Abstract

According to one embodiment of the present invention, a method for authenticating access authority for a specific resource in a wireless communication system is provided. The method is performed by a terminal and includes the steps of: receiving from a server, an operation for a specific object of a terminal, a specific object instance, or a resource (hereinafter referred to as “operation target”) belonging to the specific object instance; and checking whether an access authority for the operation target is granted for a server based on access authority information associated with the operation target. The method further includes a step of determining whether at least one resource belonging to the operation target supports the operation based on one or both of the operation and the operation target when the access authority for the operation target is granted, and the access authority information associated with the operation target can be specified for a specific object instance to which the one or more resources belong.

Claims

1. A method for authorizing, by a terminal, an access right for a resource in a wireless communication system, the method comprising:

receiving, from a server, an operation for an operation target, the operation target being an object instance or the operation target being a resource belonging to the object instance; and

authorizing the server to perform the received operation for the operation target by;

checking whether to perform the received operation based on access right information associated with the operation target is granted for the server,

determining, based on the access right information, whether the operation target supports the received operation when the terminal determines that the server is granted authorization to perform the received operation, and

performing the received operation based on at least one of a type of the received operation and a type of the operation target when the terminal determines that the operation target supports the received operation,

wherein the access right information associated with the operation target is specified for the object instance to which the resource belongs when the operation target is the resource.

2. The method according to claim 1, wherein the received operation is performed only when the received operation and/or the operation target corresponds to a predetermined operation and/or a predetermined operation target, respectively.

3. The method according to claim 1, wherein a supportable operation is defined according to the type of the operation target.

4. The method according to claim 3, further comprising:

when the received operation is not supported for the operation target, transmitting, to the server, a response for notifying the server that the received operation is not supported.

5. The method according to claim 1, wherein, when the terminal has only a single server account, the terminal checks that the server is granted for performing the received operation if the server corresponds to the single server account.

6. The method according to claim 5, wherein the server has an access right for all operations.

7. The method according to claim 1, wherein the method further comprises:

when the access right for the operation target is not granted, transmitting, to the server, a response for notifying the server that access is rejected is transmitted.

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

when the terminal checks that the server is granted for performing the received operation, the received operation is a predetermined type of operation and the operation target is a specific object instance, performing the received operation for the specific object instance without determining whether the at least one resource belonging to the operation target supports the received operation.

9. The method according to claim 1, wherein the access right information associated with the operation target for the server is obtained from an access control object instance associated with the operation target.

10. The method according to claim 7, wherein the transmitting of the response comprises notifying the server of an operation target causing an access rejection.

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

checking access right information for the specific object instance to which the resource belongs if the operation target is the resource.
