Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone connected to a telephone network, and particularly to a telephone number stored in the telephone itself to automatically make a call to a telephone exchange at regular intervals for a certain period of time to obtain a busy tone from the exchange. (Hereinafter abbreviated as BT) and ring bag tone (hereinafter abbreviated as RBT)
The present invention relates to a telephone with a camp-on function, which determines whether a called party is in an empty state or not and calls the calling party only when the called party is idle.

[0002]

2. Description of the Related Art Conventionally, this type of camp-on function is generally realized as a function of an exchange.

[0003]

The conventional camp-on function is implemented in the private network but not in the public network because of the function provided in the exchange, and in general, it is accommodated in the public network. The disadvantage is that subscribers cannot get the camp-on service. In addition, if the number of subscribers using the camp-on service on the private network increases, or if the frequency of use of the camp-on service by one subscriber increases, the called number storage device (memory) on the exchange side
There is also a drawback in that it is necessary to add a new one, and because of this additional processing, the replacement function is temporarily stopped and the facility cost is increased.

[0004]

In order to solve the above-mentioned problems, the present invention comprises the following means. That is, a means for registering a camp-on connection, a means for accumulating a called party number, a means for taking out a called party number accumulated at a constant interval for a fixed period, in the telephone itself connected to the telephone network. Means for automatically making an outgoing connection to the exchange at intervals, means for receiving a BT or RBT from the exchange and determining the callee's idle state, and means for immediately canceling the outgoing connection when the called party is busy , Called when the called party is idle, means to notify the caller of the called party's availability with a special tone, and means to clear the called party number accumulated after a certain period of time or when the called party is called If a person responds first, a means for notifying that the camp-on connection is established is provided. Here, when the called party is busy, not only normal busy but also blocking of the line and common equipment is included.

[0005]

In the present invention, the called party number designated by the caller with the various keys of the registration instruction section is stored in the number storage section. Then, the clock management unit reads this called party number at regular intervals, and if the called party number is registered, issues an instruction to the connection control unit to make an outgoing connection to the exchange.

Further, the tone information from the exchange is received by the tone receiving section, and it is determined whether the tone is BT or RBT. B
When T is received, the connected line is disconnected and the outgoing connection is terminated, but when RBT is received, the tone generator is activated. The tone generator immediately calls the caller with a talkie or a special tone, and at the same time sends a talkie indicating that the call is on to the called party. These talky or special tones are sent until the caller answers.
Therefore, the called party can hear the talkie indicating the camp-on connection if the called party answers first, and can immediately talk to the calling party if the calling party answers first. The subsequent operation is the same as the normal outgoing connection operation. The above operation is repeated until the connection with the called party is completed (RBT is received from the exchange), or until a certain period of time elapses. Therefore, once the caller has registered the camp-on connection, he or she simply waits for a call by the camp-on connection and does not need to perform any operation.

[0007]

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a telephone with a camp-on function according to the present invention. In the same figure, the call originator connects the handset 11 off-hook (OFF HO).
After the OK), the called number is dialed by using the ten-key 2 of the registration instructing section 1. The dialed number (called number) is stored in the first memory of the number accumulating section 6, that is, the dial numeral temporary accumulating memory 7. Accumulated temporarily. Other operations are similar to those of the normal outgoing connection.

[0008] Here, when the connection to the called party cannot be executed due to a busy or other reason and a BT connection is made, the calling party can register the camp-on connection. This registration is completed by simply pressing the camp-on registration key 3 after the handset 11 is off-hook, but the telephone operates as follows. When the camp-on registration key 3 is pressed, the number storage unit 6 is activated, and the number storage unit 6 checks the contents of the camp-on memory 8 as the second memory. At this time,
If nothing is registered in the camp-on memory 8, the contents of the dial number temporary storage memory 7 are copied to the camp-on memory 8, and at the same time, the contents of the camp-on memory 8 are displayed and registered on the display panel 5. Notify the caller of completion.

At the same time, the clock management unit 12 is activated.
The clock management unit 12 starts timing for a certain period from the time when it is activated, and the camp-on connection operation is performed only during this period. After this certain period, the clock management unit 12 activates the number storage unit 6. Then, the contents of the camp-on memory 8 are cleared, and the camp-on process ends. On the other hand, when the data is registered in the camp-on memory 8, the camp-on service is being executed, the registration is not performed this time, and only the contents of the camp-on memory 8 are displayed on the display panel 5. The caller can see from this display that the registration has been canceled.

If it is desired to delete the registered camp-on, the camp-on delete key 4 is pressed. When the camp-on erase key 4 is pressed, the number storage unit 6 clears the contents of the camp-on memory 8 and stops the timing of the clock management unit 12 for a certain period. Therefore, if the camp-on registration key 3 is pressed again, the camp-on that was previously canceled can be registered. The telephone registration operation is as described above.

Next, the camp-on connection operation will be described. The clock management unit 12 reads the contents of the camp-on memory 8 of the number storage unit 6 at regular time intervals during the connection operation,
Only when the called party number is registered in the camp-on memory 8, the number sending section 15 is activated to deliver the called party number. The number sending unit 15 activates the connection control unit 13, the connection control unit 13 makes a normal outgoing connection to the exchange, and the number sending unit 15 sends the called party number to the exchange. After that, the switch 14 of the connection control unit 13 is switched and the call line 17 to the exchange is pulled into the tone receiving unit 16, and the B from the exchange is switched.
Wait for T or RBT.

When the BT is received from the exchange, the tone receiving unit 16 activates the connection control unit 13 to activate the call line 1 to the exchange.
Break the loop of 7 and terminate the outgoing connection. As described above, the clock management unit 12 receives the RBT from the exchange,
The outgoing connection to the called party of the camp-on memory 8 of the number accumulating unit 6 is repeated at a constant time interval until the number accumulating unit 6 instructs to cancel the timing process for a certain period.

On the other hand, when the RBT is received from the exchange, the tone receiving unit 16 activates the tone generating unit 10 and the speaker 9 calls the caller (or a special tone).
At the same time that a talkie is sent to the exchange (callee) to notify that the camp-on connection has been made. At the same time, the connection control unit 13 is activated and the switch 14 is controlled to generate a tone.
Set the route to send the talkie from copy 0 to the exchange.
The tone receiving unit 16 also activates the number storage unit 6 and clears the contents of the camp-on memory 8. Number storage unit 6
Activates the clock management unit 12 to stop the timing processing for a certain period.

When the called party answers, the tone generator 10
However, when the caller responds, the connection control unit 13 activates the tone generation unit 10 and simultaneously stops the transmission of the talkie (or special tone) transmitted to the caller and the called party. , The switch 14 is controlled to disconnect the tone generator 10. After that, the communication between the caller and the called party is performed in the same manner as the normal outgoing connection.

[0015]

As is apparent from the above description, according to the present invention, the camp-on function is provided in the telephone itself.
Camp-on service can also be provided to subscribers who are accommodated in a telephone network (exchange) that does not have a camp-on function. Furthermore, in an exchange that has a camp-on function, such as a private network, the camp-on function can be deleted from this exchange, so that the exchange can be spared and new services can be provided, and the number of camp-on subscribers increases. Even if the system is not stopped, there are practically excellent effects.
