M2M Device Grouping for Wireless Network Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of machine-to-machine (M2M) devices in wireless communication systems leads to significant communication overhead and congestion, as each device requires individual management, which is inefficient and resource-intensive.
Innovation Solution
The technique involves aggregating M2M devices into groups based on received information, such as location or traffic characteristics, and using a group identifier to multicast data, reducing the need for individual messages and thereby minimizing overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual management is used for each M2M device, then device management coverage is complete, but communication overhead increases significantly
Solution Approach 1:
The patent groups multiple M2M devices into a single M2M group, merging individual device management into group-level management. The base station communicates with the M2M group using a group identifier instead of addressing each device individually, thereby reducing communication overhead while maintaining management coverage through group-based control mechanisms
2Adaptability or versatility
If a large number of M2M devices are deployed, then system functionality and coverage are enhanced, but network congestion increases
Solution Approach 1:
Multiple M2M devices are merged into a single M2M group identified by a group identifier. The base station transmits data to the entire group using this single identifier rather than sending individual messages to each device, significantly reducing network traffic and congestion while supporting large-scale device deployment
3Reliability
If individual messages are sent to each M2M device, then message delivery accuracy is ensured, but the number of messages required increases
Solution Approach 1:
The patent consolidates multiple individual messages into a single group message by using an M2M group identifier. The base station sends one message addressed to the group identifier, which is then delivered to all devices in the M2M group, maintaining delivery accuracy while reducing the total message count from N individual messages to 1 group message
Solution Approach 2:
The M2M group identifier serves multiple functions simultaneously: it identifies the group as a communication target, routes messages to all group members, and enables group-level management operations. This universal identifier replaces multiple individual device identifiers, reducing message overhead while maintaining delivery reliability

AI summary
Techniques for machine-to-machine device management are described. In some embodiments a method may comprise receiving information from a plurality of machine-to-machine (M2M) devices over one or more wireless channels, aggregating two or more of the M2M devices as an M2M group based on the received information, and multicasting data to the M2M devices in the M2M group over the one or more wireless channels. Other embodiments are described and claimed.
