WTRU PIN Policy Management via Core Network Slicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in managing and authorizing connectivity within Personal Internet of Things (PIN) networks, particularly in establishing and maintaining connections between PIN elements, a PIN Gateway (GW), and the core network (CN).
Innovation Solution
The implementation of a wireless transmit/receive unit (WTRU) with circuitry that enables sending PIN policy requests, receiving PIN policies, sending PIN connectivity policies, and establishing connections with the core network based on data network name (DNN) and slice information. This WTRU forwards data between the core network and PIN elements according to traffic forwarding parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional IoT network management is used, then device connectivity can be established, but authorization and policy management become complex and difficult to control
Solution Approach 1:
The patent introduces a Policy Management Function (PMF) as an intermediary component that centralizes authorization and policy management. The PMF receives connectivity requests from WTRUs, evaluates them against predefined policies, and makes authorization decisions. This mediator approach simplifies the complexity by separating the decision-making logic from the execution层面, allowing centralized control of PIN network connectivity while reducing the burden on individual devices to manage complex authorization rules.
2Reliability
If connectivity policies are centrally managed, then authorization control is improved, but network response time increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring and storing authorization policies in the PMF before actual connectivity requests occur. When a WTRU sends a connectivity request, the PMF can immediately evaluate it against the pre-stored policies without requiring real-time policy generation or complex computations. This preliminary preparation of policy rules enables fast authorization decisions while maintaining centralized control, effectively reducing the time loss associated with centralized management.
3Adaptability or versatility
If multiple PIN elements connect to core network, then network functionality is enhanced, but connection management complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the connection management function into separate components: the PMF handles high-level policy decisions and authorization, while individual WTRUs handle their own connectivity establishment and maintenance. This segmentation allows multiple PIN elements to connect to the core network independently and simultaneously, enhancing network functionality and adaptability. Each WTRU manages its own connection lifecycle, reducing the overall management complexity compared to a centralized approach where the network would need to track and control every individual connection detail.
