Policy Configuration Segmentation for Gateway and Management PDU Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In personal IoT networks, gateway and management terminals often fail to match protocol data unit (PDU) sessions due to inconsistent policy configurations, leading to low communication reliability.
Innovation Solution
A policy configuration method and apparatus that sends targeted policy information to communication devices, including rule matching information for both gateway and management terminals, allowing them to establish and manage separate PDU sessions effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same policy configuration is applied to both gateway terminals and management terminals, then device complexity is reduced, but communication reliability deteriorates due to inability to correctly match PDU sessions
Solution Approach 1:
The patent segments the policy configuration into two distinct types: first policy information for gateway terminals and second policy information for management terminals. This segmentation allows each terminal type to have customized policy rules appropriate to its function, enabling correct PDU session matching while maintaining clear configuration management.
Solution Approach 2:
The patent applies local quality by providing different policy information characteristics to different terminal types. Gateway terminals receive first policy information with rules suitable for gateway functions, while management terminals receive second policy information with rules suitable for management functions. This localized customization ensures each terminal can correctly match its PDU sessions.
2Reliability
If separate policy configurations are provided for gateway and management terminals, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The network side device provides multi-functionality by handling both first policy information generation/delivery and second policy information generation/delivery. This universal approach consolidates the complexity management at the network side while keeping terminal side implementations relatively simple, each terminal only needing to process its designated policy type.
3Ease of operation
If policy information is not differentiated between terminal types, then ease of operation is improved, but PDU session matching accuracy deteriorates
Solution Approach 1:
The patent segments policy information into distinct categories (first policy information for gateway terminals, second policy information for management terminals) with differentiated rule matching information. This segmentation ensures that each terminal type receives precisely tailored policies, achieving accurate PDU session matching while maintaining operational simplicity through automated network-side delivery.

AI summary
A policy configuration method and apparatus, a terminal, a network-side device, and a non-transitory computer-readable storage medium are disclosed in the field of communication technologies. The method includes: a first core network function sends target information including at least one of first policy information or second policy information to a first communication device. Rule matching information in the first policy information is used to match a first PDU session, and rule matching information in the second policy information is used to match a second PDU session. The first PDU session is used to transmit information between a first device and a first network, and the second PDU session is used to transmit information between the first communication device and the first network. The first device is connected to the first communication device, and the first network is a network corresponding to the first core network function.
