Radio Cell Location Identification via Mobile Node Timing Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile network operators lack detailed information about the radio coverage of competing networks, making it difficult to enhance their own network's coverage and capture roaming traffic effectively.
Innovation Solution
A telecommunications system that uses data processing to identify the location of radio-coverage cells in competing networks by analyzing communication patterns and signaling messages from mobile nodes, allowing operators to estimate the location of unknown cells based on adjacent known cells and improve coverage analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mobile network operators use traditional methods to determine cell locations (movable base transceiver station or special test telephone), then they can obtain location information, but the process is complex and requires specialized equipment
Solution Approach 1:
The patent uses existing mobile nodes (subscriber devices) to collect cell location data instead of requiring specialized test equipment. The mobile nodes act as copies or substitutes for the specialized equipment described in prior art, performing the same function of identifying cell locations through their regular communication activities with the network
Solution Approach 2:
The system leverages the mobile nodes' own positioning capabilities and communication patterns to identify cell locations. Rather than requiring external specialized equipment to probe the network, the mobile nodes themselves provide the necessary data through their normal operation, making the system self-sufficient
2Productivity
If operators analyze radio coverage of competing networks, then they can improve their own network coverage and capture roaming traffic, but they lack access to detailed information about competing networks
Solution Approach 1:
The patent introduces an intermediary data collection and processing system that captures signaling messages (such as handoff messages and location update messages) from the mobile network. This intermediary system extracts cell location information from the signaling traffic and makes it available for coverage analysis, bridging the gap between available network data and the need for competitive intelligence
Solution Approach 2:
The system uses universal mobile nodes (regular subscriber devices) that already exist in the network for multiple purposes: both for normal communication and for collecting cell location data. This eliminates the need for separate specialized equipment and allows the same network infrastructure to serve both operational and analytical functions

AI summary
A telecommunications system provides a facility for mobile nodes to communicate via one or more mobile radio networks. A data processor is provided which is operable to detect a communication from a mobile node via a first radio-coverage cell at a first time, and to detect a communication from the mobile node via a second radio-coverage cell at a second time. The data processor is then operable to determine that the difference between the second time and the first time is less than a predetermined value, and if so to identify the location of the first radio-coverage cell based on knowledge of the location of the second radio-coverage cell. In this way, communications made within a predetermined time of each other on the same mobile terminal but via different radio-coverage cells can be used to identify the location of one of those radio-coverage cells from the known location of the other of the radio-coverage cells.
