Femtocell geo-location challenge: DSL approach as solution

Femtocell or Home eNode cell in LTE is a home base station that anticipated to be deployed in very large numbers with fully automated manner. Femtocell provides enhanced coverage for in-building cellular services. The enhanced data rates enable new multimedia services which in turn generate new revenue. However, with all the convenience such device can provide, locating the user's geographic location represents a great deal of challenge for law enforcement and operators alike. In this work we propose a simple and direct approach that does not require any changes in the network or in the femtocell standard design by exploiting the connection between the femtocell and the network operator through the DSL backhaul. Result shows the proposed approach has achieved successfully the goal of locating the geographic location of the femtocell user precisely.
