Silent Retry Synchronization Detection for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to detect and correct synchronization mismatches between mobile stations and base stations, leading to failed connections and user frustration, with previous systems unable to identify unsynchronized components and take corrective action.
Innovation Solution
A system and method that determines synchronization between a base station and a mobile station by comparing their operational states, taking corrective action to resynchronize them, and initiating a silent retry upon detection of non-synchronization, thereby establishing communications efficiently and conserving system resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system performs silent retry without synchronization detection, then connection establishment may eventually succeed, but system resources are wasted and user experience deteriorates
Solution Approach 1:
The base station performs preliminary synchronization detection by comparing its state machine state with the mobile station's reported state before allowing silent retry to proceed. This preliminary check prevents resource waste by identifying synchronization mismatches early, before unnecessary retry attempts are made.
Solution Approach 2:
The mobile station provides feedback about its state machine state to the base station. The base station uses this feedback to determine whether it and the mobile station are synchronized. This feedback mechanism enables the system to detect synchronization issues and prevent futile retry attempts.
2Reliability
If the system attempts silent retry without synchronization detection, then connection may be established eventually, but user frustration increases due to delayed connection
Solution Approach 1:
The base station performs preliminary synchronization detection before allowing silent retry to proceed. This early detection prevents time loss by identifying synchronization mismatches before the system enters a prolonged retry cycle, thereby reducing connection establishment delay.
Solution Approach 2:
The mobile station's state information is fed back to the base station, enabling real-time synchronization status determination. This feedback allows the system to quickly detect and respond to synchronization issues, minimizing the time users wait for connection establishment.
3Device complexity
If the system does not detect synchronization status, then the system operation remains simple, but the system cannot take corrective action when out of synchronization
Solution Approach 1:
The mobile station feeds back its state machine state to the base station, which uses this information to determine synchronization status. This feedback mechanism adds minimal complexity while enabling the system to detect and correct synchronization issues, thereby improving reliability.
Solution Approach 2:
The base station autonomously determines synchronization status by comparing its own state with the mobile station's reported state. This self-service approach allows the system to detect and correct synchronization issues without requiring complex external monitoring or intervention.

AI summary
A system and method for synchronizing the operation of a wireless mobile station (102) and a base station (104) includes receiving a message at the base station (104) indicating a state of operation of the wireless mobile station (102). A determination is made as to whether the base station (104) and the mobile station (102) are in synchronization based upon comparing the state of operation of the mobile station (102) and a state of operation of the base station (104).
