Abstract
In order to to enable an operator to control the subscriber's long distance carrier usage in a telecommunications network, a new subscriber-specific parameter, a locking parameter, is added to the subscriber data by the operator, in addition to a preferred long distance carrier access code. The locking parameter defines whether said subscriber is allowed to select the long distance carrier for the call or not. The locking parameter is checked each time the subscriber dials the long distance carrier access code during an originating call setup. In an embodiment of the invention, if the locking parameter indicates the subscriber is not allowed to select the long distance carrier, the call setup will be always terminated, preferably after making an announcement for informing the subscriber of the cause of the termination.
