Network Device Core Network Selection Indication for IoT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in determining the appropriate core network for UE devices supporting EPS CIoT and 5G CIoT features when they select between NB-IoT/WB-E-UTRA cells and 5G core networks, leading to inefficiencies in network access and processing.
Innovation Solution
The method involves transmitting first indication information from a network device to a terminal device to assist in selecting a target core network type and/or target core network, allowing the UE to choose based on supported features or predefined rules, thereby improving access efficiency.

Engineering Contradiction Analysis
1Productivity
If the network device transmits first indication information to assist terminal device in selecting core network, then the access efficiency is improved, but the device complexity increases due to additional information transmission and processing requirements
Solution Approach 1:
The network device performs preliminary action by transmitting first indication information about available core networks before the terminal device attempts to access. This advance information provision enables the terminal device to pre-determine the target core network, avoiding unnecessary access attempts and improving overall access efficiency while distributing the complexity burden to the network device rather than the terminal device
2Device complexity
If the terminal device autonomously determines core network selection, then the device complexity is reduced, but the access efficiency deteriorates due to lack of guidance information
Solution Approach 1:
The first indication information acts as an intermediary that bridges the network device and terminal device in the core network selection process. It provides essential guidance information to the terminal device without requiring complex autonomous decision-making capabilities, thereby maintaining low device complexity while significantly improving access efficiency through informed selection
