Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If machine terminals are allowed to access the network freely like ordinary terminals, then the quantity of connected devices and M2M communication capabilities are improved, but the network service load increases and communication quality of ordinary terminals deteriorates
Solution Approach 1:
The patent segments the network access rights by creating different subscription types: ordinary subscriptions for human users and machine-type subscriptions for MTC devices. This segmentation allows the network to treat different terminal types differently, enabling machine terminals to access the network during off-peak hours without affecting ordinary terminal communication quality during peak hours.
Solution Approach 2:
The patent implements periodic action by defining authorized periods and forbidden periods for machine-type subscriptions. During authorized periods (typically off-peak hours), machine terminals are allowed to access the network. During forbidden periods (typically peak hours), machine terminal access is restricted. This periodic control mechanism ensures that machine communication occurs during service valley periods, reducing network congestion and maintaining communication quality for ordinary terminals.
2Productivity
If machine terminals communicate during peak hours, then the productivity of M2M applications is improved, but the network service load increases causing reduced service initiation success ratio
Solution Approach 1:
The patent applies preliminary action by pre-configuring authorized periods for machine-type subscriptions before the communication occurs. The network side determines and notifies the terminal about the authorized periods in advance, allowing machine terminals to plan their communication activities accordingly. This ensures that M2M applications can execute their tasks during predetermined off-peak hours, maintaining productivity while avoiding network congestion that would reduce service initiation success ratio.
3Reliability
If time-controlled subscriptions are implemented to control machine terminal access, then the communication quality of ordinary terminals is improved, but the device complexity increases
Solution Approach 1:
The patent implements self-service by enabling machine terminals to autonomously determine whether they are allowed to access the network based on their subscribed authorized periods. The terminal compares the current time with its stored authorized period information and independently makes access decisions without requiring complex real-time network authentication for each access attempt. This self-service mechanism simplifies the overall system complexity while maintaining effective access control.
Solution Approach 2:
The patent applies dynamics by making the authorized periods configurable and adaptable. The network side can determine, adjust, and notify updated authorized periods to terminals based on changing network conditions, service requirements, or subscription parameters. This dynamic approach allows the system to maintain optimal performance without requiring overly complex static configurations, balancing control effectiveness with system simplicity.

AI summary
Embodiments of the present invention disclose a method, an apparatus, and a system for controlling network access of a machine terminal. In the embodiments of the present invention, an authorized period and/or a forbidden period of a time-controlled subscription is generated according to information such as network service load historical data of a network and application information of the time-controlled subscription. Network access of the machine terminal is controlled according to the authorized period and/or the forbidden period. Because the network access time of the machine terminal can be controlled flexibly, the communication of the machine terminal can be controlled flexibly, and impacts of machine terminal communication on ordinary terminal communication can be reduced.
