  • Patent number: 9756548
    Abstract: A method for optimizing a self organizing network comprising a plurality of cells. The method comprises monitoring performance measurement data indicative of performance of one or more cells in a group of cells in the network, and monitoring trace data indicative of traffic statistics within the cells of the group. The method comprises generating, from the performance management data and the trace data, a plurality of key performance indicators each indicative of performance of an aspect of a cell in the group, and processing the key performance indicators so as to generate a hotspot value indicative of general performance of the cell in the group. The method comprises comparing the hotspot value with a threshold hotspot value, and if the hotspot value is greater than the threshold hotspot value, processing attribute data from the cells in the group so as to generate cause data indicative of a cause associated with the hotspot value exceeding the hotspot threshold value.

  • Patent number: 9602375
    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.

  • Patent number: 9497747
    Abstract: Techniques are provided for aggregating carriers with different carrier configurations. The carriers may include both time division duplex (TDD) and frequency division duplex (FDD) carriers which may be configured such that control information for both carrier types is conveyed by the TDD carrier. In one aspect, an association between a set of subframes, including both TDD and FDD subframes, is determined. The association may operate to distribute control information for the FDD carrier over uplink subframes of the TDD carrier to achieve a load balancing. Alternatively, the association may operate to minimize a hybrid automatic repeat request (HARQ) feedback delay. The TDD carrier may provide resource grants for the aggregated carriers and the association may be used to identify subframes from both carriers which may be scheduled in a given DL subframe.
