  • Patent number: 9871568
    Abstract: Techniques are described herein for fast and efficient discovery of small cells by user equipment (“UE”) in a wireless telecommunications network. The small cells may operate at a high frequency band (“HFB”), which may correspond to higher frequencies than other cells (e.g., base stations, such as evolved Node Bs (“eNBs”)) of the network. The UE may receive assistance information, which may include polling channel configurations, beamforming weights, carrier frequencies, cell identifiers of small cells, and/or other information. The UE may use the assistance information when outputting (either omnidirectionally, pseudo-omnidirectionally, or directionally) a polling sequence, in order to detect the small cells.

  • Patent number: 9847954
    Abstract: The subject matter disclosed herein relates to a frame switch of an AFDX network in which the data acquisition application is decentralized. When the switch has to acquire the data transmitted on a virtual link, the switching table contains, apart from the input port and the output port (s) taken by this link, an ID representing the MAC address of the switch. The frames of this link are then not only switched but also transmitted to the network interface of the switch and processed by a dedicated application (DDA), hosted inside the switch. This application can be interrogated by a remote server and transfer the data that it has stored locally.

  • Patent number: 9832122
    Abstract: Apparatus, systems and methods may be used to monitor data flows and to select and track particularly large data flows. A method of tracking data flows and identifying large-data (“elephant”) flows comprises extracting fields from a packet of data to construct a flow key, computing a hash value on the flow key to provide a hashed flow signature, entering and/or comparing the hashed flow signature with entries in a flow hash table. Each hash table entry includes a byte count for a respective flow. When the byte count for a flow exceeds a threshold value, the flow is added to a large-data flow (“elephant”) table and the flow is then tracked in the large-data flow table.

  • Patent number: 9813901
    Abstract: Disclosed is a technique for performing flexible service-level access control in real-time while suppressing occurrence of signaling. According to the technique, a network entity (AAA server 10) configured to perform access control sets correspondences between addresses of a communication terminal (UE) 40 and respective service contents of services that the communication terminal 40 receives, and notifies the communication terminal of the correspondences. Thus, the communication terminal is able to know the service contents corresponding to the addresses that the communication terminal uses. In a case where a service content of a service that the communication terminal receives is changed, the address used by the communication terminal is changed to an address corresponding to the changed service content. As a result, from the changed address, the communication terminal is able to know that the service content has been changed and to know the changed service content.

  • Patent number: 9788348
    Abstract: A wireless local area network (WLAN) provides wireless service to a collective comprising multiple remote units (RUs) by use of a collective association identifier (AID) assigned to, and shared by, the multiple RUs. The WLAN then uses the collective association identifier AID to identify transmissions of common data to the multiple remote units. Furthermore, the WLAN provides for a serving AP to store, for the collective as a whole, shared data rather than individually storing such data in association with each remote unit (RU) in the collective. The WLAN further provides for RUs to establish a link with their serving AP in order to exchange data sourced by, or intended for, their associated non-RF service provider, and for the AP then to establish a separate AP-to-service provider link to exchange the data, rather than the RU being required to establish an end-to-end link with the service provider.

  • Patent number: 9787562
    Abstract: The invention relates to the technical field of domestic networks. A domestic network based on the present UPnp-Standard allows AV connections to be set up between two network subscriber stations—Network connections such as these are set up and managed under the control of a network station which is in the form of a control point. In this case, the UPnP-Standard allows the network station which is the form of a control point to log off the network after setting up an AV connection, and thus to be inactive while the AV connection that has been set up is in existence. This results in the problem that an AV connection which has been set up unnecessarily remains in existence even after the desired AV data stream has been transmitted, so that further connection requests for such stations must be answered with a rejection.

  • Patent number: 9730125
    Abstract: A technique for providing per station control of multiple stations in a wireless network across multiple access points. A look-up table that assigns a station connected to the access point and at least one communication parameter to each of a plurality of persistent, uniquely-assigned BSSIDs (Basic Service Set Identifiers) is stored. An access point responds to messages addressed one of the plurality of persistent, uniquely-assigned BSSIDs and ignores messages addressed to other BSSIDs. Persistence of the BSSID allows the controller to maintain individual control over each station after moving to a second access point of the plurality of access points. A frame comprising the plurality of BSSIDs corresponding to each connected station aggregated into the frame is generated. The frame is transmitted to the plurality of stations.
