  • Patent number: 9820295
    Abstract: Coordination information for controlling base-station-to-base-station interference is transmitted from one radio network node (900) (e.g., an LTE eNodeB) to another, using certain parts of the TDD subframe. One example method, as might be implemented in a radio network node (900) such as an LTE eNodeB, includes the generating (1010) of a TDD coordination signal and the transmitting (1020) of the TDD coordination signal to one or more other radio network nodes. In some embodiments, the coordination signal is transmitted in a guard period of a special subframe at the target node. In others, the coordination signal is transmitted in another interval during which the receiving node is not transmitting, such as in uplink subframe for the receiving node, an uplink portion of a special subframe at the receiving node, or in a downlink subframe or downlink portion of a special subframe during which the receiving node is not transmitting.

  • Patent number: 9813375
    Abstract: Upon receipt of a packet addressed to a virtual IP address assigned to each first device from a second device outside a base network, a processor identifies a base relay apparatus that accommodates the first device, to which the virtual IP address is assigned, on the basis of the virtual address and a protocol type of the received packet, and also identifies a reception port number of the identified base relay apparatus, which corresponds to a combination of the virtual IP address and the protocol type of the received packet, from among reception port numbers each assigned to a combination of the first device accommodated to identify a transfer destination, and a protocol type. Then, the processor relays the received packet to the identified reception port number of the identified base relay apparatus.

  • Patent number: 9781037
    Abstract: Systems, methods, and computer-readable media provide for collection of statistics relating to network traffic between virtual machines (VMs) in a network. In an example embodiment, a virtual switch hosted on a physical server provides network address information of VMs deployed on the physical server to a virtual switch controller. The controller collects this network address information from each virtual switch under its control, and distributes the aggregate address information to each switch. In this manner, the controller and each switch within the controller's domain can learn the network address information of each VM deployed on physical servers hosting switches under the controller's control. Each virtual switch can determine a classification of a frame passing through the switch (e.g., intra-server, inter-server and intra-domain, or inter-domain traffic), and statistics relating to the traffic.

  • Patent number: 9769080
    Abstract: A switch includes a reserved pool of buffers in a shared memory. The reserved pool of buffers is reserved for exclusive use by an egress port. The switch includes pool select logic which selects a free buffer from the reserved pool for storing data received from an ingress port to be forwarded to the egress port. The shared memory also includes a shared pool of buffers. The shared pool of buffers is shared by a plurality of egress ports. The pool select logic selects a free buffer in the shared pool upon detecting no free buffer in the reserved pool. The shared memory may also include a multicast pool of buffers. The multicast pool of buffers is shared by a plurality of egress ports. The pool select logic selects a free buffer in the multicast pool upon detecting an IP Multicast data packet received from an ingress port.

  • Patent number: 9762359
    Abstract: There is provided a method, a user equipment and a base station that is capable of enhancing network throughput by efficiently transmitting E-DCH HARQ Acknowledgement Indicator Channel (E-HICH) information in the radio network. The method comprises combining previous E-HICH information with current E-HICH information when a transmission interval of the previous E-HICH information fully overlaps with a compressed mode gap, and transmitting the combined E-HICH information in a transmission interval of the current E-HICH information. The UE is configured to transmit uplink data even if it is determined that the E-HICH information of the uplink data will not be received before a next uplink transmission interval. Both the previous E-HICH information and the current E-HICH information will be received in the transmission interval of the current E-HICH information. Therefore, the network throughput is effectively enhanced.

  • Patent number: 9742533
    Abstract: Techniques for minimizing the loss of radio signals transmitted on and/or received from serving cells in a multi-carrier system by selectively adapting the time instance at which a wireless terminal: (1) changes its radio frequency (RF) bandwidth or activates a second RF chain or any additional RF chain for measuring on one or more secondary serving cells, and/or (2) performs setup or release of one or more secondary serving cells. An example method, implemented in a radio network node, comprises determining (510) a scheduling instance during which a wireless terminal is expected to be scheduled on at least one cell; and, determining (520) a timing at which to send a setup or release command for at least one secondary cell such that the requested set up or release procedure does not coincide with the scheduling instance.
