Mobility protocol selection by an authorization system
View Patent ↗A wireless network authorization system receives an authorization request for a wireless communication device transmitted from a visited wireless network. A processing system selects one of a simple internet connection and an encrypted internet connection for the wireless communication device in response to the authorization request. The communication interface transfers an authorization response for delivery to the visited wireless network indicating the selected one of the simple internet connection and the encrypted internet connection.
1. A method of operating a wireless network authorization system, the method comprising:
receiving an authorization request comprising a Diameter request message for internet access by a wireless communication device transmitted from a visited wireless network, the wireless network authorization system associated with a home wireless network of the wireless communication device;
in response to the authorization request, selecting one of a simple internet connection and an encrypted internet connection for the wireless communication device; and
transferring an authorization response comprising a Diameter response message for delivery to the visited wireless network indicating to the visited wireless network that the wireless communication device is to receive the selected one of the simple internet connection and the encrypted internet connection.
2. The method of claim 1 wherein:
receiving the authorization request comprises receiving the authorization request indicating an application being executed on the wireless communication device; and
selecting the one of the simple internet connection and the encrypted internet connection comprises selecting the one of the simple internet connection and the encrypted internet connection based on the indicated application.
3. The method of claim 1 wherein the encrypted internet connection comprises a secure tunnel to a home agent of the wireless communication device.
4. The method of claim 1 wherein selecting the one of the simple internet connection and the encrypted internet connection comprises selecting the encrypted internet connection based on a user profile for the wireless communication device that indicates an enterprise access user.
5. The method of claim 1 wherein selecting the one of the simple internet connection and the encrypted internet connection comprises selecting one of an IPv4 protocol and an IPv6 protocol.
6. The method of claim 5 wherein transferring the authorization response for delivery to the visited wireless network comprises transferring the authorization response indicating the selected one of the IPv4 protocol and the IPv6 protocol.
7. The method of claim 1 wherein the encrypted internet connection links the wireless communication device to the internet through a home wireless network.
8. The method of claim 1 wherein the simple internet connection links the wireless communication device to the internet without connecting through a home wireless network.
9. The method of claim 1 wherein the encrypted internet connection utilizes a mobile internet protocol.
10. A wireless network authorization system comprising:
a communication interface configured to receive an authorization request comprising a Diameter request message for internet access by a wireless communication device transmitted from a visited wireless network, the wireless network authorization system associated with a home wireless network of the wireless communication device;
a processing system configured, in response to the authorization request, to select one of a simple internet connection and an encrypted internet connection for the wireless communication device; and
the communication interface configured to transfer an authorization response comprising a Diameter response message for delivery to the visited wireless network indicating to the visited wireless network that the wireless communication device is to receive the selected one of the simple internet connection and the encrypted internet connection.
11. The wireless network authorization system of claim 10 wherein:
the communication interface is configured to receive the authorization request indicating an application being executed on the wireless communication device; and
the processing system is configured to select the one of the simple internet connection and the encrypted internet connection based on the indicated application.
12. The wireless network authorization system of claim 10 wherein the encrypted internet connection comprises a secure tunnel to a home agent of the wireless communication device.
13. The wireless network authorization system of claim 10 wherein the processing system is configured to select the one of the simple internet connection and the encrypted internet connection based on a user profile for the wireless communication device that indicates an enterprise access user.
14. The wireless network authorization system of claim 10 wherein the processing system is configured, in response to the authorization request, to select one of an IPv4 protocol and an IPv6 protocol.
15. The wireless network authorization system of claim 14 wherein the communication interface is configured to transfer the authorization response for delivery to the visited wireless network indicating the selected one of the IPv4 protocol and the IPv6 protocol.
16. The wireless network authorization system of claim 10 wherein the encrypted internet connection links the wireless communication device to the internet through a home wireless network.
17. The wireless network authorization system of claim 10 wherein the simple internet connection links the wireless communication device to the internet without connecting through a home wireless network.
18. The wireless network authorization system of claim 10 wherein the encrypted internet connection utilizes a mobile internet protocol.
