Network Node M2M Data Transmission Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of M2M devices leads to inefficient network resource management, causing data traffic bursts due to uncontrolled data transmission, which can overwhelm existing data traffic and become a significant problem as more devices are deployed.
Innovation Solution
A method is implemented in network nodes and M2M devices to manage unicast channel data transmission by receiving requests, determining network load, and broadcasting instructions to M2M devices on when to transmit data, ensuring that data is sent only when the network is suitable, thereby controlling both downlink and uplink transmissions.

Engineering Contradiction Analysis
1Productivity
If all M2M devices transmit data whenever they are able to, then data transmission from M2M devices is maximized, but network traffic bursts occur and network resources become overwhelmed
Solution Approach 1:
The network node performs preliminary assessment of network load conditions before allowing M2M data transmission. The node determines whether the network can accommodate additional traffic and sends control messages to M2M devices in advance, instructing them to transmit or defer transmission based on current network capacity, thereby preventing traffic bursts before they occur
Solution Approach 2:
The system implements a feedback mechanism where the network node continuously monitors network load and sends control messages back to M2M devices based on current conditions. M2M devices receive instructions to either transmit collected data or defer transmission, and the node adjusts these instructions dynamically based on ongoing network status, creating a closed-loop control system that balances transmission volume with network stability
2Reliability
If M2M devices are controlled to transmit only when network load is low, then network stability is maintained, but data transmission efficiency decreases
Solution Approach 1:
The control system dynamically adjusts transmission permissions based on real-time network load conditions. The network node continuously evaluates network capacity and sends control messages to M2M devices that reflect current conditions, allowing devices to transmit when network capacity is available and defer when it is not, thereby adapting transmission efficiency to actual network state rather than using fixed control rules
Solution Approach 2:
The system changes the operational parameters of M2M devices based on network conditions. The network node sends control messages that modify the transmission behavior of M2M devices, switching between transmission and deferral states based on network load parameters, thereby optimizing the balance between maintaining stability and achieving efficient data transmission

AI summary
A method executable in a network node, capable of managing transmission of data transmitted over a unicast channel in a communication network from a plurality of M2M devices located in a broadcast service area is provided. Upon receiving a request to transmit collected data over the communication network via a unicast channel from a M2M device located in the first broadcast service area, the network node determines when to allow transmission of the collected data for M2M devices located in the first broadcast service area, on the basis of the network load of the communication network. The result is transmitted to the M2M devices located in the first broadcast service area, instructing at least one of these M2M devices when to transmit collected data over the unicast channel.
