I am looking at the possibilities of LBS with a triangular measurement of the position of a handset. Therefore I need information of surrounding BTSes. I know the following:
- A handset knows the cell ID and the transmitted power of his current antenna.
- A handset detects surrounding BTSes so that he can switch between them if necessary.
- A handset knows only the channel on which the surrounding BTSes transmit and it also knows the color coding. There is a maximum of eight different colors, because the color code is three digits.
I wonder if it is possible to link the color code and the channel to a cell ID. Telecom operators have tables with cell number, address info (lon/lat as well as street) and signal strength (I have a database snapshot). Is information about the channel and the color code also included or retrievable? If not, then a triangular measurement will be quite impossible I am afraid.
Thank you for your answer.
