PURPOSE: A device for supplying calling information in a mobile communication system is provided to inform a called terminal unregistered in a CNIP(Calling Number Identification Presentation) service of incomplete calling information as a text message or a voice message, thereby promoting a restart of an incomplete call. CONSTITUTION: A calling terminal(32) and a called terminal(50) basically perform voice and data communication, and exchange various information through paging and signaling channels. The called terminal(50) is not registered in a CNIP service. A calling base station(34) and a called base station(48) have cells in corresponding regions, and wirelessly communicate with terminals located within the regions of the cells. A calling BSC(36) and a called BSC(46) relay communication between the base stations(34,48) and MSCs(38,42). The calling MSC(38) and the called MSC(42) transmit messages received from VLRs(40,44) or an HLR(52) to the BSCs(36,46), and transmit messages received from the BSCs(36,46) to the VLRs(40,44) or the HLR(52). The MSCs(38,42) relay communication between CDMA subscribers and wire subscribers.
