Embodiment Construction

[0040] The development of the OMA protocol described above reflects the gradual evolution of emerging technologies as OMA deals. With the growing interest in M2M, IoT and Internet of Things (WoT) devices the OMALW M2M protocol attempts to provide more constrained device management.

[0041] The LWM2M protocol is different from the aforementioned OMA DM and GwMO protocols. The LWM2M protocol uses a communication protocol with a flatter and simpler resource tree that is more conducive to constrained devices. Data types are simplified and payloads are more efficient. Therefore, the LWM2M protocol is currently incompatible with the OMA DM and GwMO protocols.

[0042] Furthermore, the OMA DM protocol lacks a mechanism to dynamically support the addition of new devices MO. A DDF document completely defines all nodes and their associated functions within the MO, and this DDF document is used by the DM server, DM gateway and DM client to construct their corresponding management tre...

Abstract

Interworking LWM2M and OMA DM protocols is disclosed. A new DDF MO enables adding LWM2M object definitions to DM Servers and Gateways. This MO allows a DM Server/Gateway to accept newly defined MOs, such as LWM2M Object definitions. New procedures are defined for registering DDF documents to the newly created DDF MO. A new registration interface is added in the GwMO protocol to allow an LWM2M Server to register end devices to a DM gateway. A protocol translation mechanism bridges the gap between non-RESTful to RESTful protocols, such as OMA DM and/or GwMO to LWM2M.

Description

[0001] Cross References to Applications [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 027,395, filed July 22, 2014, the disclosure of which is incorporated herein by reference as if set forth in its entirety herein. Background technique [0003] The Open Mobile Alliance (OMA) has developed several protocols for device management in networks, including the OMA Device Management (DM) protocol, the OMA Gateway Management Object (GwMO) protocol, and the OMA Lightweight Machine-to-Machine (LWM2M) protocol. The OMA DM protocol can be used to manage standalone devices (such as mobile devices) in the network. The OMA GwMO protocol can be used to manage end devices behind a gateway, while OMA LWM2M can be used to manage constrained machine-to-machine (M2M) or Internet of Things (IoT) devices. [0004] figure 1 The general architecture of the OMA DM protocol is shown. DM server 102 (also sometimes referred to as a management server) is the m...
