ABSTRACT:
A limit is placed on charges to be incurred on a telecommunications call. Normally, this limit is specified by the caller. The telecommunications network maintains a running tally of the charges being incurred and notifies the caller when the charges approach the limit. At that time, the caller may specify a new limit, simply disconnect, or be automatically disconnected when the limit is reached. Advantageously, callers can limit the charges on a particular call without having to be aware of the exact charging parameters for that call.
