Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a connection system between an originating subscriber and a voice message storage device in a self-service mobile phone equipped with a transfer function.

[Background of the invention]

The connection method to the conventional voice message storage device is 5E79.
-9ar audio storage service concept” and 5E82-54r
After connecting the calling subscriber and the voice message storage device as described in the ``Voice Storage Service Method'', the calling subscriber was made to dial a number such as the incapacitated person's telephone number, security guard, and ID number. However, in the conventional system, if the originating subscriber is a rotary dial telephone, even if the originating subscriber dials after connecting the originating subscriber and the voice message storage device, a direct current pulse is passed through the exchange network as a dial pulse transmission means. Therefore, it has not been possible to provide a connection service to a voice message storage device to a calling subscriber of a rotary dial telephone (particularly in the case of a time division switch). When a call is forwarded to a voice message storage device using forwarding function, it saves the trouble of having the calling subscriber dial the forwarding subscriber number, and also provides a voice message storage service for rotary dial electric machine subscribers. Our goal is to provide the following.

[Summary of the invention]

The present invention adds a function to send the forwarding subscriber number to the voice message storage terminal before connecting the calling subscriber and the voice message storage M device if the forwarding destination is the voice message #/1rffx device telephone terminal. This saves the above effort.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 shows the connection system of the exchange, the so-called switching network that forms a call, URLl is the originating register that is connected to the subscriber through the switching network when the subscriber makes a call, and receives the subscriber's dial. JS is the sending register that transmits the dialed digits, I O'l' is the subscriber-to-subscriber trunk that connects subscribers through the switching network, and SRD is the central signal between !'llL+ and @. A signal distribution device, CP, that transmits and receives
U is the central processing unit of the exchange, 1\IM is the main storage unit that stores each leakage information of the central processing unit, A and B are subscriber telephones, and C is for receiving forwarded calls to which the voice message storage device is connected. A telephone terminal, VMS is a voice message storage device, Dl is a transfer destination storage unit that stores the subscriber number of the transfer destination to which the call is transferred when the subscriber is absent, unresponsive, or busy, and D2 is: This is the subscriber number storage section of the subscriber terminal to which the voice message storage device is connected.

The connection operation of the present invention is illustrated in FIG. 1, and the transition of multiple connection states is illustrated in FIG.

When the subscriber @A makes a call, the subscriber's habit of calling becomes signal distribution device S)? Passed through D to central processing unit 0PtJ - Central processing unit [(3PtJ selects an empty transmission register,
%[
Connect to register OR via route 1. A dial tone is sent to subscriber A from the calling register. Subscription@A transfers calls to the voice message storage device when the user is absent, unanswered, or busy, so the number for transfer registration and the phone connected to the voice message storage device are required. When the calling register OR receives this number, it sends the received number information to the central processing unit CPU through the signal distribution device 5) (D).The central processing unit & OPU When the information is received, the subscriber number of the voice message storage device connection terminal C is stored in the storage section corresponding to the subscriber A of the transfer destination storage section D1 of the main storage device MM.6 When the storage is completed, the central processing f; J.C.
Registration completion information is sent from the PU to the outgoing register OR through the signal distribution device rtts. Outgoing °Register o R
, sends a registration completion tone to subscriber A upon receiving the registration completion information from the central processing unit ILCPU. By hearing the registration completion tone, the subscriber learns that the registration for call forwarding is completed, and releases the sending/receiving information, thereby releasing route 1 of the switching network SW between the subscriber A and the calling register OR. .

With the above operations, the voice message storage and subscriber number of the t* device terminal C are registered as the transfer destination of the subscriber A.

Similarly, when subscriber A makes a call and hears a dial tone, subscriber A registers the subscriber terminal to which the voice message storage device is connected. Dial the subscriber number on the telephone terminal connected to the message storage device.

The CPU of the central processing unit 17Ie, which received the information through the signal distribution device [8RD, stores the voice message in the storage section corresponding to the terminal C of the voice message storage device subscriber code storage section D2 of the main storage device MM. Remember that the device is connected.

When the storage is completed, an f-recording completion tone is sent to the subscriber in the same manner as described above. When subscriber A hangs up the handset,
m operation is completed.

With the above operations, terminal C can be registered as a voice message storage device connection terminal.

Next, when subscriber B makes a call, in the same manner as described above, subscriber B and originating register OR are connected via route 1' via the switch network, and dial tone is sent from originating register OR to subscriber B. will be sent. State number 11 in FIG. 2 corresponds to this state. To call subscriber A, subscriber B dials the subscriber number of subscriber A.

When the outgoing register OR receives the subscriber number of the subscriber, it sends the received number information to the central processing unit CPU through the signal distribution device. When the central processing unit CPU receives the subscriber number of subscriber A, the central processing unit CPU stores the transfer destination storage unit D1 of the main management device MM.
The contents of the storage unit corresponding to subscriber A are read. Subscriber A
The subscriber number C of the terminal to which the voice message storage device for receiving transferred calls is connected is stored in the storage section corresponding to the terminal. The central processing unit ll-CPU obtains the subscriber number in the transfer destination storage section, and then extracts the voice message of the main grasping device MM in order to determine whether a voice message accumulating device is connected to the terminal of that subscriber number. The central processing unit C reads the subscriber number information D2 of the terminal to which the storage device is connected.
The PU releases the subscriber saver and the route 1' of the transmission register OR, selects an empty transmission register, and connects the terminal C and the transmission register O8 through route 2 on the switching network. State number 12 in FIG. 2 corresponds to this state.

In this state, the central processing unit TtCPU distributes the signal fe[
8 or so, the transfer source subscriber number is sent from the transmission register to the voice message # detection device. When the device receives this subscriber number, the voice message storage device enters the recording state.
U releases route 2 between terminal C and sending register US, connects subscriber B and the subscriber mutual trunk with route 3, and connects another terminal of the subscriber mutual trunk with terminal C via route 4. . This state is state 13 in FIG. In this state, subscriber B's voice message is recorded by the voice message storage device.

After transmitting the voice message, subscriber B hangs up the handset, thereby connecting route 3 between subscriber B and subscriber mutual trunk and route 4 between subscriber mutual trunk and terminal C.
is released. With the above operations, the voice message from subscriber B to subscriber A is stored in the voice message storage device.

〔Effect of the invention〕

As explained above, according to the present invention, when the forwarding function is applied to the voice message storage device, the calling subscriber does not need to dial the forwarding subscriber's number. do not have.
