Level 1 Gateway for video dial tone networks
First Claim
1. In a communication network selectively providing broadband communication links between servers operated by a plurality of service providers and a plurality of subscriber terminals, a method comprising:
- receiving a selection of one of the service providers at a gateway control element of the network from one of the subscriber terminals;
controlling the broadband communication network to attempt to establish a broadband communication link through the network between a server operated by the selected service provider and the subscriber'"'"'s terminal;
determining that the broadband communication link can not be established through the network;
transmitting a message indicating inability to establish the broadband communication link to the subscriber'"'"'s terminal; and
in response to the transmitted message, providing a notice to the subscriber.

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.

9. A system comprising:
-
a communication network selectively providing broadband communications 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 information received through the network; controller means for controlling establishment of broadband communication links through the broadband communication network between the information service provider systems and the terminals; and a gateway instructing said controller means to establish links in response to requests from subscriber terminals and responsive to notification from the controller means that a link to a specific terminal can not be established or is subject to a fault or interruption for providing notice to said specific terminal.

11. A communication method comprising:
-
receiving a request for service from a subscriber'"'"'s terminal at a level 1 gateway control element of a broadband communication network; in response to the request for service, generating menu information listing a plurality of broadband information service providers available through the broadband digital communication network; transmitting said menu information from the level 1 gateway to the terminal; visually displaying the menu to the subscriber; receiving a selection of a service provider listed on the menu from the subscriber'"'"'s terminal at the level 1 gateway; transmitting a query message from the level 1 gateway for a level 2 gateway operated by the selected service provider identifying the subscriber'"'"'s terminal; if the level 2 gateway is ready to accept communications from the subscriber'"'"'s terminal; (1) establishing a narrowband signaling communication between the level 2 gateway and the subscriber'"'"'s terminal, (2) establishing a broadband digital communication though the network between a broadband server associated with the level 2 gateway and the subscriber'"'"'s terminal, (3) transmitting digitized, compressed audio/video information through the established broadband communication from the broadband server to the subscriber'"'"'s terminal; and if the level 2 gateway is not ready to accept communications from the subscriber'"'"'s terminal; (a) transmitting a notification message to the subscriber'"'"'s terminal, and (b) displaying the notification message to the subscriber.
