Abstract: A communication system providing telephony communication across combined circuit switched and packet switched networks, such as a telephone network and the Internet, which are connectable to terminals, such as telephones and computers, for selective communication therebetween. The communication system includes a directory object in the packet switched network, multiple gateways between the circuit switched and packet switched networks providing controlled connectivity between those networks, and an interface between the directory object and the gateways. The directory object is preferably provided in hierarchical architecture as a unitary logical object having distributed instances. In addition to the customary address translation capability the directory object polls or communicates with the gateways through the additional interface and provides an intelligent routing function. The directory object is of an enhanced type with access to a storage of customer routing and handling selections.

Abstract: An internetwork (such as the Internet) telephony system and method incorporating architecture and methodology which facilitates a high degree of scalability. The scalability provides improvement dealing with usage recording, usage pricing, billing account management, and fraud control. The scalability is achieved primarily by bundling of usage recording, pricing, authorization and billing practices in one logical database object which may be physically distributed. A predefined set of network elements are provided access to the database object to obtain authorization for a call along with limitations on the maximum cost or duration of the call for the particular account involved. The database object records usage statistics relating to the completed call, including pricing, and this data is available for virtually immediate billing. The database object provides to customers on a virtual real time basis the customer's usage statistics, including statistics for a call in progress.

Abstract: A system and method for providing telephone type services over the internetwork commonly known as the Internet. Public switched telephone networks utilizing program controlled switching systems are arranged in an architecture with the Internet to provide a methodology for facilitating telephone use of the Internet by customers on an impromptu basis. Provision is made to permit a caller to set-up and carry out a telephone call over the Internet from telephone station to telephone station without access to computer equipment, without the necessity of maintaining a subscription to any Internet service, and without the requiring Internet literacy or knowledge. Calls may be made on an inter or intra LATA, region or state, nationwide or worldwide basis. Billing may be implemented on a per call, timed, time and distance or other basis. Usage may be made of common channel interoffice signaling to set up the call and establish the necessary Internet connections and addressing.

Abstract: A telecommunications system wherein the dialing of a directory number which has been ported triggers an intelligent network signal which is directed to the Internet. The signal is transmitted through the Internet to a database in the Internet. The database returns call set up directions which are used by the originating switching system to establish a voice link from the calling station to the station having the ported number. The intelligent network signal may be transmitted from the originating switching system to a signal transfer point (STP) and to the Internet. Within the Internet the signal is directed to an Internet database where a real number for the ported number is obtained. This is transmitted back to the signal switching point, which then uses the real number to complete the connection. In another embodiment, where a number has been ported to a station that is connected only to the Internet, the Internet database may provide a domain name address.

Abstract: A telecommunications system wherein the dialing of a directory number which has been forwarded triggers an intelligent network signal which is directed to the Internet. The signal is transmitted through the Internet to a database in the Internet. The database returns call set up directions which are used by the originating switching system to establish a voice link from the calling station to the station having the forwarded number. The intelligent network signal may be transmitted from the terminating switching system to a signal transfer point (STP) and to the Internet. Within the Internet the signal is directed to an Internet database where a forwarding number for the forwarded number is obtained. This is transmitted back to the signal switching point, which then uses the forwarding number to complete the connection. In another embodiment, where a number has been forwarded to a station that is connected only to the Internet, the Internet database may provide a domain name address.

Abstract: Overload protection for dial-up access to the Internet uses a hybrid network including the Internet and an intelligent switched telephone network. A first Internet service provider (ISP) connects to the Internet through its server and router interface. This ISP also connects to a switching system in the telephone network; to provide dial-up service to user terminals connected to the telephone network. A service control point (SCP) in the intelligent telephone network monitors predetermined traffic criteria resulting from dial-up attempts to call the ISP. Threshold parameters are set in storage associated with the SCP, and at least certain of the measured criteria are substantially continually compared to one or more of these parameters. When one or more of the parameters is equaled or exceeded, the SCP causes redirection of calls for the first ISP to an Internet interface provided by an alternate access provider. The alternate Internet access provider may or may not provide independent ISP services.

Abstract: The routing of signals in a telecommunication network 100' comprising a plurality of interconnected nodes 102, 103, 104, 104', 105, 106, 106' and 107, such as a SONET ring network, is modified through use of a controller 160. The controller 160 maintains a mapping between the telephone numbers of subscriber locations 132, 138, and the network nodes 104', 106' to Which the subscriber locations are attached The ring controller 160 permits a subscriber location to change the node to which it is attached without changing its telephone number. Utilizing the ring controller, new services such as ISDN, can be offered to a large body of potential subscribers while only a limited number of central offices are actually upgraded.
