Abstract

Abstract A communications system permits a personal mobile telecommunications device user, such as a cellular telephone subscriber (102), to complete a connection to a calling party (101) that has attempted to reach the subscriber using the subscriber's assigned telephone number, even when the subscriber is roaming outside of his or her home area. The system includes a messaging and bridging complex (110) having an associated database (106), which receives a call placed to the subscriber. If the subscriber is out of his or her home area so that the call cannot be completed, information stored in the database is used to initiate transmission of a paging signal (from 112) to the subscriber. The connection to the calling party is held in the complex for a predetermined period after the paging signal is transmitted. The mobile telephone user (102), upon receiving the paging signal, may initiate a call from their personal mobile telecommunications device to the messaging and bridging complex, which bridges the subscriber and the calling party together. The system can also include interactive voice response equipment for advising the calling party that the call cannot be completed and that a paging signal is being transmitted. The calling party may also be offered other options, including an opportunity to use a voice mailbox or other facility to leave a message in the event that the call cannot be completed.
