Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks managed by communications companies face challenges in quickly connecting new users and changing communication services, particularly during busy periods, leading to prolonged service delays.
Innovation Solution
A communication system and method that enables users to construct and change communication networks independently by integrating a first transmission device with a control server via optical transmission lines, allowing for the construction of control, data, and customer control networks without direct intervention from the communications company, using multiplexing and demultiplexing techniques to manage multiple network signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communications company constructs and manages the entire communication network including control network and data network, then the network construction is reliable and controlled, but the time required to connect new users and change services is excessively long
Solution Approach 1:
The communication network is segmented into three independent networks: control network (for device control), data network (for user data transmission), and customer control network (for service management). This segmentation allows different parts of the system to operate independently, enabling users to quickly establish data networks while the control network remains managed by the communications company for reliability.
Solution Approach 2:
Users are empowered to independently construct and manage their own data networks and customer control networks without requiring direct intervention from the communications company. Users can connect new devices and change services by themselves through the customer control network, dramatically reducing service setup time while the control network ensures overall system reliability.
2Manufacturing precision
If the communications company manually reconstructs the communication network for each new user or service change, then the network configuration is precise and controlled, but the process is extremely time-consuming and inefficient
Solution Approach 1:
The control network is pre-configured and established by the communications company with all necessary control functions in place before users need services. This preliminary setup includes control servers, management systems, and basic network infrastructure, so that when users need to connect or change services, they can do so immediately without waiting for manual configuration.
Solution Approach 2:
A customer control network acts as an intermediary between users and the communications company's control network. This intermediary network includes customer control servers that handle service requests, device management, and configuration changes automatically, eliminating the need for manual intervention while maintaining precise control over network operations.
3Adaptability or versatility
If the customer control server manages all network information including internal network data, then the server has complete control, but the server becomes a bottleneck and cannot respond quickly to user requests
Solution Approach 1:
The management of specific network information is extracted from the customer control server and distributed to appropriate network elements. The customer control server retains only customer-related information and service management functions, while detailed network configuration and control data are managed by the control network's control servers. This extraction reduces the customer control server's workload and improves response speed.
Solution Approach 2:
The system transitions from a single-server architecture to a multi-dimensional distributed architecture where different types of information are managed at different levels: customer control server handles service-level information, while control network servers handle network-level information. This dimensional separation allows parallel processing and eliminates bottlenecks.

AI summary
A communication system is a communication system that includes: a plurality of transmission devices; a setting server that receives an instruction to change data related to setting of a data network; and a control server that performs a control process related to the plurality of transmission devices and the data network on a basis of the data. In the communication system, a setting processing unit is provided to perform a process for constructing a customer control network between a first transmission device and the setting server by using a second transmission device as a relay device, when the first transmission device and the second transmission device are connected by an optical transmission line. The first transmission device includes: a connection processing unit that performs a process for constructing a control network between the first transmission device and the control server by using the second transmission device as a relay device, when the first transmission device and the second transmission device are connected by the optical transmission line; and a device control unit that performs a process for constructing the data network for the first transmission device by using the second transmission device as a relay device, when the first transmission device and the second transmission device are connected by the optical transmission line.
