Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems, particularly 4G and 5G, fail to provide the reliability required for periodic data transmissions in factory automation and motion control systems, leading to interruptions that can cause production halts and increased costs due to insufficient communication service availability.
Innovation Solution
A method and system for periodic data transmission in mobile communication networks that involve obtaining receiving window and survival time information for entities, allowing for the transmission of ancillary messages based on adverse responses to ensure reliable data exchange, even during network interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If periodic transmissions are sent continuously in mobile communication systems, then data exchange frequency is improved, but reliability deteriorates due to network interruptions causing production halts
Solution Approach 1:
The system performs preliminary actions by sending a message before the receiving window and using survival time to determine if retransmission is needed. The transmitting entity proactively manages potential failures by tracking whether messages were received within the required time window, allowing it to take corrective action before critical failures occur.
Solution Approach 2:
The system implements feedback mechanisms where the transmitting entity monitors adverse responses (acknowledgments or lack thereof) from the receiving entity. Based on this feedback within the survival time period, the system dynamically adjusts by sending ancillary messages to ensure reliable delivery, creating a closed-loop control system that adapts to network conditions.
2Stability of the object's composition
If periodic transmissions use fixed transmission intervals, then transmission predictability is improved, but adaptability to network conditions deteriorates
Solution Approach 1:
The system combines static periodic transmission intervals with dynamic adaptive behavior. While messages are sent at fixed intervals, the system dynamically adjusts by introducing ancillary messages when adverse responses are detected. This allows the transmission schedule to adapt to network conditions while maintaining the underlying periodic structure for predictability.
Solution Approach 2:
The system uses periodic action by maintaining regular transmission intervals while superimposing conditional ancillary transmissions. The periodic message schedule provides a stable foundation, while the conditional ancillary messages (sent based on survival time expiration) provide adaptive response to network failures, combining regularity with flexibility.
3Reliability
If ancillary messages are sent upon adverse responses, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The system extracts the reliability assurance function into a separate ancillary message mechanism. Instead of complicating the primary periodic transmission protocol, the system isolates the error handling into distinct ancillary messages that are only sent when needed (upon adverse responses), keeping the core transmission simple while adding reliability where necessary.
Solution Approach 2:
The survival time parameter acts as an intermediary that mediates between the periodic transmission schedule and the adverse response handling. It provides a clear threshold for determining when ancillary messages should be sent, simplifying the decision logic by using a time-based criterion rather than complex analysis of network conditions.
4Measurement precision
If survival time and receiving window parameters are tracked, then transmission accuracy is improved, but information processing load increases
Solution Approach 1:
The system applies partial action by tracking timing parameters (survival time and receiving window) only for periodic transmissions that require reliability assurance, rather than all communications. The detailed timing monitoring is applied selectively to critical periodic messages, balancing measurement precision with acceptable processing overhead for non-critical traffic.

AI summary
The present invention provides a method and system of periodic transmission of data between a first entity and a second entity within a mobile communication network. In order to increase transmission quality and take into account application characteristics of the network entities the first entity is able to obtain an adverse response from the second entity and provide an ancillary message to the second entity, where the ancillary message may have different contents depending on transmission circumstances, with the aim to increase the quality of transmission and to ensure the application requirements are met in different situations.
