Base Station Unnecessary Handover Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining unnecessary handovers in radio communications rely on a fixed time threshold for all services and UEs, leading to performance penalties due to improper handover parameter configuration and failure to consider UE-specific requirements.
Innovation Solution
A method that determines unnecessary handovers by using time thresholds corresponding to UE characteristic attribute parameters, such as service type, QoS, and SPID, to differentiate and optimize handover decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed time threshold is used for all services and UEs to determine unnecessary handovers, then the handover determination process is simple and uniform, but it causes performance penalties because it fails to consider UE-specific requirements and leads to improper handover parameter configuration
Solution Approach 1:
The patent applies local quality by transitioning from a uniform fixed time threshold to UE-specific time thresholds based on characteristic attribute parameters. Each UE is assigned a time threshold tailored to its service type, mobility pattern, and quality of service requirements, allowing the handover determination process to adapt to local UE-specific conditions rather than applying a one-size-fits-all approach.
Solution Approach 2:
The patent changes the parameter from a fixed time threshold to a variable time threshold that depends on UE characteristic attribute parameters. The time threshold is dynamically adjusted based on UE-specific parameters such as service type, mobility speed, and QoS requirements, enabling more accurate handover determination while reducing unnecessary handovers.
2Reliability
If UE-specific time thresholds based on characteristic attribute parameters are used to determine unnecessary handovers, then handover decision accuracy and user experience are improved, but the system complexity increases due to the need to manage multiple UE-specific parameters
Solution Approach 1:
The patent applies universality by establishing a standardized framework where time thresholds are determined based on UE characteristic attribute parameters that can be universally applied across different UE types and service scenarios. The same determination mechanism works for various service types (voice, data, video) and mobility conditions, eliminating the need for separate handover determination logic for each scenario.
Solution Approach 2:
The patent applies preliminary action by pre-configuring and storing time threshold values corresponding to different UE characteristic attribute parameters before handover determination is needed. The base station retrieves the appropriate time threshold based on the UE's current characteristics, avoiding the need to calculate or determine thresholds in real-time and reducing processing complexity.
3Device complexity
If a fixed time threshold is used for handover determination, then the base station configuration is simple, but it leads to unnecessary handovers and increased signaling overhead
Solution Approach 1:
The patent changes the handover determination parameter from a fixed time threshold to a UE-specific time threshold based on characteristic attribute parameters. This allows the base station to accurately identify unnecessary handovers by comparing the actual time of stay against the UE-specific threshold, thereby reducing unnecessary handovers and associated signaling overhead while maintaining configuration simplicity.

AI summary
The present invention provides a method for determining an unnecessary handover and a base station. The method includes: if a user equipment UE is handed over from a first cell to a second cell, and then handed over from the second cell to a third cell, determining, by a base station, a time threshold corresponding to a UE characteristic attribute parameter of the UE, and a time of stay of the UE in the second cell; determining, by the base station according to the time threshold corresponding to a UE characteristic attribute and the time of stay of the UE in the second cell that are determined, whether an unnecessary handover of the UE occurs; and determining that an unnecessary handover of the UE occurs if the time of stay is shorter than the time threshold. The present invention optimizes a method for determining whether an unnecessary handover occurs.
