Base Station Restriction Notification for MTCD Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, especially in LTE environments, a large number of Machine-Type Communication Devices (MTCDs) can occupy base station resources, preventing other communication terminal devices from being accommodated.
Innovation Solution
A communication system where a base station notifies communication terminal devices within its range of restriction information, differentiating between restricted MTCDs and other devices, and restricting the operation of MTCDs to prevent resource occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large number of MTCDs are accommodated in the communication system, then the quantity of connected devices increases, but the base station becomes occupied and cannot accommodate other communication terminal devices
Solution Approach 1:
The patent segments the communication terminal devices into two distinct categories: MTCDs (Machine-Type Communication Devices) and other communication terminal devices. This segmentation allows the base station to apply different handling rules and resource allocation strategies for each category, preventing MTCDs from monopolizing base station resources and ensuring that other devices can still be accommodated effectively.
2Object-generated harmful factors
If restriction information is notified to all communication terminal devices, then MTCD operations are restricted, but the notification system becomes more complex
Solution Approach 1:
The patent applies local quality by providing restriction information specifically targeted at MTCDs through their dedicated control channel, while other communication terminal devices receive different or no restriction information. This targeted approach restricts MTCD operations to prevent resource occupation without requiring a universally complex notification system that would affect all devices equally.

AI summary
A communication system includes a base station device, and a plurality of communication terminal devices configured to perform radio communication with the base station device. The plurality of communication terminal devices include a restricted terminal device having a restricted operation, the base station device is configured to notify, via System Information (SI), at least one communication terminal device located within a communicable range of the base station device of restricted operation information that is information on the restricted operation of the restricted terminal device. The at least one communication terminal device notified of the restricted operation information judges whether or not the at least one communication terminal device is the restricted terminal device based on information stored in a subscriber identity module (SIM) of the at least one communication terminal device.
