    摘要: A method for operating a machine-to-machine (M2M) device in an M2M system includes generating a request message including information associated to deletion of a resource, the deletion being performed in response to an operation, and transmitting the request message to a counterpart M2M device. The information includes at least one of information notifying that the resource is deleted in response to the operation, information indicating the resource, information indicating at least one operation that is a condition of the deletion, information indicating content of the condition, or information for identifying an entity that performs an operation causing the deletion.

    摘要: A method for performing resource offloading in an M2M system is provided. The method is performed based on an offloaded resource and offloaded attributes. The method includes generating an offloading request message that requests offloading of a source resource. In response to the offloading request message, the method includes offloading the source resource for which the offloading is requested. An offloaded resource is generated using the offloaded source resource. Herein, the offloaded resource includes synchronization modes designating synchronization methods with the offloaded source resource as offloaded attributes.

    摘要: Disclosed herein are a method and procedure for processing protection data for protecting data privacy in an M2M system. According to an embodiment of the present disclosure, an M2M apparatus located in an M2M platform in an M2M system includes a communicator configured to transmit and receive a signal and a processor configured to control the communicator. Herein, the processor generates a resource at a resource generation request for administering data received by the communicator, generates a resource at a resource generation request for storing the data received by the communicator, determines whether the data received by the communicator are protection data, and when the data are determined as protection data, performs data processing for privacy protection.

    摘要: A subscription service including a number of subscriptions possessed by a device is managed in a machine-to-machine (M2M) system. A method for operating a first device may include: transmitting, to a second device, a first message for requesting a new subscription that uses a first resource for managing subscription; receiving, from the second device, a second message for notifying an update of a second resource associated with the new subscription; and identifying a content of the second resource, wherein the first resource may include at least one of a first attribute indicating a number of subscriptions possessed by the first device, a second attribute indicating, among resources to which the first device is subscribing, a number of resources which are updated but not yet retrieved, or a third attribute indicating an access address of a subscribed resource.
