Abstract

See full text

In connection with cellular telephones, the divergent call treatment technique of the present invention is used to particular advantage. A list of accepted callers is maintained by a service supplier. When a call comes in, a determination is made as to whether the caller is an 'accepted' caller. If so, the call is forwarded to the cellular telephone. Otherwise, the caller is offered the option to pay for the call. A willingness on the part of the caller to pay for the call is indicated by a signal from the caller, such as pressing a key on a DTMF pad. In response to such a signal, the call is forwarded to the cellular telephone. In the absence of such a signal, the call is disconnected or diverted.
