Multi-Card UE Service Handover via Base Station Decision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-card user equipment (UE) experiences poor service continuity and low service transmission efficiency due to different response algorithms for paging signaling from different communication systems, leading to blind rejection or response to services.
Innovation Solution
A service handover method where a first base station receives a handover request signaling from a multi-card UE, determines whether to allow the handover based on service information from both communication systems, and sends a handover response signaling with configuration information to the UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-card UE uses different response algorithms for paging signaling from different manufacturers, then device compatibility is achieved, but service continuity deteriorates due to blind rejection or response
Solution Approach 1:
The patent changes the parameter of handover decision-making from manufacturer-specific algorithms to standardized service information comparison. By evaluating service information parameters (service type, QoS requirements, data volume) from both communication systems against standardized criteria, the patent eliminates blind rejection/response behaviors while maintaining device compatibility across different manufacturers.
2Speed
If multi-card UE blindly responds to paging signaling from second communication system, then service responsiveness is improved, but service transmission efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by evaluating service information from both communication systems before the UE responds to paging signaling. The base station compares service type, QoS requirements, and data volume parameters in advance, determining whether handover is necessary before the UE commits to responding, thus avoiding unnecessary service interruptions and improving transmission efficiency.

AI summary
The present disclosure relates to a service handover method and apparatus. The service handover method comprises: receiving handover request signaling, sent by a multi-card user equipment, for requesting a handover to a second communication system, wherein the handover request signaling carries second service information, and the second service information is service information of a service to be transmitted, in the second communication system, of the multi-card user equipment; if it is determined, on the basis of first service information and the second service information, that the multi-card user equipment is allowed to execute a handover operation, generating handover response signaling, wherein the handover response signaling carries handover configuration information, and the first service information is service information corresponding to the service to be transmitted, in the first communication system, of the multi-card user equipment; and sending the handover response signaling to the multi-card user equipment. The technical solution of the present disclosure can solve the problems of a poor service continuity and a low service transmission efficiency of a multi-card user equipment caused by the multi-card user equipment rejecting or responding to a service of a second communication system.
