Abstract: In a node device 1 in a communication network, an FID management table 5 stores an FID for unique identification of a frame and the information about a destination node of the frame, and a weighting table 7 stores weighting information about another node as a destination for relay of the frame for each final destination node of the frame. When a frame transmitted to a local node is received, and if the FID of the received frame is stored in the FID management table 5, the data about the destination node associated with the FID is updated. If the FID of the frame received from the frame reception device is not stored in the FID management table 5, the FID management table 5 corresponding to the destination node of the frame is referred to, and another node as a destination for relay of the frame is determined.

Abstract: The invention relates to a method for controlling the maximum bit rate for a bearer used for data transmission over a packet-switched network using a specified access point for a group of mobile entities. A PDN gateway enforces the maximum bit rate for the group, the APN group AMBR. This is possible as all mobile entities belonging to said group are connected to the same PDN gateway for a certain access point name APN. This is obtained by providing a PDN gateway information into an update location acknowledgement message sent from the HSS to the MME.

Abstract: The present invention relates a voice communication method between a plurality of users sharing the same transmission band. The resource is accessed by time division under the supervision of a control node. During a polling step, any user wishing to speak transmits (210) a request to the control node. The control node allocates (220) transmission frames to the requesting users or merely to some of these users. Users allocated a transmission frame can then transmit (230) a voice packet to the respectively allocated frames thereof. The transmission frames are interleaved temporally so as to give the impression of full-duplex communication during voice reproduction.

Abstract: A switch includes network ports and a network processor with a fabric interface that provides SerDes (Serializer/Deserializer) channels. The network processor divides each packet received over the network ports into cells and distributes the cells across the SerDes channels. Fabric ports of the switch communicate with the fabric interface to transmit cells to and receive cells from the fabric interface. The switch is selectively configurable as a standalone switch by connecting each fabric port of the switch to another of the fabric ports of the switch, as a member of a switch stack by connecting each fabric port of the switch to a different other switch through one fabric port of that other switch, or as a member of a distributed fabric system by connecting each fabric port of the switch to a different scaled-out fabric coupler (SFC) chassis by an SFC fabric port of that SFC chassis.

Abstract: Provided is a compact base station apparatus (HeNB) whereby frame timing can precisely be synchronized between HeNB and MeNB, thereby suppressing the interference in an upstream channel. In HeNB (100), which forms a cell smaller than a cell formed by MeNB, frame timing detecting unit (111) detects, based on a sync signal received from MeNB, the frame timing of MeNB; a control unit (116) uses the frame timing of MeNB to set the frame timing of a downstream channel in HeNB (100); a transmission RF unit (118) transmits, in accordance with the frame timing of the downstream channel in HeNB (100), a preamble to MeNB; and a TA command extracting unit (114) acquires, from a response signal responsive to the preamble, information indicating a difference in frame timing between MeNB and HeNB (100).

Abstract: Some implementations of the present invention provide mechanisms for gating the transmission of FIN and other short overhead messages of the like in order to improve spectral efficiency. In some implementations spectral efficiency is improved by reducing the number of air-link connections established to merely transmit FIN and other short overhead messages of the like. In one implementation FIN messages are buffered in a queue and transmitted when an air-link connection is established to transmit higher value messages. In one implementation FIN messages are buffered and transmitted when the contents of the buffer breach a threshold that justifies the establishment of an air-link connection to transmit the contents of the buffer.

Abstract: A data communication network includes a client device and multiple aggregation devices coupled to each other and the client via links within a link aggregation group (“LAG”) across the aggregation devices. The aggregation devices appear to the client as a single device coupled thereto, and operate in conjunction with each other by assigning at least one different identifier to each of the plurality of separate aggregation devices and storing information including the identifiers to association tables located on each of the aggregation devices. The multiple aggregation devices can be separate switches, and the LAG can include multiple ports across the switches, with a different identifier being assigned to each of the ports in the LAG. A virtual link trunk interface can couple aggregation devices, which can reconfigure communication paths thereacross with respect to the client device using the identifiers in the stored association tables when a LAG link fails.

Abstract: A communication line is installed in a network by automating a design phase and a configuration phase for the service and by automating failure recovery in either of the phases. In the design phase, an optimal route for the communication line is found, and the network components are provisioned and assigned. If the assigned network components are not available or can not be validated, the components causing the failure are marked, and the design phase is retried without the marked components. After the design phase, the configuration phase begins. The circuit design is tested against actual network components. If the test is passed, the actual network is configured according to the circuit design and the circuit is activated. If there is a network component failure during the configuration phase, the good route elements in the design are released while the failed network components are marked. The design phase is retried.
