Abstract

The present invention relates to a method and apparatus for modifying a machine-to-machine (M2M) service setting in an M2M system, comprising the steps of: transmitting at least one policy information to at least one device, wherein each of the at least one policy information comprises scope information and condition information; and if the state of an M2M gateway corresponds to a state of which the condition information is indicative, transmitting a first notification indicative of a state change of the M2M gateway to a device of which the scope information is indicative.

Claims

1. A method for notifying a state change by a machine-to-machine (M2M) gateway in an M2M system, the method comprising:

storing policy information by the M2M gateway, wherein the policy information includes limit policy information, the limit policy information includes scope information indicating one or more devices to which the limit policy information is applied, an allowed event category set indicates allowed values for an event category parameter in a request generated by the one or more devices, and condition information indicates a condition under which the limit policy information is applied;

transmitting a second notification to the one or more devices indicated by the stored scope information, the second notification including the allowed event category set; and

when the M2M gateway detects a state change of the M2M gateway indicated by the condition information, transmitting a first notification indicating the state change of the M2M gateway to the one or more devices,

wherein whether the request generated by the one or more devices is transmitted is determined according to whether the request has an event category parameter value within the allowed event category set.

2. The method according to claim 1, wherein the first notification includes identification information corresponding to the policy information, and

wherein when the one or more devices indicated by the scope information receive the first notification, the one or more devices perform an M2M service according to the policy information indicated by the identification information.

3. The method according to claim 1, wherein the policy information includes default policy information, and the default policy information includes a default value for the event category parameter in the request generated by the one or more devices.

4. The method according to claim 3, wherein the default policy information includes a default attribute for the request generated by the one or more devices and a state of the M2M gateway to which the default policy information is applied, and

wherein, when a state of the M2M gateway corresponds to the state of the M2M gateway to which the default policy information is applied and when a specific attribute of the request generated by the at least one of the one or more devices is not designated, the default attribute contained in the default policy information is applied.

5. The method according to claim 1, further comprising:

creating a resource for subscription,

wherein the resource for subscription is created based on the condition information by the M2M gateway.

6. The method according to claim 5, wherein the resource for subscription includes first information about an address of a device to which the notification is transmitted and second information about a criteria value at which the notification is performed, and

wherein creating the resource for subscription includes mapping the scope information to the first information and mapping a value of a state indicated by the condition information to the second information.

7. The method according to claim 1, wherein the condition information includes address information of target information to be monitored and criteria information indicating whether the condition is satisfied.

8. The method according to claim 1, wherein the second notification further includes information indicating a processing scheme for a request.

9. The method according to claim 8, wherein the processing scheme for the request includes at least one of transmitting all pending requests, transmitting the latest request, transmitting a request having an event category parameter of a specific range or a request having a lifespan of a specific range, or processing a request according to the next policy.

10. A machine-to-machine (M2M) gateway of an M2M system, the M2M gateway comprising:

a network interface unit; and

a processor,

wherein the processor is configured to;

store policy information at the M2M gateway, the policy information including limit policy information, the limit policy information including scope information indicating one or more devices to which the limit policy information is applied, an allowed event category set indicating allowed values for an event category parameter in a request generated by the one or more devices, and condition information indicating a condition under which the limit policy information is applied,

transmit, through the network interface unit, a second notification to the one or more devices indicated by the stored scope information, the second notification including the allowed event category set, and

when the M2M gateway detects a state change of the M2M gateway indicated by the condition information, transmit, through the network interface unit, a first notification indicating the state change of the M2M gateway to the one or more devices, and

wherein whether the request generated by the one or more devices is transmitted is determined according to whether the request has an event category parameter value within the allowed event category set.

11. The M2M gateway according to claim 10, wherein the first notification includes identification information corresponding to the policy information, and

wherein when the one or more devices indicated by the scope information receive the first notification, the one or more devices perform an M2M service according to the policy information indicated by the identification information.

12. The M2M gateway according to claim 10, wherein the policy information includes default policy information, and the default policy information includes a default value for the event category parameter in the request generated by the one or more devices.

13. The M2M gateway according to claim 12, wherein the default policy information includes a default attribute for the request generated by the one or more devices and a state of the M2M gateway to which the default policy information is applied, and

wherein, when a state of the M2M gateway corresponds to the state of the M2M gateway to which the default policy information is applied and when a specific attribute of the request generated by the at least one of the one or more devices is not designated, the default attribute contained in the default policy information is applied.

14. The M2M gateway according to claim 10, wherein the processor is further configured to create a resource for subscription, and

wherein the resource for subscription is created based on the condition information by the M2M gateway.

15. The M2M gateway according to claim 14, wherein the resource for subscription includes first information about an address of a device to which the notification is transmitted and second information about a criteria value at which the notification is performed, and

wherein creating the resource for subscription includes mapping the scope information to the first information and mapping a value of a state indicated by the condition information to the second information.

16. The M2M gateway according to claim 10, wherein the condition information includes address information of target information to be monitored and criteria information indicating whether the condition is satisfied.

17. The M2M gateway according to claim 10, wherein the second notification further includes information indicating a processing scheme for a request.

18. The M2M gateway according to claim 17, wherein the processing scheme for the request includes at least one of transmitting all pending requests, transmitting the latest request, transmitting a request having an event category parameter of a specific range or a request having a lifespan of a specific range, or processing a request according to the next policy.
