  • Patent number: 8830987
    Abstract: An apparatus and a method for IP-based call answering point selection and routing. When an IP-based call is placed to an answering point such as, for example, a Public Safety Answering Point a location for the caller can not be determined using traditional DNIS and ANI based techniques. In the present invention, a geographic location (geolocation) for the caller is determined, from as IP address associated with the caller, using a database. The database comprises information obtained from a plurality of IP location sources (e.g. Skyhook Wireless Inc.'s Loki™, Federal Communications Commission (FCC) mandated WiFi™ hotspot registration data). An answering point is selected from a plurality of answering points as a function of the caller's location. The call is routed to the selected answering point and the caller's location information is provided to that answering point.

  • Patent number: 8817669
    Abstract: A system and method for managing telephone calls is disclosed. The system includes a central controller that receives and processes telephone calls. The identity of a caller is first determined. Based on predetermined settings designated by an end user, a call is directed to one or more telephones of the end user. Preferably, the end user's telephones ring simultaneously. The user may answer any of his/her telephones and choose from among several options of how to handle the call. If the user chooses to answer the call, the call may be transferred to that telephone and the conversation may commence.

  • Patent number: 8817599
    Abstract: A mobile router having a session proxy module is disclosed. The session proxy module may act as a proxy (such as a TCP proxy) for all sessions (e.g., TCP sessions) going through the mobile router. That is, for example, when a local end-user seeks to establish a TCP session from their local end-user device (such as laptop) with a destination (such as a third party server), the session proxy module may (1) terminate the TCP session coming from the local end-user device and (2) establish a TCP (or some other protocol) session on the backhaul interface with the destination. That way, all end-user traffic between the end-user and the destination may be transparently routed through the mobile router.

  • Patent number: 8730977
    Abstract: The invention relates to the field of network communication in a wide area, where a local network of a first type has a sending station that communicates with a receiving station in a local network of a second type. A network of a third type is in between the two networks and provides virtual private networking between the two local networks. The network of the first type supports a fine grained QoS, whereas the network of the third type supports a coarser grained QoS. In one example the network of the first type is RSVP capable and the network of the second type is an MPLS network. The invention resides in a component called RSVP-MPLS proxy that maps the RSVP resource advertisements and reservations within an RSVP-aware customer network to an MPLS network, whereby the receiver side doesn't participate in the RSVP communication process.

  • Patent number: 8699357
    Abstract: Improved techniques are disclosed for detecting instability events in data communications systems that support inter-administrative domain (inter-domain) routing. For example, a technique for detecting an instability event in a communications system supporting inter-administrative domain routing includes the following steps. At an inter-domain router, one or more features are extracted from one or more messages obtained from at least another router in the communications system. The one or more extracted features include a path length feature, a path edit distance feature, or a combination thereof. Then, the inter-domain router detects whether an instability event has occurred in the communications system based on the one or more extracted features such that an action can be effectuated. By way of example, the one or more messages may include one or more border gateway protocol update messages and the inter-domain router may be a border gateway protocol router.

  • Patent number: 8654698
    Abstract: An apparatus receives from a first device a first broadcast message/beacon which comprises an identifier for an enabling station, then uses the identifier to associate with the enabling station to obtain from it a list of at least one license-exempt channel (e.g., TV whitespaces). In one embodiment the apparatus can then join an ad hoc network (IBSS) with the first device and transmit a second beacon which comprises the identifier for the enabling station. If the apparatus hears multiple beacons advertising different IBSSs, it can select to join the first device's ad hoc network over the other(s) based on a service offered or the first device's network being trusted. Various examples are detailed for where in the beacon frame the identifier (e.g., SSID) might be placed. In one example the apparatus and first device are Mode I devices and the enabling station is a Mode II device under (draft) IEEE802.11af.

  • Patent number: 8625456
    Abstract: This document describes tools that withhold a data packet from a switch port despite its destination address. In one embodiment, the tools may receive a port description identifying a set of switch ports. The tools configure the set of ports so that data packets exchanged through the switch by interested entities that would otherwise be forwarded to uninterested entities are instead withheld from the uninterested entities. In another embodiment, the tools may configure a data-packet switch according to a port description identifying a set of ports and a subset of the set of ports. The tools receive a data packet that includes a broadcast destination address on a receive port and then determine, based on the port description, whether the receive port belongs to the subset. If the receive port does not belong to the subset the data packet is withheld from the other ports of the set.

  • Patent number: 8605642
    Abstract: The method and arrangement according to the present invention relates to of scheduling and coding in communication systems utilizing automatic repeat request (ARQ) and/or multihop scheduling and forwarding. According to the inventive method the receiving nodes selectively stores received information, also overheard information, as a priori information and feed back information about their respective stored a priori information to a sending node. The sending node forms composite data packets by jointly encoding and scheduling multiple data packets, which composite data packets are transmitted to receiving nodes. Upon receiving a composite data packet the receiving nodes uses their stored a priori information in the process of extracting data for themselves from the composite data packets.
