Information transmitted and received between The call setup message is
It comprises a protocol identifier, a call number, a message type, a facility which is another information element, a calling number, a calling subaddress, a called number and a called subaddress. In the present invention, when transferring an incoming or recorded message, the base unit 3 places a caller, that is, the caller number of the actual transfer source, in the calling subaddress or the called subaddress so as to make a call. It has become.

B. Next, an operation of the master unit according to the above-described embodiment will be described. In the following description, the operation of each unit involved in a call is the same as the operation of a normal terminal, and a description thereof will be omitted.

B-1. Answering Machine Mode Here, FIG. 4 is a flowchart for explaining the operation when the master unit is set to the answering machine. First, in step S10, it is determined whether or not a call has been received. When a call is received, in step S12, a caller number is obtained from the call setting message. The caller ID is stored in the calling telephone 5
belongs to. Next, in step S14, the telephone is automatically off-hook and the line is connected to the telephone 5 on the calling side. Then, in step S16, a response message registered in advance, such as, for example, "I'm out of the office now, please put a message." Next, in step S18, after the message input by the other party is recorded on a tape or semiconductor memory, the line is automatically disconnected in step S20, and in step S22, based on the caller number obtained in step S12. Then, the information shown in FIG. 2 is searched, and the corresponding slave unit is obtained.

Next, in step S24, it is determined whether or not there is a corresponding slave, and if there is no corresponding slave, the process is terminated as it is. On the other hand, if there is a corresponding handset, the process proceeds to step S26, and it is determined whether or not the corresponding handset is set to “answer” the answering machine notification. Here, if the corresponding child device has not set the answering machine notification to “Yes”, the process ends. On the other hand, for example, when a call is made from the other party whose caller number is “0425-11-1111”, as shown in FIG. 2, the slave unit PS1 responds, and the slave unit PS1 transmits the answering machine notification to “ To do
, The process proceeds to step S28.

In step S28, a caller number (original caller number) is entered in the subaddress of the call setting message. In the above example, “0425-11-1111” is entered as the caller number in the subaddress. Next, in step S30, the corresponding slave unit, in this case,
A call is sent to the communication network 1 for the slave unit PS1, and a step S
At 32, it is determined whether or not there is a response from the slave unit PS1.

At this time, if the slave unit PS1 is in the service area of the appropriate public base station 5, the call is received by the slave unit PS1.
The handset PS1 receives the above-mentioned call setup message, extracts the original caller number entered in the subaddress, and displays it on the display unit, as in the past. At this stage, the slave unit PS
1 user is the phone from whom, in this case,
It can be confirmed that the call is from "0425-11-1111". When the user goes off-hook, the master unit 3 proceeds to step S34, notifies that a message from the other party has been recorded, and ends the process.

On the other hand, if the call is transmitted to the slave unit PS1 but there is no response, the process proceeds to step S36, and the slave unit P1 is wirelessly transmitted.
S1 is called, and in step S38, it is determined whether or not there is a response from the slave unit PS1. At this time, if the slave unit PS1 is within the communication range of the master unit 3, the call is received by the slave unit PS1. As described above, the slave unit PS1 receives the call setup message, extracts the transfer source number entered in the sub address, and displays the transfer source number on the display unit. Therefore, before going off-hook, the user of the slave unit PS1 reads “0425-11-11”.
11 "can be confirmed. Then, when the user goes off-hook, the parent machine 3 proceeds to step S40.
Then, the fact that the message has been recorded is notified to the slave unit PS1, and the process ends.

On the other hand, even if a call is made to the slave unit PS1 via the public line 1 or a call is made wirelessly, if there is no response from the slave unit PS1, the process is terminated without any operation.

B-2. Next, FIG. 5 is a flow chart for explaining the operation when the incoming call to the master unit is directly transferred to a predetermined slave unit. First, in step S50, it is determined whether or not an incoming call has been received. When an incoming call is received, in step S52, a caller ID is obtained from the call setting message. The caller number is that of the calling telephone 5. Next, in step S54, the information shown in FIG. 2 is searched based on the caller number acquired in step S52, and the corresponding slave unit is acquired. Next, in step S56, it is determined whether or not there is a corresponding handset, and if there is no corresponding handset, since the call is to the base unit 3 itself, the process proceeds to step S58 to sound a ringer sound. In step S60, it is determined whether or not an off-hook has been performed. If not off-hook, step S5
8, S60 is repeatedly executed. When the base unit 3 is off-hook by the user, a call is made with the other party in step S62. Whichever goes on-hook, disconnects the line in step S82, and ends the process.

On the other hand, if there is a corresponding handset (PS1), the flow advances to step S64 to enter the caller number in the subaddress of the call setting message. In the above example, the sub-address contains the original caller number “042” as the original caller number.
5-11-1111 ". Next, in step S66, the slave unit PS1 is called by radio, and in step S68, it is determined whether or not there is a response from the slave unit PS1. At this time, if the slave unit PS1 is within the communication range of the master unit 3, the slave unit PS1 receives an incoming call. As described above, the slave unit PS1 receives the call setting message as described above,
The original caller number (caller number) put in the sub address is taken out and displayed on the display unit. Therefore,
Before going off-hook, the user of the slave unit PS1 reads “042
5-11-1111 ". When the user goes off-hook, the parent device 3
Proceeding to step S70, the slave unit PS1 is wirelessly connected to the partner terminal of the communication network 1. Thereby, the other party and the slave unit PS1 communicate with each other in step S72.
If either of them is on-hook, the line is disconnected in step S82, and the process is terminated.

On the other hand, if the slave unit PS1 is not within the communication range of the master unit 3, the process proceeds to step S74, where a call is transmitted to the slave unit PS1 via the communication network 1, and at step S76, the slave unit PS1 is transmitted.
It is determined whether there is a response from 1. At this time, the slave unit P
If S1 is in the service area of the appropriate public base station 5, the call is received. As described above, the handset PS1 receives the call setting message, extracts the original caller number entered in the subaddress, and displays it on the display unit. At this stage, the user of the slave unit PS1 determines “425-11-111”.
1 "can be confirmed. When the user goes off-hook, the master unit 3 proceeds to step S78 to connect the slave unit PS1 to the partner terminal via the communication network 1. As a result, the other party and the slave unit PS1 communicate with each other in step S80. If either of them is on-hook, the line is disconnected in step S82, and the process is terminated.

On the other hand, even if a call is made to the slave unit PS1 by radio or a call is made via the public line 1, if there is no response from the slave unit PS1, the line is not transferred and the line is switched in step S82. Disconnect and end the process.

As described above, according to the present embodiment, the fact that the message of the other party has been recorded by the answering machine is notified (or the message is transferred) from the master unit 3 to the predetermined slave unit PS1 or PS2, or the telephone is transferred. When calling, the caller ID of the other party is put in the sub-address of the call setting message and the above-mentioned slave unit PS1 or PS2 is called.
The slave unit PS1 or PS2 can confirm the partner before going off-hook.

In the above-described embodiment, the caller number inserted in the subaddress of the call setting message is displayed on the handset PS1 or PS2. However, the present invention is not limited to this, and it is more specific and easy. For example, a database (phonebook) including at least a caller number and a user name may be searched, and the user name may be displayed together with the caller number. Good. Alternatively, the parent device 3 may insert the user name into the subaddress of the call setting message and transmit the message to the child device PS1 or PS2. Further, in the above-described embodiment, the cordless telephone has been described, but the present invention is not limited to this. In other words, the present invention can be implemented as long as a system in which a normal fixed telephone has a transfer function and can transfer to another terminal (wireless or wired).
