Mobile Transport Protocol Bandwidth Latency Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission protocols, such as TCP, are inefficient in low-bandwidth networks like mobile telephony networks, leading to issues with data latency, disconnection handling, and bandwidth utilization, particularly when providing real-time data services.
Innovation Solution
The Mobile Transport Protocol (MTP) is introduced, which adjusts the interval between data packet transmissions to optimize bandwidth usage and ensure timely data delivery by using a heartbeat mechanism to manage connection latency and adjust transmission rates based on network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If data transmission is stopped when data is not required, then bandwidth utilization is improved, but network condition indication capability deteriorates
Solution Approach 1:
The patent implements periodic transmission of control packets (such as keep-alive packets or timing packets) between stations to maintain network condition indication capability even when data transmission is reduced or stopped. These periodic packets allow stations to detect network status, measure round-trip times, and identify connection states without requiring continuous data flow, thus resolving the contradiction between saving bandwidth and maintaining network awareness.
2Loss of time
If transmission interval is reduced to ensure timely delivery, then data timeliness is improved, but bandwidth consumption increases
Solution Approach 1:
The patent dynamically adjusts the transmission interval between data packets based on network conditions, data priority, and timing requirements. For real-time data with strict timing constraints, shorter intervals are used to minimize latency. For non-critical data or when network conditions are poor, intervals are extended to reduce bandwidth consumption. This dynamic adaptation allows the system to optimize the trade-off between timeliness and bandwidth usage in different operational contexts.
Solution Approach 2:
The patent changes transmission parameters such as packet size, transmission interval, and packet type (data vs. control packets) based on network conditions and data requirements. By varying these parameters, the system can achieve timely delivery for critical data while minimizing overall bandwidth consumption across the network.
3Reliability
If existing protocols like TCP are used, then reliable transmission is achieved, but efficiency in low-bandwidth networks deteriorates
Solution Approach 1:
The patent implements a specialized transmission protocol optimized for low-bandwidth networks that differs from standard TCP in specific aspects while maintaining reliability. The protocol uses smaller, more frequent control packets, simplified acknowledgment mechanisms, and timing-based flow control tailored for constrained networks. This local optimization allows reliable transmission without the overhead and complexity of full TCP, thereby improving transmission efficiency in low-bandwidth environments while preserving necessary reliability guarantees.
Data Source
AI summary
A data transmission method, wherein a first station transmits packets of data to a second station and the interval between data packet transmissions from said first station to said second station does not exceed a specified time interval, and said second station transmits packets of data to said first station and the interval between data packet transmissions from said second station to said first station does not exceed said specified time interval. Said first station identifies a preferred maximum interval of time between data packet transmissions and transmits a data packet to said second station containing a request that the interval between data packet transmissions does not exceed said preferred maximum interval. Said second station transmits a data packet to said first station containing a confirmation of said request, and said first station and said second station adjust said specified interval to substantially satisfy said preferred maximum interval.
