Cellular mobile telephone subscribers in the public telephone network
If the log-in process via the base transceiver station (BTS) , the base station controller (BSC) and the particular mobile service switching center (MSC) with verification of access authorization through the authentication center (AC) has been completed, the cellular mobile telephone subscriber can dial the number of the desired party to be called by entering a telephone number.
If the cellular mobile telephone subscriber is authorized, the MSC feeds the call into the public telephone network through the public switched telephone network (PSTN) .
