M2M Connectivity via CSE Point of Access Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine-to-machine (M2M) communication, devices without a Common Service Entity (CSE) face challenges in establishing effective connectivity due to limited reachability information, particularly the lack of 'pointOfAccess' for remotely hosted Application Entities, which impedes communication across different networks.
Innovation Solution
The solution involves creating a 'pointOfAccess' resource attribute, such as an IP address or MAC address, at the CSE hosting the registration for remotely hosted Application Entities, enabling M2M communication by facilitating the allocation of resources and establishing connectivity between nodes through the Mca reference point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If devices without a Common Service Entity (CSE) are used in M2M communication, then device complexity is reduced, but connectivity and reachability information are limited
Solution Approach 1:
The CSE acts as an intermediary that hosts registrations for remotely hosted Application Entities. The CSE stores pointOfAccess resource attributes that enable other nodes to establish connectivity to devices that do not themselves host CSEs, thus mediating the connectivity gap between simple devices and the network.
Solution Approach 2:
The solution introduces a new dimension of connectivity by creating a pointOfAccess resource attribute at the CSE level that is separate from the device's own addressing. This allows remote devices to be reached through the CSE's registered address information, adding a network-level access dimension to device communication.
2Adaptability or versatility
If remotely hosted Application Entities are used, then adaptability across different networks is improved, but reachability information is insufficient
Solution Approach 1:
The CSE performs preliminary action by hosting the registration and storing the pointOfAccess resource attribute before any communication occurs. This pre-established address information ensures that when remote devices need to communicate, the reachability information is already available at the CSE, eliminating the need for devices to have their own CSE functionality.
3Reliability
If pointOfAccess resource attribute is created at CSE, then connectivity between M2M nodes is enhanced, but device complexity increases
Solution Approach 1:
The complex functionality of hosting registrations and managing pointOfAccess information is extracted from individual devices and placed at the CSE level. This allows devices to remain simple while the system as a whole gains enhanced connectivity capabilities through the centralized CSE infrastructure.

AI summary
In a machine to machine (M2M) communication system, a common service entity hosts a registration for a remotely hosted application entity, stores a point of access address corresponding to the remotely hosted application entity, and thereby facilitates M2M communication between the remotely hosted application entity and another M2M node. The communication may be performed over the Mca interface.
