Abstract

A network system that identifies a home network of a user by a network identification in an access request. When the access request is received in a network, the accessed network extracts a network identification from the access request and determines whether the access request is received from a subscriber or non-subscriber. If a non-subscriber, then a foreign network is identified and a network identification database is consulted to retrieve contact information for the foreign network. If the contact information is successfully retrieved, then the user may be routed to the foreign network (home network of the user). Otherwise (if the contact information is not in the network identification database), the user may be denied any access, and a purchase agreement for connect services may be offered.

Claims

1. A method for responding to an access request from a device, comprising:

receiving the access request from the device;

extracting a network identification from the access request;

identifying a foreign network based on the network identification;

obtaining foreign network information relating to the foreign network;

obtaining a profile from the foreign network information if the foreign network information indicates that an agreement is not established with the foreign network;

obtaining from the profile whether to negotiate with the foreign network for connecting the device to the foreign network; and

connecting the device to the foreign network if a successful negotiation is achieved.

2. The method of claim 1, wherein the foreign network information is obtained by retrieving the foreign network information from a network identification resolution database.

3. The method of claim 1, wherein the network identification includes a domain name of the foreign network.

4. A method for responding to an access request from a device, comprising:

receiving the access request from the device;

extracting a network identification from the access request;

identifying a foreign network based on the network identification;

obtaining foreign network information relating to the foreign network;

obtaining a profile from the foreign network information if the foreign network information indicates that an agreement is not established with the foreign network;

obtaining from the profile whether to offer connecting the device to the foreign network for a fee; and

connecting the device to the foreign network if the device accepts the offer.

5. The method of claim 4, wherein the foreign network information is obtained by retrieving the foreign network information from a network identification resolution database.

6. The method of claim 4, wherein the network identification includes a domain name of the foreign network.

7. A method for responding to an access request from a device, comprising:

receiving the access request from the device;

extracting a network identification from the access request;

identifying a foreign network based on the network identification;

obtaining foreign network information relating to the foreign network;

offering a network access service if a foreign network cannot be identified based on the network identification; and

providing the network access service if the offering is accepted.

8. The method of claim 7, wherein the foreign network information is obtained by retrieving the foreign network information from a network identification resolution database.

9. The method of claim 7, wherein the network identification includes a domain name of the foreign network.
