ABSTRACT:
A wireless network is disclosed that provides repeat dialing to busy called parties. The wireless network includes an originating MSC system that serves a calling party, and a terminating MSC system that serves a called party. The calling party initiates a call to the called party through the originating MSC system, and the terminating MSC system determines that the called party is busy on another call. The originating MSC system then receives a repeat dialing instruction from the calling party and transmits a repeat dialing indicator to the terminating MSC system. The terminating MSC system identifies when the called party becomes available in substantially real time. When available, the terminating MSC system attempts to set up a call between the called party and the calling party.
