I was recently searching for my thesis a information in which way it is possible to get MS (Mobile Station) location in GSM Network. Below i will present an AnyTime Interrogation (ATI) message, which is transmitted by Service Control Point (SCP) to HLR (Home Location Reqister) for requesting MS location information. After that HLR return a query to appropriate MSC to perform VLR look-up.
