MTC Trigger Validity Time Processing in SMS Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mobile communication networks are inadequate for efficient machine-to-machine (M2M) communication, lacking optimization for M2M services, and there is a need to effectively set and process validity time in trigger information within the SMS to ensure successful communication without network overload or complexity.
Innovation Solution
A method and system where a machine type communication (MTC) server sends trigger information including validity time (VT) to a network edge entity, which sets a validity period (VP) for the trigger information in a short message service (SMS) and forwards it through a network node within this period, ensuring timely delivery to user equipment and handling failures by deleting expired information and reporting failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the MTC server sends trigger information through SMS with validity time, then the trigger delivery reliability is improved, but the network processing complexity increases
Solution Approach 1:
The network edge entity pre-processes the trigger information by extracting the validity time parameter from the received trigger message before forwarding to network nodes. This preliminary action ensures that all subsequent network operations are aware of the validity constraints, improving delivery reliability while distributing the processing complexity across multiple entities rather than concentrating it in one location.
Solution Approach 2:
The network edge entity acts as an intermediary between the MTC server and the network nodes. It receives the trigger information with validity time from the MTC server, processes and forwards it to network nodes, and receives acknowledgments back. This intermediary role simplifies the overall network complexity by providing a centralized processing point while ensuring reliable delivery through structured message passing.
2Loss of time
If the network nodes store and forward trigger information within validity period, then the trigger information freshness is improved, but the network resource consumption increases
Solution Approach 1:
The network nodes perform periodic checks on the validity period of stored trigger information. Instead of continuously processing all trigger messages, nodes periodically verify whether the current time is within the validity period before forwarding. This periodic action maintains information freshness by ensuring timely delivery while reducing network resource consumption by avoiding continuous processing operations.
Solution Approach 2:
The network nodes apply partial action by only processing and forwarding trigger information that falls within the valid time period. Trigger messages outside their validity period are discarded without further processing. This selective processing ensures that only fresh, relevant information is transmitted, maintaining information freshness while minimizing unnecessary network resource consumption on expired messages.
3Manufacturing precision
If the network edge entity maps validity time to validity period, then the trigger information processing accuracy is improved, but the operation complexity increases
Solution Approach 1:
The network edge entity performs a parameter transformation by mapping the validity time parameter from the trigger information into a validity period parameter suitable for SMS message format. This parameter change ensures processing accuracy by converting the time specification into the appropriate format required by the SMS protocol, while the automated mapping process minimizes operational complexity through systematic transformation rules.
