Abstract: A method and apparatus for providing an edge transfer according to the movement of a device are provided. The method includes receiving a handover decision and handover information from a network, when a device performs the handover and a network function virtualization instance of the source edge is transferred to the target edge. The method then transfers an M2M service instance of the source edge to an M2M edge node.

Abstract: A method and apparatus of managing information are configured to replace parts of an Internet of Things (IoT) device in a machine-to-machine (M2M) system. A method for operating a first device may include receiving a first message for requesting registration of at least one resource related to a second device including a plurality of parts, generating at least one resource comprising information on the plurality of parts, and transmitting, to the second device, a second message for recommending replacement of a part corresponding to a condition for replacing at least one of the plurality of parts when the condition is satisfied.

Abstract: 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.

Abstract: The present disclosure relates to detecting an abnormal behaviour in a machine-to-machine (M2M) system. A method for operating a first device may include receiving, from a second device, a request message related to a detection of an abnormal behaviour in a target device and, when the abnormal behaviour is detected, transmitting a notification of the occurrence of the abnormal behaviour to the second device. The abnormal behaviour may be detected based on information that is expected to be received or is received by the first device from the target device.

Abstract: 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.

Abstract: The present invention relates to a method of performing group management in a machine-to-machine (M2M) system. Herein, the group management method may include controlling a group member included in a group based on a group resource.

Abstract: 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.

Abstract: 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, offloading the source resource for which the offloading is requested. An offloaded resource is then generated using the offloaded source resource. Herein, the offloaded resource includes synchronization modes designating synchronization methods with the offloaded source resource as offloaded attributes.

Abstract: A liveness check in a machine-to-machine (M2M) system is provided. A method for operating an M2M device includes generating a resource including information on a liveness check for a local device and confirming whether a probe signal for the liveness check is received from the local device. The liveness status of the local device is determined based on whether the probe signal is received.
