Sleep Mode Proxy Response via Sub Controller Bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing proxy response systems face reliability and cost issues due to frequent network route changes and the need for multiple proxy response devices when handling multiple information processing apparatuses in sleep mode, leading to potential communication troubles and high costs.
Innovation Solution
An information processing apparatus with a main controller circuit for normal mode and a sub controller circuit for sleep mode, including separate communication interfaces, allows the sub controller to receive and forward requests and responses between networks, enabling reliable and cost-effective proxy responses without analyzing packets, and a proxy response device unconnected to the primary network handles requests and responses for multiple apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a proxy response device is connected to the same network as information processing apparatuses, then it can respond to requests, but network route changes cause communication troubles and reliability issues
Solution Approach 1:
The patent introduces a bridge device as an intermediary between the proxy response device and the first network. The bridge device translates and forwards packets between different network interfaces, allowing the proxy response device to communicate with information processing apparatuses without being directly connected to the first network. This mediator approach isolates the proxy response device from network route changes while maintaining communication functionality.
2Adaptability or versatility
If multiple proxy response devices are deployed to handle multiple information processing apparatuses, then response coverage is improved, but system cost increases
Solution Approach 1:
The patent makes the proxy response device universal by enabling it to handle requests from multiple information processing apparatuses through the bridge device. Instead of dedicating one proxy response device per information processing apparatus, a single proxy response device can serve multiple apparatuses by receiving their requests through the bridge and sending responses back through the same bridge. This multi-functional approach improves adaptability while reducing the quantity of devices needed.
3Productivity
If the main controller circuit operates continuously, then full functionality is available, but energy consumption increases
Solution Approach 1:
The patent segments the controller into two parts: a main controller circuit and a sub controller circuit. The main controller circuit handles full functionality when needed, while the sub controller circuit maintains basic operational capabilities at lower power consumption. This segmentation allows the system to switch between different operational modes, enabling full productivity when necessary while reducing energy consumption during normal operation.
Solution Approach 2:
The patent implements dynamic operation modes where the system can switch between a normal mode (with full functionality) and a sleep mode (with reduced functionality). The sub controller circuit enables basic operations in sleep mode, and the system can transition to the main controller circuit when full functionality is required. This dynamic approach balances productivity and energy consumption based on actual system needs.

AI summary
An information processing apparatus is selectively executable a normal mode or a sleep mode, the information processing apparatus including: a main controller circuit that operates in the normal mode; a sub controller circuit that operates in the sleep mode; a first communication interface capable of communicating with an external apparatus connected to a first network; and a second communication interface capable of communicating with a proxy response device, the proxy response device being unconnected to the first network. In the sleep mode, the sub controller circuit receives a request from the external apparatus via the first communication interface, sends the request to the proxy response device via the second communication interface, receives a response to the request from the proxy response device via the second communication interface, and sends the response to the external apparatus via the first communication interface.
