Abstract

A method connects one of several customer premises equipment (CPE) via an ATM network to one of several service providers (SP). Each CPE is connected to the ATM network via a corresponding network termination point (NT). There is an access server function (ASF), having a permanent virtual connection (PVC) to each NT and a connection to each SP. A tunneling protocol is established on the permanent virtual connection between each NT and the ASF. The tunneling protocol is able to support an integrated signaling protocol. The CPE or its user select selects an appropriate SP by using the integrated signaling protocol. Routing from the CPE to the selected SP is performed by the ASF. The ASF connects the CPE to the selected SP using the integrated signaling protocol.

Claims18

Dependent claims

A method for creating, maintaining, and releasing sessions between a plurality of customer premises equipment (CPE) and service providers via an Asynchronous Transfer Mode (ATM) access node, the method comprising:

connecting one or more CPEs to the ATM access node via a network termination (NT) point;
establishing a permanent virtual connection between the ATM access node and the NT point;
establishing a tunneling protocol integrated with a signaling protocol over the permanent virtual connection between the ATM access node and the NT point;
forming a virtual connection between the ATM access node and a service provider of choice on receipt of a request for a new session from the customer premise equipment indicating the service provider of choice, wherein only one virtual connection is formed between the ATM access node and each service provider;
and
at the ATM access node, performing routing between the customer premises equipment and the service provider using routing information provided by the signaling protocol.
