Patent number: 11470199Abstract: A conferencing device receives an indication that a mobile device is in proximity to the conferencing device. The conferencing device receives information, directly from the mobile device, that indicates that the conferencing device is to establish or join a communication session with one or more communication endpoints. The information that indicates that the first conferencing device is to establish or join the communication session with the one or more communication endpoints is based on information that is personal to a user of the mobile device. Once the communication session is established, the conferencing device communicates with the one or more communication endpoints in the communication session. In an alternative embodiment, a printer/scanner can be managed based on personal information received directly from the mobile device.Type: GrantFiled: February 22, 2018Date of Patent: October 11, 2022Assignee: Avaya Inc.Inventors: Torbjörn Karlsson, Peter Fredriksson, Tommy Edlund

Patent number: 7724768Abstract: Transmission unit comprising a first unit (CM_SCHDR) receiving scheduled first data (DATA2, DATA3) for transmission on at least a first channel, a power control unit (PWR_CTRL) for the first channel responsive to a respective closed loop power regulation signal (TCP_CMD), under which at least the transmit power rate of change is limited to a predetermined value per time unit, a packet data scheduler (HS_SCHDR) scheduling second data packets (DATA1), such as HSDPA data. A permitted power (P_PERM(t)) is defined as the maximum value of either the actual power of a previous instance (P_HS(t?1)) added with the predetermined value (d) or the determined possible power (P_POS(t)). Moreover, an available power is resolved. According to one aspect, the scheduling is performed within these limits. According to a further aspect the power level of the signaling and control channel (HS-SCCH) is further regulated during a transmission interval taking account of shared packet data channel (HS-PDSCH) power level.Type: GrantFiled: October 5, 2004Date of Patent: May 25, 2010Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Roland Carlsson, Torbjorn Karlsson

Patent number: 6400966Abstract: A base transceiver station for a mobile communications system is disclosed, which is divided into a plurality of functional units that enables the signal processing resources to be flexibly allocated and cost-effectively implemented in hardware. A flexible communications interface is created between the base transceiver station units which allows the signal processing resources within the units to be used more efficiently. Essentially, the base transceiver station hardware is dimensioned to statistically distribute the signal processing resources among the different radio transmission services available. Consequently, the allocated base transceiver station hardware can be used more efficiently, which minimizes the overall size and weight of the base station.Type: GrantFiled: October 7, 1997Date of Patent: June 4, 2002Assignee: Telefonaktie Bolaget LM Ericsson (Publ)Inventors: Rutger Andersson, Paul Teder, Torbjörn Karlsson

Patent number: 6167240Abstract: A system and a method reduce interference in a cellular communication system including at least one controlling arrangement communicating with a number of base stations, each of which serves a cell, and a number of mobile stations controlled by the base stations. Each base station includes a detecting device for detecting interfering signals from one or more mobile stations controlled by other base stations. The base stations also include an alarm activating device for activating the transmission of an alarm signal if interference is detected. The controlling arrangement includes a device for requesting identification of all mobile station in the neighborhood of the interfered base station. A device is also provided for establishing by which base station an interfering mobile station is controlled, and the base station controlling the interfering mobile station takes the appropriate action to reduce the interference level.Type: GrantFiled: May 29, 1998Date of Patent: December 26, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Roland Carlsson, Torbjorn Karlsson

Patent number: 5781425Abstract: The invention relates to the determination of short-circuit power (SCC1, SCC2) in an electric power network (N1, N2) for alternating current, which at a connection point (J1, J2) is connected to a converter installation (PL) for transmission of high-voltage direct current. A converter (SR1, SR2) comprised in the converter installation operates with a control angle (.alpha.1, .alpha.2). Power values (MQ(t'.sub.0)), (MQ(t'.sub.k), MQ(t'.sub.n)) of reactive power (Q1, Q2) consumed by the converter and voltage values (MU(t'.sub.0)), (MU(t'.sub.k), MU(t'.sub.n)) of the voltage (U1, U2) of the power network, sensed at the connection point, are formed and stored at a first calculating time (t'.sub.0) and at least one second calculating time (t'.sub.k, t'.sub.n). During a measurement interval (t1-t2) which at least partly coincides with the calculating interval (t'.sub.0 -t'.sub.n), the control angle (.alpha.1, .alpha.2) of the converter is given a control-angle addition (.DELTA..alpha.1, .DELTA..alpha.2).Type: GrantFiled: March 25, 1997Date of Patent: July 14, 1998Assignee: Asea Brown Boveri ABInventor: Torbjorn Karlsson
