  • Patent number: 8315261
    Abstract: Techniques for processing an IP packet at a router that supports SS7 signaling include receiving IP routing data that associates a network link and a destination IP address for a node in a signaling network that includes a plurality of signaling nodes. When an ingress IP data packet is received, it is determined whether conditions are satisfied for locally processing an SS7 payload within the ingress IP data packet. If it is determined that conditions are satisfied for locally processing the SS7 payload, then the SS7 payload is processed locally, i.e., without sending the SS7 payload over a network link to a different node in the signaling network. If it is determined that conditions are not satisfied for locally processing the SS7 payload, then the ingress IP data packet is routed normally. These techniques allow reduced numbers of expensive STP devices and expanded routing options in a signaling network.

In a method for providing a data service to an MS through different wireless networks, the MS measures channel qualities of at least one accessible wireless network and reports the measured channel qualities to an Internet Protocol (IP) packet controller. The IP packet controller selects wireless networks for data transmission on the basis of the reported channel qualities, distributes data destined for the MS, and transmits the distributed data to the selected wireless networks. The selected wireless networks receive the data from the IP packet controller and transmits the received data to the MS. The MS combines and interprets the data received from the selected wireless networks. Accordingly, it is possible to provide a seamless data service to the MS in service environments with a mixture of different wireless communication systems.

  • Patent number: 8259676
    Abstract: Various security mechanisms may be used independently, or in combination with one another, to authenticate the identity of a node during the Mobile IP registration process. First, an Access Point receiving a packet from a node verifies that the source MAC address identified in the packet is in the Access Point's client association table. In addition, as a second mechanism, the Access Point ensures that a one-to-one mapping exists for the source MAC address and source IP address identified in the packet in a mapping table maintained by the Access Point. As a third mechanism, a binding is not modified in the mobility binding table maintained by the Home Agent unless there is a one-to-one mapping in the mobility binding table between the source MAC address and the source IP address. Similarly, the Foreign Agent may also maintain a mapping between the source IP address and the source MAC address in its visitor table to ensure a one-to-one mapping between a source IP address and the associated MAC address.

  • Patent number: 8074275
    Abstract: A method of preventing network denial of service attacks by early discard of out-of-order segments comprises creating a reassembly queue for a connection between a first network node and a second network node, wherein the connection has been established based on a transport-layer network protocol, the reassembly queue having a size based on a buffer size of an input interface with which the connection is associated. As out-of-order data segments arrive on the connection, and before other processing of the segments, whether the reassembly queue is full is determined, and the out-of-order segments are discarded if the reassembly queue is full. The size of the reassembly queue is automatically changed in response to one or more changes in any of network conditions and device resources.

  • Patent number: 8068500
    Abstract: A conventional node 3 divides an IP packet into data fragments and prepares a packet for RAN 9 transmission. There has been a problem that, since a RAN 6 cannot identify an IP packet unit, affinity is low relative to an IP network 1 that serves as a core. A node 3 prepares A10 packets by dividing an IP packet, and adds, to each A10 packet, a concatenation flag that indicates information stored in the A10 packet is the head or the tail of the IP packet. A base station 5 and a packet control device 4 employ the concatenation flag to control transmission for each IP packet unit. For example, a packet control device 4 employs a concatenation flag to discard information for a series of A10 packets received by the node, including information that constitutes the same IP packet.

  • Patent number: 8014383
    Abstract: A communication system capable of improving telephone communication service by effectively integrating communications with IP phones and with mobile phones. A connection controller controls a connection interface with a mobile phone and obtains the phone number of the mobile phone being connected thereto. A connect information transmitter transmits connect information including identification information and the phone number. A connect information manager stores and manages the received connect information. When a calling IP phone sends a request to call the mobile phone, a communication controller determines based on the connect information whether the mobile phone is connected to a receiving IP phone. If yes, the communication controller makes a call to the receiving IP phone to establish communication between the calling and receiving IP phones.

  • Patent number: 8014405
    Abstract: An Asynchronous Transfer Mode (ATM) signal is phase modulated based on an Internet Protocol (IP) signal to form a combined ATM/IP signal. The ATM signal is phase modulated without exceeding a specified tolerance of symbol period of the ATM signal. The combined ATM/IP signal is communicated on a passive optical network to multiple receiving locations. An ATM stream specific to a receiving location can be extracted from the combined ATM/IP signal by an existing ATM-based optical network termination (ONT). An IP stream can be extracted at a receiving location by phase demodulating the combined ATM/IP signal.
