摘要： 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.

摘要： One embodiment of the present invention provides a system that speeds up timing analysis by reusing delays computed for isomorphic subcircuit. During operation, the system receives a circuit block to be analyzed, wherein the circuit block is in the form of a netlist. The system then subdivides the circuit block into a set of subcircuits. The subcircuits are then partitioned into equivalence classes, which contain subcircuits which are topologically isomorphic to each other. Next, the system performs a timing analysis by tracing paths through a timing graph for the circuit block. During this timing analysis, whenever a delay is required for a subcircuit, the system determines if a corresponding delay has been already computed for the equivalence class associated with the subcircuit. If so, the system reuses the delay. If not, the system computes the delay for the subcircuit, and then associates the computed delay with the equivalence class so that the computed delay can be reused for isomorphic subcircuits.
摘要翻译：本发明的一个实施例提供了一种系统，其通过重新利用为同构子电路计算的延迟来加速时序分析。在操作期间，系统接收要分析的电路块，其中电路块是网表的形式。然后，系统将电路块细分成一组子电路。然后将子电路分成等价类，其中包含彼此拓扑上同构的子电路。接下来，系统通过用于电路块的时序图跟踪路径来执行定时分析。在此定时分析期间，每当子电路需要延迟时，系统确定是否已经为与子电路相关联的等效类计算了相应的延迟。如果是这样，系统重新使用延迟。如果不是，则系统计算子电路的延迟，然后将计算的延迟与等价类相关联，使得计算的延迟可以重用于同构子电路。

摘要： 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.

摘要： 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.

摘要： 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.
