Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing is implemented to support multiple access types and services, then service versatility and adaptability are improved, but device complexity and management difficulty increase
Solution Approach 1:
The patent segments the core network into multiple independent network slices, each tailored for specific services or access types. This segmentation allows versatile service support while managing complexity through modular, isolated slice management rather than monolithic system control
Solution Approach 2:
The patent implements a universal service request handling mechanism that can process requests across different network slices and access types through a common interface. This multi-functionality approach maintains service versatility while reducing management complexity by providing unified procedures
2Productivity
If unified policy frameworks and service-based interactions are implemented, then network efficiency and service continuity are improved, but device complexity increases
Solution Approach 1:
The patent introduces service-based interaction interfaces as intermediaries between different network functions and access networks. These standardized interfaces improve network efficiency through automated service delivery while managing complexity by providing clear, defined interaction protocols between components
Solution Approach 2:
The patent implements service request procedures that establish service contexts and policies in advance before actual data transmission. This preliminary configuration improves network efficiency by pre-resourcing services while reducing operational complexity during active service delivery
3Loss of time
If localized data network access and edge computing are deployed, then service latency is reduced, but network infrastructure complexity increases
Solution Approach 1:
The patent extends network architecture into edge dimensions by deploying localized data network access points closer to users. This spatial dimensionality change reduces transmission latency while managing infrastructure complexity through hierarchical organization of edge and core network functions

AI summary
An access and mobility management function (AMF) receives from a first wireless device a non-access stratum (NAS) message comprising an identifier (ID) of a group communication session. The AMF receives from a session management function (SMF) a message comprising a list of one or more second wireless devices associated with the group communication session and a list of one or more packet data unit (PDU) sessions. The AMF determines, based on a state of the one or more second wireless devices, to page the one or more second wireless devices. The AMF receives from the one or more second wireless devices one or more service request messages.
