Abstract

PURPOSE:To repel a repeated mischievous telephone by comparing a registration telephone number with a caller number in the reception of incoming call in the case of receiving the incoming call with a telephone set connected to a network(ISDN) having a service to inform callee number information to a callee and neglecting the incoming call when it coincides with an incoming call neglecter number. CONSTITUTION:When an ISDN telephone set receives the incoming call, an interface 2 detects the incoming call, and a control circuit 5 reads in the caller number from data sent simultaneously with the reception of the incoming call. Next, an incoming call neglecter number list is retrieved, and the caller number sent currently is compared with the incoming call neglecter number list, and the incoming call is neglected when the number coinciding with the one in the list exists. At such a case, it is possible to register the opposite telephone number of a mischievous telephone only by depressing an incoming call neglecter number registration key 7, and to neglect the incoming call of the second and after mischievous telephone from the same opposite party.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a telephone set, and relates to a telephone set connected to a network having a service for notifying caller number information to a called party, such as rsDN (integrated digital service network), for example. Regarding.

[Prior Art] Conventionally, a typical method for repelling prank calls using a telephone connected to a general public network is to first respond with a recorded voice on tape, etc., and then check to hear the other party's voice. There are methods such as answering the phone from someone else, or having the user enter their ID number and not answering unless the correct number is entered.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, in order to answer repeated prank calls and confirm the voice of the other party, the user must go close to the telephone each time. , the disadvantage is that you cannot respond to calls from acquaintances whose ID numbers you do not know.

The present invention was made to solve the above problems, and
Do not set up a special ID number (, repeatedly or once (
To provide a telephone that can effectively repel prank calls.

[Means for Solving the Problems] In order to achieve the above object, the telephone of the present invention has the following configuration. That is, in a telephone connected to a network having a service of notifying caller number information to a called party, a storage means for storing a telephone number, a registration means for registering a caller number at the time of receiving a call in the storage means, The telephone number includes a comparison means for comparing the telephone number registered in the registration means and a caller number at the time of incoming call, and a rejection means for rejecting the incoming call when the numbers match according to the comparison means.

C Effect] With the above configuration, if you want to reject an incoming call, register the caller's number at the time of the incoming call, compare the registered phone number with the caller's number at the time of the incoming call, and reject the call. If the numbers match, the call will be rejected.

[Embodiment] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

<Description of configuration (Fig. 1, Fig. 2)> Each part indicated by reference numerals 1 to 8 in Fig. 1 is l5DN.
This constitutes the telephone set connected to the network. In the figure, the telephone line from the 15DN network is connected to interface 2. Interface 2 is the l5DN network and handset 1
and mediates data signals between the IDSN network and a control circuit 5, which will be described later. The control circuit 5 analyzes the data, displays it on the display 6, outputs sound from the speaker 8, and also senses the keys 7 or reads or writes data in the memory 3. Each process of the control circuit 5 is stored in the ROM 4 as a program.

Further, the keys 7 include a call rejecting party number registration key that stores the telephone number of the party whose incoming call is to be rejected in a memory with a single touch.

FIG. 2 shows a part of the memory 3 mentioned above, which stores the telephone numbers of the parties whose incoming calls you wish to reject (represents a call rejecting party number list). Consists of call rejection number registration memory, 1
The two call rejection number registration memories have the capacity to register the maximum number of digits of the caller number sent from the network.

Description of control procedure (FIG. 3)> Next, the control procedure of the telephone in this embodiment with the above configuration will be explained.

The flowchart shown in Figure 3 compares the caller number sent via the network at the time of an incoming call with the telephone number written in the above-mentioned call rejection number list, and controls the incoming call. It is a procedure.

For the sake of brevity, only the procedure for receiving a call that is relevant to the present invention will be described here.

The control procedure shown in FIG. 3 is started when the 15DN telephone is powered on. In step S1, the 15DN telephone is in an idle state, waiting for an incoming call.

Thereafter, when there is an incoming call, the interface 2 detects the incoming call and outputs an incoming call detection signal to the control circuit 5. Based on this detection signal, the control advances from the judgment in step Sl to step S2, and the caller number is read from the data sent at the same time as the incoming call.Next, in step S3, a call rejection number list is searched, and the The result is determined in step S4.

This search process is a process in which the currently sent caller number is compared with the call rejection number list to check whether a matching number is included in the call rejection number list. As a result, if the call is found, the control proceeds to step S12 based on the determination in step S4, the incoming call is rejected, and step S1
Returns control to the idle state and waits for the next call.

However, if the list search results show that the call is from a person who is not registered in the call rejection list,
Control proceeds from step S4 to step s5. Then, in step S5, the control circuit 5 outputs a ringing tone from the speaker 8 and waits for the telephone user to take the handset 1 off-hook and respond. In this response waiting state, steps S6 and S7 are repeated, and if the caller disconnects the line before the user responds, the control advances to step Sll based on the judgment in step S6, stops dispensing, and returns to step S1. Return control. However, if the user responds, the control proceeds to step S8 to stop dispensing, and transition to a talking state in step s9 and step SIO.

In this call state, when the call ends normally, control is returned to step s1 based on the judgment of step SIO. However, if the user determines that the call is a prank call and wishes to restore the caller's number to the call rejection number list, the user presses the call rejection number registration key of key 7. When the control circuit 5 confirms that the registration key has been pressed, the control proceeds to step S13 based on the determination in step S9, and after registering the incoming call rejection number in the memory, the line is disconnected in step S14, and the process returns to step s1.

According to the above steps, if you receive a prank call, simply press the call rejection number registration key to register the phone number of the person receiving the prank call in the call rejection number list with one touch. You can also reject prank calls from the same caller for the second time or later.

In addition, in this embodiment, the caller whose phone number is registered in the call rejection number list rejects the call from the second time onwards, but it is also possible to input the data of the number of times the call is registered in the call rejection registration memory. , the incoming call may be rejected if the user registers twice (or more times).

[Effects of the Invention] As is clear from the above explanation, the present invention has the excellent effect of being able to effectively repel repeated prank calls without providing a special ID number. .
