Abstract
An invalid mobile telephone call made within the service area of a vendor monitored by a vendor computer is detected by RF fingerprinting or the like results in transmission of a kill-call command over a TCP/IP network to a kill-call server that is interfaced with a mobile service center through a data link interface. The kill-call server determines whether the kill-call command is valid and, if so, then it transmits a message tear down request over the data link interface to an executive cellular processor which, if the kill-call capability is active, conveys a call termination message to the associated administrative call processing database node to effect the call termination.
