Abstract
A method of allowing interworking authorization of dual stack operation is provided. The method allows for simultaneous operation in both IPv4 and IPv6 if a terminal is authorized and authenticated to use both versions. The method utilizes the following steps: requesting authentication from an authorization entity in a wireless communication system; and receiving an authentication message from the authorization entity if the authentication is successful wherein the authentication message contains an authorization to use at least one internet protocol version to establish at least one secure tunnel for communication.

Claim
1. A method comprising:
requesting, at a mobile station, authentication from a home authorization device in a wireless communication system; and
receiving an authentication message from the home authorization device if the authentication is successful, wherein the authentication message contains an authorization to use 1) a first internet protocol version only and not a second internet protocol version, 2) the second internet protocol version only and not the first internet protocol version, or 3) both the first and second internet protocol versions to establish at least one wireless secure tunnel with the mobile station for communication.
2. The method of claim 1, wherein the authorization to use the two internet protocol versions is a IP-Version-Authorized VSA sent in a RADIUS Access-Accept message.
3. The method of claim 2, wherein if the IP-Version-Authorized VSA is not present in the RADIUS Access-Accept message, a packet data interworking function in the wireless communication network shall apply local policy for authorizing dual stack operation.
4. The method of claim 1, wherein the first internet protocol versions is internet protocol version 4 (IPv4) and the second internet protocol version is internet protocol version 6 (IPv6), and wherein, in response to an authorization to use both IPv4 and IPv6, both IPv4 and IPv6 access a same packet data interworking function (PDIF) of the home authorization device.
5. The method of claim 4, wherein both IPv4 and IPv6 simultaneously access separate wireless secure tunnels, and wherein the authorization is a dual-stack authorization for IPv4 and IPv6.
6. A mobile station comprising:
a transmitter for requesting authentication from a home authorization device in a wireless communication system; and
a receiver for receiving an authentication message from the home authorization device if the authentication is successful, wherein the authentication message contains an authorization to use 1) a first internet protocol version only and not a second internet protocol version, 2) the second internet protocol version only and not the first internet protocol version, or 3) both the first and second internet protocol versions to establish at least one wireless secure tunnel with the mobile station for communication.
7. The mobile station of claim 6, wherein the authorization to use the two internet protocol versions is a IP-Version-Authorized VSA sent in a RADIUS Access-Accept message.
8. The mobile station of claim 7, further comprising:
a processor for storing local policy for authorizing dual stack operation, wherein if the IPVersion-Authorized VSA is not present in the RADIUS Access-Accept message, a packet data interworking function in the wireless communication network shall apply local policy for authorizing dual stack operation.
9. The mobile station of claim 6, wherein the first internet protocol versions is internet protocol version 4 (IPv4) and the second internet protocol version is internet protocol version 6 (IPv6), and wherein, in response to an authorization to use both IPv4 and IPv6, both IPv4 and IPv6 access a same packet data interworking function (PDIF) of the home authorization device.
10. The mobile station of claim 9, wherein both IPv4 and IPv6 simultaneously access separate wireless secure tunnels, and wherein the authorization is a dual-stack authorization for IPv4 and IPv6.
11. A mobile station comprising:
means for requesting, at the mobile station, authentication from a home authorization device in a wireless communication system; and
means for receiving an authentication message from the home authorization device if the authentication is successful, wherein the authentication message contains an authorization to use 1) a first internet protocol version only and not a second internet protocol version, 2) the second internet protocol version only and not the first internet protocol version, or 3) both the first and second internet protocol versions to establish at least one wireless secure tunnel with the mobile station for communication.
12. The mobile station of claim 11, wherein the authorization to use the two internet protocol versions is a IP-Version-Authorized VSA sent in a RADIUS Access-Accept message.
13. The mobile station of claim 12, wherein if the IP-Version-Authorized VSA is not present in the RADIUS Access-Accept message, a packet data interworking function in the wireless communication network shall apply local policy for authorizing dual stack operation.
14. The mobile station of claim 11, wherein the first internet protocol versions is internet protocol version 4 (IPv4) and the second internet protocol version is internet protocol version 6 (IPv6), and wherein, in response to an authorization to use both IPv4 and IPv6, both IPv4 and IPv6 access a same packet data interworking function (PDIF) of the home authorization device.
15. The mobile station of claim 14, wherein both IPv4 and IPv6 simultaneously access separate wireless secure tunnels, and wherein the authorization is a dual-stack authorization for IPv4 and IPv6.
16. A non-transitory computer program product comprising:
a non-transitory computer-readable medium comprising:
instructions for causing a computer to request, at a mobile station, authentication from a home authorization device in a wireless communication system; and
instructions for causing the computer to receive an authentication message from the home authorization device if the authentication is successful, wherein the authentication message contains an authorization to use 1) a first internet protocol version only and not a second internet protocol version, 2) the second internet protocol version only and not the first internet protocol version, or 3) both the first and second internet protocol versions to establish at least one wireless secure tunnel with the mobile station for communication.
17. The computer program product of claim 16, wherein the first internet protocol versions is internet protocol version 4 (IPv4) and the second internet protocol version is internet protocol version 6 (IPv6), and wherein, in response to an authorization to use both IPv4 and IPv6, both IPv4 and IPv6 access a same packet data interworking function (PDIF) of the home authorization device.
18. The computer program product of claim 17, wherein both IPv4 and IPv6 simultaneously access separate wireless secure tunnels, and wherein the authorization is a dual-stack authorization for IPv4 and IPv6.
