Abstract

A method for allowing multiple service providers (20,22,24) to provide services via a common access network (12). The access network (12) is arranged with multiple logical network layers, each .specific to a respective service provider. Upon successful authentication of a subscriber (14) by a given service provider, the access network 12) assigns that subscriber to the logical layer specific to the authenticating service provider. The access network then handles communication traffic in that logic layer in a manner specific to the service provider.

receiving a second indication that the second subscriber has been authenticated by a second service provider, and responsively assigning the second subscriber to operate in a second logical layer of the access network;
handling communications in the first logical layer according to a first logic set; and handling communications in the second logical layer according to a second logic set different than the first logic set.
2. The method of claim l, further comprising:
before receiving the first indication, assigning the first subscriber to operate in a default logical layer of the access network; and handling communications in the default logical layer according to a default logic set different than the first logic set.
3. The method of claim 2, wherein the access network is an IP network, and wherein:
the first logical layer comprises a first If subnet;
the second logical layer comprises a second IP subnet; and the default logical layer comprise a default IP subnet.
4. The method of claim 2, wherein handling communications according to the default logic set comprises disallowing a certain type of communication, and handling communications according to the first logic set comprises allowing the certain type of communication.
5. The method of claim 4, wherein the certain type of communication comprises a SIP communication.
6. The method of claim 1, wherein handling communications in the first logical layer according to the first logic set comprises:
disallowing communications from the first logical layer to outside of the access network.
7. The method of claim 1, wherein handling communications in the first logical layer according to the first logic set comprises:
disallowing a predetermined type of communication from passing from the first logical layer to outside of the access network.
8. The method of claim l, wherein handling communications in the first logical layer according to the first logic set comprises:
detecting a web page being sent to an address on the first logical layer; and injecting into the web page information specific to the first service provider.
9. The method of claim 8, wherein the information comprises an advertisement for the first service provider.
10. The method of claim 1, wherein the access network is an IP network, and wherein:
the first logical layer comprises a first IP subnet; and the second logical layer comprises a second IP subnet.
11. The method of claim 1, wherein the subscriber communicates via an air interface with the access network.
12. A method comprising:
allowing a first wireless subscriber to operate on an access network and assigning the first wireless subscriber to operate in a default IP subnet of the access network;

allowing a second wireless subscriber to operate on the access network and assigning the second wireless subscriber to operate in the default IP subnet of the access network;
receiving a first indication that the first wireless subscriber has been authenticated by a first service provider, and responsively assigning the first wireless subscriber to operate in a first IP subnet of the access network, the first IP subnet being different than the default IP
subnet;
receiving a second indication that the second wireless subscriber has been authenticated by a second service provider, and responsively assigning the second wireless subscriber to operate in a second IP subnet of the access network, the second IP subnet being different than the default IP subnet and being different than the first If subnet;
handling communications in the default IP subnet according to a default logic set;
handling communications in the first IP subnet according to a first logic set different than the default logic set; and handling communications in the second IP subnet according to a second logic set different than both the default logic set and the first logic set.
13. A method comprising:
receiving from a subscriber on an access network an authentication request, the authentication request identifying the subscriber and identifying a designated service provider from among a plurality of service providers;
sending the authentication request to the designated service provider;
receiving from the designated service provider an authentication response indicating successful authentication of the subscriber by the designated service provider;
responsive to the authentication response, assigning the subscriber to operate in a designated layer of the access network set aside for subscribers that have been authenticated by the designated service provider; and serving the subscriber in the designated layer of the access network.
14. The method of claim 13, wherein the access network is an 1P network and the designated layer is an IP subnet, and wherein assigning the subscriber to operate in the designated layer comprises assigning to the subscriber an IP address in the IP
subnet.
15. The method of claim 14, wherein serving the subscriber in the designated layer comprises handling communications with the subscriber according to a logic set established for the designated layer.
16. The method of claim 15, wherein handling communications with the subscriber according to the logic set established for the designated layer comprises:
detecting a packet bearing the IP address assigned to the subscriber; and responsively applying the logic set to restrict transmission of the packet.
17. The method of claim 13, wherein serving the subscriber in the designated layer of the access network comprises:
a gateway on the access network detecting a web page being sent to the subscriber;
the gateway modifying the web page to include an advertisement for the designated service provider.
18. The method of claim 13, further comprising prompting the subscriber to provide the authentication request.
19. The method of claim 18, wherein prompting the subscriber for the authentication request comprises:
presenting to the subscriber a set of the plurality of service providers; and prompting the subscriber to select a service provider from among the plurality presented, wherein the subscriber selects the designated service provider from among the plurality.
20. The method of claim 13, wherein the access network comprises a wireless access network.
21. A method carried out by an access network, the method comprising:
prompting a first client station to select a service provider from among a plurality of service providers, and receiving a signal from the first client station, indicating a first selected service provider;

sending a first authentication request message for the first client station to the first selected service provider, the first authentication request message indicating authentication information for the first client station;
receiving a first authentication response message from the first selected service provider, the first authentication response message indicating that first client station is authenticated by the first selected service provider; and in response to the first authentication response message, restricting the client station to communications in a first logical layer of the access network associated with the first selected service provider.
22. The method of claim 20, further comprising:
prompting a second client station to select a service provider from among a plurality of service providers, and receiving a signal from the second client station, indicating a second selected service provider;
sending a second authentication request message for the second client station to the first selected service provider, the second authentication request message indicating authentication information for the first client station;
