Abstract: A time-frequency resource allocation planner for planning allocation of time-frequency resources to sustain communication links from a common transmitter (TX) to multiple receivers (RX1, . . . , RXK) in a wireless OFDMA communication system includes a resource block selector configured to select a set (RBS) of time-frequency resource blocks (RB) for transmission of one packet for each communication link. A communication link quality measure provider is configured to determine a gain-to-interference-plus-noise ratio measure (Gk) for each communication link. A transmit power and transmit rate estimator, connected to the resource block selector and the communication link quality measure provider, is configured to jointly estimate, within the selected set of time-frequency resource blocks, transmit power (Pk) and transmit rate (Rk) of the packets as functions of determined gain-to-interference-plus-noise ratio measures, to at least approximately minimize expected transmitter energy consumption.

Abstract: The present invention provides a method and device for effecting uplink HARQ (hybrid automatic repeat request) on a wireless communications system. A terminal receives HARQ setting data from a base station. If the terminal receives a NAC signal for an initial transmission block, the transmission characteristics of a retransmission block for the initial transmission block are adjusted on the basis of the HARQ setting data.

Abstract: In one aspect, a disclosed method of processing a network packet received by an edge device from a client in a data processing network includes determining a priority category of the network packet when the priority category is indicative of a priority associated with the packet. The method further includes determining a value of a traffic state parameter. The traffic state parameter indicates a level of traffic activity in a backbone network to which the edge device is connected. A traffic policy is then determined that is applicable to the level of traffic activity and the priority category of the network packet. The network packet is then blocked from traversing or permitted to traverse the network packet edge device based on the determined traffic policy. Determining the priority category may include determining a transport protocol port number of the network packet.

Abstract: A system and method for routing multicast packets. A multicast packet is received at an inbound interface on a switch/router. S,G data are obtained from the packet and used to search an OIL table. If the S,G data are found in the OIL table, the packet is forwarded on an outbound interface associated with the S,G data. If the S,G data are not found in the OIL table, the multicast routing table is consulted to obtain a longest match for the packet, and the packet is forwarded on the interface(s) which correspond to the longest match route. The multicast routing table may include a single entry, such that all packets that do not match an entry in the OIL are forwarded on the same outbound interface. The multicast routing table may include multiple entries with different covered ranges of (S,G).

Abstract: The number of required GWs is reduced to suppress the number of facilities by storing MS information on an M2M connection in an external device, and cooperating with the GWs such as mobile GWs in a mobile system in which the M2M connection and a connection other than the M2M connection are mixed together. When an MS migrates to an idle state, the MS stores the MS information in the external device once, and deletes information from an ASN-GW. When the MS migrates from the idle state to an active state, the ASN-GW again draws the MS information from the external device, and again stores the MS information within the device, to thereby enable a communication. If a resource of the active state is short within the device, a migration from the idle state to the active state is enabled with the use of another ASN-GW.

Abstract: The constituency and topology of a dynamic network cluster comprising a plurality of hosts and a plurality of Level 2 network switches is automatically detected and mapped at selected intervals of time to provide current real time topology mappings. Network connections are determined by identifying the MAC addresses of host interfaces of hosts that a part of the cluster and the MAC addresses of the particular host interfaces connected to the switch ports of each switch. Resiliency to account for changes to the cluster between intervals is provided by caching cluster mapping and constituency information, and using the cached information from a previous update round to supplement information detected during a current round.

Abstract: The end of a communication period can be detected reliably and efficiently by a control unit and validity/invalidity of search rules in a search table can be effectively managed. A timer is provided so as to correspond to each entry area of the search table. Then, under control of a timer managing unit, the timer starts a counting operation whenever information is written in a validity management table or a packet in which a communication parameter matches a packet search condition corresponding to information on the validity management table that is set as valid is received. In addition, when a counting time of the timer exceeds a preset time-out time, information indicating the time-out is stored in a time-out management table.

Abstract: A local area network (60) within a residence or other building, including both wired (5) and non-wired segments (53). The wired segments are based on new or existing wires (5a, 5b, 5c, 5d, 5e) in the building, wherein access to the wires is provided by means of outlets (61a, 61d), such as a telephone system, electrical power distribution system, or cable television wiring system. The non-wired segments are based on communication using propagated waves such as radio, sound, or light (e.g. infrared). The wired and non-wired segments interface in the outlet, using a module (50) that serves as mediator between the segments. The module can be integrated into the outlet, partially housed in the outlet, or attached externally to the outlet. Such a network allows for integrated communication of data units (24b) connected by wires and data units (24a, 24d) connected without wires.

Abstract: Various implementations of the disclosed technology relate to selectively filtering inbound communications. An example implementation may send filtered incoming calls directly to an alternate voicemail account based on a list of pre-approved contacts. Moreover, a user notification may not be provided at the time of receiving the incoming call. In another implementation, a response message indicating a user status may automatically be sent back to the sender of the inbound communication. In some implementations, selective filtering of inbound communications may be activated manually by a user, or automatically at a scheduled time, or responsive to a mobile device entering a threshold distance of a location. Discrete logs may be kept for each of selective filtered and allowed inbound communications.

Abstract: The technology provides a frame handler, a controller, and a frame structure design for a new radio communications system that provides backward compatibility with an existing or legacy radio communications system with lower signal bandwidth. Data to be transmitted to the new and legacy radio terminals is processed into a frame using a frame format that is compatible with both the new radio access technology system and the legacy radio access technology system so that both types of radio terminals may receive and extract data from the frame intended for each of those radio terminals. The format allows new and legacy radio terminal communications across the different bandwidths employed by the new and legacy systems.

Abstract: The least movement WSAN topology repair method features an algorithm utilized in wireless sensor actor networks (WSAN) to maintain and restore connectivity following network node failure. The method is distributed throughout the WSAN nodes and relies on nodes' local view about the network. The method uses Path discovery activities in the network to determine the structure of the network topology. Upon failure of a node, the method replaces the faulty node by selecting a neighbor node belonging to the smallest disjointed block. The method is applied further recursively in case the node replacing the faulty node gets disconnected from its children, i.e., neighbors within the block, while imposing no constraints to sustain the path length between any pair of nodes at pre-failure. In this manner, the method minimizes the number of nodes relocated while also reducing message travel distance and complexity.
