data elements. | 11-01-2012 |
20120295631 | Method of Bringing a Wireless Telecommunication Cell Into DTX Mode - In a method and system for automatically bringing a cell into DTX mode, a time period is introduced during which the outcome of bringing a cell into DTX mode is observed. The cell can return to a transmission mode if the outcome is non-satisfactory as determined by some criteria. Hereby an improved automated DTX method can be implemented which helps save energy in a cellular radio system. | 11-22-2012 |
20120307791 | Methods and Devices for Controlling Handover - Methods and devices in a cellular radio system for handling repeated handovers of a user equipment between a pair of cells is provided. It is determined if the user equipment is in one of two states, moving state or stationary state. Based on the determination different actions can be taken. For example threshold optimizations for reducing repeated handover may only be applied to a user equipment determined to be in a stationary state or a user equipment determined to be in a stationary state to can be nailed to the best cell of said pair of cells by not allowing the user equipment to handover to the other cell of said pair of cells. | 12-06-2012 |
20120329471 | Method for Energy Control in a Cellular Radio System - Methods and devices enabling improved switch-on procedures during the reactivation of base stations already switched off to save power are provided. In accordance with one embodiment a method of activating a de-activated cell in a cellular radio system is provided. First measurements are collected from a number of user equipments connected to the cellular radio system. Based on the collected measurements a model for mapping a cell, the best cell, providing the least power increase in the cellular radio system when activated is constructed. When the traffic demand of the cellular radio system cannot be served using already activated cells it is determined to activate the cell that is mapped as the best cell to be activated. Hereby, the cells of a cellular radio system can be managed to maximally utilize the energy used in the system. | 12-27-2012 |
20130133041 | Data Traffic Control in a Communication Network - A method and apparatus for controlling data traffic in a communications network. The server determines that network conditions are suitable for sending delay tolerant data traffic, and as a result of the determination, it transmits a grant message to at least one client device, the grant message informing the client device that it is permitted to send or receive delay tolerant data traffic. | 05-23-2013 |
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 |
