Downlink Packet Transmission via Paging Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transmitting downlink data packets in 5G communication systems experience significant transmission delays, leading to inefficiencies in resource utilization and increased power consumption.
Innovation Solution
A method where a terminal receives a paging message indicating data transmission, allowing it to directly receive downlink data packets without establishing an RRC connection, thereby reducing delay and power consumption, and optimizing network signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal establishes an RRC connection before receiving downlink data packets, then the connection reliability is improved, but the transmission delay increases
Solution Approach 1:
The network side device performs preliminary actions by transmitting the paging message with data transmission indication before the terminal completes RRC connection establishment. This allows the terminal to prepare for direct data reception without waiting for full connection setup, thereby reducing transmission delay while maintaining connection reliability through the indication mechanism.
Solution Approach 2:
The invention extracts the essential data transmission function from the complete RRC connection establishment procedure. By separating the data transmission indication from the full connection setup process, the system enables direct data packet transmission without requiring the terminal to complete all RRC connection steps, thus reducing delay while maintaining necessary reliability.
2Stability of the object's composition
If the terminal performs state transition to establish RRC connection, then the connection stability is improved, but the power consumption increases
Solution Approach 1:
The invention applies partial action by implementing only the necessary state transition for direct data reception rather than completing the full RRC connection establishment. The terminal transitions to a state that enables data reception without performing all unnecessary connection setup procedures, thereby reducing power consumption while maintaining sufficient connection stability for data transmission.
Solution Approach 2:
The system extracts the essential state transition requirement from the complete RRC connection procedure. By identifying and implementing only the minimal state change needed for direct data reception, the invention eliminates excessive power consumption associated with full connection establishment while preserving the necessary connection stability for reliable data transmission.
3Reliability
If the network side device transmits downlink data packets through established RRC connection, then the transmission reliability is improved, but the network signaling overhead increases
Solution Approach 1:
The invention extracts the data transmission function from the complex RRC connection establishment signaling. By using the paging message with data transmission indication as a streamlined alternative, the network side device can transmit downlink data packets with minimal signaling overhead while maintaining transmission reliability through the indication mechanism that ensures proper terminal preparation.
Solution Approach 2:
The system segments the network signaling process into two parts: the paging message with data transmission indication (minimal overhead) and the actual data packet transmission. This segmentation eliminates the need for complete RRC connection establishment signaling while maintaining reliability, as the indication ensures the terminal is properly prepared for direct data reception.
