MTC Subscription Control Validation for Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for subscription control in Machine-Type Communication (MTC) systems lack effective mechanisms to ensure that MTC devices are properly subscribed to required features, leading to unsuccessful service triggers and wastage of network resources due to mismatched features and capability issues.
Innovation Solution
A method for subscription control in a mobile communication system that involves validating trigger requests by checking if required MTC features are subscribed and supported by the network control node, and rejecting requests if they are not, thereby ensuring valid and capable network resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If subscription control validation is implemented to check MTC feature subscriptions, then service trigger reliability is improved, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent applies preliminary action by performing subscription validation checks before triggering MTC services. The network control node validates whether the MTC device has subscribed to required features (such as device trigger, subscription control, and data communication features) before allowing service activation. This prevents unnecessary service attempts and ensures reliability while managing complexity through structured validation procedures.
Solution Approach 2:
The patent implements feedback mechanisms where the network control node receives subscription information from the MTC device, validates it against required features, and provides appropriate responses. If validation fails, the system feedbacks rejection messages to prevent resource wastage. This feedback loop ensures reliable service triggering while maintaining controlled processing complexity through standardized validation protocols.
2Speed
If all MTC devices are allowed to receive service triggers without validation, then service delivery speed is improved, but network resource wastage increases
Solution Approach 1:
The patent performs preliminary subscription validation checks before service trigger delivery. The network control node verifies that MTC devices have appropriate feature subscriptions (device trigger, subscription control, data communication features) before activating services. This preliminary filtering prevents network resource wastage by avoiding service delivery to unqualified devices while maintaining efficient service activation for validated devices.
3Reliability
If subscription validation checks are performed for each trigger request, then feature mismatch errors are reduced, but processing time increases
Solution Approach 1:
The patent performs subscription validation as a preliminary step before service trigger processing. The network control node checks whether required MTC features are subscribed before proceeding with service activation. By structuring validation as a preliminary filter, the system reduces feature mismatch errors and ensures accuracy while managing processing time through efficient validation logic that quickly identifies qualified devices.

AI summary
A method of subscription control for a first network control node in a mobile communication environment is disclosed. The method comprises receiving a trigger request message for triggering a mobile communication device from a machine-type communication (MTC) server, determining whether the trigger request message is valid according to whether one or more MTC features required by an application indicated in the trigger request message is subscribed or activated by the mobile communication device and is supported by a network control node of the mobile communication system, and accepting the trigger request message and forwarding the trigger request message to the network control node when the trigger request message is determined to be valid.
