Abstract

A method of performing a service in a mobile communication intelligent network is disclosed. The method of performing the service includes storing an identification of audio service subscribers and an identification of anticipated originating subscribers in a service control point of the network. When an originating mobile station requests a call and a terminating mobile station responds to the call, an audio service is requested through a terminating mobile switching center. In response to the request, the identification of the originating mobile station stored in the service control point and an announcement request signal are sent to an intelligent peripheral associated with the terminating mobile terminal, and the terminating mobile switching center is connected with the intelligent peripheral. The identification of the originating mobile station is thus audibly announced from said intelligent peripheral to the terminating mobile station.
