Abstract

A wireless network is disclosed that provides repeat dialing to called parties that are powered off. The wireless network includes an originating MSC system, a Home Location Register (HLR) system for a called party, and a serving MSC system that serves the called party. Responsive to identifying that the called party is powered off, the calling party transmits a repeat dialing instruction to the originating MSC system. The originating MSC system then transmits a repeat dialing indicator to the HLR system for the called party. The HLR system for the called party identifies when the called party powers on. When the called party does power on, the HLR system transmits an instruction to the serving MSC system to attempt to set up a call between the called party and the calling party.
