Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical access services, the CBRS technology faces challenges in accurately calculating interference amounts due to inaccurate position information from interfering devices, especially when they are installed indoors and position registration is left to subscribers, leading to potential falsification and errors in interference calculations.
Innovation Solution
An interference control system that includes a processor unit, memory, and subscriber database to accurately convert and transmit position information from interfering devices to a control device, ensuring correct interference calculations by registering accurate position information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If subscribers are responsible for registering position information of interfering devices, then the system is easy to operate and deploy, but the position information accuracy deteriorates due to potential falsification or errors
Solution Approach 1:
The patent introduces a link-up device as an intermediary between the interfering device and the control device. The link-up device receives the registration application from the interfering device, verifies the position information against a subscriber database, and only transmits accurate position information to the control device if verification succeeds. This mediator approach maintains ease of deployment while ensuring position information accuracy.
2Extent of automation
If GPS function is used to acquire position information, then automatic position registration is achieved, but indoor installation scenarios result in inaccurate or unavailable position data
Solution Approach 1:
The link-up device acts as an intermediary that verifies position information regardless of its source. When GPS data is unavailable or inaccurate (such as in indoor scenarios), the system can fall back to alternative position information from the subscriber database, ensuring accurate position data is transmitted to the control device for interference calculation.
3Productivity
If a large number of interfering devices are deployed in the network, then service coverage and capacity are improved, but the complexity of interference calculation and control increases
Solution Approach 1:
The patent implements preliminary verification of position information at the link-up device before transmission to the control device. By pre-filtering and validating position data from multiple interfering devices, the system reduces the burden on the control device, enabling it to efficiently calculate total interference even when a large number of devices are deployed.
4Speed
If position information is not accurately verified, then the system operates with high speed and simplicity, but the interference calculation accuracy deteriorates leading to inadequate protection of interfered devices
Solution Approach 1:
The link-up device serves as an intermediary that performs verification of position information against the subscriber database. This verification process ensures that only accurate position information is transmitted to the control device, maintaining high interference calculation accuracy while the automated nature of the verification keeps the processing speed high.
Data Source
AI summary
Provided is an interference control system for wireless communication suitable for limiting the total amount of interference given to an interfered device to be protected by a large number of interfering devices. An interference control system includes a subscriber database that stores information regarding a position of each interfering device. A registration application (5) including an ID of an interfering device disposed in a carrier network is received from the interfering device. The registration application is received and position information that matches information stored in the subscriber database regarding the ID is set (2), (3), and (6). The position information is transmitted to the control device for registration (6).
