Zero-Power Terminal Data Reporting Coordination for Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication networks, the challenge of ensuring normal data reception from a large number of zero-power consumption terminals accessing the network simultaneously leads to network congestion or paralysis.
Innovation Solution
A communication method involving terminal devices receiving a trigger signal and reporting data at a first time point related to a waiting duration, with core and access network devices coordinating the transmission of trigger signals and data reception to manage the timing of data reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If zero-power consumption terminals directly access base stations to report data, then terminal access simplicity is improved, but network congestion and data reception reliability deteriorate when many terminals report simultaneously
Solution Approach 1:
The network device performs preliminary actions by sending trigger signals in advance to terminal devices, instructing them to report data at predetermined time points. This preliminary coordination prevents simultaneous data reporting that would cause network congestion, while maintaining the simplicity of direct terminal access.
Solution Approach 2:
The system implements periodic action by establishing regular reporting cycles where terminal devices report data at predetermined time points coordinated by trigger signals. This periodic structure distributes data transmission over time, preventing congestion while preserving direct access simplicity.
2Speed
If many zero-power consumption terminals report data simultaneously, then terminal responsiveness is improved, but network load and data transmission reliability deteriorate
Solution Approach 1:
The network device sends trigger signals in advance to coordinate data reporting timing. This preliminary action allows terminals to maintain fast responsiveness by having predetermined reporting schedules, while the coordination prevents simultaneous transmission that would overload the network and compromise reliability.
Solution Approach 2:
The system dynamically adjusts reporting timing based on network conditions and terminal requirements. The predetermined time points are flexible enough to maintain terminal responsiveness while being coordinated to avoid network congestion, balancing speed and reliability dynamically.
3Reliability
If trigger signals are sent to coordinate data reporting timing, then network data reception reliability is improved, but system complexity and signal management overhead increase
Solution Approach 1:
The network device acts as an intermediary that sends trigger signals to coordinate data reporting. This intermediary approach improves reliability by centralizing timing coordination, while the trigger signal mechanism remains relatively simple compared to more complex distributed coordination systems.
Solution Approach 2:
The system uses feedback mechanisms where the network device monitors terminal reporting and adjusts trigger signals accordingly. This feedback loop improves data reception reliability while keeping the complexity manageable through automated adjustments rather than manual configuration.
