Abstract

The present disclosure provides an access node for transferring and/or assigning network passwords. The access node includes a first interface for sending and receiving communication of a first type to and from a first node operating in a wireless local area network (WLAN). The access node also includes a second interface for sending and receiving communication of a second type to and from a second node in a mobile network, such as a GSM/GPRS network. The access node further includes a short messaging service (SMS) module for sending and receiving. SMS messages to the second node carrying an OTP allocated. The access node also includes a mechanism to verify a precondition before the OTP is sent to the second node.

First claim

The invention claimed is:

1. A non-transitory computer-readable storage medium that contains instructions, which when executed, cause one or more processors to perform operations comprising:
sending a first message from a mobile unit to an access node to receive a password to access a wireless local area network (WLAN), wherein the mobile unit is to operate in a mobile network, and the access node has a unique identifier and is to provide access in the WLAN; and
receiving the password from the access node at the mobile unit to access the WLAN.

2. The storage medium of claim 1 , wherein the password is a one-time password (OTP).

3. The storage medium of claim 1 , wherein said receiving includes receiving a second message at the mobile unit including the password.

4. The storage medium of claim 3 , wherein the one or more processors are further caused to perform receiving a third message at the mobile unit from the access node, the third message including the unique identifier of the access node, wherein said sending is performed responsive to said receiving the third message.

5. The storage medium of claim 4 , wherein at least one of the first message, the second message or the third message is a short messaging service (SMS) message.

6. The storage medium of claim 1 , wherein the access node is a subscriber of the mobile network and the identifier is an Mobile Station International Subscriber Directory Number (MSISDN) number of the access node.

7. The storage medium of claim 1 , wherein the mobile network includes at least one of a global system mobile (GSM) network or a code division multiple access (CDMA) network.

8. A device to operate in a mobile network, the device comprising:
an interface to exchange messages in the mobile network, wherein the interface is to:
send a first message from a mobile unit to an access node to receive a password to access a wireless local area network (WLAN), wherein the mobile unit is to operate in a mobile network, and the access node has a unique identifier and is to provide access in the WLAN; and
receive the password from the access node at the mobile unit to access the WLAN.

9. The device of claim 8 , wherein the password is a one-time password (OTP).

10. The device of claim 8 , wherein the interface is to receive a second message including the password.

11. The device of claim 10 , wherein the interface is to receive a third message at the mobile unit from the access node, the third message including the unique identifier of the access node, wherein the interface is send the first message after receiving the third message.

12. The device of claim 11 , wherein at least one of the first message, the second message or the third message is a short messaging service (SMS) message.

13. The device of claim 8 , wherein the access node is a subscriber of the mobile network and the identifier is an MSISDN number of the access node.

14. The device of claim 8 , wherein the mobile network includes at least one of a global system mobile (GSM) network or a code division multiple access (CDMA) network.

15. The device of claim 8 , wherein the interface is to send the second message using the identifier.

16. A method to access a wireless local area network (WLAN), the method comprising:
sending a first message from a mobile unit to an access node to receive a password to access the WLAN, wherein the mobile unit is to operate in a mobile network, and the access node has a unique identifier and is to provide access in the WLAN; and
receiving the password from the access node at the mobile unit to access the WLAN.

17. The method of claim 16 , wherein the password is a one-time password (OTP).

18. The method of claim 16 , wherein said receiving includes receiving a second message at the mobile unit including the password.

19. The method of claim 18 , further comprising receiving a third message at the mobile unit from the access node, the third message including the unique identifier of the access node, wherein said sending is performed responsive to said receiving the third message.

20. The method of claim 19 , wherein at least one of the first message, the second message or the third message is a short messaging service (SMS) message.

21. The method of claim 16 , wherein the access node is a subscriber of the mobile network and the identifier is an MSISDN number of the access node.

22. The method of claim 16 , further comprising gaining access to the WLAN through the mobile unit using the password.

23. The method of claim 16 , wherein the mobile network includes at least one of a global system mobile (GSM) network or a code division multiple access (CDMA) network.

24. The method of claim 16 , wherein said sending includes sending the first message using the identifier.
