Abstract: Methods and systems are described that are suitable for channelization, in particular, but not limited to, the IEEE 80216.m telecommunications standard. For a time-frequency resource, physical sub-carriers for each of one or more zones in the time-frequency resource are assigned to one or more zones having a respective type of transmission. At least one zone is allocated for a type of transmission using localized sub-carriers. The physical sub-carriers assigned to each zone are permuted to map to logical sub-carriers. Groups of resource blocks are formed, in which each resource block includes at least one logical sub-carrier for each of the one or more zones. The information defining the groups of resource blocks for each of the one or more zones can then be transmitted to a user. The information may be in the form of a zone configuration index.

Abstract: A method includes receiving at a network device, an identifier from a vehicle routing device. The vehicle routing device is configured to identify packet data flows based on an application running on a vehicle client device. The packet data flows are flowing over a communication link between the vehicle routing device and the vehicle client device. The method includes identifying each packet of each flow according to the application that sends or receives packets related to each of the packet data flows, determining an extended header for the one or more packet data flows based on an Internet protocol version 6 (IPv6) extension header and a RADIUS vendor specific attributes (VSA) structure, and transmitting, by the vehicle routing device, to the network device, the extended header and the one or more packet data flows.

Abstract: Embodiments of the invention provide a device and a frame structure for powerline communications. The header may comprise two parts that are separately encoded. A common header segment is encoded alone, and an embedded header segment is encoded with payload data.

Abstract: A method, system, and medium are provide for dynamically allocating frequency bands transmitted by a base station to a user device to optimize signal strength at the device. A distance from the base station to the user device is determined, and if the distance is greater than a distance threshold, a lower-frequency band is allocated to the device. If the distance is less than the distance threshold, a penetration loss factor for the device is calculated. If the penetration loss factor is greater than a penetration loss threshold, a lower-frequency band is allocated to the device, and if the penetration loss factor is less than the penetration loss threshold, a higher-frequency band is allocated to the device.

Abstract: The invention provides a system and method for repairing corrupt security information. At a serving node in a telecommunications network, security capabilities of a terminal are received when the terminal registers with the serving node. The received security capabilities are stored. A path switch request message is received from a target base station following an X2 handover request sent from a source base station to the target base station for handover of the terminal, the path switch request including the security capabilities of the terminal. The serving node determines whether the security capabilities of the terminal stored in the storage medium should be sent to the target base station. If so, the serving node sends the stored security capabilities of the terminal to the target base station for use in reselecting security algorithms to be used in communications between the target base station and terminal following the handover.

Abstract: A distributed scheduling scheme for D2D communications is described in which D2D transmitter terminals send transmit requests and D2D receiver terminals respond with bandwidth grant messages if certain interference criteria are met. The described scheme may include a technique for more efficiently scheduling D2D links by having D2D receivers base their decisions as to whether to send a bandwidth grant message on whether or not a higher priority D2D receiver has transmitted a bandwidth grant message.

Abstract: An apparatus and a method for transmitting a control signal for determining a keep alive status of a counterpart node in a broadband communication network are provided. When a period for determining a keep alive status of the counterpart node to which a data is connected arrives, whether traffic is received from the counterpart node is determined. If it is determined that the traffic is received from the counterpart node, the keep alive status of the counterpart node is determined using the traffic received from the counterpart node. If it is determined that the traffic is not received from the counterpart node, a request signal for determining the keep alive status of the counterpart node is transmitted to the counterpart node.

Abstract: A technique for routing one or more service tunnels in a telecommunications backhaul network (110) is provided. The telecommunications backhaul network has a first routing path (132) and a second routing path (134). As to a method aspect of the technique, data of the one or more service tunnels is transmitted on the first routing path (132). A reduction in transmission capacity is detected on the first routing path (134) by means of a first routing path condition. The first routing path condition indicates a state of the first routing path (132). A second routing path condition is determined indicating a state of the second routing path (134) in response to the detected reduction in transmission capacity on the first routing path (132). It is decided upon rerouting one or more of the service tunnels from the first routing path (132) to the second routing path (132) based on both the first routing path condition and the second routing path condition.

Abstract: Some embodiments provide a method for a first host machine that hosts a virtual machine connected to a particular logical network. The method receives a command to test connectivity between the first host machine and a set of at least one additional host machine that also host virtual machines on the particular logical network. At the first host machine, the method generates a packet for sending to the set of additional host machines in order to test the connectivity. The method appends to the generated packet (i) information that identifies the particular logical network and (ii) a flag indicating that the packet is for connectivity testing. The method encapsulates the generated packet with tunnel endpoint addresses, including a tunnel endpoint located at the first host machine. The method sends the encapsulated packet from the first host machine to the set of additional host machines according to the tunnel encapsulation.
