Core Network Trigger Message Storage Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication networks waste storage resources due to the overtime storage of trigger messages for terminals, which are not promptly removed before their validity timers expire.
Innovation Solution
A method and system where a control network element in the core network stores and removes trigger messages before their validity timer expires, using timers such as the mobile reachable timer and implicit detach timer to determine when to remove the messages, and transmits a trigger response message to notify servers of failed transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network retains trigger messages after the terminal receives them, then the terminal can respond to server triggers, but storage resources of the network are wasted
Solution Approach 1:
The network entity receives an acknowledgement message from the terminal indicating successful receipt of the trigger message, and uses this feedback to determine when to remove the stored trigger message, thereby eliminating unnecessary storage while maintaining reliability
Solution Approach 2:
The trigger message is removed from storage before the validity timer expires, preventing waste of storage resources while ensuring the terminal has already received and can act on the message
2Loss of substance
If the network removes trigger messages before validity timer expires, then storage resources are saved, but the terminal may not have time to respond
Solution Approach 1:
The system uses feedback from the terminal's acknowledgement message to determine the optimal removal time, ensuring the message is retained until the terminal has confirmed receipt, thus maintaining reliability while optimizing storage usage
3Reliability
If the network stores trigger messages until validity timer expires, then message delivery is ensured, but storage resources are unnecessarily consumed
Solution Approach 1:
The trigger message is removed from storage before the validity timer expires, as long as the terminal has acknowledged receipt, thereby preventing unnecessary consumption of storage resources while ensuring message delivery through prior acknowledgement

AI summary
A method and system for processing trigger message of a terminal, wherein, the method includes: after receiving trigger message which is transmitted from a machine type communication server to the terminal, a control network element in a core network storing the trigger message of the terminal, and removing the trigger message of the terminal before a validity timer for the trigger message of the terminal expires. The control network element in the present scheme removes the stored trigger message in time before the validity timer for the trigger message of the terminal expires, thus saving the storage resources of the network.
