Abstract

A method and system for automatically setting up a call in a radio telecommunications network. The system includes a first mobile switching center (MSC) servicing and controlling an area where a originating MS is located and a home location register (HLR) associated with the first MSC. The originating MS sends data which includes the selected time and a destination number of a terminating party. Within the HLR is service logic which determines when the selected time has arrived and initiates the call. Upon determining that the originating MS is idle and available, the HLR establishes a voice channel between the first MSC and the originating MS. Additionally, the HLR establishes a voice channel between the terminating party and a second MSC if the terminating party is a mobile station. The system also records a message for delivery at the selected time to the originating party. Additionally, the terminating party may be a telephone in the Public Switched Telephone Network (PSTN).
