  • Publication number: 20160029290
    Abstract: In embodiments of mesh network commissioning, a commissioning device of a mesh network can determine steering data for the mesh network, where the steering data is an indication of a device identifier associated with a device that is allowed to join the mesh network. The commissioning device can then propagate the steering data from the commissioning device for the mesh network to one or more routers in the mesh network, and the steering data indicates that a commissioner is active on the mesh network. The commissioning device propagating the steering data enables the one or more routers to transmit the steering data in a beacon message, and the steering data is effective to enable the device associated with the device identifier to identify that the device is allowed to join the mesh network.

  • Patent number: 9232479
    Abstract: Power savings and interference reduction for multimode devices (e.g., base stations and relay nodes) is disclosed. In some embodiments, power savings and interference reduction for multimode devices includes selecting a power state of the multimode device selected from a plurality of power states, in which the multimode device is in a first power state (e.g., an active or serving power state), and in which the selected power state is a second power state (e.g., a reduced power state), and transitioning the multimode device from the first power state to the second power state.

  • Publication number: 20150373691
    Abstract: In embodiments of mesh network commissioning, a commissioning device of a mesh network can determine steering data for the mesh network, where the steering data includes an indication of a device identifier associated with a device that is allowed to join the mesh network, and the indication is represented as a set of values in a Bloom filter that represent the device identifier. The commissioning device can then propagate the steering data from the commissioning device for the mesh network to one or more routers in the mesh network. Propagating the steering data enables the routers to transmit the steering data in a beacon message, where the steering data enables the device associated with the device identifier to compare the set of values in the Bloom filter to a second set of values determined at the device to identify that the device is allowed to join the mesh network.

  • Patent number: 9094334
    Abstract: A solution for virtual router redundancy for server virtualization includes, at a network device configured as a backup router of a virtual router, examining a packet stored in a memory of the network device. Responsive to the examining, the network device determines whether to forward the packet via a network towards a destination or to send the packet via the network to a master router of the virtual router for forwarding of the packet, by the master router, towards the destination.

  • Publication number: 20150173083
    Abstract: Various techniques are disclosed for wireless communications for providing a methodology and algorithm(s) to manage resources and schedule users in a coordinated way among a group of base stations, such as Femtocells, Picocells, self-organized Basestations, Access Points (APs) or mesh network nodes, or among the basestations in a two tiered networks, to improve the performance for individual user, individual Basestation (BTS), the overall systems or all of above.

  • Publication number: 20150105065
    Abstract: Apparatus and methods for synchronizing a network element (e.g. access points, femtocells, etc.) to a master network (such as a cellular network) to provide accurate frequency and/or time references for their internal systems. In one embodiment, the network element utilizes a dedicated receiver (or transceiver) to receive timing information from the master network. The implementation of the dedicated receiver is advantageous for cost and simplicity reasons. Furthermore, the timing or frequency information, as received from the master network, is used to correct the network element's internal timing. In addition, the network element's internal timing can operate in open-loop mode, if no master network can be found, thereby allowing for the device to continue providing service to network users. Additionally, a dedicated receiver can also receive information (e.g. location, SID, NID, SSID, etc.

  • Publication number: 20140355481
    Abstract: LTE and HSPA/UMTS deployments are trending towards high density, heterogeneous and ad-hoc deployments. These deployments can be managed through Self-Organizing Network (SON) schemas. Enabling SON generally involves the introduction of new software and/or hardware entities into the network that can interact with existing base station and network entities (e.g., Enhanced Packet Core, Element Management System, and/or other network entities). In one embodiment, these interactions include the development and deployment of interfaces (e.g., APIs) and protocols between the SON entities and various network entities. For example, data collected on either side of an interface or protocol can be post-processed before consumption (e.g., for both data integrity purposes as well as bandwidth reduction purposes).

  • Patent number: 8804649
    Abstract: Self-optimization in heterogeneous networks techniques are provided. In autonomous mode, certain self-optimization criteria are used to set up one or more targets with same or different priorities. The cells in a defined area of a HetNet autonomously adjust certain radio resources (e.g., power, time, frequency, and/or spatial resources (e.g. antenna, location)) in order to achieve or to be close to the targets such that the self-optimization criteria are met. In a coordinated mode, certain self-optimization criteria are used to define one or more cost functions with same or different priorities. The cells or a subset of users in the cells in a defined area of a HetNet search for the optimal solution for the cost functions by coordinating certain radio resources.

  • Patent number: 8737310
    Abstract: In wireless system, a group of Base station (BTSs) with smaller footprints have the capability to communicate with each other as well as with the BTSs with relatively larger footprints via wireless air-interfaces. One of such example is coordinated cell systems. A coordinated cell system comprises a group of coordinated cell base stations that have the capability to communicate with each other as well as with relevant macro cell or Pico cell base stations via wireless air-interfaces. Each coordinated cell BTS consists of an over the air control unit in addition to the conventional coordinated cell BTS system. A set of protocols in the form of messages and database are also defined to enable the networking capability. This enables enhancement in performing a variety of tasks by coordinated cell systems, including interference management and coordination, registration and authentication, quality of service coordination, installation and maintenance, location services, etc.

  • Patent number: 8734827
    Abstract: A bioengineered IVD for disc replacement has been developed that has mechanical and structural support characteristics similar to those of native IVD. Extracellular matrix (ECM) provides support to living cell components and interacts with the living cellular components during the fabrication process without introducing toxicity. The composition can be produced from both natural or synthetic source but preferably natural and induced to self-assemble or reconstitute into its solid form under conditions that are mild enough to support cellular survival and growth. The cells induce a volume change of the structures, leading to changes in dimension, ECM density, cell density, mechanical property and stability, etc. The extent of the change in volume of the composition can be precisely controlled by factors such as the density of the ECM, the density of the living cells, the timing for interaction and the serum concentration. Increased structural support is provided by crosslinking.
