When the voice mailbox is received by the personal communication exchange through the base station and the base station controller, the personal mobile communication exchange notifies the home location register 190 that the voice mailbox has been received. (Step 202)

The home location register 190 searches for the corresponding called party where the voice mailbox is stored and searches whether the message waiting notification function is activated (step 204).

If the message waiting notification function is activated in step 204 and the message waiting notification function is activated, the home location register 190 sets the message waiting notification flag of the called party to be available for reception (step 206).

Home location register 190 sends an acknowledgment (ACK) message to voice mailbox block 170 indicating that it has received the voice mailbox message (step 208).

The home location register 190 sends a subscriber's authorization information request message (Qulification Directive) to the home location register matching block 158 of the exchange (step 210).

Receiving the subscriber's authority information request message, the home location register matching block 158 transmits the authority information request message to the visited subscriber manager 156 (step 212).

The visited subscriber manager 156 sets the message waiting notification flag to the state where the message is received (step 214).

When the call control unit 154 informs the subscriber that the message is waiting, the call control unit 154 determines whether the subscriber state is an idle state (step 216).

If it is determined in step 216 that it is not in the idle state, it is determined whether the step 216 of determining whether the idle state has been performed at least five times (step 218).

If it is determined in step 218 that the step of determining whether the idle state is performed five or more times, the call control unit 154 finds the subscriber and transmits a control command informing that the message has been received (step 220).

If it is determined in step 216 that the subscriber state is idle, the call control unit 154 locates the subscriber and transmits a control command informing that the message has been received (step 220).

The call controller 154 sends a message to the base station controller matching block to find a subscriber (step 222).

The base station controller 130 finds the corresponding subscriber of the message through the base station 110 and sends a response message to the base station controller matching unit 152 indicating that the corresponding subscriber has been found (step 224).

After receiving the response message indicating that the subscriber has been found, the base station controller matching unit 152 transmits a message indicating that the message has been delivered to the base station controller (step 226).

The base station controller receiving the message informing that the message has been delivered sounds a message, for example, a pip-tone, indicating that the message has been delivered to the terminal through the base station.

The call controller 154 releases the resources between the base station controller 150 and sends a response message to the visited subscriber manager 156 to find the corresponding subscriber and to receive a message indicating that the message has been delivered to the terminal.

Upon receipt of the response message, the visited subscriber management unit 156 restores the message waiting notification flag to no message received (step 228).

When the subscriber, recognizing that the message has been received, approaches voice mailbox block 170 and listens to the voice message, voice mailbox block 170 sends a message waiting cancel message to home location register 190 (step 230).

The home location register 190 recovers and terminates the message waiting notification flag (step 232).

As described above, the present invention stores a voice message in a mailbox of a subscriber and transmits a signal indicating that the voice message has been stored to the subscriber's terminal to the subscriber's terminal to listen to the voice message. It is effective to provide.
