Mobile Station Neighbor Cell Information Validity Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional GERAN communication systems waste time and resources by transmitting redundant neighbor cell information to mobile stations, which can delay cell reselection and call re-establishment processes.
Innovation Solution
Mobile stations monitor channels to determine neighbor cell information and send validity indications to the network, allowing it to omit sending redundant information, thereby reducing unnecessary transmissions and improving mobility procedure efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network transmits neighbor cell information to mobile stations to facilitate mobility procedures, then mobility procedures (cell reselection and call re-establishment) can be performed, but redundant transmissions waste radio resources and increase transmission time
Solution Approach 1:
The mobile station performs preliminary actions by monitoring channels and determining neighbor cell information before the network would normally transmit it. The mobile station stores this information and sends a validity indication to the network, allowing the network to skip redundant transmissions and proceed directly with mobility procedures.
2Manufacturing precision
If the mobile station waits to receive sufficient neighbor cell system information before concluding mobility procedures, then the procedures can be completed with accurate information, but the process takes longer and may miss completion time periods
Solution Approach 1:
The mobile station performs preliminary information gathering by monitoring channels and determining neighbor cell information before the network would normally transmit it. This pre-acquired information is stored and validated, allowing the mobile station to immediately use it for mobility procedures without waiting for network transmissions, thus reducing procedure duration while maintaining information accuracy.
3Reliability
If the network provides complete neighbor cell system information to ensure successful mobility procedures, then reliability of mobility procedures improves, but transmission time and resource consumption increase
Solution Approach 1:
The mobile station sends feedback to the network in the form of a validity indication, informing the network about the status of neighbor cell information already possessed. This feedback mechanism allows the network to adapt its transmission strategy, sending only necessary information or skipping transmissions when information is already valid, thereby reducing transmission time while ensuring reliability.

AI summary
Methods and apparatus to avoid transmission of redundant neighbor cell information to mobile stations. An example method to avoid transmission of at least some neighbor cell system information from a network to a mobile station disclosed herein comprises receiving neighbor cell system information, setting a validity indication representing whether the mobile station has valid neighbor cell system information associated with a neighbor cell, and sending the validity indication to the network.
