Abstract

PURPOSE:To receive an incoming call at a remote place without being confused, by enabling individual telephone sets to be called selectively in another service area. CONSTITUTION:In a case a telephone set A is positioned in the service area of the master device l7a of a telephone set B, the caller of the master device 17 of the telephone set A sets a switch 10 at an outgoing side, and performs a dial operation for the master device l7a of the service area where the telephone set A is positioned. An incoming side recognizes the incoming call by an incoming/response detection circuit 3, and responds from an incoming response circuit 4. The master device 17 on the outgoing side selects its own ID containing part 9, and sends its ID to lines L1 and L2 because the switch 10 is connected to the outgoing side. The master device l7a on the incoming side sends a signal to an ID sending control part 6, and sends a received ID. So that the switch 10 is connected to the incoming side, the ID is sent to a slave set call unit 11. and is sent from a transmitter/receiver unit 13 with a call signal. The telephone sets A and B identify the ID, and the telephone A rings a bell, while the telephone set B does not.

(Prior art and its problems) This type of conventional system uses a portable telephone,
It consists of a parent device that is connected to the telephone via a wireless line and to the exchange via a wired line. Furthermore, this phone and the parent device connected to it usually have a specific affiliation relationship, and the phone can communicate with other parent devices other than that specific parent device even if they are installed within a short distance where wireless communication is possible. communication was not possible even if there was a telephone other than that particular telephone in a particular combination from that particular parent device, even if there was a telephone within a short distance where wireless communication was possible. .

By removing this restriction and changing the system sequence so that any parent device can be used, the scope of use can be greatly expanded. There is still a problem with billing, so there is room for consideration in giving freedom indiscriminately, but this is permissible within a limited number of establishments, such as within a company. This marks the first time that the flexibility of cordless phones has expanded. In this way, telephone A can leave the parent device CE-A that it manages and make calls to other parent devices CE-N as well.

However, at this point, it was possible to make a call, but not to receive a call. This means, for example, that phone A is normally the parent device CE.
This is because, when a call arrives at the wired number of the parent device CE-A, such as number 10, the telephone A is called.

Therefore, phone A is connected to CE-B, which is the parent device of phone B.
You cannot receive calls even if you are within the service area. Furthermore, even if this restriction is somehow lifted so that the parent device CE-B of the telephone 81B that calls number 20 calls all telephones within the service area of the parent device CE-B, the external Even if a telephone, for example B, brought in from another country answers, the content is one that should be answered by the owner of telephone A, and this will only confuse the user.

When telephone A attempts to make a call, the parent device 17 (see FIG. 1) receives this signal and captures the lines L+ and Lx. When the line is available, the operator operates the dial on telephone A to call the number 200, and the master device 17 receives this signal and operates the dial circuit 2 to call the number 200. On the other hand, the parent device 17a on the receiving side also has the same block configuration as shown in Figure 1, and the device (No. 200) receives this signal and detects the incoming call (circuit 3), which closes the DC loop and detects the incoming call. The incoming call response circuit 4 responds to the sending side. Upon receiving this response, the calling side knows that the call has arrived through the incoming call/response detection circuit 3, and based on this information, the ID sending control unit 6 uses its own ID.
D storage section 9 is selected and an attempt is made to send the ID number to line 1, but since switch 10 is not on the calling side, the self ID is not sent. The parent device 17a on the receiving side issues an incoming call response, but since no ID signal is sent, it uses its own ID (
20) and call telephone B. Knowing that telephone aB has its own ID (number 20), a call is made and a conversation begins. The flow of these operations is shown in FIG.

If telephone A is known to be within the service area of telephone B's parent device 17a, telephone A's parent device 17a
The caller turns the switch 10 to the calling side and dials the number 200 to the parent device 17a in the service area where telephone A is located. As in the previous case, the receiving side of the parent device 17a numbered 200 detects the incoming call through the incoming call/response detection circuit 3, and responds from the incoming call response circuit 4 to the parent device ff 17 number 100 that the call has arrived. Having received this response, the parent device 17 on the originating side selects its own ID storage section 9, and since the switch 10 has been previously set to the originating side, it sends this ID (No. 10) to the lines L + and L z. Receiving side master device 17a which received this ID recognizes that the ID signal has been sent through signal decoding section 5, and temporarily stores this ID in reception ID register 7.

At the same time, a signal is sent to the ID sending TA control section 6 to send out the received ID (No. 10). Since the switch 10 is on the receiving side, this ID is sent to the handset calling unit 11 and sent from the transmitting/receiving unit 13 together with the calling signal.

Telephones A and B, which received this calling signal, identify the ID and learn that the identification number is number 10 for telephone A, so telephone A rings the bell and telephone B does not ring the bell. The recipient who hears the ringing of the bell establishes a conversation with the caller who is within the communication area of the parent device 17 of telephone A. The flow of these operations is shown in FIG.

The above describes an example in which a call is made from the parent device 17, but
A similar purpose can also be achieved by, for example, dialing a telephone number from the calling telephone and then inputting the ID number of the called telephone from a dial button.
