  • Patent number: 9660955
    Abstract: Methods, systems and computer program products to communicate using a synthetic Media Access Control (synMAC) addresses are provided. The method includes the step of receiving and storing a first message assigning a first synMAC address. The first synMAC address is distinct from a unique stored Media Access Control (MAC) address. A second message including a second synMAC address is received. The first synMAC address is compared to the stored second synMAC address. The second message is accepted and processed if the first synMAC address is equal to the second synMAC address. In another example, a first device assigns a common synthetic Media Access Control (synMAC) address to multiple devices. The first device then broadcasts a message including the common synMAC address to each of the devices.

  • Patent number: 9648567
    Abstract: A method and apparatus for detecting external interference on an uplink channel of a serving cell in a communication network, such as a Long Term Evolution (LTE) network. Detecting external interference includes identifying neighbor cells of the serving cell and obtaining neighbor cell data associated with each neighbor cell. For each neighbor cell, a processor estimates a noise-rise contribution resulting from communication between the neighbor cell and user equipment based on the neighbor cell data. The processor generates a noise-rise threshold for the serving cell based on the noise-rise contributions estimated for the neighbor cells. Thereafter, the processor obtains a noise-rise measurement at the serving cell and generates an alert indicating external interference when the noise-rise measurement exceeds the noise-rise threshold.

  • Patent number: 9621442
    Abstract: A network monitoring and network congestion analysis can be performed based on a comparison of data packets at multiple different network nodes installed at different locations on a communication path. A downstream network node may be installed at a user location while an upstream network may be installed at an access router further up the network. A network congestion analyzer may receive data packet information including timestamps from both network nodes, and may compare the data packet information to group the data packets into application flows and match the corresponding packets from the different network nodes. Based on the data packet matching, the network congestion analyzer may calculate packet loss, packet delay, packet delay variation, and perform other network congestion analysis techniques for the application flows corresponding to a user's various devices and the applications executing on those devices.

  • Patent number: 9596678
    Abstract: Provided are a base station, whereby the erroneous detection of control information can be reduced, thereby preventing the degradation of the system throughput. A base station (100) maps a downstream allocation control information unit, which is addressed to a terminal (200), to a first resource region, which can be used for any of a downstream control channel region and a downstream data channel region, or to a second resource region, which can be used only for the downstream control channel, so as to transmit the downstream allocation control information unit. In the base station (100), a control unit (102) establishes a scale of the PDCCH region, and a transmission region establishing unit (131) establishes, on the basis of a scale value established by the control unit (102), a mapping region to which the DCI is mapped within the R-PDCCH region and the PDCCH region.

  • Patent number: 9591662
    Abstract: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.

  • Patent number: 9548914
    Abstract: The invention measures the rates of a whole population of existing lines together with a line characteristic, such as capacitance, that can be measured prior to provisioning. Using these measures, a rating we refer to as a “quality figure” is generated for each distribution point by looking at the rate of the lines running through that distribution point, and comparing those rates to the rates of other lines having the same line characteristic across the whole population of lines. Distribution points that have lines operating better (faster) than the average for their given line characteristic will have higher quality figures. To estimate the rate of a new line, the quality figure of the distribution point that the new line passes through is used in conjunction with the measured line characteristic as a look up on the whole population of lines.
