TCP/IP Stack Data Delivery Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional TCP/IP stacks in mobile networks deliver data sequentially, leading to congestion and poor performance due to varying RF conditions and unequal treatment of premium and non-premium users, resulting in degraded user experience and inefficient data transfer.
Innovation Solution
A modified TCP/IP stack with an application protocol interface (API) that receives delivery optimization information to prioritize data based on RF conditions and user profiles, allowing for optimized data delivery by modifying the transport layer to include additional metadata fields for priority and quality of service, enabling better scheduling and packet management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is delivered sequentially in the order requests are received, then fairness and simplicity are maintained, but network congestion occurs and performance degrades when RF conditions vary or premium users need priority service
Solution Approach 1:
The patent implements dynamic data delivery by modifying the TCP/IP stack to adjust packet transmission based on real-time RF conditions and user priority status. The system transitions from static sequential delivery to dynamic delivery where packets can be retransmitted, prioritized, or delayed based on current network conditions and user profiles, thereby improving productivity without requiring complete system redesign
Solution Approach 2:
The patent changes key parameters of the data delivery process including transmission timing, packet priority levels, and retransmission strategies. By modifying delivery parameters based on RF condition quality metrics and user premium status, the system optimizes data transfer efficiency while maintaining manageable complexity through parameter adjustment rather than structural overhaul
2Reliability
If retransmission of packets is implemented to handle poor RF conditions, then data delivery reliability improves, but network congestion increases and overall system performance degrades
Solution Approach 1:
The patent applies local quality by implementing selective retransmission strategies tailored to specific packets and specific mobile devices based on their individual RF conditions. Rather than uniform retransmission across all traffic, the system adjusts retransmission behavior locally for each device-packet combination, improving reliability for affected devices while minimizing impact on overall network throughput
Solution Approach 2:
The patent performs preliminary assessment of RF conditions and user priority status before initiating data transmission or retransmission. By evaluating channel quality and user profiles in advance, the system can proactively adjust transmission strategies, preventing congestion before it occurs while ensuring reliable delivery when conditions permit
3Ease of operation
If premium users receive priority data delivery, then user experience improvement is achieved, but fairness to non-premium users is compromised and system complexity increases
Solution Approach 1:
The patent implements dynamic service differentiation by continuously monitoring user status and adjusting delivery priority in real-time. Premium users receive enhanced service when needed, while the system dynamically reverts to standard delivery for non-premium users or when network conditions require uniform treatment, thereby improving user experience while maintaining system adaptability and fairness
Solution Approach 2:
The patent modifies delivery parameters such as packet priority tags, queue positioning, and transmission timing based on user premium status. These parameter changes enable service differentiation that improves premium user experience while maintaining backward compatibility and fair treatment for standard users, avoiding the need for completely separate delivery mechanisms
