LWM2M SERVER DEVICE, LWM2M CLIENT DEVICE, AND METHODS THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18034741 titled 'LWM2M SERVER DEVICE, LWM2M CLIENT DEVICE, AND METHODS THEREOF

Simplified Explanation

The abstract describes a device and method for managing a group of Lightweight Machine to Machine (LwM2M) devices using the Message Queueing Telemetry Transport (MQTT) protocol. The device, called the LwM2M server device, can perform management operations on LwM2M clients that meet a certain criterion. It can identify a group management topic that is not specific to any particular LwM2M endpoint. The device can then publish a group management message to an MQTT server, specifying the group management topic and the operation to be performed.

  • LwM2M server device with integrated MQTT client for group management of LwM2M devices
  • Processing circuitry to determine when a management operation is needed on LwM2M clients
  • Identification of a group management topic that is not specific to any particular LwM2M endpoint
  • Publishing of a group management message to an MQTT server, specifying the topic and operation

Potential Applications

  • IoT device management: This technology can be used to efficiently manage a large number of IoT devices by performing group management operations on them.
  • Firmware updates: The LwM2M server device can use this technology to send firmware update commands to a group of LwM2M clients, simplifying the process of updating device firmware.
  • Configuration management: Group management messages can be used to configure settings on multiple LwM2M devices simultaneously, reducing the time and effort required for configuration tasks.

Problems Solved

  • Scalability: The LwM2M server device allows for efficient management of a large number of LwM2M devices by performing group management operations.
  • Simplified management: The use of group management topics and messages simplifies the process of managing multiple LwM2M devices, reducing the complexity and effort required.
  • Flexibility: The technology allows for the identification of LwM2M clients based on criteria, enabling targeted management operations on specific groups of devices.

Benefits

  • Efficient management: The technology enables the management of multiple LwM2M devices in a more efficient and scalable manner.
  • Simplified operations: Group management messages and topics simplify the process of performing management operations on multiple devices, reducing complexity and effort.
  • Targeted management: The ability to identify LwM2M clients based on criteria allows for targeted management operations on specific groups of devices, improving flexibility and control.


Original Abstract Submitted

Group management of LwM2M devices over MQTT A Lightweight Machine to Machine (LwM2M) server device is disclosed that is operable to run a LwM2M server and a Message Queueing Telemetry Transport (MQTT) client. The LwM2M server device comprises processing circuitry configured to cause the LwM2M server device to determine () that a LwM2M management operation should be performed on LwM2M clients fulfilling a criterion, and to identify () a LwM2M group management topic corresponding to the criterion, a LwM2M group management topic comprising a topic within a LwM2M namespace that is nonspecific to a particular LwM2M endpoint. The processing circuitry is further configured to cause the LwM2M server device to publish () a group management message to an MQTT server, the group management message specifying the identified LwM2M group management topic and the management operation to be performed. Also disclosed are a LwM2M client device and associated methods.
