Blocking Delivery Service for IoT Messaging Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Class of Service (CoS) mechanisms are inadequate for managing selective message delivery for IoT devices, as they cannot support all types of messaging restrictions and can only assign one CoS per IoT device, limiting flexibility and requiring CoS to be used for different purposes.
Innovation Solution
A blocking delivery service that uses an addressing scheme to identify and manage the delivery of application service data for IoT devices and other end devices, allowing or blocking messages based on configurable criteria such as carrier networks, international or off-network destinations, without relying on CoS or subscriber provisioning, and can generate error messages for blocked messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Class of Service (CoS) mechanisms are used to manage message delivery for IoT devices, then message delivery control is provided, but flexibility is limited because only one CoS can be assigned per device and CoS cannot support all types of messaging restrictions
Solution Approach 1:
The patent segments the single CoS mechanism into multiple independent delivery service rules, where each rule can handle specific messaging restrictions independently. Instead of forcing all restrictions into one CoS, the system creates separate rules for different restriction types (e.g., international messaging, off-network messaging), allowing each to be managed separately while maintaining overall control.
Solution Approach 2:
The delivery service rule mechanism is designed to be universal, replacing the limited CoS system. A single delivery service rule framework can handle multiple types of messaging restrictions that previously required different CoS configurations, making the system more versatile while simplifying the assignment process.
2Adaptability or versatility
If one CoS is assigned per IoT device, then device management is simplified, but the ability to support multiple messaging restriction types is lost
Solution Approach 1:
The system transitions from static CoS assignment to dynamic delivery service rules. Instead of assigning a fixed CoS that must cover all restriction types, the system dynamically evaluates messages against multiple specific rules, allowing flexible configuration without increasing operational complexity. Each rule can be independently configured and applied only when relevant.
3Ease of operation
If CoS mechanisms are used for message delivery control, then basic service management is achieved, but selective delivery management for different message types is problematic
Solution Approach 1:
The patent applies local quality by creating specific delivery rules for different message characteristics rather than using a general CoS mechanism. Each rule is tailored to specific local conditions (e.g., international destinations, off-network destinations, specific message types), allowing precise control over selective delivery while maintaining ease of operation through standardized rule evaluation.
Data Source
AI summary
A method, a device, and a non-transitory storage medium are described in which an blocking delivery service is provided. The service may use an identifier of a source end device, destination address information associated with a destination end device, and configurable criteria as a basis to block delivery of application service layer data. The service may be configured to apply to end devices based on an addressing scheme of the service. The service may be configured on a network device that provides an application service. The service may block delivery without the use of class of service or subscriber provisioning.
