Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of unmanned machines transmitting data wirelessly puts a strain on wireless communication networks, as registering these machines requires inefficient use of network resources and consumes valuable resources due to the inefficiency in managing machine-to-machine traffic.
Innovation Solution
A method is introduced where a wireless access node allocates machine-to-machine channels with individual quality of service levels per sector, receives machine-to-machine traffic, determines the quality of service level based on the sector and channel, and transfers the traffic to a machine-to-machine server accordingly, allowing for efficient aggregation and prioritization.

Engineering Contradiction Analysis
1Productivity
If machine-to-machine devices transmit data frequently through the wireless network, then data service availability is improved, but network resource consumption increases due to inefficient registration processes
Solution Approach 1:
The patent implements a one-time registration process where machine-to-machine devices are pre-registered with the wireless network before actual data transmission begins. This preliminary action stores device identifiers and service requirements in advance, eliminating the need for repeated registration handshakes during frequent data exchanges, thereby maintaining high service availability while reducing cumulative network resource consumption
Solution Approach 2:
The patent segments the network communication process into distinct phases: a one-time registration phase that establishes device identities and service parameters, followed by multiple efficient data transmission phases that leverage the pre-established connections. This segmentation allows the system to handle frequent transmissions without repeating the overhead of full registration procedures
2Productivity
If individual quality of service levels are assigned to machine-to-machine channels per sector, then traffic management efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies local quality by assigning different quality of service levels to different machine-to-machine channels within each sector based on specific traffic requirements. Instead of uniform quality levels across the entire network, each channel receives tailored quality parameters (such as priority, bandwidth allocation, or latency tolerance) appropriate to its specific data transmission needs, thereby improving overall traffic management efficiency while keeping the complexity localized to channel configuration rather than system-wide complexity
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting quality of service parameters for different channels and sectors based on network conditions and traffic demands. The system can modify parameters such as channel priority, data rate allocations, or access permissions without fundamentally changing the system architecture, allowing efficient traffic management through parameter optimization rather than structural complexity

AI summary
A wireless access node to manage machine-to-machine data transmissions comprises a processing system, a wireless communication transceiver, and a communication transceiver. The processing system is configured to allocate a plurality of machine-to-machine channels reserved for machine-to-machine communications, and assign individual quality of service levels to individual ones of the machine-to-machine channels per sector. The wireless communication transceiver is configured to receive machine-to-machine traffic on one of the machine-to-machine channels. The processing system is configured to determine a quality of service level for the machine-to-machine traffic based on the sector and the machine-to-machine channel over which the machine-to-machine traffic was received. The communication transceiver is configured to transfer the machine-to-machine traffic for delivery to a machine-to-machine server based on the quality of service level for the machine-to-machine traffic.
