  • Process for operation of a data link
    Patent number: 7961619
    Abstract: The invention relates to a process for the operation of a data link between a base station and one or several mobile stations. According to said process data packets are transmitted between the base station and the mobile stations within transmission phases. The start of each transmission phase is indicated each time through emission of a start signal, and the transmission interface between the base station and the mobile stations for the transmission phase in question is managed by the base station. The data packets are formed with the data of a data stream and a received data stream is formed with the received data packets. The start and the end of each data packet forming operation is each time triggered by the start signals.

  • Smooth Handover in a Wireless Local Area Network
    Publication number: 20080273495
    Abstract: A process for operation of a data link transmitting data packets between a base station and one or more mobile stations within transmission phases. A start signal indicates the start of each transmission phase that is managed by the base station. For preparation of a handover procedure the mobile station switches into a monitoring phase, wherein the radio traffic is listened to and another base station suitable for the data packet transmission is sought. The mobile station performs data packet transmission in every mth transmission phase, “m” designating a natural number greater than “1”, and after data packet transmission has been effected, the mobile station is omitted from the data packet transmission for at least one subsequent transmission phase.
