Short Message Server Triggering MTC Terminals via Identifier Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for triggering MTC terminals using SMS in communication networks face challenges such as insufficient MSISDN resources and inability to operate with other terminal identities, leading to network overload and inefficient data transmission.
Innovation Solution
A short message server system that includes an interface module to receive and deliver trigger requests, a terminal identifier mapping module to convert non-MSISDN identifiers to IMSI, and a determination module to identify and manage duplicate messages, ensuring successful message transmission and load control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MSISDN is used as terminal identifier for SMS triggering, then SMS delivery is possible, but MSISDN resources are insufficient and network overload occurs
Solution Approach 1:
The patent introduces a mapping mechanism that acts as an intermediary between the terminal identifier (which can be any type such as device ID, IP address, or URI) and the MSISDN required for SMS delivery. The short message server maintains a mapping table that translates various terminal identifiers to corresponding MSISDNs, allowing SMS to be delivered without directly consuming MSISDN resources for every terminal. This resolves the contradiction by enabling reliable SMS delivery through the mapping intermediary while preserving limited MSISDN resources.
2Adaptability or versatility
If terminal identifier mapping is implemented, then support for various terminal identities is improved, but system complexity increases
Solution Approach 1:
The short message server is designed with multi-functionality to handle various terminal identifier types (device IDs, IP addresses, URIs, etc.) in addition to its core SMS delivery function. The server includes a mapping module that universally accepts different identifier formats and converts them to MSISDNs, making the system adaptable to diverse terminal identities without requiring separate systems for each identifier type. This universal approach improves versatility while keeping the added complexity manageable within a single server architecture.
3Reliability
If duplicate message determination is added, then message transmission reliability is improved, but processing time increases
Solution Approach 1:
The short message server performs preliminary actions by maintaining a record of previously sent messages and their status in advance of new message arrivals. When a new trigger request arrives, the server immediately checks this pre-maintained record to determine if it's a duplicate, rather than performing complex analysis at message processing time. This preliminary preparation of message status information enables fast duplicate detection, improving reliability while minimizing processing time loss.

AI summary
The present application relates to a control function related to a trigger in a communication network for machine-type communication. A method for triggering a terminal comprises the steps of: receiving a trigger request message from a trigger request transmission server which transmits trigger requests from external servers; and transmitting the trigger request message to a terminal using a received short message, wherein transmission parameters of the short message indicates that the received short message is a short message for triggering a machine-type communication (MTC) apparatus.
