Abstract

In advanced digital networks for providing selective point-to-point communications between subscribers terminals and broadband server equipment operated by a plurality of independent information service providers, routing through the network is controlled by functionality identified as a Level 1 Gateway. The Level 1 Gateway will perform a variety of functions including communications port management of transmissions of information between subscribers and servers, processing of billing information and session management. The Level 1 Gateway generates menus of providers, either as a function of providers available through a particular portion of the network or in a customized fashion specified by individual subscribes. The Level 1 Gateway may also provide a PIN number functionality, e.g. to permit parents to limit which providers their children can access. The Level 1 Gateway is itself an interactive device in that subscribers can input information and receive display information from the Gateway to define or modify their own video dial tone service through the network.

Claims

1. In a broadband communication network selectively providing broadband communication links between servers operated by a plurality of information service providers and a plurality of subscriber terminals, a communication method comprising:

receiving a selection of a service provider from a subscriber'"'"'s terminal at a gateway within the network;

controlling the broadband communication network to establish a broadband communication link through the network between a server operated by the selected service provider and the subscriber'"'"'s terminal;

accumulation data at said gateway, said data specifyng duration of connect time for the established broadband communication link; and

billing based on the connect time data, comprising;

(1) calculating a network service charge for the broadband communication link based on the connect time duration; and

(2) generatinz a bill to the selected service provider for the network service charge.

2. A method as in claim 1, wherein the step of billing comprises:

calculating a service charge for a service provided by the selected service provider through said broadband communication link; and

generating a bill to the subscriber for the service charge.

3. A method as in claim 1, further comprising:

monitoring status of the established broadband communication link; and

terminating the accumulation of data in response to occurrence of a fault or interruption in the established broadband communication link.

4. A method as in claim 3, further comprising:

after the occurrence of a fault or interruption in the established broadband communication link, transmitting a message indicating a fault or interruption to the subscriber'"'"'s terminal; and

displaying a notice of the fault or interruption to the subscriber.

5. A method as in claim 1, wherein the established broadband communication link provides downstream transport for digitized and compressed audio/video information from the broadband server to the subscriber'"'"'s terminal for presentation to the subscriber.

6. A system comprising:

a communication network selectively providing broadband communication links;

a plurality of information service provider systems connected to the network, each provider system being capable of transmitting broadband digital information via a communication link through the network;

a plurality of terminals for transmitting control signals upstream through the network in response to user inputs and for providing displays in response to broadband digital information received through the network from provider systems;

a gateway controlling the network to establish broadband communication links through the network between the information service provider systems and the terminals, and accumulating usage data regarding each established broadband communication link for billing for links established to the service provider systems; and

a billing system, receiving the usage data from the gateway system, for calculating a network service charge for at least one broadband communication link established between one terminal and a selected service provider'"'"'s system based on the usage data, and generating a bill to the selected service provider for the network service charge.

7. A system as in claim 6, wherein the billing system calculates a service charge for a service provided by the selected service provider through said at least one broadband communication link, and generates a bill to the one subscriber for the service charge.

8. A system as in claim 6, further comprising means for monitoring status of established broadband communication links and reporting to the gateway any faults or interruptions detected in established broadband communication links, wherein the gateway terminates accumulation of usage data with respect to any broadband communications for which a fault or interruption has been reported.

9. In a system comprising:

a communication network selectively providing broadband communication links;

a plurality of information service provider systems connected to the network, each provider system being capable of transmitting broadband digital information via a communication link through the network; and

a plurality of terminals for transmitting control signals upstream through the network in response to user inputs and for providing displays in response to broadband digital information received through the network from provider systems;

a gateway for;

(1) controlling the network to establish broadband communication links through the network between the information service provider systems and the terminals,

(2) accumulating usage data regarding each established broadband communication link for billing,

(3) calculating a network service charge for at least one of the established broadband communication links based on the corresponding usage data, and

(4) generating a bill to the corresponding information service provider system for the network service charge.

10. A gateway for use in a broadband communication network comprising:

a service data module maintaining service data files relating to information service providers offering services through the broadband communication network and information users subscribing to service through the broadband communication network;

a service control module for interacting with users through users terminals coupled to the broadband communication system, said service control module generating requests for broadband communication sessions between selected providers and selecting users terminals in response to selection information from the selecting users terminals and data files maintained by the service data module;

a session management module, responsive to the requests for broadband communication sessions, for identifying end to end communication connectivity needed for each requested broadband communication session, generating requests for the identified end to end communication connectivity and collecting usage information relating to established broadband communication sessions; and

a connection management module, responsive to the instructions from the session management module, for identifying entry and exit points through one or more subsections of the broadband communication network for the end to end communication connectivity needed for each requested broadband communication session, and interacting with a control element of each of the one or more subsections of the broadband communication network to obtain communications connectivity through each of the one or more subsections of the broadband communication network to establish the end to end communication connectivity needed for each requested broadband communication session, and for confirming establishment of each requested broadband communication session to the session management module.

11. A gateway as in claim 10, wherein the service control module comprises:

a directory submodule for maintaining listing information regarding information service providers offering services through the broadband communication network for presentation to users, and receiving selections from users terminals, and translating the selections into service requests; and

a session agent submodule for translating the service requests from the directory submodule into the requests for broadband communication sessions between selected providers and selecting users terminals.
