〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an operational procedure diagram showing a first embodiment of the present invention. In FIG. 1, a wireless telephone 11. Base station 12. Switchboard 13. and the connection status of the calling party 14, as well as the calling procedure (step 111), the calling procedure (step 112), and (step 113) are the same as before, and their explanation will be omitted.

The radio telephone 11 sets response refusal by operating a predetermined button, for example, and confirms this setting with at least one of a lamp display and a character display.

In a first embodiment, the base station 12 has a timer, which is activated at a predetermined time during the incoming call procedure (step 113) or when a predetermined time has elapsed since the transmission of the calling party number (step 114).

The radio telephone 11 rings the bell (step 115) according to the incoming call procedure (step 113), records the received calling party number in a predetermined storage area, and displays the number on the display (step 116). Therefore, the originator of the incoming call can be confirmed.

The base station 12 performs timed measurement (step 120) started by the incoming call.
), when sufficient time has elapsed to record the number and to confirm the caller in order to answer, the wireless telephone 1
1 (step 121) to stop the ringing of the bell (step 122), and also sends a response refusal procedure (step 1).
40), the caller is notified of the response rejection setting to the exchange 13 (
Step 150).

The caller 14 who received the response rejection notification transmits a call termination signal to the exchange 13 by off-hook operation (step 151), so the exchange 13 transmits a disconnection signal to the base station 12 (step 15).
2) and recovers (step 153), and also recovers itself (step 154).

The incoming call display in step 116 may be by displaying the calling party's number in text on the display, but may also be by lighting a specific lamp. After the bell ringing is stopped due to the response rejection notification, the latest number may be used as described above, but the oldest received number may be returned to and displayed. Of course, the calling party numbers are recorded in sequence for successive incoming calls, and by a predetermined operation, the recorded calling party numbers are called out in a predetermined order and displayed in text on the display. Deletion of recorded numbers is performed by a predetermined operation, but this is outside the scope of the present invention and will not be described here.

If there is a normal response from the wireless telephone 11 before the time limit in step 120 expires, the response is immediately notified to the exchange and the normal operation procedure can be executed, regardless of whether or not the response rejection setting is registered.

The response rejection notification in step 150 is a voice guidance saying "I am currently unavailable, so I will call you back later." is sent from the exchange 13 to prevent troublesome re-calls, but the content of the notification is based on the present invention. is outside the scope of and is not limited to.

Next, a second embodiment of the present invention will be described with reference to FIG. In FIG. 2, the same steps as in FIG. 1 are given the same numbers and their explanations will be omitted.

In this second embodiment, the wireless telephone 21 has a time limit means, and the incoming call procedure (step 113), calling party number reception (step 11)
4) and the completion of number recording (step 116), timed measurement (step 130) is started. When the predetermined time has elapsed, the wireless telephone 21 automatically notifies the response by an off-footer signal (step 131), and then notifies the end of the call by an on-hook signal within a predetermined time (step 132).
)do. That is, a pulsed off-footer signal is transmitted to the base station 22 as a response rejection signal. Wireless telephone 21
stops ringing the bell by sending an off-footer signal (step 13)
3) Do.

The base station 22 that has received the pulsed off-footer signal recognizes the response rejection and executes the response rejection procedure (step 140) described above.

When the base station 22 receives the response signal (step 131) and a predetermined period of time has elapsed, if the call termination signal has not arrived, the base station 22 can transfer the call to the exchange 23 as a normal response. In this case, the pulse width is set narrow to prevent delay in closing the communication path.

It has been explained that step 131 is automatically generated depending on the time limit (step 130), but when the wireless telephone 21 manually generates a pulse-like off-footer signal during time limit measurement, a response rejection signal can be sent to the exchange 23 without waiting for the time limit. .

Next, the response rejection procedure will be explained with reference to FIG. FIG. 3 is a procedure diagram showing an example of a response refusal procedure. When the base station notifies the exchange of a response using an off-footer signal (step 141), the exchange forms a communication path (step 14).
2) Therefore, the base station sends a voice notification of response rejection via this communication path. In order to prevent incoming calls from the same caller from occupying the recording area of the wireless telephone and to avoid an unnecessary increase in call volume, a call-back guidance is adopted. The caller's on-hook operation after hearing this guidance results in a call termination signal, and the exchange and base station are restored as shown in FIG.

When the exchange is compatible with the I5DN (Integrated Service Digital Network) and has a data channel with the base station, the response rejection procedure is such that the base station first sends a response rejection signal to the exchange via the data channel to recover. do. The exchange that receives the response rejection signal informs the caller of a response rejection notification.

Therefore, base station load and channel usage are reduced.

In Figure 1, recovery between the exchange and the base station occurs via the exchange through the caller's termination signal, but when a predetermined period of time has elapsed, the base station unilaterally sends a termination signal to the exchange. You can also send and recover.

In the example shown in FIG. 1, even if there is no response rejection setting on the wireless telephone, the base station executes the response rejection procedure when the predetermined time limit is exceeded. Therefore, the time limit when used in combination with the second example is set to a longer time, taking into consideration the normal response time.

In FIG. 2, it was illustrated and explained that the pulsed off-footer signal from the wireless telephone is used as a response rejection signal to start the response rejection procedure, but a response rejection signal different from the pulsed off-footer signal is sent to the common control radio line. The base station may initiate a response rejection procedure by predefining and transmitting/receiving.

It is convenient for the wireless telephone to record the time of call arrival along with the calling party number, and if only the number is recorded, double recording due to repeat calls is prevented. If the radio telephone can manually stop the ringing of the bell when set to refuse a response, it can record the calling party number and notify the calling party in any of the embodiments.

〔Effect of the invention〕

As explained above, according to the wireless telephone system of the present invention,
When a call is received on the radiotelephone, the radiotelephone can record and display the calling party's number, and at least one of a predetermined time and a predetermined operation can be used to notify the calling party of the incoming call. By adopting a configuration that notifies the user of a refusal of response, a wireless telephone that connects via a base station that connects to an exchange with a subscriber line that terminates a conventional telephone can call back and contact you at a later time even if the telephone cannot be answered immediately. Operational improvement effects can be obtained.
