Dedicated Core Network Handover via Type Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handover procedures in mobile communication networks fail to ensure that user equipment (UE) is transferred to a target dedicated core network element of the same type as the current one, leading to difficulties in maintaining dedicated network management across different UE types.
Innovation Solution
A first dedicated CN network element notifies a target CN network element of the UE's CN type, allowing it to determine and hand over the UE to a corresponding dedicated CN network element that supports the same CN type, ensuring seamless registration and management within the dedicated network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing handover procedure is used, then handover process is simple, but UE cannot be ensured to be handed over to target dedicated CN network element of same CN type
Solution Approach 1:
The source dedicated CN network element performs preliminary actions by notifying the target CN network element of the UE's CN type information before the handover is executed. This advance notification ensures that the target element is prepared to receive and properly handle the UE with the specific CN type, guaranteeing that the handover reaches the correct dedicated network element without compromising procedural simplicity
Solution Approach 2:
The target CN network element acts as an intermediary that receives the UE's CN type information from the source element, processes this information to identify the appropriate dedicated CN network element, and then facilitates the handover to the correct target element. This intermediary role ensures accurate routing while maintaining the efficiency of the handover process
2Adaptability or versatility
If dedicated core networks are deployed for different UE types, then dedicated network management is achieved, but handover between dedicated networks becomes complex
Solution Approach 1:
The handover procedure is designed with universal applicability across different CN types. The source dedicated CN network element notifies the target element of the UE's CN type, and the target element uses this information to identify the appropriate dedicated CN network element. This universal approach allows the same handover mechanism to work across multiple dedicated networks while maintaining their specific management requirements
Solution Approach 2:
The system implements feedback by notifying the target CN network element of the UE's CN type information before handover. This feedback loop ensures that the target element can make informed decisions about the appropriate dedicated CN network element for handover, enabling dedicated network management without significantly increasing procedural complexity

AI summary
The present invention discloses a dedicated network handover method, a dedicated network type notification method, and a device, so as to ensure that UE is handed over to a dedicated CN network element of a corresponding CN type in a handover process. The CN network element device mainly includes: a receiving module, configured to receive CN type information of user equipment UE sent by a first dedicated CN network element; a determining module, configured to determine, according to the CN type information received by the receiving module, identifier information of a second dedicated CN network element that supports a CN type indicated by the CN type information; and a handover module, configured to hand over, according to the identifier information determined by the determining module, the UE to the second dedicated CN network element corresponding to the identifier information.
