Then the telephone set A enters the area managed by the master equipment CE-3. When a call comes to the master equipment CE-1 to call the telephone set A in such a case, the master equipment CE-1 transfers the incoming call to the destination number set by the radio wave. The ID number of the telephone set A is sent together with the call. Thus, the telephone set A in telephone sets in the service area of the master equipment CE-3 receives the incoming call at the moved destination.

Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to cordless telephone systems.

(Prior art and its problems) Conventionally, in this type of cordless telephone equipment, a plurality of PAs and equipment (CE-
1, CE-2,---CE-n) and telephone stages A, B, and C connected to these existing devices by radio lines.
-.N, and communication was carried out between this telephone and the parent device by transmitting and receiving information using radio waves.

In this case, the radio waves are transmitted with a low power of only a few milliwatts, so their range is only a few tens of meters at most, and their use is limited to a narrow area. For this reason, it is useless to carry such a phone with you, and when you move to another location, you have to leave the phone behind, making the use of expensive cordless phones inefficient and inconvenient. . Originally, it is desirable for a cordless telephone device to have a mechanism in which the telephone follows the user as he or she moves around. However, the conventional device has a drawback in that such an operation cannot be performed.

On the other hand, in conventional wired systems, it is possible to receive calls at the forwarding destination using a forwarding device, but it goes without saying that in wired systems, the forwarding number must be reset at the location of the forwarding device. Ta. Therefore, when you try to go to another place or come back from another place, you have to go all the way to the transfer device to set or reset the transfer device, and in case of emergency etc. It was a nuisance. Another inconvenience is that when a call arrives at the forwarding destination, the recipient of the forwarding may feel angry at the reception of the call.

That is, the person receiving the call at the forwarding destination does not know that the call has been forwarded, and the caller answers the call without knowing that the call has been forwarded. Moreover, it is a hassle to understand the content, search for the called party, and then call the called party to the location where the transfer destination telephone is installed.

A conventional cordless telephone device, as shown in FIG. 1, consists of a telephone and a pair of parent devices (for example, CE-1 and A), and the parent device manages the identification numbers (hereinafter referred to as IDs) of the slave stations and performs calls for making and receiving calls. A wireless connection is made while checking the ID for each call. This is a billing issue and attempts to prevent connections from other phones. For this reason, even if another telephone, for example B, attempts to connect within the wireless (hereinafter omitted) service area of the parent device of CE-1, the parent device of CE-1 will not accept the connection, making it impossible to make a call, which is extremely inconvenient. there were.

By removing this restriction and changing the system sequence so that any phone can connect to any parent device, the scope of use is greatly expanded.

Since there is still the issue of billing, there is room for consideration in giving freedom indiscriminately, but this is permissible within a limited number of establishments such as companies, for example. For the first time, the flexibility of cordless telephone equipment has expanded. In this way, telephone B can leave the parent device CE-2 that it manages, go to the neighboring parent device CE-1, and make a call from that location. However, when a call is received at the parent device CE-2, which is the resident station at this point, phone B is sent to the neighboring parent device CE-2, which is far from this service area.
Since I am within the service area managed by No. 1, I cannot receive this message and make a call.

On the other hand, in conventional wired systems, it is possible to receive calls at the forwarding destination using a forwarding device, but it goes without saying that in wired systems, the forwarding number must be set and reset at the location of the forwarding device. Ta. Therefore, when you try to go to another place or come back from another place, you have to go all the way to the transfer device to perform the cent operation or reset operation of the transfer device, and in case of emergency etc. It was a nuisance. Another inconvenience is that when a call arrives at the forwarding destination, the recipient of the forwarding is confused and confused about how to receive the call.

That is, the person receiving the call at the forwarding destination does not know that the call has been forwarded, and the caller answers the call without knowing that the call has been forwarded. Moreover, it is a hassle to understand the content, search for the called party, and then call the called party to the location where the transfer destination telephone is installed.

(Purpose of the Invention) The present invention improves this inconvenience, and in order to make it possible to receive calls at a moving destination, the parent device is equipped with a forwarding device function, and the forwarding destination can be set using telephone radio waves, and incoming calls can be received at the moving destination. The present invention provides a cordless telephone device with a transfer function that enables the transfer function.

(Structure of the invention) The present invention will be explained in detail below.

FIG. 2 shows an outline of the configuration of the apparatus of the present invention.

