M2M Application Server Gateway for RAN Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for Machine-to-Machine (M2M) communications through Radio Access Networks (RAN) are inadequate, particularly for mobile M2M applications, as they do not effectively manage the interactions and identifications required for efficient communication between M2M service devices and application servers.
Innovation Solution
A machine-to-machine application server and service device configuration that utilizes distinct identifiers for service and transport layers, allowing direct or indirect communication through the RAN, with M2M service devices and transport devices using separate or integrated identifiers to access the application server, enabling flexible communication paths and authentication mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If service devices connect directly to the Radio Access Network, then communication simplicity is improved, but network capacity is exceeded and reliability deteriorates
Solution Approach 1:
The patent introduces a gateway as an intermediary component between service devices and the Radio Access Network. The gateway receives service information from multiple service devices, aggregates it, and forwards it to the RAN, thereby reducing the number of direct connections needed while maintaining communication simplicity for individual devices.
Solution Approach 2:
The patent segments the network architecture into distinct functional components: service devices, gateway, and Radio Access Network. This segmentation allows the gateway to handle aggregation and management functions separately from the RAN, improving overall network reliability and capacity management.
2Reliability
If a nested architecture with transport devices is implemented, then network capacity is preserved, but device complexity increases
Solution Approach 1:
The gateway is designed as a universal component that can handle multiple functions: receiving service information from various service devices, aggregating data, managing transport to the RAN, and supporting both direct and indirect access modes. This multi-functionality reduces the need for multiple specialized components, simplifying the overall architecture.
3Reliability
If distinct identifiers are used for service and transport layers, then authentication reliability is improved, but information processing complexity increases
Solution Approach 1:
The patent segments the identification system into two distinct layers: service information identifiers and transport information identifiers. This segmentation allows each identifier type to serve its specific function independently, improving authentication reliability by ensuring that service-level and transport-level security requirements are met separately without interference.
