    Abstract: In a Packet Switched Data Network (PSDN) having a Local Area Network (LAN) interface, an auxiliary controller controls all protocols of the LAN interface through an interrupt routine and transmits a state-monitoring signal after processing the protocols. A main controller compares a transmitting period of the state-monitoring signal transmitted from the auxiliary controller with a critical time and changes a state of the auxiliary controller from a usable state to an unusable state or from the unusable state to the usable state in accordance with a result of the comparison. As a result, even when traffic is congested in a certain LAN interface or a certain LAN interface is infected with a virus to such an extent that the interface fails to operate, an overload in a main processor is prevented.

The UE in a DRX level wakes up periodically to monitor a scheduling channel. The method includes receiving a DRX indicator in a Non-DRX level with continuously monitoring the scheduling channel and transitioning from the Non-DRX level to a DRX level indicated by the DRX indicator. The UE can transition between multiple DRX levels by an explicit command/signaling.

  • Patent number: 8031738
    Abstract: In order to avoid system malfunction, the present invention provides a method of enhancing continuous packet connectivity, known as CPC, for a user equipment, known as UE, in a wireless communications system. The method includes the following steps. A control channel less operation function is activated according to a status variable. The status variable is re-determined when a radio link failure occurs, when a radio link control, known as RLC, unrecoverable error occurs or when transmission of UE CAPABILITY INFORMATION fails, so as to deactivate the control channel less operation function. Preferably, the status variable is CPC_HS_SCCH_LESS_STATUS variable, and the control channel less operation function is HS-SCCH less operation, where HS-SCCH is an abbreviation of “Shared Control Channel for HS-DSCH”.

  • Patent number: 8023530
    Abstract: Physical layer quality of service is provided for a wireless communication system by operationally adapting the physical layer format to the quality of service requirements of transmitted data. The physical layer formats for the data packets are selected based on the quality of service requirements of the data packets. Control information defining the formats is transmitted across the wireless communication link and the data packets are transmitted using the selected physical layer formats.

  • Patent number: 7983230
    Abstract: A method for controlling transmit power of a node in wireless network, such as, e.g., an ad-hoc wireless network operating in accordance with a carrier sense multiple access (CSMA) protocol and where asymmetrical radio links may exist. During a request to send (RTS) and clear to send (CTS) exchange between a first node and a second node, both a request to send (RTS) packet and a probing request to send (PrRTS) packet are transmitted from the first node to the second node. The transmit power and data rate of the PrRTS packet may be different from the transmit power and data rate of the RTS packet. In response, the second node returns a CTS packet that includes a signal to noise ratio (SNR) for both the RTS packet and the PrRTS packet. A correction factor for data transmit power is then computed based in part on both the SNR for the RTS and the SNR for the PrRTS, and a data packet is thereafter transmitted at a power level that has been modified in accordance with the correction factor.

  • Patent number: 7899074
    Abstract: Provided is an apparatus and method for controlling multi-channel access in USN-based MAC. The multi-channel access control apparatus includes a channel scanner, a control channel preoccupier, and an available channel exchanger. The channel scanner scans at least one or more available channels among the N data channels in a Tx sensor node. The control channel preoccupier preoccupies, in the Tx sensor node, the control channel through control channel sensing and back-off and broadcasts a preamble on the control channel periodically. The available channel exchanger detects, in an Rx sensor node, the available channels available to the Tx sensor node on the basis of the received preamble, selects a channel available to the Rx sensor node among the detected available channels, and transmits information about the selected channel to the Tx sensor node.

  • Patent number: 7839883
    Abstract: The present invention concerns methods and apparatus for implementing a multi-user advance reservation system where reservations are specified in terms of flexible constraints, inflexible constraints and business values. The specification of reservations in this manner allows an entity managing the reservation system to arbitrate among reservations received from a user population with a view toward maximizing business value across the user population. In methods and apparatus of the present invention, penalties and rewards associated with various reservation outcomes can be specified in reservations to assist in business value maximization. In an example, a reservation having a low business value may be declined when there is a significant possibility that a reservation having a high business would be submitted during the pendency of service delivery to the user issuing the reservation with a low business value.

  • Patent number: 7836190
    Abstract: The invention is based on the idea of managing multimedia resource reservation by a solution in which, for a first user terminal, a first media terminal is searched and reserved, and a multimedia session is started. A multimedia session request is transmitted from the first user terminal to a second user terminal via an IMS subsystem. A second media terminal is searched and reserved for the second user terminal. The information on the reserved second media terminal is transmitted via the IMS to the first user terminal, which informs the first media terminal of the reserved second media terminal. After that, real-time data traffic can be transmitted via an IP network, e.g., the Internet, between the first media terminal and the second media terminal.

  • Patent number: 7797464
    Abstract: A system and method for optimizing the transmission of signals over a group of wires. In a preferred form of the present invention, a multi-wire bus connects a common card to a plurality of line cards. A framing protocol controls transmissions between the common card and the plurality of line cards. The framing protocol includes a frame having a prefix that identifies in which direction a given transmission will occur. The prefix also identifies over which wire or wires a given line card will receive data. Each of the line cards are configured to interpret the prefix so that at any given time data can be transmitted from the common card to one or more of the line cards by either transmission over a single wire or a plurality of wires.

  • Patent number: 7764610
    Abstract: Upon deciding to start domain access regulation, regulation controller (12) reads out a regulation pattern in accordance with a regulation level which represents a percentage of mobile terminals (24) on which regulation of domain access is to be imposed. Informative information transmission controller (14) instructs a base station (23) to transmit, to mobile terminals (24), informative information in which the regulation pattern read by regulation controller (12) is set. Call controller (11) performs processing to release a signaling connection to the CS domain and processing to switch from an individual channel to a common channel with respect to each of mobile terminals (24), whose percentage is in accordance with the regulation level, and that have transmitted a message for establishing a signaling connection to the CS domain.

  • Patent number: 7701959
    Abstract: Network devices of a digital network for communication between a plurality of devices have a source for transmitting data into the network, and sinks for receiving data from the network. Managers (logical controllers) to which priorities are assigned in a hierarchical order manage connections between sources and sinks. Before setting up a connection, a manager first queries a negotiation administrator to obtain a right to negotiate with other managers and to set up connections. When all other managers having higher priorities also have granted the connection, the manager connects sources and sinks.
