Abstract

The disclosure is related to a method of providing M2M data to an unregistered user terminal. The method may include receiving a request message from a first user terminal registered at the M2M service server to provide predetermined data collected from a M2M device to a second user terminal, determining whether the second user terminal is a subscriber of the M2M service server, temporary registering the second user terminal when the second user terminal is not a subscriber of the M2M service server, and providing the predetermined data to the second user terminal.

Claims

1. A method of providing data collected from a machine to a machine (M2M) device by a M2M service server to an unregistered user terminal wherein the M2M service server including at least one processor, at least one memory, and a communication circuit, the method comprising:

receiving, through the communication circuit, a request message from a first user terminal registered at the M2M service server to provide predetermined data collected from a M2M device to a second user terminal;

determining, by the at least one processor, whether the second user terminal is a subscriber of the M2M service server;

temporary registering the second user terminal and store registration information in the at least one memory when the second user terminal is not a subscriber of the M2M service server; and

providing the predetermined data stored in the at least one memory to the second user terminal through the communication circuit,

wherein the providing the predetermined data to the second user terminal includes modifying a resource of the M2M service server to temporarily register the second user terminal, and

wherein the method further comprises;

assigning a temporal identification to the second user terminal;

adding the temporal identification of the second user terminal in an <

applications>

resource;

adding the temporal identification of the second user terminal in an <

accessRights>

to allow the second user terminal to access the predetermined data; and

modifying a <

subscriptions>

resource to transmit a notification message to the second user terminal when the predetermined data is ready to be provided.

2. The method of claim 1, wherein:

the temporary registering includes transmitting a temporal registration request message to the second user terminal through a first communication service platform of the first user terminal and a second communication service platform of the second user terminal; and

performing the temporary registering upon receipt of a registration request message from the second user terminal.

3. The method of claim 2, wherein:

the temporal registration message is an session initiation protocol (SIP) message that includes at least one of information on an address of the second communication service platform, a temporary ID of the second user terminal, and an encryption key.

4. The method of claim 2, wherein the transmitting a temporal registration request message includes:

determining domain information on a second communication network of the second user terminal from an associated server; and

transmitting the temporal registration request message to the second user terminal using the determined domain information of the second communication network.

5. The method of claim 2, wherein the temporary registering the second user terminal includes:

generating an encryption key for sharing the control right with the second user terminal;

creating a temporal registration request message including the generated encryption key;

transmitting the temporal registration request message to the second user terminal; and

performing an authentication process upon receipt of a registration request message from the second user terminal.

6. The method of claim 5, wherein the performing an authentication process includes:

comparing the generated encryption key with an encryption key included in the registration request message from the second user terminal.

7. The method of claim 1, wherein the providing the predetermined data to the second user terminal includes:

transcoding the predetermined data based on information on the second user terminal included in the temporal registration request message.

8. The method of claim 7, comprising:

transmitting a notification message to the second user terminal to inform that the predetermined data is ready to be provided.

9. The method of claim 1, comprising:

calculating a fee of providing the predetermined data to the second user terminal; and

requesting a server to perform an associated accounting process based on the calculated fee.

10. The method of claim 9, comprising;

charging at least one of the first user terminal and the second user terminal based on the calculated fee for providing the predetermined data to the second user terminal.

11. A machine to machine (M2M) service server of providing data collected from at least one M2M device to an unregistered user terminal, the server comprising:

at least one memory, a communication circuit, and at least one processor,

wherein the at least one processor is configured to;

receive, through the communication circuit, a request message from a first user terminal registered at the M2M service server to provide predetermined data collected from a M2M device to a second user terminal;

determine whether the second user terminal is a subscriber of the M2M service server;

temporarily register the second user terminal and store registration information in the at least one memory when the second user terminal is not a subscriber of the M2M service server; and

provide the predetermined data to the second user terminal through the communication circuit,

wherein the at least one processor is configured to;

assign a temporal identification to the second user terminal;

add the temporal identification of the second user terminal in an <

applications>

resource of a <

scl>

resource of the M2M service server;

adding the temporal identification of the second user terminal in an <

accessRights>

resource of the <

scl>

resource of the M2M service server to allow the second user terminal to access the predetermined data and

modifying a <

subscriptions>

resource of the <

scl>

resource of the M2M service server to transmit a notification message to the second user terminal when the predetermined data is ready to be provided.

12. The M2M service server of claim 11, wherein the at least one processor is configured to:

transmit a temporal registration request message to the second user terminal through a first communication service platform of the first user terminal and a second communication service platform of the second user terminal; and

perform the temporary registering upon receipt of a registration request message from the second user terminal.

13. The M2M service server of claim 12, wherein:

the temporal registration message is an session initiation protocol (SIP) message that includes at least one of information on an address of the second communication service platform, a temporary ID of the second user terminal, and an encryption key.

14. The M2M service server of claim 12, wherein the at least one processor is configured to:

determine domain information on a second communication network of the second user terminal from an associated server; and

transmit the temporal registration request message to the second user terminal using the determined domain information of the second communication network.

15. The M2M service server of claim 12, wherein the at least one processor is configured to:

generate an encryption key for sharing the control right with the second user terminal;

create a temporal registration request message including the generated encryption key;

transmit the temporal registration request message to the second user terminal; and

perform an authentication process upon receipt of a registration request message from the second user terminal.

16. The M2M service server of claim 11, wherein the at least one processor is configured to:

transcode the predetermined data based on information on the second user terminal included in the temporal registration request message;

transmit a notification message to the second user terminal to inform that the predetermined data is ready to be provided.

17. The M2M service server of claim 11, wherein the at least one processor is configured to:

calculate a fee of providing the predetermined data to the second user terminal; and

request a server to perform an associated accounting process based on the calculated fee in order to charge at least one of the first user terminal and the second user terminal based on the calculated fee for providing the predetermined data to the second user terminal.
