Message Filtering in Communication Control to Cut Network Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in reducing network traffic volume, particularly when devices transmit messages that do not need to be sent to a server, leading to unnecessary network congestion.
Innovation Solution
A communication system with a communication control apparatus that acquires device messages, determines whether they satisfy non-transmission conditions based on IP address and class information, and discards messages that do not need to be transmitted to the server, thereby controlling message transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all device messages are transmitted to the server through the network, then the server can process all messages, but the network traffic volume increases causing congestion
Solution Approach 1:
The patent extracts and removes unnecessary messages from the transmission stream by implementing a determination unit that identifies messages satisfying non-transmission conditions and a transmission control unit that prevents their transmission. This extraction of harmful elements (unnecessary messages) reduces network traffic volume while preserving necessary messages for processing.
Solution Approach 2:
The patent applies preliminary action by determining whether a message should be transmitted before actual transmission occurs. The determination unit evaluates non-transmission conditions in advance, and the transmission control unit preemptively prevents transmission of messages that will be discarded, thereby reducing network traffic before congestion can occur.
2Quantity of substance
If a message processor discards messages satisfying predetermined conditions, then network traffic is reduced, but the device complexity increases due to additional processing components
Solution Approach 1:
The patent segments the message processing function into distinct components: a determination unit that evaluates non-transmission conditions, a transmission control unit that controls message transmission based on determination results, and a receiver that receives messages. This segmentation allows each component to perform its specific function efficiently, reducing overall system complexity while achieving traffic reduction.
Solution Approach 2:
The transmission control unit acts as an intermediary between the receiver and the network transmission interface. It receives messages from the receiver, determines whether they should be transmitted based on non-transmission conditions, and controls the actual transmission. This intermediary function simplifies the overall architecture by centralizing the decision-making logic.
3Loss of energy
If the communication control apparatus determines and discards non-transmission messages, then network costs are reduced, but the processing time for message evaluation increases
Solution Approach 1:
The patent applies partial action by evaluating only the necessary conditions for non-transmission determination rather than analyzing all possible message attributes. The determination unit checks specific non-transmission conditions (such as message type, destination, or content criteria) and only performs full evaluation when necessary, thereby reducing evaluation time while still achieving effective traffic reduction.

AI summary
A communication system includes a cloud server, and a communication control apparatus to be connected to the cloud server and a device through a wide area network and a local area network. The communication control apparatus transmits a device message generated by the device to the cloud server. The communication control apparatus includes a message acquirer that acquires the device message from the device, a determiner that determines whether the device message satisfies a non-transmission condition, and a transmission controller that controls transmission of the device message to the cloud server. The transmission controller discards the device message to avoid transmission of the device message to the cloud server when the device message is determined to satisfy the non-transmission condition.
