M2M Group Control Signaling for Wireless Network Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of Machine-to-Machine (M2M) devices in wireless networks leads to excessive control signaling overhead, causing network congestion and inefficient use of resources, as existing techniques like dynamic and persistent scheduling are inadequate for M2M traffic patterns.
Innovation Solution
Implementing enhanced M2M group signaling techniques that customize control message formats and scheduling based on unique M2M traffic characteristics, such as smaller data transmissions and latency tolerance, to reduce control overhead by sharing common and dedicated messages within M2M groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dynamic and persistent scheduling techniques are used for M2M devices, then individual device control is maintained, but control signaling overhead increases exponentially with the number of M2M devices
Solution Approach 1:
The patent merges multiple individual M2M devices into groups, where a single group control message can address multiple devices simultaneously. This combining approach reduces the total number of control messages needed, as one message can serve the entire group rather than requiring separate messages for each device.
Solution Approach 2:
The patent creates universal group control messages that can serve multiple devices with different requirements. The control messages are designed to be multi-functional, containing both common information applicable to all group members and device-specific information that can be interpreted differently by different devices based on their individual needs.
2Quantity of substance
If group control signaling is implemented to reduce overhead, then control message quantity decreases, but individual device customization and control precision are lost
Solution Approach 1:
The patent segments the control message into distinct components: a common portion that applies to all group members and a device-specific portion that provides individual customization. This segmentation allows the system to maintain both the efficiency of group-wide control and the precision of individual device management within a single unified message structure.
Solution Approach 2:
The patent applies local quality by providing different levels of control information to different devices within the same group. Each device receives the common control information plus its own specific parameters, allowing customization at the local device level while maintaining group-wide coordination through the common portion of the message.
3Ease of operation
If control messages are sent to each M2M device individually, then precise control is achieved, but network resources are consumed and congestion occurs
Solution Approach 1:
The patent combines multiple individual control operations into a single group control message that achieves the same control objectives for multiple devices simultaneously. This merging approach maintains control precision by including device-specific information while dramatically improving network resource efficiency by reducing the total message count.
Solution Approach 2:
The patent performs preliminary grouping of M2M devices based on their control requirements and characteristics before control operations are executed. This preliminary organization allows the system to pre-calculate optimal group configurations that balance control precision with resource efficiency, avoiding the need for individual device processing during actual control operations.
