AI Technical Summary
In network sharing scenarios, User Equipment (UE) faces challenges with inter-frequency handover due to limited measurement capabilities, leading to increased call drop rates and reduced success rates of inter-frequency handovers, especially in complex network environments where multiple operators share frequencies, resulting in UE measuring invalid neighbor cells and exceeding measurement capacity.
A method and device for determining inter-frequency neighbor cells by acquiring the Public Land Mobile Network Identity Document (PLMN ID) of UE accessing a border region, processing configuration information for inter-frequency handover, and filtering neighbor cells to retain only valid frequencies, allowing UE to perform handovers efficiently, thereby reducing measurement gaps and improving handover success rates.
The solution enhances the success rate of inter-frequency handovers and reduces call drop rates by optimizing the selection and filtering of inter-frequency neighbor cells, ensuring UE measures only valid frequencies, thus improving network performance in shared network environments.
