Thx for your kindly reply,
The next neighbourcells on sector base is usually the same BTS. That s why it has the same Coordinates as the servingcell. I obtained the Observation Reports from Nsn in order to find out the relevant Parameters for Lokalization on GSm. There is only the neighbor cells and their signallevel, its usage is not suitable?! So, my question, are there any other Parameters to use in order to trangulate the Localization of Gsm or Umts.
