  • Patent number: 6900683
    Abstract: A semiconductor arrangement is provided for generating a predetermined time delay. Two clocks are connected to two parallel, redundant semi-conductor circuits emitting clock signals from multiplexers. The redundant circuits receive delayed clock signals from one of the clocks, and from the other clock, clock signals that are delayed in adjustable delay circuits to be phased in with the clock signals from the first clock. A number of delay elements and a first reference number of delay elements, providing a predetermined delay time, are connected in a reference delay circuit. A quotient of the two numbers is stored. One of the semi-conductor circuits is replaced by an alternative semi-conductor circuit, the reference delay circuit of which is set on the predetermined delay time, corresponding to a second reference number of delay elements. An adjustable delay circuit is set on the same delay time as the replaced semi-conductor circuit by means of the second reference number and the quotient.

  • Publication number: 20040012429
    Abstract: The figure shows a unit (5) for distributing clock signals (SA1, SB1) in telecommunication systems. The unit is provided with a semiconductor arrangement (ADA, CTA, RDA) for generating a predetermined time delay. Two clocks (CLA, CLB) are connected to two parallel, redundant semi-conductor or circuits (SCA, SCB) emitting clock signals (SA2, SB2) from multiplexers (MXA, MXB). These receive delayed clock signals (SA1) from one of the clocks (CLA), and from the other clock (CLB) clock signals (SB1) that are delayed in adjustable delay circuits (ADA, ADB) to be phased in with the clock signals (SA1) from the first clock Thus, a number of delay elements in the delay circuit (ADA) are connected and a first reference number of delay elements, providing a predetermined delay time, are connected in a reference delay circuit (RDA). A quotient of the two numbers is stored.

  • Patent number: 6622251
    Abstract: In a WLAN where an AP and MTs use a duplex airlink having a MAC frame structure to communicate with each other, the AP places wakeup PDUs at different locations in a MAC frame to allow the MTs to conserve energy by maximizing sleep time. In other embodiments, the wakeup PDUs are sequenced by MAC-ID so that a MT can conclusively determine whether remaining wakeup PDUs in a sequence can contain its MAC-ID, and go to sleep early if they cannot. In another embodiment, a wakeup PDU type can indicate to a corresponding MT whether the MT can expect downlink data later in the same MAC frame. In addition, the wakeup PDU type can indicate to the MT that the MAC frame that it should awaken and remain awake to receive downlink data in the future.

  • Patent number: 6594238
    Abstract: In a mobile communications system that provides packet data services, a packet data connection is established between a mobile station and a radio access network. The state of the connection specifies one of plural different types of radio channels bearing the connection over the radio interface. The connection state preferably also may specify other parameters including for example, one of plural different mobility management schemes tailored to the selected channel type or channel bit rate(s). The connection is dynamically adapted to an optimal state based on one or more conditions relating to the connection. For example, one or more traffic parameters are determined for the connection and used to predict a future value of that parameter. Based on the predicted parameter value or values, an optimal connection state is determined and implemented.

  • Patent number: 6463069
    Abstract: A buffering technique handles dynamic and static phase deviations between signals from at least two redundant planes. Dynamic phase deviations between planes are handled in a first buffer and static phase deviations between planes are handled in a second buffer. A register arrangement is provided in which is stored information relating to a first difference between read and write pointers for a plane of the second buffer, and information relating to the current difference between the read and write pointers of the same plane in the static buffer is stored after a reload operation. The first and current differences are compared to provide a control signal which is used for the next reload operation in the dynamic buffer which is controlled by the control signal to avoid end of buffer in the second buffer if the difference between the first and the current differences exceeds a given number of positions.

  • Patent number: 6169737
    Abstract: The invention relates to a method and device for switching user data, belonging to a connection, between different time slots in a switch or a switch stage such that sequence and frame integrity are preserved. According to the invention, an efficient algorithm is utilized for determining distribution information, in form of storage positions in one or more control memories in the switch. User data is caused to be switched, according to this distribution information from the algorithm, such that these user data maintain the same reciprocal time order through the switch or switch stage. The distribution information determined by the algorithm assures sequence integrity and at the same time minimizes the delay of user data through the switch and/or switch stage. The algorithm also generates control information in form of delay values for delaying some user data such that data belonging to incoming time slots in one and the same frame are assigned to outgoing time slots in the same frame.

  • Patent number: 6157639
    Abstract: Sequence integrity and frame integrity are preserved in switching wideband connections through a switch or a switch stage. The speech memory in a switch stage in the switch is extended to include storage positions that in number correspond to the number of time slots in two frames. These storage positions are arranged into two parts of the same size in the speech memory. Furthermore, there is provided a delay control unit in the time switch stage for generating delay information based on control information in the control memory of the switch stage and a determined part of the counter information from a time slot counter circuit. This delay information controls, for each time slot, to/from (depending on if the speech memory is arranged in an outgoing stage or an incoming stage) which one of the first and second parts of the speech memory that user data is switched.
