Abstract

Network services provided by network access points to a plurality of communication terminals are regulated. Subscriber information that defines which of a plurality of network service levels is allocated to the communication terminals is maintained by at least one network service provider system. Network service levels that are provided by the network access points to the communication terminals are regulated in response to the subscriber information. A network access point may thereby be regulated to provide different levels of network service to different communication terminals. Moreover, a communication terminal may obtain a level of network service that may be based upon that provided by a home network service provider with which it is registered while the communication terminal is roaming through a different network service provider.

2. The method of claim 1, wherein:

the at least one network service provider system comprises an Internet service provider system;

the network access point comprises a wireless local area network access point; and

the wireless local area network access point is regulated to provide Internet communications to the communication terminal according to the second network service level.

3. The method of claim 1, wherein regulating network service levels provided by the network access points comprises:

regulating communication bandwidth levels provided by each of the network access points to each of the communication terminals in response to the subscriber information.

4. The method of claim 3, wherein:

the subscriber information allocates a first level of maximum communication bandwidth to a first communication terminal of a first subscriber and a second level of maximum communication bandwidth, which is different from the first level, to a second communication terminal of a second subscriber; and

the network access point is regulated in response to the subscriber information to provide the second level of maximum communication bandwidth to the second communication terminal of the second subscriber and to provide the first level of maximum communication bandwidth to first communication terminal of the first subscriber.

5. The method of claim 4, further comprising:

regulating the network access point to prioritize providing the first level of maximum communication bandwidth to the first communication terminal at a higher priority than providing the second level of maximum communication bandwidth to the second communication terminal in response to the subscriber information indicating that the first communication terminal and a subscriber network access line, which connects the network access point to the at least one network service provider, are both registered to the first subscriber.

6. The method of claim 4, further comprising:

regulating the network access point to provide the first level of maximum communication bandwidth to the second communication terminal while receiving the access request therefrom; and

after granting access to the second communication terminal to communicate through the network access point to a wide area network, regulating the network access point to provide the second level of maximum communication bandwidth to the second communication terminal in response to the subscriber information.

7. The method of claim 1, wherein:

the subscriber information does not authorize voice over internet protocol service for a first communication terminal of a first subscriber and authorizes voice over internet protocol service for a second communication terminal of a second subscriber; and

the network access point is regulated in response to the subscriber information to allow voice over internet protocol service to the second communication terminal and to deny voice over internet protocol service to the first communication terminal.

8. The method of claim 1, wherein:

the subscriber information does not authorize internet protocol game service for a first communication terminal of a first subscriber and authorizes internet protocol game service for a second communication terminal of a second subscriber; and

the network access point is regulated in response to the subscriber information to allow internet protocol game service to the second communication terminal and to deny internet protocol game service to the first communication terminal.

9. The method of claim 1, further comprising:

receiving from a communication terminal an access request at a network access point of a first network subscriber who has registered with the at least one network service provider system to receive a first network service level; and

determining that the communication terminal is not listed among subscriber information maintained by a first network service provider system that provides wide area network access to the network access point.

10. The method of claim 9, further comprising:

prompting a user of the communication terminal to confirm that the user accepts roaming charges for obtaining the second network service level at the network access point; and

selectively providing the second network service level through the network access point to the communication terminal based on the user'"'"'s response, via the communication terminal, to the prompt.

11. The method of claim 10, further comprising charging the user through the second network service provider system based on the user'"'"'s confirmation response, via the communication terminal, to the prompt.

12. The method of claim 1, wherein:

the network service provider systems comprise Internet service provider systems;

the network access point comprises a wireless local area network access point; and

determining that the communication terminal is not listed among subscriber information maintained by a first network service provider system that provides wide area network access to the local area network access point comprises;

identifying a MAC address associated with a wireless local area network transceiver of the communication terminal; and

using the identified MAC address to determine that the communication terminal is not listed among subscriber information maintained by the first network service provider system that provides wide area network access to the wireless local area network access point and to determine that the communication terminal is listed among subscriber information maintained by the second network service provider system.

13. The method of claim 12, further comprising:

maintaining a subscriber account database in the first network service provider system that identifies at least one media access control address of at least one communication terminals registered to a first subscriber and identifies which of the plurality of network service levels are allocated to the media access control address; and

maintaining a subscriber account database in the second network service provider system that identifies at least one media access control address of at least one communication terminals registered to a second subscriber and identifies which of the plurality of network service levels are allocated to the media access control address.

14. A local area network access point comprising:

a registration controller that is configured to receive access requests from communication terminals, to communicate the access requests to a first network service provider system, and to receive network service level information from the first network service provider system in response to the access requests, wherein the registration controller is further configured to determine that a communication terminal, which is requesting access to the local area network access point is not registered with the first network service provider system, and, in response to the determination, to request network service level information from a second network service provider system via the first network service provider system;
