Patent ID: 8768301

Claim:
In a telecommunications system including at least one macro base station and at least one micro base station, each for wirelessly communicating with mobile terminals, a method of identifying movement of a particular micro base station from an expected location comprising: identifying a first communication of a given mobile terminal through the particular micro base station at a first point in time; identifying a first location relating to the first communication; identifying a second communication of the given mobile terminal through a first macro base station at a second point in time; identifying a second location relating to the second communication; performing a velocity check for the given mobile terminal between the first point in time and the second point in time using the first and second locations, wherein the velocity check includes calculating a speed or velocity result for the given mobile terminal from a distance between the particular micro base station and the first macro base station, determined using the first location and the second location, and a time period between the first and second points in time; comparing the calculated speed or velocity result with a speed or velocity threshold; and using a result of the velocity check relating to the given mobile terminal to determine whether the particular micro base station is located at the expected location, wherein, when the particular micro base station is not located at the expected location, the particular micro base station is determined as being at an unauthorized location.
