Control Server Grouping for Dynamic IP Peripheral Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IP-based wireless communication systems, users face difficulties in controlling peripheral nodes, especially when the correspondent node's IP address changes, and when the node lacks a display device, making it hard to manage connections and control devices effectively.
Innovation Solution
An apparatus and method for controlling peripheral nodes in an IP-based wireless communication system using a control server that registers devices in a group list based on user identification information, checks IP addresses, and sends control commands, enabling easy management and control of devices through a control node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile node uses a dynamic IP address allocated through DHCP, then the node can be automatically configured and connected to the network, but the IP address changes cause difficulty in maintaining stable communication and control
Solution Approach 1:
The patent introduces a control server as an intermediary that maintains a mapping between device identifiers (such as MAC addresses or user IDs) and dynamic IP addresses. When the IP address changes, the control server updates the mapping accordingly, allowing the mobile node to maintain stable communication through the intermediary rather than relying on the static IP address itself.
2Device complexity
If a correspondent node has no display device, then the node can be simpler and more functional, but the user cannot check the correspondent's IP address and thus cannot control the node easily
Solution Approach 1:
The control server acts as an intermediary that handles the complexity of IP address management and device control. The user interacts with the control server through a control interface, which retrieves device information and IP addresses from the server. This allows users to control devices without the devices themselves needing display devices, as the control server provides the necessary information and control mechanisms.
Solution Approach 2:
The control server maintains a copy of device information including IP addresses and device identifiers. Instead of requiring the physical device to display this information, the server provides a digital copy of the device information to the user through the control interface, enabling easy identification and control without adding physical complexity to the device.
3Productivity
If the user needs to know the correspondent's IP address to communicate, then direct communication can be established, but the user must manually track IP changes which increases operational complexity
Solution Approach 1:
The control server automatically performs IP address management tasks including tracking IP changes, updating mappings, and providing current IP information to users. Instead of requiring users to manually track IP changes, the system self-services by automatically maintaining accurate device information, allowing users to simply query the server for current IP addresses without manual intervention.

AI summary
An apparatus and method control a connection between peripheral devices in a control server of a wireless communication system providing an IP-based communication service. The method for controlling the connection between peripheral devices includes registering at least one device in a group list classified by user identification information. The method also includes, if a control node including a user identifier of the group list requests a control of any one device included in the group list, checking an IP address of the device that is requested to be controlled by the control node. The method further includes sending a control command of the control node using the IP address.
