摘要： Computer program products, related methods, and a protocol for interworking services between a public telephone network, including an Intelligent Network, and an internet protocol network are provided. A public telephone network transports a TCAP message in an SS7 protocol format, and an internet protocol network, or IP network, transports an encapsulated TCAP message in an IP protocol format. A STIPP (Simple TCAP-IP Interworking Protocol) protocol, represented as a computer data signal including a plurality of bits, is used for exchanging TCAP messages between IP network entities. The computer data signal comprises an internet protocol portion, a transport portion, and a STIP (Simple TCAP Interworking Part) portion. The STIP portion includes a STIP header for encapsulating the TCAP message therein for transmission between IP network entities. Various computer data signal embodiments are provided. A computer program product for an interworking gateway exchanging TCAP messages with a public telephone network and encapsulated TCAP messages with an internet protocol network is provided. Further, a computer program product for an IP network entity exchanging encapsulated TCAP messages with an internet protocol network is provided. Message encapsulation, extraction, and decapsulation are provided. Various embodiments and functions are included for each computer program product. A method for exchanging TCAP messages between a public telephone network and an internet protocol network for services interworking is included. Further, a method for exchanging encapsulated TCAP messages with an internet protocol network, such that TCAP messages can ultimately be exchanged with a public telephone network through an internet protocol network is provided.

摘要： An apparatus, system, and method are provided for interworking the public telephone network and the IP network. The public telephone network transports a TCAP message in a first format, and the IP network transports an encapsulated TCAP message in a second format. A first interface communicates with the public telephone network, and exchanges TCAP messages therewith. A second interface communicates with the IP network, and exchanges encapsulated TCAP messages therewith. A processor operably connected to at least one of said first interface and said second interface translates TCAP messages in the first format to/from the encapsulated TCAP message in the second format. The processor is further adapted for forwarding TCAP messages in both formats to the respective network. The first format can be an SS7 protocol format, while the second format can be an IP protocol format as used in the IP network. Various message structures and encapsulation techniques are provided. Network addressing and routing functions are included. An apparatus for exchanging encapsulated TCAP messages with the IP network is provided. A system for interworking a public telephone network and an IP network is provided. The system comprises a first network node, a second network node, and at least one interworking apparatus having a processor adapted for exchanging TCAP messages with the public telephone network and the IP network, as described. Related methods for interworking between the IP network and the public telephone network are provided.

摘要： A method and system for Transmission Control Protocol (TCP) packet loss recovery over a wireless link where the packet loss is due to a high Bit Error Rate (BER). Such a method and system allows the exponential growth of a TCP congestion window for every acknowledgement packet that is received after a retransmission timers expires and/or three duplicate acknowledgement packets are received. In such a scenario, a maximum amount of data is transmitted via the exponentially growing TCP congestion window thereby optimizing and increasing packet throughput. A method and system for setting the congestion window to a greater amount than originally set of the maximum allowed window size is also presented. Further, a method and system for, as the BER changes between low and high, automatically adjusting the congestion window size to be a variable of the maximum allowed window size and dynamically adjusting the packet size is presented.

摘要： A computer protocol that manages and provides efficient communications and utilization of resources between a mobile computer system or device and other systems and devices. Each home agent maintains a home agent list containing information about each of the home agents coupled to the home link. A designated home agent on behalf of the home agents for a virtual home agent is used to send and broadcast home agent advertisement, to receive and process a request from a mobile node, to process and send a reply to the mobile node. Synchronization mechanisms or tools, such as home agent priority or floating token method, are provided for proper operation of a Virtual Distribution Home Agent Protocol (VDHAP). These mechanisms or tools are used to fairly distribute loads from the mobile node among the home agents within the virtual home agent.

摘要： An efficient and improved dynamic home agent discovery algorithm and system to be used in a protocol for network communications. The present invention encapsulates and integrates communications of the home agents into a single home agent communication. Communication between a mobile node and the home agents is simplified to a single home agent communication. Dynamic home agent discovery processes are performed, based on the single home agent communication. Encapsulation is achieved by having each of the home agents maintain a home agent list that contains information about each of the home agents coupled to the home link. A designated home agent receives and processes home agent discovery requests from the mobile node on behalf of home agents coupled to the home link, and a designated home agent sends home agent advertisements to and communicates with the mobile node.
