Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 4G/5G systems lack efficient mechanisms for network slicing and unified authentication frameworks, particularly in supporting simultaneous access via both 3GPP and non-3GPP access networks, leading to inefficiencies in resource management and service continuity.
Innovation Solution
The implementation of enhanced 5G core network functionalities, including network slicing and unified authentication, allows for simultaneous access and management across diverse access networks, enabling seamless service continuity and optimized resource allocation through network functions like AMF, SMF, and UPF, with support for multiple network slice instances and edge computing.

Engineering Contradiction Analysis
1Productivity
If network slicing and unified authentication are implemented to support simultaneous access via 3GPP and non-3GPP access networks, then service continuity and resource management efficiency are improved, but system complexity increases
Solution Approach 1:
The system is segmented into distinct network slices, each optimized for specific services or access types. Network slice instances are created to handle different traffic types and access networks separately, allowing independent management and optimization of each slice while maintaining overall system functionality.
Solution Approach 2:
The authentication system is designed with universal functionality to handle both 3GPP and non-3GPP access networks through a unified authentication framework. The same authentication mechanisms and network functions serve multiple access types, reducing the need for separate systems while maintaining service continuity across different access networks.
2Productivity
If multiple network slice instances are supported for optimized resource allocation, then resource utilization efficiency is improved, but management complexity increases
Solution Approach 1:
The system implements feedback mechanisms where network functions continuously monitor resource usage across multiple network slices and dynamically adjust resource allocation. This feedback loop enables automated optimization of resource distribution among slices based on actual demand, reducing manual management complexity while maintaining high resource utilization efficiency.

AI summary
A wireless device sends a first request to a mobility management function via a base station. The first request includes a paging cause indication in a paging message. A first paging message is received by the wireless device and comprises a first paging cause indication. Based on the first paging message, a second request for a connection setup is sent.
