Abstract
A machine-to-machine (M2M) gateway (GW) includes reachability, addressing, and repository (RAR) capability. The GW maintains a local mapping table and local device application repository, performs data aggregation, address/name translation, provides event reporting and establishes GW reachability and wake-up time. The GW supports requests from M2M applications or other capabilities within the GW, and from a network and application (N&A) domain RAR. The GW may include an M2M device and M2M gateway management (MDGM) capability that receives management requests for an M2M device and functions as a network proxy. The MDGM accepts and processes requests from the N&A domain on behalf of the M2M device and performs management functions of the M2M device on behalf of the N&A domain. The MDGM may request the N&A domain for permission to interact with the M2M device, initiate an interaction for device management tasks with the M2M device, and report to the N&A domain.

17. The method of claim 15, further comprising the RAR entity providing a reachability status for an M2M device and updating the reachability status upon a predetermined event comprising at least one of a change in registration information, a wake-up time, and an address.
18. The method of claim 15, further comprising the RAR entity maintaining M2M device registration information and providing a query interface for accessing the M2M device registration information by an authenticated and authorized entity.
19. The method of claim 15, further comprising the MDGM entity requesting a network and application domain for permission to interact with an M2M device to perform device management tasks and performing the device management tasks upon receipt of permission from the network and application domain.
20. The method of claim 15, further comprising the MDGM entity initiating an interaction for device management tasks with the M2M device and informing a network and application domain of results from the interaction for the device management tasks.
