To get the location information you could use MAP signaling depending on what you want to do, the call would be MAP-PROVIDE-SUBSCRIBER-Info . Could also be that your carrier provide some other interface for location based services. I guess you want to be able to detect if a phone is active in the network or not before setting up call to it?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>To work with MAP you need SCCP, TCAP and MAP protocol layers on top of libss7, I don’t know of any open source implementation of them.
