  • Patent number: 9491203
    Abstract: A method of and servers for establishing a signalling path (20) for a communication session between a calling party (2) and a called party (11) in an Internet Protocol, IP, communications network. The signalling path (20) between the calling party (2) and the called party (11) is established via at least one subscriber registrar server (32) and at least one application server (30) invoking at least one service for the communication session. Dependent on the type of service, if capable for taking over control of the communication session, the at least one subscriber registrar server (32) may be at least partly released from the signalling path (20) for the at least one invoked service.

  • Patent number: 9467942
    Abstract: A wireless communication network system includes a first wireless communication device; and second wireless communication devices. The first wireless communication device selects a master unit from among the second wireless communication devices, on the basis of reception quality and storage battery remaining levels, and sends, to the selected master unit, a master unit request and a storage battery remaining level threshold for the master unit. The selected second wireless communication device operates as the master unit in accordance with the master unit request, and monitors the storage battery remaining level of the selected second wireless communication device on the basis of the storage battery remaining level threshold. When the storage battery remaining level of the selected second wireless communication device does not match the storage battery remaining level threshold, the selected second wireless communication device sends a master unit change request to the first wireless communication device.

  • Patent number: 9462601
    Abstract: A system and method of scheduling communication in a wireless communication network are provided. A scheduling scheme comprising a first subframe and a second subframe can be determined to communicate data between a first access node and first wireless devices, and a second access node and second wireless devices. A resource request can be received from one of the first wireless devices. An interference indication can be determined based on the resource request. The first access node can be instructed to communicate with the first wireless devices during the first subframe and the one of the first wireless devices can be instructed to transmit data to the first access node during the second subframe when the interference indication meets an interference criteria. The second access node can be instructed to transmit data addressed to at least one of the second wireless devices during the second subframe.

  • Patent number: 9444559
    Abstract: IP2 calibration efficiency can be improved by passing the calibration signal through the transceiver's duplexer instead of inserting the calibration signal directly onto transceivers receive circuit. Passing the calibration signal through the duplexer may reduce IP2 calibration periods for transceivers having less-permeable duplexers, or duplexers that provide better than average separation between the RX and TX circuits. IP2 calibration inefficiencies can also be reduced by using a binary-like search when computing the in-phase and quadrature-phase path correction coefficients of the IP2 correction code.

  • Patent number: 9438503
    Abstract: The disclosure relates to test-capable pluggable transceivers and network systems and methods using such transceivers. A central test server generates a test request and communicates to a mediation sub-system, which uses a common management protocol to communicate with a plurality of transceivers in the network. The mediation sub-system translates the test request into sub-tests and generates sequences of test-control commands for executing by specific transceivers to configure test logic deployed within the transceivers for testing designated network services, to generate test frames, and/or to process received frames to collect test results.

  • Patent number: 9432285
    Abstract: A communications network is operated by providing a plurality of redundant links between a first network node and a second network node. A first identifier is associated with a first one of the plurality of redundant links and a second identifier is associated with a second one of the plurality of redundant links. The first and second identifiers are associated with the regulatory constraint. Traffic that is marked with the first identifier is routed to the first one of the plurality of redundant links and traffic that is marked with the second identifier is routed to the second one of the plurality of redundant links so that operation of the communications network is in compliance with the regulatory constraint.

  • Patent number: 9401785
    Abstract: Disclosed are a coordinated set selecting method and device, which are applicable to a wireless communication system. The coordinated set selecting method comprises the following steps: determining a transmission manner adopted by a wireless communication system, the transmission manner being joint processing or coordinated scheduling/beamforming; and, directed to the transmission manner adopted by the wireless communication system, selecting a coordinated set according to a coordinated set selecting mechanism adapting to the transmission manner. According to the technical solution of the present invention, by considering transmission characteristics of different transmission manners, a reasonable coordinated set is selected to perform coordinated multi-point transmission.

  • Patent number: 9363196
    Abstract: The present invention is provided with: a data-driven processor comprising at least a firing control which determines whether or not firing conditions have been met by determining whether or not all packets necessary for instruction execution have been received when a packet that convey a part of partitioned data to be processed has been input, and a data processing unit for performing processing corresponding to the packets transmitted from the firing control if the firing conditions have been met; a power supply circuit for supplying power to the data-driven processor; and overload avoidance means for refusing input of the packets to the data-driven processor, if a determination has been made that a data processing load in the data-driven processor may reach an overloaded state in which the data processing may stall, on the basis of current consumption in the data-driven processor. Accordingly, power consumption in a networking system is reduced.

  • Patent number: 9294958
    Abstract: The present disclosure presents a method and apparatus for dynamically configuring a cell update message at a user equipment (UE). For example, the method may include determining that a size of the cell update message at the UE is above a threshold value after a “measured results on random access channel (RACH)” information element (IE) is excluded from the cell update message. Furthermore, such an example method may include removing one or more IEs from the cell update message until the size of the cell update message is at or below the threshold value. As such, dynamic configuration of a cell update message at a UE is achieved.

  • Patent number: 9066320
    Abstract: A method to facilitate late entry of a late entrant node into an ad-hoc radio network involves accessing from a memory at the late entrant node an initial frequency hopping sequence for the ad-hoc radio network. The late entrant node uses at least the initial frequency hopping sequence to determine a first frequency to monitor during a communication epoch corresponding to one of the frequency hops. The late entrant node thereafter monitors the first frequency to detect the presence of a beacon signal transmitted by a participating node of the network. Subsequently, the late entrant node determines a second frequency included in the current hopping sequence of the network based on information contained in the beacon signal.
