Abstract
Abstract An apparatus and method, in a telecommunications network having a first and a second system, for activating and deactivating call forwarding from a dual mode subscriber station's number in the second system to the subscriber station's number in the first system. A first message is transmitted upon initiation of communication between the subscriber station and the first system. If it is determined that a data field in the first message is in the first state, call forwarding from the subscriber number of the second system to the subscriber number of the first system is activated. If the data field is in a second state, call forwarding from the subscriber number of the second system to the subscriber number of the first system is not activated. An indication of at least one type of selected subsequent event, upon which the user of the subscriber station desires to deactivate the call forwarding may also be included in the first message. If the selected event occurs, the call forwarding will be deactivated. The occurrence of the selected event may be signaled to the first system by the subscriber station in a second message.
