Abstract:
The Location Updating procedure occurs when a Mobile Station \User Equipment is switched on in Mobile Switching Center service area or when an idle Mobile Station moves to a new Mobile Switching Center service area or MSC. Location Update can also occur prior to a call set-up. The Location update signaling message coming from the mobile station holds useful information. We can use this information to build a data base that can contain Brand, Make and Model, Radio Support Capability (GSM 850 /900 /1800 /1900, GPRS, EDGE, UMTS), Application Support Capability (MMS, Presence, PTT…).
In this research standard SS7 protocol analyzer used to analyze the signaling messages coming from the mobile station to the GSM core network and then applied a code using C++ language to extract the required data such as International Mobile Element Identity “IMEI”, Location Area Code “LAC”, and Cell identity “Cell ID”. That information can be used to build applications that can help Mobile operator and service companies to provide new services.
