Cluster System Mobile Station Location Tracking via Dedicated Service Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for uploading GPS information in cluster systems face inefficiencies and resource limitations, particularly in terms of channel resource utilization and bearer capacity, especially when dealing with a large number of mobile stations, which can affect voice call services and GPS information transmission reliability.
Innovation Solution
Configuring a location tracking data service channel with the same frequency as the control channel but a different time slot, allowing for time division multiplexing and enabling mobile stations to monitor both channels without frequency switching, thereby improving resource utilization and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS information is uploaded using control channel random access, then mobile stations can transmit location information, but control channel load increases and voice call service quality deteriorates
Solution Approach 1:
The patent segments the control channel functionality by extracting GPS information transmission to a dedicated service channel. This separation allows the control channel to focus on call management while the service channel handles location information, resolving the resource conflict between voice calls and GPS uploads.
Solution Approach 2:
The patent extracts GPS information transmission from the control channel and places it on a dedicated service channel. This extraction removes the harmful load from the control channel while maintaining GPS transmission capability, directly addressing the technical contradiction.
2Productivity
If a dedicated service data channel is used for mobile station groups, then resource utilization improves for large groups, but channel utilization rate decreases for small groups
Solution Approach 1:
The patent implements dynamic resource allocation where the dedicated service channel is activated only when needed for GPS information transmission. The system can flexibly switch between using the control channel for small groups and the service channel for larger groups, optimizing resource utilization based on actual demand.
Solution Approach 2:
The patent changes the operational parameters of the communication system by introducing a dedicated service channel with specific timing and frequency characteristics. This allows the system to adapt to different group sizes and transmission requirements, improving overall productivity while maintaining efficient resource use.
3Reliability
If mobile stations perform frequency switching to monitor service channels, then GPS information can be transmitted, but power consumption increases
Solution Approach 1:
The patent merges the control channel and service channel frequencies, allowing mobile stations to monitor both channels simultaneously at the same frequency. This eliminates the need for frequency switching while maintaining the ability to receive both control information and GPS transmission requests, significantly reducing power consumption.
