A method of processing toll payments for a motorist having a wireless
communications device and a billing account, via a wireless
communications network. The method includes sensing that the motorist is
within range of a base station for a toll plaza having a given toll that
is to be paid by the motorist; determining via a mobile switching center
whether the motorist has activated a wireless toll payment service
associated with the communication device; evaluating via the mobile
switching center whether the subscriber has pre-selected a combined
billing option for the account, where it has been determined that the
service has been activated by the subscriber; sending a charge
transaction from the mobile switching center to a toll payment system,
where the motorist has not selected the combined billing option, the
charge transaction indicating that the toll has not been paid by the
motorist; and generating a billing record for the motorist at the mobile
switching center and sending a non-charge transaction from the mobile
switching center to a toll payment system, where the motorist has
selected the combined billing option, the non-charge transaction
indicating that the toll has been billed to the motorist by his/her
wireless service provider.
