Residential gateway based policy
View Patent ↗Various exemplary embodiments relate to a method performed by a policy server in a communication network. The method includes receiving an access request message including a residential gateway identifier and a subscriber identifier; evaluating a policy rule based on the residential gateway identifier, the policy rule including a condition referencing the residential gateway identifier; and responding to the access request message based on evaluation of the policy rule and the subscriber identifier. The method may further include: receiving an IP address of the residential gateway; storing the IP address in association with the residential gateway identifier; receiving, from a service portal, a request for identification of a residential gateway associated with an IP address; sending the stored residential gateway identifier to the portal; receiving new subscriber information; and changing the authorization of the residential gateway based on the new subscriber information.
1. A method performed by a policy server in a communication network comprising:
receiving an access request message including a residential gateway identifier and a subscriber identifier;
evaluating a policy rule based on the residential gateway identifier, the policy rule including a condition referencing the residential gateway identifier;
responding to the access request message based on evaluation of the policy rule and the subscriber identifier;
receiving an IP address of the residential gateway; storing the IP address in association with the residential gateway identifier;
receiving, from a service portal, a request for identification of a residential gateway associated with an IP address;
sending the stored residential gateway identifier to the service portal;
receiving new subscriber information; and
changing an authorization of the residential gateway based on the new subscriber information.
2. The method of claim 1 , wherein the residential gateway identifier is a dynamic host configuration protocol (DHCP) option 60 vendor class identifier.
3. The method of claim 2 , further comprising comparing the vendor class identifier to predefined identifiers and determining a type of the residential gateway.
4. The method of claim 1 , wherein the residential gateway identifier is a Media Access Control (MAC) address.
5. The method of claim 4 , further comprising comparing the MAC address to an address prefix.
6. The method of claim 1 , wherein the step of responding to the access request message based on evaluation of the policy rule and the subscriber identifier comprises:
determining that the subscriber identifier is not associated with a valid service plan;
authorizing a default session allowing the residential gateway to communicate with a service portal; and storing the residential gateway identifier and the subscriber identifier in association with the default session.
7. The method of claim 1 , further comprising: determining residential gateway capabilities based on the residential gateway identifier; and sending the residential gateway capabilities to the service portal.
8. The method of claim 1 , wherein the condition references a plurality of network gateway identifiers.
9. A policy server comprising:
a memory and a hardware processor;
a network interface configured to receive an access request message initiated by a residential gateway attaching to a network, the access request message including a residential gateway identifier and a subscriber identifier; and
a rules engine processor configured to evaluate conditions of policy rules, execute actions corresponding to true conditions, at least one policy rule including a condition based on the residential gateway identifier;
receive an IP address of the residential gateway;
store, in the memory, the IP address in association with the residential gateway identifier;
receive, from a service portal, a request for identification of a residential gateway associated with an IP address;
send the stored residential gateway identifier to the service portal;
receive new subscriber information; and
change an authorization of the residential gateway based on the new subscriber information.
10. The policy server of claim 9 , wherein the condition of the at least one policy rule includes a certified residential gateway identifier and the action of the at least one policy rule instructs the rules engine to allow a session providing service to the residential gateway.
11. The policy server of claim 10 , further comprising: a session information storage configured to store information regarding the session including the residential gateway identifier; and an application programming interface configured to provide an external service portal access to the session information and configured to receive subscriber information from the external service portal.
12. The policy server of claim 9 , further comprising:
a device mapper configured to determine residential gateway characteristics based on the residential gateway identifier.
13. The policy server of claim 12 , further comprising: a session information storage configured to store the residential gateway characteristics determined by the device mapper; and an application programming interface configured to provide an external service portal access to the residential gateway characteristics and configured to receive the subscriber information from the service portal.
14. A non-transitory computer-readable storage medium encoded with instructions executable by a processor of a policy server, the non-transitory computer-readable medium comprising instructions for:
receiving an access request message including an residential gateway identifier and a subscriber identifier;
evaluating a policy rule based on the residential gateway identifier, the policy rule including a condition referencing the residential gateway identifier;
responding to the access request message based on evaluation of the policy rule and the subscriber identifier; receiving an IP address of the residential gateway;
storing the IP address in association with the residential gateway identifier;
receiving, from a service portal, a request for identification of a residential gateway associated with an IP address;
sending the stored residential gateway identifier to the service portal; receiving new subscriber information: and
changing an authorization of the residential gateway based on the new subscriber information.
15. The non-transitory machine-readable storage medium of claim 14 , wherein the residential gateway identifier is a dynamic host configuration protocol (DHCP) option 60 vendor class identifier, the non-transitory machine-readable storage medium, further comprising instructions for comparing the vendor class identifier to predefined identifiers and determining a type of the residential gateway.
16. The non-transitory machine-readable storage medium of claim 14 , wherein the residential gateway identifier is a Media Access Control (MAC) address, the non-transitory machine-readable storage medium
further comprising instructions for comparing the MAC address to an address prefix.
17. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions for responding to the access request message based on evaluation of the policy rule and the subscriber identifier comprise instructions for: determining that the subscriber identifier is not associated with a valid service plan; authorizing a default session allowing the residential gateway to communicate with a service portal; and storing the residential gateway identifier and the subscriber identifier in association with the default session.
18. The non-transitory machine-readable storage medium of claim 14 , further comprising instructions for: determining residential gateway capabilities based on the residential gateway identifier; and sending the residential gateway capabilities to the service portal.
