The method comprises the steps of: receiving, by a fist M2M entity, a request message relating to an operation for a specific resource from a second M2M entity; determining whether or not the first M2M entity has the specific resource; and if the first M2M entity does not have the specific resource, determining whether or not an integrity code is included in the request message, and if the integrity code is included in the request message, delivering the request message to a third M2M entity, or the method may comprise the steps of: if the first M2M entity has the specific resource, determining whether or not the first M2M entity has a registration relation with the second M2M entity; and if the first M2M entity has no registration relation with the second M2M entity, performing verification on the integrity code included in the request message.
Abstract:
A method for allocating a user-specific application identifier in a wireless communication system, according to one embodiment of the present invention, is carried out by an M2M apparatus and may comprises the steps of: receiving user information from a user; transmitting, to a peer M2M device, a request message including a user-specific token and an application identifier based on the user information, to allocate the user-specific application identifier; and receiving, from the peer M2M device, a reply message including the user-specific token and the user-specific application identifier which has been allocated based on the application identifier.
Abstract:
Disclosed is a method for notifying an attribute of an original resource of one entity to another entity in a wireless communication system according to one embodiment of the present invention. The method may comprise the steps of: receiving an update request for an ‘announcedAttribute’ attribute comprising a list of pre-notified attributes included in the original resource, for notifying a specific attribute of the original resource, wherein each attribute in the original resource is set to one of a mandatory announced (MA) type that should be notified mandatorily, an optional announced (OA) type that is optionally notified according to the contents of the specific attribute in the original resource, and a not announced (NA) type that is not notified; determining whether the specific attribute is the OA type; and notifying the specific attribute to all notified resources of the original resource if the specific attribute is the OA type.
Abstract:
The present invention relates to a method for authorizing a specific operation of a specific resource in a wireless communication system, and comprises receiving, from a requesting M2M device, a request for a specific operation of a specific resource, the operation request including an identifier of the requesting M2M device and the identifier being associated with an M2M service subscription resource derived using a credential of the requesting M2M device; searching the M2M service subscription resource using the identifier, and determining whether the requesting M2M device is authorized for a type of the specific resource using the M2M service subscription resource.
Abstract:
A method for location based access control in a wireless communication system is disclosed. The method comprises receiving, from an originating device, a request for access to a specific resource associated with location constraints, the location constraints being related to circular description or country description, checking whether location information of the originating device is present, acquiring the location information of the originating device according to type of the location constraints when the location information of the originating device is not present, and performing access control based on the acquired location information.
Abstract:
One embodiment of the present invention discloses a method for handling notification messages for applying a group policy to a notification subscription service in a wireless communication system. The method is carried out by a first M2M device and comprises the steps of: receiving a plurality of notification messages; determining whether a group subscription ID matching a group subscription ID that has been pre-saved on the first M2M device is included in the plurality of notification messages which have been received, wherein the group subscription ID indicates a group policy applied to a subscription service for notification messages for member resources belonging to a specific group; and aggregating notification messages containing the group subscription ID that matches the pre-saved group subscription ID, and applying the group policy corresponding to the group subscription ID to the aggregated notification messages.
Abstract:
A method for processing a request through a polling channel in a wireless communication system is provided according to one embodiment of the present invention. 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.
