Message Transmission Delay Management via Time Gap Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile message services cannot determine message transmission delays until a client device receives a push message, and only simple transmission delays can be measured, lacking the ability to actively manage delays caused by network issues.
Innovation Solution
An apparatus and method that calculate a time gap between a message server and a client device using local time information, allowing for the determination of message transmission delays and enabling active management of these delays by adjusting network settings and ping periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional push message transmission is used, then message delivery is simple and fast, but message transmission delay cannot be accurately determined
Solution Approach 1:
The system performs preliminary time synchronization between client and server before message transmission. The server sends a time synchronization message containing its local time, and the client calculates the time gap in advance. This preliminary action enables accurate delay measurement without adding complexity to the actual message transmission process.
Solution Approach 2:
A time gap calculator acts as an intermediary component that mediates between the client's local time and the server's local time. It calculates the time gap based on synchronized time information and uses this gap to determine accurate message transmission delays, separating the measurement function from the transmission function.
2Reliability
If client device calculates delay time using time gap method, then accurate message transmission delay can be determined, but additional time synchronization overhead is introduced
Solution Approach 1:
Time synchronization is performed in advance before message transmission begins. The server sends its local time to the client, and the time gap is calculated beforehand. This preliminary synchronization avoids repeated time exchange during message transmission, minimizing ongoing time overhead while maintaining reliable delay determination.
Solution Approach 2:
The client device autonomously calculates the time gap and uses it to determine message transmission delays without requiring continuous server involvement. Once the time gap is established, the client independently measures delays by comparing server send time with client receive time using the pre-calculated gap, reducing communication overhead.
3Productivity
If network connection history is stored and analyzed, then optimal network selection for message reception can be determined, but storage and processing requirements increase
Solution Approach 1:
The system extracts only the essential elements from network connection history - specifically delay times and network identification information - rather than storing complete connection records. This extraction approach enables effective network selection for message reception while minimizing storage requirements and processing overhead.
Solution Approach 2:
The system maintains different levels of history information for different networks based on their importance and usage patterns. Frequently used networks with better performance receive more detailed tracking, while less important networks receive minimal monitoring. This localized quality approach optimizes storage and processing resources according to actual needs.
