Smart Meter Pairing Through Gateway Mediation Across Shared Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of pairing smart meters with the correct information system after subscription is tedious and resource-intensive, especially in systems where multiple information systems share the same network infrastructure.
Innovation Solution
A multi-service gateway facilitates efficient and secure pairing of smart meters with their relevant information systems by using symmetric keys and secure protocols to relay pairing requests and acknowledgments, ensuring only authorized systems can decrypt meter type and identifier information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If smart meters are paired with information systems manually after subscription, then pairing accuracy can be maintained, but deployment time and resource consumption increase significantly
Solution Approach 1:
The smart meter autonomously performs pairing operations by transmitting its identifier and type information to the multi-service gateway, which automatically routes it to the correct information system. This self-service mechanism eliminates manual pairing operations while maintaining pairing accuracy through automated identification and routing processes.
Solution Approach 2:
The smart meter is pre-configured with its identifier and type information before deployment. When the meter is activated, it immediately initiates the pairing process by sending this pre-prepared information to the gateway, enabling automatic routing without requiring manual intervention during deployment.
2Loss of energy
If multiple information systems share the same network infrastructure, then deployment costs are reduced, but pairing complexity increases due to multiple candidate systems
Solution Approach 1:
The multi-service gateway serves as an intermediary between smart meters and multiple information systems. It receives pairing requests from meters, extracts identification information, and automatically routes each meter to the appropriate information system. This intermediary simplifies the pairing process despite the presence of multiple candidate systems by providing a centralized routing mechanism.
Solution Approach 2:
The multi-service gateway performs multiple functions: receiving pairing requests from various smart meter types, decrypting and analyzing meter identifiers, determining the correct information system based on meter type, and routing communications accordingly. This universal gateway handles diverse meter types and routing decisions through a single platform.
3Productivity
If smart meter identifier information is transmitted in plain text, then pairing process speed increases, but security is compromised as unauthorized systems can access meter information
Solution Approach 1:
The multi-service gateway acts as a secure intermediary that receives encrypted pairing requests from smart meters, decrypts them using appropriate keys, processes the identification information, and routes meters to information systems. This intermediary enables secure encrypted transmission while maintaining pairing efficiency through automated decryption and processing.
Solution Approach 2:
The gateway extracts the necessary identification and type information from the encrypted pairing request, processes this extracted data for routing decisions, and then communicates only with the authorized information system. This extraction process ensures that sensitive meter information is handled securely and only shared with authorized systems.

AI summary
To pair an orphaned smart meter (201b) with a relevant information system (110b) designed to remotely manage smart meters in an automated management system comprising multiple candidate information systems, the orphaned smart meter (201b) transmits a pairing request to a multi-service gateway (200). This request includes cleartext information indicating the smart meter type. The multi-service gateway (200) locates, among the candidate information systems, those (110b, 110d) that remotely manage smart meters of the same type as that specified in the pairing request and relays the pairing request accordingly. The relevant information system then transmits a positive acknowledgment in response, including cleartext information for the multi-service gateway (200) and encrypted information for the orphaned smart meter (201b).
