The method is performed by a first apparatus, and may comprise the steps of: transmitting to a second apparatus a retrieve response for a polling channel, including a first request which has been received from a third apparatus; receiving, from the second apparatus, a second request including a first response corresponding to the received first request; verifying whether a request identifier of the first response and a request identifier of the received first request are the same or not; and if the request identifier of the first response and the request identifier of the received first request are the same, transmitting the first response to the third apparatus.
Abstract:
A method for re-arrangement of a group resource of an M2M device arranged according to a hierarchical tree structure is disclosed in accordance with one embodiment of the present invention. The method is performed by a first M2M device which owns a first group resource, and the method comprises the steps of: receiving, from a second M2M device, a specific request message for the first group resource; determining whether it is necessary to transfer at least one member of the first group resource as a member of a group resource of another M2M device; determining, in order to transfer the at least one member as a member of the group resource of the another M2M device, whether to use a group resource existing in the another M2M device or whether to generate a new group resource in the another M2M device; and if a new group resource is generated in the another M2M device, adding the at least one member as a member of the new group resource, wherein the first group resource is added as a member of the new group resource if the another M2M device is higher than the first M2M device in the hierarchical tree structure, and the new group resource is added as a member of the first group resource if the another M2M device is lower than the first M2M device in the hierarchical tree structure.
Abstract:
A method for processing a request message in a wireless communication system according to one embodiment of the present invention is performed by a first M2M device and comprising the steps of: receiving the request message directly from a transmission device; determining whether the transmission device is registered in the first M2M device; determining whether the request message is for handover setup if the transmission device is not registered in the first M2M device; storing handover information contained in the request message if the request message is for handover setup; updating registration information related to the transmission device according to the handover information; and transmitting a processing result regarding the request message to the transmission device.
Abstract:
According to one embodiment of the present invention, a method for processing a notification message for applying a group policy to a notification subscription service in a wireless communication system is performed by a first M2M device, and comprises the steps of: receiving a plurality of notification messages; determining whether a group subscription ID matching with a group subscription ID pre-stored in the first M2M device is included in the plurality of received notification messages; indicating, by the group subscription ID, a group policy applied to the subscription service for the notification messages for member resources belonging to a specific group; and aggregating the notification messages in which the group subscription ID matching with the pre-stored group subscription ID is included, and applying, to the aggregated notification messages, the group policy corresponding to the group subscription ID.
Abstract:
A method for processing request messages between heterogeneous systems in a wireless communication system, the method being performed by a gateway device and possibly comprising the steps of: receiving an advertisement message on the services of a first node from the first node belonging to a first system; in case the advertisement message comprises an indicator that the services are shared with a second system, generating resources corresponding to the shared services and a resource for access control for the resources corresponding to the shared services; receiving a request message for retrieving information on the generated resources from a second node of the second system; if the second node has an access right to the retrieval, transmitting the information on the generated resources to the second node; receiving, from the second node, a request message for generating a resource, which corresponds to a service to be called selected from the information on the generated resources, as a child resource of the generated resources; and checking an access right for the generation of the child resource.
Abstract:
A method for forwarding a message in a wireless communication system according to an embodiment of the present invention is performed by an M2M device, and comprises the steps of: receiving a request message; checking whether the M2M device is a recipient of the request message, using a particular parameter included in the request message; when the M2M device is not a recipient of the request message, checking whether only one registrant M2M device exists other than the M2M device which has received the request message within one hop of the M2M device, wherein the registrant M2M device is in an M2M device in which one or more other M2M devices can be registered; and when the only one registrant M2M device is present within the one hop, forwarding the request message to the only one registrant M2M device, wherein the particular parameter may be a “to” parameter.
Abstract:
The present invention relates to a method for the notification of a resource subscription in a machine-to-machine (M2M) system and devices for same, the method comprising the steps of: detecting a change in the resources to subscribe to comprising a subscription resource as a child resource; generating a notification message including a value indicating the event category of the change in accordance with the second attribute information configured in the subscription resource; and determining if a reception device is reachable on the basis of the scheduling information configured in a scheduling resource for an M2M device and the scheduling information configured in a scheduling resource for the reception device, wherein: if the reception device is determined to be reachable on the basis of the scheduling information, the notification message is immediately transmitted to the reception device; and if the reception device is determined to be unreachable on the basis of the scheduling information, the notification message is processed by the M2M device according to the value of the first attribute information configured in the subscription resource, and the processed notification message is transmitted to the reception device after the reception device is recovered to a reachable state.
Abstract:
The present invention relates to a method for processing notification messages in a machine-to-machine (M2M) system and devices for same, the method comprising the steps of: processing by an M2M device one or more notification messages; and transmitting the processed notification message(s), wherein: the one or more notification messages are generated as an originator device detects a change in the resources to subscribe to comprising, as a child resource, a subscription resource configured in the originator device; the one or more notification messages comprise implementation information configured based on the policy information configured in the originator device for the processing of the one or more notification messages; the one or more notification messages are processed based on the implementation information; the one or more processed notification messages are transmitted comprising the implementation information; and the subscription resource and the resources to subscribe to exhibit a data structure uniquely addressable by using a unique address.
