M2M Coordinator Association Request Message for Sensor and IP Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional association process of terminal devices with both sensor networks and IP networks involves multiple signaling interworking, leading to wastage of network resources and non-compliance with low power-consumption principles.
Innovation Solution
A method that simplifies the association process by using an Association Request message with an IP identifier to determine whether a terminal device requests association with an IP network, allowing for streamlined processing through an M2M Coordinator or Coordinator, which sends an IP network Association Request message to an Edge Router, and returns the results to the terminal device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the conventional association process is used for terminal devices to associate with both sensor networks and IP networks, then the association can be completed, but multiple signaling interworking is required which wastes network resources and increases power consumption
Solution Approach 1:
The patent combines the sensor network association process and IP network association process into a single integrated association request message. The terminal device sends one Association Request message that includes both sensor network association information and IP network association information (via the IP identifier), allowing the coordinator to handle both associations simultaneously rather than requiring separate signaling sequences for each network type.
Solution Approach 2:
The Association Request message is designed to serve multiple functions: it handles sensor network association, indicates IP network association requirements through the IP identifier, and enables the coordinator to process both types of associations through a unified interface. This multi-functional approach eliminates the need for separate signaling paths for different network types.
2Quantity of substance
If the conventional association process is used for terminal devices to associate with both sensor networks and IP networks, then the association can be completed, but network resources are wasted due to multiple signaling interworking
Solution Approach 1:
The patent merges multiple association signaling sequences into a single integrated process. By combining sensor network association and IP network association into one message exchange, the total quantity of signaling messages transmitted over the network is reduced, thereby conserving network resources while maintaining complete association functionality.
Solution Approach 2:
The association request is segmented into distinct components within a single message structure: sensor network association information and IP network association information (indicated by the IP identifier). This segmentation allows the coordinator to process different association types independently while handling them through a unified signaling path, reducing overall network resource consumption.
3Productivity
If separate association processes are used for sensor networks and IP networks, then each association can be processed independently, but the overall association time is increased due to multiple signaling interworking
Solution Approach 1:
The terminal device prepares both sensor network association information and IP network association information (via the IP identifier) in advance within a single Association Request message before transmission. This preliminary preparation eliminates the need for sequential message exchanges and allows the coordinator to process both associations simultaneously, significantly reducing the total association time.
Solution Approach 2:
By combining both association processes into a single message exchange event, the patent eliminates the time required for multiple separate signaling sequences. The coordinator receives one integrated request and processes both sensor network and IP network associations in parallel or sequential order within the same transaction, reducing overall association time compared to separate independent processes.

AI summary
Embodiments of the present invention provide a method, network element device, and network system for associating a terminal device with a network. The method for associating a terminal device with a network includes: receiving an Association Request message sent by a terminal device, where the Association Request message includes information of a request for associating the terminal device with a sensor network and an IP identifier; processing, according to the Association Request message, the request for associating the terminal device with a sensor network; when it is determined, according to the IP identifier, that the terminal device requests association with an IP network, sending an IP network Association Request message to an Edge Router; receiving a result of processing, by the Edge Router, the request for associating the terminal device with the IP network; sending an Association Respond message to the terminal device.
