Abstract
Detection of a fraudulent remote unit (113) in a communication system (100) occurs by external fraud detection equipment (103) located external to, and in proximity to a base site (101). External fraud detection equipment (103) communicates with base site (101) via an uplink communication signal (105) and utilizes fraud detection methods not utilized by internal fraud detection equipment (111) to identify the remote unit (113) as being fraudulent. Once the remote unit (113) is identified by the external fraud detection equipment (103) as being fraudulent, the external fraud detection equipment (103) places an origination order to the base site (101) and supplies identification information on the fraudulent remote unit (113). Infrastructure equipment (109) utilizes information supplied to it by the external fraud detection equipment (103) and disconnects the fraudulent remote unit (113).
