Abstract

A portable cellular phone system is provided which is capable of notifying a portable cellular phone of a presence or absence of a voice message by using a radio packet communication system.

The voice message to be fed to a user of the portable cellular phone is sent out from a telephone by a caller'"'"'s manipulation of the telephone. The voice message sent out from the telephone is transmitted through a dialup line and, when a location of the portable cellular phone has not been registered, is transferred to a voice server through a switching center. When the location of the portable cellular phone has been registered, a voice message arrival notifying signal is sent out from the voice server through the switching center and a base station to the portable cellular phone by using the radio packet communication system. The portable cellular phone notifies its user of receipt of the voice message.

Claims

1. A portable cellular phone system enabling a user of a portable cellular phone to make use of a stored-type voice message service comprising:

units to store, when connection with said portable cellular phone is unable to be made, a voice message to be fed to said portable cellular phone and to provide, when connection with said portable cellular phone is able to be made, a notification that said voice message has been stored, to said portable cellular phone.

2. The portable cellular phone system according to

claim 1

, wherein said notification that said voice message has been stored is provided to said portable cellular phone by using a radio packet communication system.

3. A portable cellular phone system enabling a user of a portable cellular phone to make use of a stored-type voice message service comprising:

a telephone set used to send out a voice message to be fed to a user of said portable cellular phone by a manipulation of a caller of said telephone set;

a dialup line used to transmit said voice message;

a switching center used to transmit, when connection with said portable cellular phone is unable to be made, said voice message fed through said dialup line to a voice message storing device and to send out, when connection with said portable cellular phone is able to be made, a voice message arrival notifying signal informing that said voice message has been stored, by reading it from said voice message storing device;

said voice message storing device used to store said voice message transmitted from said switching center and to send out said voice message arrival notifying signal;

a base station used to send out said voice message arrival notifying signal fed from said switching center to said portable cellular phone; and

said portable cellular phone used to receive said voice message arrival notifying signal and to notify said user of said portable cellular phone of receipt of said voice message arrival notifying signal.

4. The portable cellular phone system according to

claim 3

, wherein said base station is so configured as to send out said voice message arrival notifying signal fed from said switching center to said portable cellular phone by using a radio packet communication system.

5. The portable cellular phone system according to

claim 3

, wherein said voice message arrival notifying signal contains information about a caller and said portable cellular phone has a function to display said information about said caller.

6. A method for controlling a portable cellular phone system enabling a user of a portable cellular phone to make use of a stored-type voice message service comprising:

steps of storing, when connection with said portable cellular phone is unable to be made, a voice message to be fed to said portable cellular phone and of providing, when connection with said portable cellular phone is able to be made, a notification that said voice message has been stored, to said portable cellular phone.

7. A method for controlling a portable cellular phone system enabling a user of a portable cellular phone to make use of a stored-type voice message service comprising:
