Further, A, ~A N + B 1 ~ BN are mobile terminals, and as shown in the figure, they are divided into groups A, B, . . . , respectively.

Calls between mobile terminals and between mobile terminals and general subscribers are
This can be done by controlling the network 4 by the central controller 9 using means already known as the car telephone system, but the mobile terminals are divided into groups as described above, and key numbers are assigned to each group. The storage device 7, such as a tape recorder, has a storage area corresponding to the key number.

For example, when mobile terminal A1 of group A registers information, it dials the key number of group A and a number indicating a registration request as a special number.

Note that, as is known as a car telephone system, when a call is made from a mobile terminal, the mobile terminal number is automatically sent.

At the base station, the mobile terminal A1 is connected to the dial receiver 6 via the antenna 1, the transmitter/receiver 2, the trunk 3, and the network 4.
The dial information is received from , and transferred to the central control unit 9 upon completion of reception and reception, and the central control unit 9 captures the free space in the storage device 7 using the key number and the number indicating the registration request, and uses this free space. The address and mobile terminal number are stored in A of memory 10.
It writes in the group corresponding area, controls the talkie trunk 8, and sends out a 1/- key such as "Please record a message" to the mobile terminal A1.

Note that it is also possible to send a signal tone to notify the mobile terminal A1 that it is possible to start recording.

If the storage device 7 is an analog storage device such as a tape recorder, the voice information of the mobile terminal A1 is stored in the central control device 9.
is written to the area of the storage device 7 captured by.

This registration operation ends when the mobile terminal A1 goes on-hook or when a certain period of time elapses.

When mobile terminal A2 reads this stored information, it dials the key number of group A and a number indicating a continuation request.

At the base station, the dial receiver 6 receives this dial information and transfers it to the central controller 9, and the central controller 9 refers to the memory 10 based on the key number and stores the memory device 7 corresponding to the key number of group A. The area address is read out, and the storage device 7 is accessed using this address information to read out the stored information and sent to the mobile terminal A2 via the network 4, trunk 3, transceiver section 2, and antenna 1.

Key numbers are assigned to groups, and if it is necessary to prevent the sending of stored information to mobile terminals in other groups,
For example, if each group belongs to a different company,
The mobile terminal number corresponding to each group is stored in Mechiri 10, and by referring to this, it is possible to identify whether the mobile terminal is in the own group or in another group. Terminal read requests can be prohibited.

FIG. 2 is an explanatory diagram of the contents of the memory 10, which stores mobile terminal numbers, storage area addresses of the storage device 7, and registered mobile terminal numbers in correspondence with group numbers, and stores, for example, mobile terminal A1.
When mobile terminal B1 of group B dials the key number of group A and a number indicating a read request for the information registered by
The central control unit 9 searches the memory 10 using the number of the mobile terminal B1 automatically sent from the mobile terminal B1, and identifies whether or not it matches the mobile terminal number of group A. If it does not match, the number is sent by talkie. A read request disapproval notification or a notification using a busy tone is performed.

Therefore, confidentiality between groups can be maintained.

Various means can be used to erase the information registered in the storage device 7, but for example, the information can be erased only in the case of an erase request from a mobile terminal that has made a registration request and stored the information.

In that case, when the key number and the number indicating the erasure request are dialed, the central control unit 9 uses the key number and the automatically sent mobile terminal number to select the area of the group corresponding to the key number in the memory 10. Read the registered mobile terminal number from and check it,
If they match, the address of the storage device is read out, the contents of that address in the storage device 7 are erased, and the contents of the memory 1 are erased.
The address information and registered mobile terminal number information of the storage device 0 are deleted.

In the above-mentioned embodiment, voice information is registered and read out using a common storage area for groups, but by associating dial numbers and information contents in advance at the base station, mobile terminal At the time of registration, by dialing the key number, the number indicating the registration request, and the number indicating the information content, the number indicating the information content or the information content is stored in the storage device 7.
