A method and apparatus for a handover of a communication signal ( ) associated with a mobile communication unit ( ) between a Generic C-based wireless communication system ( ) and a MSC-based wireless communication system ( ), is disclosed. The handover method includes establishing a plurality of trunks ( ) between a landline switch ( ) and a MSC ( ). The method also includes configuring a landline number routing table ( ) and a landline trunk group table ( ) in the landline switch ( ), a mobile trunk group table ( ) in the MSC ( ), and establishing a message translation table ( ) in the computing platform ( ), such that one of the plurality of trunks and an associated signaling path to the computing platform ( ) are always selected when the handover is required.

Method and apparatus for completing a handover between wireless communication systems

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).
