Application Entity Resource Segmentation for IoT Link Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication protocols in IoT technology face challenges in ensuring continuity and reliability of communication services due to resource unavailability and link switching, as they do not allow for seamless re-registration of application entities with new communication nodes, leading to service interruptions.
Innovation Solution
The method involves creating multiple resources for an application entity with unique identifiers and availability attributes, allowing for smooth switching between communication links and ensuring continuous service by re-registering the entity with new nodes when the link changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single resource is registered for an application entity with a communication node, then the registration process is simple, but communication service is interrupted when the communication link switches or resource becomes unavailable
Solution Approach 1:
The patent segments the resource registration by creating multiple independent resources (first resource and second resource) for the same application entity, each with unique identifiers. This segmentation allows the system to switch between resources when one becomes unavailable, thereby improving communication service continuity without requiring complex dynamic reconfiguration protocols
Solution Approach 2:
The patent implements preliminary action by pre-creating multiple resources for an application entity before communication link switching occurs. When the first communication link switches to a second communication link, the application entity can immediately use the pre-existing second resource for re-registration, avoiding service interruption. This eliminates the need for complex real-time resource allocation mechanisms during link switching
2Reliability
If multiple resources are created for an application entity, then communication service continuity is improved, but the system complexity increases
Solution Approach 1:
The patent uses copying by creating a second resource that is essentially a copy of the first resource structure, both serving the same application entity with identical functional attributes. Each resource contains unique identifiers and availability attributes, allowing the system to switch between copies without complex management overhead. This copying approach simplifies resource management while ensuring service continuity
3Reliability
If re-registration is not allowed during link switching, then the protocol is simple, but communication service is interrupted
Solution Approach 1:
The patent applies preliminary action by pre-establishing multiple resources before link switching occurs. When link switching is detected, the application entity can immediately re-register with the new communication node using the pre-existing second resource, without requiring complex dynamic resource creation or modification protocols during the switching process
Solution Approach 2:
The patent implements dynamics by enabling the application entity to dynamically switch between the first resource and second resource based on communication link status. The system maintains flexibility through unique identifiers and availability attributes that allow adaptive resource selection, improving service availability without requiring overly complex protocol mechanisms

AI summary
Disclosed are a method for creating a resource for an application entity, a method for application entity registration, a communication node device and a terminal device. A first resource is created according to a first registration request, wherein the first resource comprises a first identifier, such that the application entity is associated with the first resource through the first identifier (S1); and a second resource is created according to a second registration request, wherein the second resource comprises a second identifier, such that the application entity is associated with the second resource through the second identifier (S2). According to the method and device of the disclosure, the continuity and reliability of a communication service can be improved.
