We demonstrate the<br \/>\nusability of the solution on practical tests carried out in a live GSM network.<br \/>\nINTRODUCTION<br \/>\nIn principle two tracking methods are used. Active tracking is based on periodic questioning<br \/>\nof the network about the location of tracked devices. Conversely passive tracking methods use<br \/>\nlocation information generated during communication between a mobile phone and the GSM<br \/>\nnetwork. The advantage of active tracking is that it can track passive subscribers who are not using<br \/>\nthe mobile phone at the moment. We present the SS7Tracker &#8211; a feasible approach to mobile<br \/>\nphone localization and tracking implemented within a live GSM network. For the mobile phone<br \/>\nlocalization we use Cell-ID positioning based purely on signaling messages of the Mobile Application<br \/>\nPart (MAP) protocol from the standard SS7 protocol. This determines the main features of<br \/>\ntheSS7Tracker: It is non-intrusive to the existing signaling network equipment in the sense that it<br \/>\ndoes not demand any software or hardware changes neither in the network core elements nor in<br \/>\nthe localized mobile phones. The platform is able to localize any subscriber of the GSM network,<br \/>\nno matter if his or her mobile phone is equipped with<br \/>\nGPS or if the subscriber is passive. It provides real-time localization with only small delay caused<br \/>\nby propagation of messages in the network, and the location accuracy depends on the size of network<br \/>\ncells. The localization is ensured by queries hidden to the localized subscriber and does not<br \/>\nrequire subscriber cooperation.<\/p>\n<p>ARCHITECTURE<br \/>\nThe architecture of the platform is client-server oriented. The server side is equipped with SS7<br \/>\nsignaling board which acts as a GSM network signaling point via TDM and Ethernet card which<br \/>\nacts a GSM network signaling point via SIGTRAN (IP). The server side is connected to a live signaling<br \/>\nnetwork in order to communicate with mobile network nodes to ensure the location retrieval.<br \/>\nResults of the tracking are visualized in a client side front end application GUI or map.<br \/>\nFEATURES<br \/>\nThe following features are provided by our solution:<br \/>\n&#8211; The system supports simultaneous operation with up to 4 mobile operators (one SS7 link per<br \/>\noperator).<br \/>\n&#8211; SS7Tracker allows the end user to detect CGI of subscriber of the home network.<br \/>\n<a href=\"http:\/\/crypton-m.ua\/wp-content\/uploads\/2016\/11\/brochure_strategic_activegsm.bmp\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-68 alignleft\" src=\"http:\/\/crypton-m.ua\/wp-content\/uploads\/2016\/11\/brochure_strategic_activegsm.bmp\" alt=\"brochure_strategic_activegsm\" width=\"382\" height=\"240\" \/><\/a>Optionally, the solution can support<br \/>\nreal location detection of the roaming<br \/>\nsubscriber in any country of the world and<br \/>\nfor any serving mobile operator network.<br \/>\nSS7 Tracker solution has a possibility<br \/>\nto connect to any known type of known<br \/>\nnodes of CS Core.<br \/>\nAccuracy of MS location detection<br \/>\n&#8211; from 300 to 500 meters in urban conditions<br \/>\nand about 1500 &#8211; 5000 meters<br \/>\noutside the city.
