Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems often fail to determine the appropriate Quality of Service (QoS) band for data communication, leading to inefficient data transmission.
Innovation Solution
A communication apparatus that determines whether the transmission destination is an internal or external device within the same LAN, using different methods to select an appropriate QoS band based on this distinction, ensuring optimal data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the guaranteed band is decided based on the kind of application, then the terminal device can perform data communication using a guaranteed band, but an appropriate guaranteed band may not be decided leading to inefficient data transmission
Solution Approach 1:
The patent applies local quality by differentiating the QoS decision-making process based on the transmission scenario. When the destination is an internal device, the system selects a first QoS value optimized for local network conditions, while for external destinations, it selects a second QoS value suited for wide-area transmission. This scenario-specific adaptation resolves the contradiction by making the guaranteed band selection both efficient and contextually appropriate.
Solution Approach 2:
The system dynamically adjusts the QoS value based on real-time determination of whether the destination is internal or external. The deciding unit changes its selection criteria according to the transmission scenario, transitioning between different QoS values. This dynamic adaptation enables the system to maintain high productivity across varying network conditions while preserving versatility.
2Productivity
If a single guaranteed band is used for all applications, then the system is simple to operate, but data communication cannot be optimized for different transmission scenarios
Solution Approach 1:
The patent segments the QoS selection process into distinct pathways based on transmission destination type. The determining unit divides the decision space into internal device scenarios and external device scenarios, with each segment having its own optimized QoS selection logic. This segmentation allows the system to achieve sophisticated optimization without overwhelming complexity, as each segment can be independently managed.
Solution Approach 2:
The determining unit acts as an intermediary between the application layer and the QoS selection mechanism. It receives information about the transmission destination and translates this into appropriate QoS value selection. This intermediary layer simplifies the overall system architecture by centralizing the decision logic, making the system easier to operate while still enabling scenario-specific optimization.
3Productivity
If different QoS values are selected for internal and external devices, then data communication is optimized for each scenario, but the system requires complex determination logic
Solution Approach 1:
The determining unit employs self-service mechanisms to automatically ascertain whether the destination is an internal or external device. By utilizing readily available network information and simple determination criteria, the system avoids complex external verification processes. This self-determination approach maintains high communication efficiency while minimizing the operational difficulty of the determination process.

AI summary
A communication apparatus (10) includes: a first determining unit (50) that determines whether specific identification information designated as a transmission destination of object data to be transmitted is identification information assigned to an internal device (60) within a LAN (2) including the communication apparatus (10); a deciding unit (54) that decides a specific guaranteed band to be used for transmission of the object data, from a plurality of guaranteed bands, based on the determination result; and a first communication unit (56) that transmits the object data by performing IP communication using the specific identification information and the specific guaranteed band. If the specific identification information is the identification information assigned to the internal device (60), the deciding unit (54) decides the specific guaranteed band using a first deciding method. If the specific identification information is not the identification information assigned to the internal device (60), the deciding unit decides the specific guaranteed band using a second deciding method.
