Abstract

Methods and devices for initial bootstrap of a user terminal are provided. The user terminal transmits at least one first message to an initial bootstrap server. The first message includes device management capability information for the user terminal. The initial bootstrap server selects a device management protocol to be used by the user terminal and sends the selected device management protocol to the user terminal in at least one second message.

Claims

1. A method for initial bootstrap of a user terminal, the method comprising:

receiving, at an initial bootstrap server, at least a first message from the user terminal, the at least one first message including device management capability information for the user terminal; and

sending, in response to the received at least one first message, at least one second message to the user terminal, the at least one second message including device management protocol information, the device management protocol information being indicative of a device management protocol to be used by the user terminal.

2. The method of claim 1, wherein the device management protocol information includes at least one of device management protocols supported by the user terminal, a manufacturer name, and a device model identification for the user terminal.

3. The method of claim 1, wherein the at least one of the first and second messages is a hyper-text transfer protocol message.

4. The method of claim 1, wherein the second message includes bootstrapping information associated with a device management protocol identified in the device management protocol information.

5. The method of claim 1, further comprising:

initiating the device management protocol identified in the second message using bootstrap information also included in the second message.

6. The method of claim 1, further comprising:

selecting the device management protocol from a plurality of device management protocols based on the device management capability information included in the first message.

7. The method of claim 1, further comprising:

opening a pinhole through a first port of the initial bootstrap server in response to the first message; and

wherein

the sending step sends the at least one second message to the user terminal through the pinhole in the first port.

8. The method of claim 7, wherein the at least one second message includes device management protocol information or subscription information.

9. A method for initial bootstrap of a user terminal, the method comprising:

transmitting, by the user terminal, at least one first message to an initial bootstrap server, the first message including device management capability information for the user terminal; and

receiving, at the user terminal, at least one second message from the initial bootstrap server, the at least one second message including device management protocol information, the device management protocol information being indicative of a device management protocol to be used by the user terminal.

10. The method of claim 9, wherein the device management protocol information includes at least one of device management protocols supported by the user terminal, a manufacturer name, and a device model identification for the user terminal.

11. The method of claim 9, wherein the at least one of the first and second messages is a hyper-text transfer protocol message.

12. The method of claim 9, wherein the second message includes bootstrapping information associated with a device management protocol identified in the device management protocol information.

13. The method of claim 9, further comprising:

initiating the device management protocol identified in the second message using bootstrap information also included in the second message.

14. The method of claim 9, wherein the device management protocol is one of a plurality of device management protocols selected by the initial bootstrap server based on the device management capability information included in the first message.

15. A user terminal for accessing wireless network, the user terminal comprising:

a device management module configured to transmit at least one first message to an initial bootstrap server, the first message including device management capability information for the user terminal, and the device management module being further configured to receive at least one second message from the initial bootstrap server, the at least one second message including device management protocol information, the device management protocol information being indicative of a device management protocol to be used by the user terminal.

16. The terminal of claim 15, wherein the device management protocol information includes at least one of device management protocols supported by the user terminal, a manufacturer name, and a device model identification for the user terminal.

17. The terminal of claim 15, wherein the at least one of the first and second messages is a hyper-text transfer protocol message.

18. The terminal of claim 15, wherein the second message includes bootstrapping information associated with a device management protocol identified in the device management protocol information.

19. The terminal of claim 15, wherein terminal initiates the device management protocol identified in the second message using bootstrap information also included in the second message.

20. The terminal of claim 15, wherein the device management protocol is one of a plurality of device management protocols selected by the initial bootstrap server based on the device management capability information included in the first message.
