Adaptive Base Station Synchronization for Wireless Handoff Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems experience delays and resource overburden during mobile station handoffs due to inefficient data synchronization techniques, such as data flooding and unnecessary synchronization signals, which lead to redundant data transmission and increased traffic volumes.
Innovation Solution
A method and apparatus for monitoring factors in a wireless communication system to adaptively send synchronization signals to neighboring base transceiver stations based on predetermined functions, optimizing data synchronization by predicting data sets and reducing redundant data transmission during handoffs.

Engineering Contradiction Analysis
1Loss of time
If data is flooded to every base transceiver station at high frequency or at certain intervals, then handoff delay is reduced, but data traffic volume increases and system resources are overtaxed
Solution Approach 1:
The patent applies local quality by sending synchronization data selectively to specific neighboring base transceiver stations based on their geographical location and relevance to the mobile station, rather than flooding all stations with data. This targeted approach reduces unnecessary data traffic while maintaining handoff readiness for stations that actually need the data.
Solution Approach 2:
The patent implements preliminary action by proactively sending synchronization data to neighboring base transceiver stations before handoff is actually needed. This advance preparation ensures that target stations have the necessary data ready when handoff occurs, reducing handoff delay without requiring continuous high-frequency data flooding.
2Reliability
If synchronization signals are sent to all neighboring base transceiver stations, then data synchronization is improved, but system burden and inefficiency increase
Solution Approach 1:
The patent applies local quality by differentiating which neighboring base transceiver stations receive synchronization signals based on their specific characteristics, such as signal strength, distance from the mobile station, and current load. This selective synchronization approach maintains data reliability for relevant stations while reducing the overall system burden by excluding stations that don't require synchronization.
3Reliability
If data is sent to multiple base transceiver stations, then handoff readiness is improved, but redundant data transmission increases
Solution Approach 1:
The patent implements preliminary action by sending synchronization data in advance to neighboring base transceiver stations before handoff is initiated. This advance notification allows target stations to prepare their data buffers and ensure handoff readiness without requiring continuous or redundant data transmission during the actual handoff process, thereby reducing energy waste.

AI summary
An apparatus and method for monitoring (310) at least one factor relating to a wireless communication system (100) is provided such that a synchronization signal is sent (320) to at least one base transceiver station (130) neighboring a primary base transceiver station (120) at least in part according to a predetermined function of the monitored factor(s). The monitored factor may be any of several factors that weigh on the operation of the wireless communication system. The synchronization signal itself may vary in how it signals to the neighboring base transceiver station(s) (130) to synchronize with the data to be sent to a given mobile station (110) from its primary base transceiver station (120), and the number of synchronization signals sent over a given time may vary according to the predetermined function of the monitored factor(s).
