Base Station Handover Using Core Network Compatibility Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, inter-base station handover efficiency is compromised when the target base station's core network cannot provide the required communication service for the User Equipment (UE), leading to normal operation issues.
Innovation Solution
Incorporating core network type information in the handover request and response to ensure the target base station can reject or allow handover based on its connected core networks, thereby matching the UE's service requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If inter-base station handover is performed without checking core network compatibility, then handover speed is improved, but UE service reliability deteriorates
Solution Approach 1:
The patent applies preliminary action by including core network type information in the handover request message before the handover is executed. The target base station checks compatibility between the UE's required core network type and the target base station's connected core networks in advance, and only sends a handover confirm message if compatible. This prevents incompatible handovers from occurring, ensuring UE service reliability while maintaining fast handover execution.
2Reliability
If core network type information is included in handover request and response messages, then handover compatibility is improved, but message complexity increases
Solution Approach 1:
The patent applies parameter changes by adding core network type information fields to existing handover request and response messages. Specifically, the handover request message includes a core network type indicator parameter, and the handover response message includes a core network type match indicator parameter. This approach enhances handover compatibility by providing necessary compatibility information while minimizing message structure changes, thus controlling message complexity.
3Stability of the object's composition
If target base station checks core network compatibility before handover confirmation, then service continuity is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by performing the core network compatibility check during the handover request processing stage, before the handover is executed. The target base station receives the handover request containing the UE's required core network type, checks whether it has a matching connected core network, and only proceeds to send handover confirm if compatible. This ensures service continuity is maintained while the compatibility verification is completed in advance, minimizing actual handover processing time.

AI summary
Disclosed are a handover method for between base stations, and a device, system and storage medium, which belong to the field of wireless communications. The method comprises: sending a handover request to a target base station, wherein the handover request carries type information of a core network, the type information of a core network being used for indicating the type of core network which the user equipment (UE) to be handed over between base stations needs to access; receiving a handover response sent from the target base station, wherein the handover response is used for indicating whether the target base station allows the UE to be handed over to the target base station, and the handover response is sent by the target base station according to the type information of a core network and the type of at least one core network connected to the target base station. The present disclosure is capable of improving handover efficiency between base stations.
