informPreviousNetworkEntity  IE 

This parameter is used by the VLR to ask the HLR to inform the previous network entity about the update by sending the previous network entity a Cancel Location message. It is used if Super-Charger is supported in the network and either the serving network entity has not been able to inform the previous network entity that MS has moved (i.e. if it has not sent Send Identification to the previous serving entity) or the MTRF Supported flag is set in the MAP_UPDATE LOCATION request.
