Patent number: 9526045Abstract: The present invention relates to a radio resource controller (220a) for controlling radio resources of a serving radio access node (100a). The controller is configured to assign particular radio resources of the serving radio access node to a radio communication session established between the serving radio access node and a particular mobile station, and to push session information (UE_id; UE_ctx_ptr) of the radio communication session into a common data repository (320) accessible to a further radio resource controller (220b) controlling radio resources of a further radio access node (100b). The session information comprise a mobile identifier (UE_id) that may be used by the particular mobile station for resumption of the radio communication session, and further allow retrieval of contextual communication parameters (UE_ctx) used by the serving radio access node for radio communication with the particular mobile station during the radio communication session.Type: GrantFiled: November 5, 2012Date of Patent: December 20, 2016Assignee: Alcatel LucentInventors: Hajo-Erich Bakker, Lutz Ewe, Siegfried Klein, Ulrich Barth

Patent number: 9439122Abstract: The invention relates to a method for performing a handover of a mobile device from a source cell to a target cell in a cellular wireless telecommunication network, the method comprising the following steps: configuring the mobile device to transmit a first handover trigger signal to the source cell, when a difference between a signal strength of the target cell and a signal strength of the source cell as measured by the mobile device is above a first threshold (105; determining (S1) if a cell traffic load in the source cell is above a cell traffic load threshold; if so, configuring the mobile device to transmit a second handover trigger signal to the source cell, when a difference between a signal strength of the target cell and a signal strength of the source cell as measured by the mobile device is above a second threshold (100), wherein the first threshold is larger than the second threshold.Type: GrantFiled: December 20, 2011Date of Patent: September 6, 2016Assignee: Alcatel LucentInventors: Hajo Bakker, Lutz Ewe, Markus Gruber

Patent number: 8289922Abstract: A mobile terminal is attached to a first network of a first technology type RAT1. The mobile terminal transmits UE capability information to the first network by a plurality of containers. Each container relates to one type of technology which is supported by the mobile terminal. Each container includes an indicator tag identifying the RAT to which its contents relate. On receipt of the containers, the first network decodes the content of the container that is indicated to be of its own technology type. If there is a neighbouring network of another technology type with which the mobile terminal is compatible, the first network sends the relevant container to the second network, where its content is decoded. The second network may return generalized information derived from the container back to the first network. This mechanism provides a content-agnostic approach for transferring mobile capability information between networks of different technology types.Type: GrantFiled: August 5, 2008Date of Patent: October 16, 2012Assignee: Alcatel LucentInventors: Lutz Ewe, Rolf Sigle

Publication number: 20090046596Abstract: A mobile terminal 1 is attached to a first network 2 of a first technology type RAT1. The mobile terminal 1 transmits UE capability information to the first network 2 by a plurality of containers. Each container relates to one type of technology which is supported by the mobile terminal. Each container includes an indicator tag identifying the RAT to which its contents relate. On receipt of the containers, the first network 2 only decodes the content of the container that is indicated to be of its own technology type. If there is a neighbouring network 6 of another technology type with which the mobile terminal is compatible, the first network 2 send the relevant container to the second network, where its content is decoded. The second network may return generalized information derived from the container back to the first network. This mechanism provides a content-agnostic approach for transferring mobile capability information between networks of different technology types.Type: ApplicationFiled: August 5, 2008Publication date: February 19, 2009Inventors: Lutz Ewe, Rolf Sigle

Patent number: 6479890Abstract: A microsystem comprises a flexible foil, a plurality of semiconductor elements embedded in said flexible foil, and a connection line arranged substantially on said flexible foil and used for electrically connecting at least two semiconductor elements. For producing the microsystem, electronic components are first integrated in a semiconductor layer provided on a wafer. Subsequently, the semiconductor areas which are not required between the electronic components are etched away, whereupon the flexible foil is applied. A connection line is then applied to the flexible foil so as to interconnect the individual semiconductor elements. Finally, the semiconductor is etched away from the back so as to obtain the microsystem in the case of which the individual semiconductor elements are mechanically connected only by the flexible foil but no longer by the semiconductor substrate.Type: GrantFiled: August 31, 2000Date of Patent: November 12, 2002Assignee: Fraunhofer-Gesellschaft Zur Foerderung Der Angewandten Forschung E.V.Inventors: Hoc Khiem Trieu, Wilfried Mokwa, Lutz Ewe
