Embodiment Construction

[0031] In the following description, for purposes of illustration and not limitation, specific details are set forth, such as specific architectures, interfaces, techniques, etc., in order to provide a thorough understanding. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description with unnecessary detail. Throughout this specification, the same reference numerals refer to the same or similar elements.

[0032] The present teaching particularly relates to various devices capable of supporting at least IP-based communications in short-range communications, such as refrigerators, lamps, various metering devices, and the like. From a home networking standpoint, that means these devices can support some short-range technology, such as Wi-Fi. The market for many traditional IoT devices relies on non-standard or de facto standards for communication and application stacks. However, the market has rapidly...

Abstract

A method (30) performed in a client device (16) is provided for managing constrained devices (14a, 14b, 14c), which to at least some extent fail to support a Lightweight Machine to Machine, LWM2M, protocol. The client device (16) is compatible with a LWM2Mprotocol for communicating with a LWM2M server (17) and comprises a LWM2Mcontroller object (22) for management of any discovered constrained device (14a, 14b, 14c). The method (30) comprises discovering (31) one or more constrained devices (14a, 14b, 14c); creating (32), for each discovered constrained device (14a, 4b, 14c), a respective LWM2M connected device object (23), wherein the LWM2M controller object (22) points at the one or more created LWM2Mconnected device 10 objects (23); and exposing (33) the LWM2M controller object (22) tothe LWM2M server (17). A method (40) in a server device (17), client device (16), server device (17), computer programs and computer program products are also provided.

Description

technical field [0001] The technology disclosed herein relates generally to the field of data communications, and more particularly to methods of client device management of constrained devices, client devices, methods of server device management of constrained devices, server devices, and related computer programs and computer program products . Background technique [0002] Machine-to-machine (M2M) is a concept including devices (for example, sensors and so-called smart devices) that communicate with remote applications such as Internet servers using a network. Such communication may eg be used for monitoring and control purposes. The Internet of Things (IoT) refers to a network of objects ("things") with network connectivity, and M2M can be considered a component of IoT. Together, M2M / IoT covers a large number of devices that use short-range technologies (e.g., Bluetooth or WiFi) as well as long-range technologies (e.g., radio access technologies such as 3G or 4G) based...
