Personal IoT Network Access Management via AMF Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal Internet of Things (IoT) networks lack efficient methods for managing device access and information processing, particularly in locally managed networks with varying capabilities and communication standards.
Innovation Solution
A method for processing information in personal IoT networks involving a first device that receives a join network request, determines device eligibility, and sends a response, along with an access management function (AMF) that acquires and updates network data for newly joined devices, and a user data management (UDM) that manages network information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a personal IoT network uses local management with multiple devices having varying capabilities, then the network can be more flexible and adaptable, but the complexity of managing device access and maintaining network security increases
Solution Approach 1:
The patent introduces an access management function (AMF) as an intermediary entity that centralizes the management of device access to personal IoT networks. The AMF receives join requests from external devices, determines whether to allow access based on network policies, and coordinates with the personal IoT network's management entities. This intermediary approach maintains network flexibility by allowing diverse devices to join while reducing access management complexity by centralizing authorization decisions in a dedicated component rather than requiring each network device to independently evaluate access requests
Solution Approach 2:
The patent segments the access management functionality into distinct components: the access management function (AMF) handles external device authorization, while the personal IoT network's own management entities (such as the personal network management function) handle internal network operations. This segmentation allows each component to specialize in specific tasks, reducing overall system complexity while maintaining the ability to support diverse device types and capabilities within the personal IoT network
2Reliability
If the network implements comprehensive device access control and information management, then network security and data integrity are improved, but the processing time and operational overhead increase
Solution Approach 1:
The patent implements preliminary action by having the access management function (AMF) perform access authorization decisions before devices are allowed to join the personal IoT network. The AMF evaluates join requests against network policies and determines access permissions in advance, rather than making decisions reactively during network operations. This preliminary authorization reduces processing time during actual network operations while maintaining security, as the authorization framework is established beforehand
Solution Approach 2:
The patent implements feedback mechanisms where the access management function (AMF) receives information about device join requests, makes authorization decisions, and provides responses back to both the requesting devices and the personal IoT network management entities. This feedback loop ensures that security decisions are communicated efficiently, and network management entities can update their state based on authorization outcomes, reducing the need for repeated verification and improving overall processing efficiency
3Reliability
If the network maintains centralized control for security management, then authorization and security are improved, but the device's autonomy and ease of operation are reduced
Solution Approach 1:
The patent applies local quality by allowing different levels of control autonomy for different devices within the personal IoT network. The access management function (AMF) provides centralized authorization control for devices joining from outside the network, ensuring security. However, once devices are authorized members of the personal IoT network, they can operate with greater autonomy and make local decisions about network operations. This differentiated approach maintains security through centralized control where needed while preserving device autonomy for legitimate network members

AI summary
A method for processing information performed by a first device, includes: receiving a join network request of a second device, in which the join network request includes device information of the second device; determining, according to the device information, whether to allow the second device to join a personal Internet of Things network (PIN) to obtain a determination result; and sending a join network response to the second device according to the determination result.
