Connections on demand between subscribers and service providers
First Claim
1. A method for establishing a data communication path between a service terminal (ST) and a service provider (SP) across a telecommunication network (net), said method comprising the steps of:
- establishing a connection (C) across said telecommunication network between a network termination (NT), to which said service terminal is coupled, and an access server (AS), to which said service provider is coupled, forwarding in said access server traffic related to said service terminal to said connection, forwarding in said network termination traffic related to said service provider to said connection, characterized in that said connection is established after said service terminal has requested a service (S) from said service provider, and on condition that an authentication server (AUTH) has granted said service terminal the access to said service, in that said connection is established according to transport requirements (TR) of said service, and in that said transport requirements are supplied by said authentication server.

Abstract
The present invention relates to the ability to set up connections on demand between subscribers and service providers and allows network capacity to be best shared among users. Whenever a service terminal (ST) requests a service (S) from a service provider (SP), an authentication server (AUTH) checks whether the service terminal can access the requested service. If so, a network controller (CTRL) set up a connection (C) to deliver the requested service with the required quality of service, said connection being established between the network termination (NT), to which the service terminal is coupled, and the access server (AS), to which the service provider is coupled. The authentication server supplies transport requirements of the requested service for establishing the connection.
The access server and the network termination comprise forwarding means (FW1, FW2) adapted to discriminate the traffic related to said service and to forward it to the appropriate connection, thereby establishing the end to end data communication path between the service terminal and the service provider. The authentication server supplies forwarding criteria for establishing the end to end data communication path.

1. A method for establishing a data communication path between a service terminal (ST) and a service provider (SP) across a telecommunication network (net),
said method comprising the steps of: -
establishing a connection (C) across said telecommunication network between a network termination (NT), to which said service terminal is coupled, and an access server (AS), to which said service provider is coupled, forwarding in said access server traffic related to said service terminal to said connection, forwarding in said network termination traffic related to said service provider to said connection, characterized in that said connection is established after said service terminal has requested a service (S) from said service provider, and on condition that an authentication server (AUTH) has granted said service terminal the access to said service, in that said connection is established according to transport requirements (TR) of said service, and in that said transport requirements are supplied by said authentication server. - View Dependent Claims (2, 3, 4)

5. A telecommunication network (NET) comprising:
-
a root node (N1), to which an access server (AS) is coupled, a leaf node (N2), to which a network termination (NT) is coupled, a network controller (CTRL) adapted to establish a connection (C) across said telecommunication network between said network termination and said access server, characterized in that said network controller is further adapted to establish said connection after a service terminal (ST), coupled to said network termination, has requested a service (S) from a service provider (SP), coupled to said access server, and on condition that an authentication server (AUTH) has granted said service terminal the access to said service, in that said network controller is further adapted to establish said connection according to transport requirements (TR) of said service, and in that said transport requirements are supplied by said authentication server. - View Dependent Claims (6, 7, 8, 9, 10)

11. A network controller (CTRL) adapted to establish a connection across a telecommunication network (NET) between a network termination (NT) and an access server (AS),
characterized in that said network controller is further adapted to establish said connection after a service terminal (ST), coupled to said network termination, has requested a service (S) from a service provider (SP), coupled to said access server, and on condition that an authentication server (AUTH) has granted said service terminal the access to said service, in that said network controller is further adapted to establish said connection according to transport requirements (TR) of said service, and in that said transport requirements are supplied by said authentication server.
-
13. An authentication server (AUTH) adapted to grant or deny a service terminal (ST) the access to a service (S) of a service provider (SP),
characterized in that said authentication server is further adapted, after said service terminal has been granted said service, to supply transport requirements (TR) of said service for a network controller (CTRL) to establish a connection (C) across a telecommunication network (NT) between a network termination (NT), to which said service terminal is coupled, and an access server (AS), to which said service provider is coupled.
-
17. A network termination (NT) adapted to couple a service terminal (ST) to a telecommunication network (NET), and comprising:
-
local management means (MGT2) adapted to get via a control channel (CC1) characteristics of a connection (C) established between said network termination and an access server (AS), to which a service provider (SP) is coupled, forwarding means (FW2) adapted to forward traffic related to said service provider to said connection, characterized in that said local management means are further adapted, after said service terminal has requested a service (S) from said service provider, to get via said control channel forwarding criteria (CR2) for forwarding traffic related to said service to said connection, and in that said forwarding means are further adapted to forward traffic conforming with said forwarding criteria to said connection. - View Dependent Claims (18)
