Patent number: 8155079Abstract: There is provided a measuring system comprising: a measuring device configured to measure parameters of a serving cell required for camping into the neighbor cells of the serving cell, to camp into the neighbor cells in order to store reception quality and neighbor cell lists from the neighbor cells; and a base station configured to set parameters of the formed virtual cell such that the virtual cell becomes a tempting destination for a cell reselection, to interfere the serving cell in order to cause the one or more user terminals to camp into the virtual cell, and to catch one or more identifiers of the one or more user terminals camping into the virtual cell after the start of virtual cell transmission.Type: GrantFiled: March 14, 2008Date of Patent: April 10, 2012Assignee: Nethawk OyjInventors: Juha Kumpula, Hannu Toppinen, Jorma Ikäheimo

Patent number: 8081979Abstract: Blocking of service in cellular radio system. An apparatus comprises a processor configured to control a stand-alone base station so that an emulated cell is formed by transmitting a control channel with information of a real cell and with such a transmission power that a subscriber terminal of a cellular radio system is forced to camp in the emulated cell, and to control the stand-alone base station to block service from the subscriber terminal before an integrity protection process is performed between the stand-alone base station and the subscriber terminal.Type: GrantFiled: April 17, 2009Date of Patent: December 20, 2011Assignee: Nethawk OyjInventors: Hannu Toppinen, Janne Pauna

Patent number: 8032168Abstract: A method, device and computer program product for monitoring data transmission connections. The method comprises monitoring data transmission connections between a cellular radio network and a subscriber terminal with two analyzers. With the first analyzer, first connection information is collected on a first data transmission connection of the subscriber terminal to a first cell. With the second analyzer, second connection information is collected on a second data transmission connection of the subscriber terminal to a second cell. The first connection information is transferred from the first analyzer to the second analyzer. In the second analyzer, the first connection information is used combined with the second connection information for analyzing the second data transmission connection.Type: GrantFiled: June 17, 2005Date of Patent: October 4, 2011Assignee: Nethawk OyjInventor: Jorma Ikäheimo

Publication number: 20100211675Abstract: An arrangement and method for analysing the data transferred in communications networks. The fact that though the amount of user plane traffic and data is increasing fast, the amount of signalling traffic is hardly increasing at all, is utilised. In the present system the analysis of the user plane and the control plane is done separately in user plane analysis appliance (206) and protocol analyser (204). The separate analysis results are then combined by certain criteria and the combined data is shown. An at least nearly real-time network data analysis is possible also in the networks with high speed traffic.Type: ApplicationFiled: February 16, 2010Publication date: August 19, 2010Applicant: NETHAWK OYJInventors: Timo AINALI, Jorma IKÄHEIMO, Tommi TALLGREN, Jorma AXELSSON

Publication number: 20080263402Abstract: The invention relates to a method, testing arrangement, simulator and software program for evaluating quality of a transmission channel or a transmission device or a codec. The evaluation is made by using multimedia stream including voice and video frames. The multimedia frames used in the evaluation are generated by using fractal functions both in the transmitting device and the receiving device.Type: ApplicationFiled: March 4, 2008Publication date: October 23, 2008Applicant: NETHAWK OYJInventor: Vinski Braysy

Publication number: 20080037435Abstract: The invention relates to a method, measurement arrangement, analyser and analyser program for debugging transmission failures in a telecommunication network. In the method, the analyser utilizes both internal events of a telecommunication component and signalling messages transmitted in the telecommunication network. Internal events and external signalling messages are combined or correlated for speeding de-bugging.Type: ApplicationFiled: August 10, 2006Publication date: February 14, 2008Applicant: NETHAWK OYJInventor: Jouko Sankala

Publication number: 20070198218Abstract: There is provided a protocol analyser arrangement, comprising: more than one analyser module (100A, 100B, 100C) including: at least a processing unit (110) for controlling functions of the analyser module in each of the analyser modules; and a data transfer unit (106) coupled to the processing unit for communicating data with a data transmission system (221) in at least one analyser module. The more than one analyser module each further include a communication unit (108) coupled to the processing unit for communicating with one or more other communication units of the more than one analyser module thus forming a cluster of the analyser modules (210); and a processing unit (110) of any analyser module of the cluster of the analyser modules is configured to share processing resources of the analyser module with one or more other analyser modules in the cluster of the analyser modules.Type: ApplicationFiled: February 20, 2007Publication date: August 23, 2007Applicant: NETHAWK OYJInventors: Jouko Sankala, Tapio Taipale
