  • Patent number: 10325055
    Abstract: This application discloses a computing system configured to determine a timing window for reception of a signal propagated through a victim channel in a circuit design, generate an aggressor window bump for each noise bump capable of being induced on the victim channel by one or more aggressor channels, determine a delta delay corresponding to the timing window for the signal propagated through the victim channel based, at least in part, on one or more of the aggressor window bump, and utilize the delta delay corresponding to the timing window for the signal to determine whether the victim channel operates within a timing constraint associated with the circuit design.

  • Patent number: 10021725
    Abstract: Systems and methods are provided that allow inter-working between communication networks for the delivery of service to mobile nodes. A gateway is provided that communicates with a femto cell to extend service to an area that otherwise does not receive coverage from a service provider. The femto cell is a small scale base station used to provide coverage over a small area (such as a home or business), and connect to a home or enterprise network. The femto cell provides service for a mobile node and a gateway permits communication over a broadband network. The gateway integrates the mobile nodes connecting via a femto cell into the service provider's network. The gateway also allows provisioning of services and applications, control of service levels, and provides seamless handoffs to marco base stations and other types of access technologies such as Wi-Fi.

  • Patent number: 9801094
    Abstract: This disclosure relates to a system and method for dynamically managing load on network devices in a distributed manner. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has exponentially increased. Upgrading the existing network to accommodate increased data traffic is neither desirable nor practical. One way to accommodate increased data traffic is by utilizing network resources more efficiently. This disclosure provides systems and methods for efficiently utilizing network resources by dynamically configuring the network in a distributed manner based on real-time load information.

  • Patent number: 8837382
    Abstract: Systems and methods for enhancing broadcast/multicast services in telecommunication networks are disclosed. A multicast router is provided between a network node, such as an SGSN or GGSN, and a radio access network. A multicast transport address can be provided to send packet data from network devices to the radio network in a multicast fashion. The multicast transport address works with multicast equipment, such as multicast routers, to reduce the burdens of sending data in a broadcast or multicast fashion to mobile nodes.

  • Patent number: 8693367
    Abstract: This disclosure relates to a system and method for offloading selected data to an alternate communication network. The offloading provides another route for selected packet traffic that can relieve the burden on a mobile operator's network, such as the backhaul and core networks. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has exponentially increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. A offload gateway is provided that inspects packets and determines those packets to offload to an alternate network as well as providing mobility management to allow for seamless handoffs and gateway relocations.
