20140133847 | DEVICE, REMOTE NODE AND METHODS FOR PON SUPERVISION - A wavelength shifter module and a method therein for tuning an OTDR signal to at least one pre-selected wavelength in a passive optical network (PON). The wavelength of the OTDR signal is shifted to a pre-selected wavelength to enable a remote node in the optical distribution network ODN of the PON to forward the OTDR signal to a specific drop section in the ODN. The invention also includes a remote node and a method in a remote node for receiving a wavelength shifted OTDR signal having a preselected wavelength and outputting the wavelength shifted OTDR signal to a specific drop section. Furthermore, the invention involves a method for determining the location of a fault section in a drop section. | 05-15-2014 |

20120319900 | ANTENNA WITH ADJUSTABLE BEAM CHARACTERISTICS - The present invention relates to an antenna comprising multiple array elements with a first and second feeding point, each associated with orthogonal polarizations, each array element has a first and second phase centre each associated with the orthogonal polarizations, the first and second phase centres of said array elements are arranged in at least two columns, and one antenna port connected to the first and second feeding points of at least two array elements with first phase centre and second phase centre arranged in the at least two columns via a respective feeding network. The feeding network comprises a beam forming network having a primary connection, connected to the antenna port, and at least four secondary connections. The beam forming network divides power between the first feeding point and the second feeding point and controls phase shift differences between the respective feeding points with phase centre arranged in different columns. | 12-20-2012 |
20120319752 | LOOK-UP TABLES FOR DELAY CIRCUITRY IN FIELD PROGRAMMABLE GATE ARRAY (FPGA) CHIPSETS - A method, new use for Look-Up Tables (LUTs), and a Field Programmable Gate Array (FPGA) chipset are provided for delaying data signals. The FPGA comprises an input and a set of LUTs operationally connected to and receiving from the interface a data signal and a clock signal. The set of LUTs delay the data signal by a delay so that a corresponding first delayed data signal output from the set of LUTs is so synchronized with the clock signal for appropriate sampling of the delayed data signal to be performed by the FPGA chipset. A process of manufacturing of the FPGA chipset comprises calculating a delay for delaying and synchronising the data signal with a clock signal to meet requirements of the chipset, calculating a number of LUTs for delaying the data signal, and implementing in a data path of the data signal the number of LUTs. | 12-20-2012 |
20120218903 | Component Carrier Selection Method and Apparatus for Random Access Attempts in a Communications Network - A method is provided for determining a location of a mobile device ( | 08-30-2012 |
20120213127 | INDICATING TRANSFER IN AN IMS NETWORK - A method and apparatus for indicating to a node in an IMS network a transfer between two endpoints. A node in a first network determines that a communication session is to be transferred from a first endpoint to a second endpoint. The node includes an indication of at least one of the endpoints, and an explicit communication transfer indicator, in a message. The message is then sent towards the node in the IMS network. This allows the node in the IMS network to determine that a transfer has taken place and, if necessary, take further action. | 08-23-2012 |

20090109907 | MULTIPLEXING MULTIPLE UNSOLICITED GRANT SERVICE (UGS) USERS ONTO A SAME RADIO RESOURCE - The technology in this application multiplexes transmission associated with multiple users onto the same unsolicited grant service (UGS) radio resource(s) in a packet-based, radio communications system. Normally, the radio resources in a packet-based communications system are dynamically scheduled in response to radio resource requests associated with specific user devices, and the scheduled communications are designed not to use the same radio resource at the same time. However, an unsolicited grant of radio resources for communication between multiple user devices and the packet-based communications system is also established. The communications between those multiple user devices and the packet-based communications system use at least some of the same radio resources associated with the unsolicited grant at the same time. Because of this at least partial radio resource overlap/collision, each of the multiple user's data to be transmitted via the UGS is associated with a user-specific radio resource pattern. A user's radio resource pattern permits a radio receiver to extract that user's data from the received UGS signal that include multiple user transmissions. | 04-30-2009 |
