Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network infrastructure is inadequate to meet the unique requirements of Machine to Machine (M2M) services, which differ significantly from Human to Human services in terms of terminal identification, mobility management, data transmission modes, and application features, leading to suboptimal network performance and load management.
Innovation Solution
A dedicated M2M core network is implemented, which identifies M2M equipment through specific identity indication information and selects the corresponding M2M core network for access, allowing the existing network to support M2M services without enhancements or expansions, while maintaining service for Human to Human equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the existing GPRS or EPS network is used for M2M services, then the network infrastructure can be reused without additional deployment, but the network performance and load management become suboptimal due to the significant differences between M2M and H2H service requirements
Solution Approach 1:
The patent segments the core network into separate H2H network elements and M2M network elements. The H2M network handles traditional human-to-human services while the M2M network is specifically designed for machine-to-machine services with appropriate identification, mobility management, and data transmission optimizations. This segmentation allows each network to be optimized for its specific service type without compromising the other.
Solution Approach 2:
The patent applies local quality by creating specialized M2M network elements with specific functionalities tailored to M2M requirements. The M2M network uses different identification mechanisms, mobility management procedures, and data transmission modes that are locally optimized for machine communication patterns, while the H2H network maintains its existing optimizations for human users.
2Reliability
If the existing network is optimized for H2H services, then the network management and communication quality are optimized for human users, but the network cannot effectively meet the unique requirements of M2M services
Solution Approach 1:
The patent divides the network into distinct H2H and M2M domains with separate network elements. The M2M network elements are specifically designed to handle machine identification, mobility management, and data transmission, providing optimized management quality for M2M services while the H2H network continues to serve human users with its existing optimizations.
Solution Approach 2:
The patent introduces an M2M identification mechanism that acts as an intermediary between the terminal and the network core. This intermediary enables the network to recognize and route M2M traffic appropriately, facilitating service compatibility without requiring changes to the existing H2H network operations.
3Reliability
If a dedicated M2M core network is implemented, then the network can effectively meet M2M service requirements with optimized performance, but the network complexity increases compared to using the existing H2H network
Solution Approach 1:
While segmentation does increase architectural complexity by creating separate M2M and H2H network elements, it enables optimized performance for M2M services. The patent manages this complexity through standardized interfaces and procedures that allow the segmented networks to operate independently yet cohesively within the overall network infrastructure.
Solution Approach 2:
The patent designs the M2M network elements to handle multiple M2M service types and requirements through universal mechanisms. The M2M identification, mobility management, and data transmission protocols are designed to be multi-functional, accommodating various M2M applications while maintaining a unified network architecture that doesn't require separate optimizations for each service type.
4Quantity of substance
If the existing network handles both H2H and M2M traffic, then network resources are efficiently utilized, but the unique identification, mobility management, and data transmission requirements of M2M equipment cannot be properly addressed
Solution Approach 1:
The patent introduces an M2M identification mechanism as an intermediary layer between the terminal and network core. This intermediary enables precise identification of M2M equipment by providing dedicated identification procedures and data structures that accurately distinguish M2M terminals from H2H terminals, ensuring measurement precision in equipment identification while maintaining efficient resource utilization through shared network infrastructure.
Solution Approach 2:
The patent applies local quality by implementing M2M-specific identification, mobility management, and data transmission mechanisms within the M2M network elements. These locally optimized procedures ensure accurate identification and proper handling of M2M equipment while the overall network continues to efficiently utilize resources by maintaining separate but parallel H2H network operations.
