Publication number: 20140086068Abstract: A technique for controlling and handling set up of a probe tunnel stretching from an access network node through a core network towards a core network node is described. In a method implementation, probe tunnel set up control comprises determining a First Fully Qualified Tunnel Endpoint Identifier (F-TEID) associated with the core network node and sending a probe tunnel set up instruction to the access network node. The instruction commands the access network node to locally set up the probe tunnel towards the core network node based on the F-TEID.Type: ApplicationFiled: March 28, 2011Publication date: March 27, 2014Applicant: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Tamas Borsos, Åsa Bertze, András Veres

Publication number: 20130294263Abstract: One or more embodiments of a method and device taught herein provide for monitoring wireless terminal behavior in a wireless communication network, where each wireless terminal has a defined terminal type. Data describing the behavior of a plurality of wireless terminals in the wireless communication network is obtained. Based on the obtained data, an aggregated severity score for a given terminal type is determined that is indicative of the extent to which one or more of a plurality of performance criteria have not been met by wireless terminals of the given terminal type. If the aggregated severity score for the given terminal type exceeds a corresponding severity score threshold, one or more of a plurality of predefined actions are performed based on the extent to which the threshold is exceeded.Type: ApplicationFiled: January 25, 2013Publication date: November 7, 2013Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Péter Hága, Zsolt Kenesi, László Toka, András Veres

Patent number: 8554202Abstract: One or more embodiments of a method and apparatus taught herein provide for the detection of faulty wireless terminals in a wireless communication network. According to an exemplary method, an occurrence of one or more service incidents occurring for a wireless terminal during an observation time period is detected. For each service incident, a service quality score indicative of the severity of incident is determined. A performance metric is calculated responsive to the service quality scores of the wireless terminal occurring during the observation time period. The wireless terminal is determined to faulty if the performance metric exceeds a service quality threshold. A corresponding network node operable to implement the method is also disclosed.Type: GrantFiled: May 4, 2012Date of Patent: October 8, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Péter Hága, Zsolt Kenesi, András Veres

Publication number: 20130176871Abstract: 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.Type: ApplicationFiled: December 21, 2009Publication date: July 11, 2013Applicant: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Åsa Bertze, András Rácz, András Veres

Patent number: 8442947Abstract: A method of handling performance data comprising a set of events is described. An event record for each event is stored as a set of blocks, each block containing one or more attributes of the event. The storage space occupied by each event record in is then reduced in discrete steps, each step including a reduction process that reduces the size of one of the set of blocks. This enables the provision of intermediate records between events and counters so that new event records contain complete details of their event, older event records contain less information, and even older event records may contain only high-level (counter) information.Type: GrantFiled: July 3, 2008Date of Patent: May 14, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Andras Veres, Péter Vaderna, Ferenc Kubinszky, Péter Benkö, Gergely Szabó, Szabolcs Malomsoky, Tamás Borsos

Publication number: 20120329471Abstract: 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.Type: ApplicationFiled: February 16, 2010Publication date: December 27, 2012Inventors: József Barta, András Veres

Patent number: 8284044Abstract: A system and method of handling poll-based alarms. The method begins by detecting a high-priority problem in a network. Next, network elements in the network related to the high-priority problem are mapped. The mapping step includes grouping network elements into focus groups wherein each focus group includes network elements having the same alarm. The mapped network elements are then polled for alarms. The polled alarms of the network elements are then correlated and processed.Type: GrantFiled: December 23, 2008Date of Patent: October 9, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: András Veres, Szabolcs Malomsoky, Gergely Szabó, Tamas Borsos, Péter Benkō, Peter Vaderna, Ferenc Kubinszky

Publication number: 20120163194Abstract: 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.Type: ApplicationFiled: August 28, 2009Publication date: June 28, 2012Inventors: Äsa Bertze, Andras Valkó, András Veres

Patent number: 8175059Abstract: A method and apparatus for transferring buffer data from a first network node to a second network node during a mobile handover between cells. In order to improve the speed at which buffer data is transferred during a handover, a connection using a congestion control protocol is established between the two nodes prior to the handover. Dummy data is sent over this connection, in order to approach or reach the available data transfer rate, and at the handover, the dummy data is replaced with buffer data.Type: GrantFiled: March 30, 2007Date of Patent: May 8, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Andras Veres

Publication number: 20110222414Abstract: 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.Type: ApplicationFiled: March 12, 2010Publication date: September 15, 2011Inventors: Tamas Borsos, Andreas Olsson, Hakan Sture Magnus Svensson, András Veres, Asa Bertze
