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:
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 in which a personal network element (PNE) forming a PN requests a converged personal network service (CPNS) to set up a new personal network (PN) on the basis of PN usage information. The method is performed by the PNE and includes: transmitting, to a PN gateway (PN GW), a message requesting the generation of PN usage information on a currently set PN; and receiving a generation response message including the result of generating the PN usage information corresponding to the generation request message. The PN usage information is created by the CPNS server on the basis of the generation request message and is stored in a PN usage information list of the CPSN. The PN usage information includes a PN usage information index, a PN alias, an expiry, a PN identifier (ID), a PN GW ID, and a PNE ID. The method further includes: transmitting, to the PN GW, a message requesting the setting of a PN using PN usage information corresponding to a new PN, in order to set the new PN and not the currently set PN; and receiving, from the PN GW, a message responding to setting the PN including a response to the PN setting request message, wherein a PN inventory of the CPNS server may be updated by the CPNS on the basis of selected PN usage information.
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:
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:
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:
According to one embodiment of the present invention, a method for processing a request message in a wireless communication is disclosed, and the method is performed by a first M2M device and comprises the steps of: receiving a request message related to a specific resource type from a second M2M device; determining whether the specific resource type is supported; searching for another M2M device supporting the specific resource type if the specific resource type is not supported; processing the request message so as to transfer the processed request message to a third M2M device if the third M2M device supporting the specific resource type is discovered according to the searched result, wherein an operation related to the request message is performed by the third M2M device instead of the first M2M device; receiving a response message including the processed result of the request message from the other device; and processing the received response message so as to transfer the processed response message to a transmission device.
Abstract:
The present invention relates to a method for enabling a machine-to-machine (M2M) gateway to measure the position of an M2M device, and an apparatus therefore, and the method includes the steps of: receiving a request for generating a first resource representing the way of obtaining positional information form a first M2M device; if the generation request contains the information for indicating commonly based positional measurement, determining the device closest to the first M2M device; and setting the positional information of the closest device as the positional information for the first m2M device, wherein if the M2M gateway does not have network topological information, or at least one M2M device connected to the m2M gateway does not have positional information, the M2M topological information, and the at least one M2M device connected to the M2M gateway has positional information, the device having the minimum number of hops from the first M2M device among the at least one M2M device is determined as the closest device, and the first resource represents a data structure capable of being uniquely addressed using address information.
