20090122812 | SAFE START-UP OF A NETWORK - A method for start-up of a network, including a number of nodes, which are connected via channels. The nodes exchange information in the form of messages via the channels. The transition phase of a synchronizing node from its initial phase to a synchronized phase is separated in a first integration phase and a second subsequent cold-start phase. A synchronizing node in the integration phase listens to messages being sent from nodes in the synchronized phase and only reacts to an integration message (i-frame) if the integration message is a valid message. Furthermore, a synchronizing node, wherein integration of the synchronizing node to a set of already synchronized nodes was not successful after a specifiable period, changes into the cold-start phase, in which a cold-start procedure of the node is extracted, wherein in the cold-start phase the node does not react to integration messages of a node in the synchronized phase. | 05-14-2009 |
20100020828 | MULTIROUTER FOR TIME-CONTROLLED COMMUNICATION SYSTEM - To relay messages in a time-controlled communication system with a star coupler arranged as a multirouter, messages arriving via ports are relayed according to a rule defined in the star coupler. Relaying paths are switched according to a rule defined in the star router which describes relaying paths for messages, namely in the synchronized operating state depending on the time according to the global time basis of the communication system. Two relaying paths can occur simultaneously in at least one time slot whereby they are in disjunction to one another. Each port belongs to only one relaying path respectively at any time. A check is conducted on the basis of a message's content as to whether the relaying of the message complies with an acceptance rule. Relaying of the message to those target ports which do not match the rule is cancelled or ended under the invalidation of the message. | 01-28-2010 |

20150078399 | Method and Apparatus for Consistent Modification of the Schedules in a Time-Controlled Switch - The invention relates to a method for dynamic modification of the schedules in a time-controlled switch for relaying time-controlled messages in a real-time computer system, wherein at least one active schedule and at least one new schedule are stored at a point in time in a switch, wherein, at a specified changeover time in the active interval of a sparse time base, the active schedule is deactivated and a new schedule is activated. | 03-19-2015 |

20090046670 | Method for Data Transmission in a Radio Communication System - A method for data transmission in a radio communication system, in which data of a plurality of subscribers is combined with the aid of a multiplexing method to form frames, and is transmitted by means of sub-carriers. At least two frame structures are provided for transmission of the frames, with the frame structures differing in the respectively associated number of pilot signals and/or in the distribution or grouping of associated pilot signals. Each subscriber determines an individual progress speed, and each subscriber is allocated to one of at least two speed ranges, depending on the progress speed. A frame structure which is individually associated with the speed range, on the one hand, and an individually associated number of sub-carriers, on the other hand, are used in order to transmit the data from subscribers who are allocated to an identical speed range on the basis of their progress speed. | 02-19-2009 |
20090156225 | Method, apparatus, and computer program product for signaling allocation of neighbor cells - A method, user equipment, network device, and software product employ indicators from a plurality of respective cells to indicate a difference, if any, regarding allocation in the respective cell as compared to neighbor cells. Mobility measurements are then performed according to the indicators, and also on the basis of configuration of a cell where the measurements are performed. | 06-18-2009 |
20100029291 | Method for the time-based control of an upward signal transmission in a radio communication system - A method controls a time-based transmission of signals of a subscriber terminal for synchronous reception at a base station of a radio communication system. Upon detection that a determined time offset of received signals is equal to or greater than a predetermined threshold value, a change from one-step control commands to multi-step control commands for controlling the time-based transmission of the subscriber terminal is performed by the base station, or a synchronization procedure is initiated by means of a randomly chosen access channel by the subscriber terminal. | 02-04-2010 |
