MC Data Server Short Data Service Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mission critical data communication systems face challenges in effectively managing short data services, particularly in on-network and off-network scenarios, where efficient communication and notification mechanisms for SDS are lacking, impacting the reliability and scalability of one-to-one and group communications.
Innovation Solution
A method and system for managing short data services in mission critical data communication systems, involving a processor, memory, and communicator in the MC Data server and UE, which receive and transmit request and disposition messages, enabling efficient SDS communication through signaling and media planes, and supporting unidirectional and bidirectional communications, including multicast capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized support through MC Data server is implemented, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The MC Data server acts as an intermediary component that mediates between MC Data UEs for on-network communications and between UEs for off-network communications. This intermediary approach enables reliable communication management while maintaining architectural flexibility, resolving the contradiction between reliability improvement and system complexity.
2Productivity
If SDS management functionality is added to MC Data server, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The MC Data server is designed with multi-functionality, handling both on-network SDS management and off-network SDS management through a unified architecture. This universal approach improves communication efficiency across different scenarios without proportionally increasing server complexity, as the same core functionality serves multiple purposes.
3Adaptability or versatility
If off-network communication mode is implemented, then system scalability is improved, but communication reliability may deteriorate
Solution Approach 1:
The system dynamically adapts its operation mode based on network conditions and communication requirements. MC Data UEs can switch between on-network and off-network modes as needed, allowing the system to scale flexibly while maintaining reliability through dynamic mode selection rather than fixed architecture.
