Base Station Network Selection via Core Node Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face increased access delay and inefficiencies due to the inability of base stations to accurately distinguish between different types of user equipment (UE) and service types, leading to unnecessary re-routing and resource wastage, especially when UE moves between base stations or access technologies.
Innovation Solution
A method and system where a base station receives and analyzes messages from network entities and UE to determine the appropriate core network node based on supported service types, reducing re-routing and optimizing network selection by acquiring and utilizing core network type information to select the most suitable core network node for the UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated core network is deployed for specific types of UE, then network service coverage and adaptability are improved, but UE access delay increases due to re-routing between core network nodes
Solution Approach 1:
The base station performs preliminary classification of UE based on service types before UE access requests are processed. By pre-establishing the mapping relationship between service types and core network nodes, and performing service type classification in advance, the system avoids re-routing delays during actual access, thus resolving the contradiction between network adaptability and access speed
Solution Approach 2:
The base station acts as an intermediary that receives service type information from UE, classifies it, and selects the appropriate core network node accordingly. This intermediary function enables direct routing to the correct core network node without requiring re-routing, thereby maintaining both network adaptability for multiple service types and fast access delay
2Device complexity
If the base station cannot distinguish between different types of UE and service types, then network configuration complexity is reduced, but re-routing occurs frequently causing resource wastage
Solution Approach 1:
The network is segmented by service types, with different core network nodes dedicated to different service types. The base station segments incoming access requests by classifying UE service types, and routes each segment to the appropriate core network node. This segmentation enables accurate routing without requiring complex overall network reconfiguration, thus reducing resource wastage while maintaining manageable complexity
Solution Approach 2:
The system changes the parameter of service type classification to enable the base station to distinguish between different UE types. By introducing service type as a classification parameter and establishing its mapping relationship with core network nodes, the system achieves accurate routing without excessive complexity, thereby preventing resource wastage from re-routing

AI summary
A network selection method is provided that includes acquiring, by a first base station, core network type information of a core network node from UE, a second base station or a first core network node; and selecting, by the first station, a core network node for the UE according to the acquired core network type information and information about a second core network node provided by the UE.
