Consolidating MCData Disposition Notifications via Timer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Mission Critical Data (MCData) communication systems face inefficiencies in managing Short Data Service (SDS) disposition notifications, leading to increased resource consumption and retransmissions due to separate 'delivered' and 'read' notifications.
Innovation Solution
A method and system that consolidate 'delivered' and 'read' notifications into a single 'delivered and read' notification by initiating a timer at the receiving MCData UE when the SDS message disposition request is set as 'Delivery and Read', and transmitting this consolidated notification upon message read before timer expiry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate 'delivered' and 'read' notifications are transmitted for SDS messages, then the transmitting UE can track message status accurately, but the number of retransmissions and resource consumption increases
Solution Approach 1:
The patent combines separate 'delivered' and 'read' notifications into a single consolidated disposition notification. The receiving UE now sends one unified notification that indicates both delivery status and read status, eliminating the need for separate notification messages and reducing overall resource consumption while maintaining complete message status tracking.
Solution Approach 2:
The patent introduces dynamic behavior where the receiving UE determines notification timing based on whether the message has been read. If read before timer expiry, a consolidated notification is sent immediately; if not read, only a delivered notification is sent. This dynamic approach optimizes resource usage based on actual message consumption patterns.
2Loss of information
If multiple disposition notifications are transmitted for each SDS message, then complete delivery and read status information is provided, but the number of retransmissions increases
Solution Approach 1:
The patent merges multiple disposition notifications (delivered notification and read notification) into a single consolidated disposition notification. This consolidated notification contains both delivery status and read status information, providing complete disposition status information while reducing the number of retransmissions from two separate notifications to one unified notification.
3Reliability
If separate delivered and read notifications are used, then comprehensive message disposition tracking is achieved, but system complexity increases
Solution Approach 1:
The patent simplifies notification management by merging the logic for handling separate delivered and read notifications into a single consolidated notification mechanism. The receiving UE now manages one type of disposition notification that encapsulates both delivery and read status, reducing the complexity of notification management while maintaining comprehensive message disposition tracking capabilities.
Data Source
AI summary
The embodiments herein provide a method for managing short data service (SDS) disposition notifications in a Mission Critical Data (MCData) communication system. The method includes identifying, by a receiving MCData User Equipment (UE), SDS disposition request type Information Element (IE) in a SDS message received from a transmitting MCData UE. Further, the method includes initiating, by the receiving MCData UE, a timer when the disposition request type Information Element (IE) is set as Delivery and Read. Furthermore, the method includes transmitting, by the receiving MCData UE, a consolidated disposition notification to the transmitting MCData UE by stopping the timer when the SDS message is read before expiry of the timer.
