  • Patent number: 7773513
    Abstract: A heterogeneous communication system comprises a plurality of heterogeneous access networks and a core network connecting the heterogeneous access networks. An admission server of the core network receives resource indications indicative of an estimated resource usage for a given communication service and a given access point of an access network. The admission server furthermore determines and stores current resource availability indications for access points. When a communication session request comprising a communication service indication and an access point identification is received, the admission server determines an estimated resource requirement for the communication sessions based on the resource indications. The admission server then determines whether to allow the communication session dependent on the resource availability for the access point and the estimated resource requirement for the communication service.

  • Publication number: 20090059788
    Abstract: An intermediate device of a network includes network and transport layers, a dispatcher, a splitter and a connections database. The splitter intercepts a message packet in the network layer and modifies the network routing header and transport header of the message packet to form a modified message packet. The dispatcher receives modified message packets from the transport layer, recovers information from the message packets, passes the modified message packets back to the transport layer and adapts the transport layer to adapt communication dependent upon the information recovered from the message packets. The connections database stores the original source address, the original destination address, the original source port identifier and the original destination port identifier of an incoming message packet. A message packet is modified, with reference to the connections database, so that message packets from the first and second nodes are routed through the dispatcher.

  • Publication number: 20070240209
    Abstract: The present disclosure provides methods and systems for preventing the termination of a communication session between two devices, where the communication session is being conducted over a wireless network, at least in part. More specifically, the present disclosure provides methods and systems for the prevention of a TCP session's premature termination, or TCP session persistence, in such a network by simulating signals of normal communication so that the receiving device “believes” that the simulated signals have been transmitted from the other device. Simulated signals, sent from a session persistence driver, are only sent to a device when expected signals which are expected to be received by that device are not detected.
