摘要： Provided are an IoT device and an IoT communication method. The IoT device may: be connected to a server via NAT; execute a first session for service connection; and execute a second session for calculating a particular keep-alive value corresponding to a period in which an IP address mapped by the NAT expires. The present invention can minimize transmission of a keep-alive value of an IoT device, enables an IoT device to share a particular keep-alive value with other IoT devices, and thus can minimize a network load which may be caused by a keep-alive value of an IoT communication device.

摘要： Provided is a resource label retrieval method in a one M2M system. A resource information retrieval method according to an embodiment of the present disclosure includes retrieving, by the M2M system, labels of resources when a label retrieval request regarding resources is received, determining, by the M2M system, whether to return an interworking information label on which information regarding data interworking with another system is recorded, among the retrieved labels of the resources, and returning a label of a resource retrieved according to a result of the determining. Accordingly, when retrieval of a resource label is requested, an interworking information label is selectively/restrictively returned based on a type of an AE which requests or a type of a retrieval request, so that a service error caused by provision of unnecessary information can be prevented and information security can be strengthened.

摘要： A method for validating the validity of a group member of a virtual resource is provided. A method for validating the validity of a group according to an embodiment of the present invention obtains parent resource type information of a resource designated by a group member ID included in a group generation request and validates the validity of the group by using the obtained parent resource information. Accordingly, the validity of a virtual resource as a group member can be validated.