In FIG. 2, telephone A sets a special number, e.g. 9999, to set forwarding wirelessly to the parent device CE-1 that manages telephone A, and then sets the number of the destination C, e.g. 300, to the destination to which it is going. do. The sequence of transferred cents is shown in FIG. Next, phone A is the parent device CE
Enter the area controlled by -3. At this time, when the parent device CE-1 receives a call to call telephone A, the parent device CE-1 sends a call to the destination number 300 (C
Transfer the incoming call to E-3). At this time, not only is the information transferred, but the ID number of telephone A is also sent. Repeat this step in step 7
As shown in the figure. This makes it possible to call only the telephone A among the telephones within the service area of the transferred parent device GE-3, and clearly the telephone mA can receive calls at the destination. Even if the parent device CE-3 receives a call, the ID subsequently sent is for telephone A (number 10), so it goes without saying that telephone C (ID=30) in the same area will not be called. FIG. 6 shows these transferred and received calls.

FIG. 5 shows an example of a transfer cancellation sequence in which a transfer reset signal is sent to restore the state of the transfer setting unit 10 and transfer is canceled.

The detailed operation of the apparatus of the present invention will be explained below mainly with reference to FIG.

FIG. 3 shows a parent device having a transfer function. (Wireless) Special number for setting forwarding from telephone 8, e.g. 9999
When the data is dialed, the receiving section 7 of the parent device receives it and sends a signal to the data decoding section 6. The data decoding section 6 decodes that it is a transfer cent signal and turns on the memory of the transfer setting section 10.

When this is completed, the data decoding section 6 transmits the data to the transmitting section 7 of the device a.
The telephone 8 is notified by a signal, for example, a beeping sound, that the transfer number can now be received. The operator of the telephone 8 that opens this dials a transfer number, for example 300. Upon receiving this, the data decoder 6 sends the same number 300 to the transfer number memory 11 and stores it therein. At this point, the data decoding section 6 returns a registration completion signal, for example, a beep, to the telephone 8, and the operator knows that the registration has been completed, and by putting the telephone on-hook, the registration is completed. The above operation is shown in the flowchart of FIG.

When a call arrives on the line 1 of the parent device that has the transfer function set to transfer, the incoming call detection circuit 5 detects this. On the other hand, since the transfer setting section 10 has already been set, the AND circuit 14 performs an AND operation of the signals from both units, and the transfer switch 3 is turned downward.

At the same time, the dial circuit 13 closes the loop of the calling line 2 and determines whether the calling is possible. When it is determined that line 2 is available, transfer number memory 11 continues to be transferred.
The dial circuit 13 sends out a dial signal according to the number within. Subsequently, the other party's incoming call detection circuit 15 learns that the other party has responded, and sends out its own ID signal from the transfer number memory 11, which is its own ID ROM, through the line 2. When the other party's telephone is called and answered, the signal from line 1 has already been transferred to line 2 via hybrid 12 at transfer switch 3, so that a call can be made at this point.

This is a description of how the call was received on the phone he carried at the forwarding destination.

The explanation will be given assuming that the parent device in FIG. 3 is the receiving side.

The transferred incoming call arrives at receiving line 1.

The incoming call detection circuit 5 detects the incoming call and closes the DC loop. Next, the data decoder 6 determines whether an ID signal has been sent or not, and when determining that an ID signal has not been sent, it gives its own ID and calls its own telephone 8. , Since the incoming call in this case is an incoming call that has been transferred, an ID signal has been sent, and the data decoding unit 6 assigns the received ID without sending its own ID. Call a telephone (not shown). Since the called telephone has the same ID as its own, it emits a ringing tone, and the operator hears this, receives the call, and starts talking. FIG. 6 is a flowchart showing the above operation.

The present invention makes it possible to selectively receive calls in this way, and its function is significantly different from that of conventional wired-only transfer devices.

It goes without saying that calls can be made from within the service area of the CE-3's parent device.

(Effects of the Invention) As explained above, in the present invention, the transfer destination can be set and reset wirelessly, so there is no need to go to the trouble of going to the parent device. Another advantage is that it is now possible to selectively receive calls at the destination, so calls can be received without affecting other telephones within the service area of the i1 machine. Since the ID code of the forwarded call is sent for each forwarded call, there is no need for memory to manage which telephone is currently set for forwarding in the same parent device, and at the same time, the same
It has the advantage that there is no problem even if any number of telephones are set to transfer and receive calls in the main unit.
