Message Tagging for SMS-Only Mobile Network Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices connected to non-terrestrial PLMNs like satellite networks are limited to SMS communications, leading to undelivered messages and communication disruptions due to network incompatibilities, as other communication methods like RCS are not recognized by the receiving device.
Innovation Solution
A message modification attribute value is generated by network nodes to indicate that SMS or MMS communication should be used for a specified duration, ensuring compatibility and minimizing disruption by modifying the message to reflect the recipient's communication capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system attempts to send instant messages or data-based communications to a mobile device, then communication speed and bandwidth utilization improve, but message delivery fails when the device is only accessible via SMS
Solution Approach 1:
The system performs preliminary detection of the mobile device's communication accessibility status before initiating message transmission. By checking whether the device is reachable via SMS or data-based communication in advance, the system selects the appropriate communication channel, ensuring both communication speed and message delivery success without attempting failed transmissions
Solution Approach 2:
The system uses feedback from SMS message delivery status to determine the appropriate communication channel. When an SMS message is successfully delivered to a mobile device, the system receives confirmation feedback and switches to data-based communication methods for subsequent messages, thereby achieving high-speed communication while maintaining delivery reliability
2Reliability
If the system automatically detects communication channel eligibility, then message delivery reliability improves, but system complexity increases due to additional detection and modification mechanisms
Solution Approach 1:
The system enables mobile devices to self-report their communication channel accessibility status. Devices automatically indicate whether they are reachable via SMS or data-based communication, eliminating the need for complex centralized detection mechanisms while maintaining high message delivery reliability through device-initiated status reporting
Solution Approach 2:
The system introduces a message modification attribute as an intermediary element that carries communication channel information. This attribute acts as a mediator between the communication channel detection mechanism and the message transmission process, simplifying the overall system architecture by encoding channel eligibility information in a standardized format that can be processed without complex decision-making logic

AI summary
The invention relates to using a message modification attribute value to indicate restrictions on lines of communication that may be used for a particular device. In some aspects, a network node of a telecommunications network receives a request to deliver a SMS message from a first mobile device to a second mobile device. The network node determines that the first mobile device is eligible to receive SMS messages but not instant messages. Therefore, the network node generates a message modification attribute value indicating the communication channel via which messages are to be delivered to the first mobile device. The network node sends the SMS message to the second mobile device modified by the message modification attribute value. The second mobile device receives the message and, based on the message modification attribute value, acknowledges to use SMS communication with the first mobile device for a first duration of time.
