Abstract

PURPOSE:To easily carry out rejection register of an incoming call and to reject incoming of following calls even at the time when a subscriber whose call should be rejected telephones in his destination by providing an incoming rejection register key and operating this key on the way of speaking to register incoming rejection of the telephone number of the opposite party of speaking. CONSTITUTION:When an incoming rejection register key 11 is depressed on the way of speaking after a call is established, the telephone number of the opposite party is recognized and is registered in an incoming rejection number register memory 4 and is displayed on a display device 9. When an incoming request comes from an ISDN basic interface 12 and set-up information is received, the processing to extract the telephone number of the opposite party is performed, and it is checked whether this telephone number is registered in the incoming rejection number register memory 4 or not, and incoming is rejected when it is registered there. Since the incoming rejection register key 11 is only operated to register the telephone number of the opposite party of speaking as the incoming rejection telephone number, incoming rejection is easily registered, and following incoming requests are rejected, though the subscriber whose call should be rejected telephones in his destination.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to telephones, and more particularly to telephones having an ISDN basic interface.

[Prior art] Conventionally, registration of call rejection telephone numbers has been carried out on telephones used in digital private branch exchange networks and LANs (local area networks), and there are two main types: .

(1) Password registration method - A method in which a unique password is registered in the telephone, and only incoming calls with matching passwords are permitted to receive calls.

(2) Telephone number registration method - A method in which telephone numbers for which incoming calls are to be rejected are registered in advance, and all incoming calls to registered telephone numbers are rejected.

[Problems to be Solved by the Invention] Among the conventional call rejection telephone number registration methods described above, the telephone number registration method has the following drawbacks.

The caller who wants to block incoming calls must find out the phone number that is mainly used and register by entering the number.
It's very troublesome. Additionally, if the caller calls from outside and requests a call, this phone number is different from the call rejection phone number registered for this caller, so the call will not be rejected, and the phone number will not be rejected. There is the inconvenience of having to look up the information and add the number registration.

[Means for Solving the Problems] A telephone with a call rejection function according to the present invention has a key for registering call rejection, a memory for registering a call rejection number, a display unit, and an incoming call request from an ISDN basic interface. If the call rejection registration key is pressed while a call is established and a call is in progress, the caller's phone number is recognized and the call is made.
The telephone number is registered in the call rejection number registration memory and displayed on the display, and when there is an incoming call request from the ISDN basic interface and setup information is received, the process of extracting the other party's telephone number is performed, and the telephone number is The control means checks whether the number is registered in the incoming call rejection number registration memory, and if the number is registered, the incoming call is rejected.

[Function] Just by operating the call rejection registration key, the caller's phone number is registered for incoming call rejection, so it is extremely easy to register for incoming call rejection, and even when the person you want to reject calls from outside the home. From the next call request, you can reject the call.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a telephone with an incoming call rejection function of the present invention, and FIG. 2 is a flowchart illustrating the operation of this embodiment.

The telephone of this embodiment has an ISDN basic interface 12, a physical layer control section 6, and a data link layer control section 7.
, the network layer control section 5, the audio control section 3, the squirrel 1-RAM 4 connected to the DC power supply 13, the display control section 8, the display 9, the incoming call rejection registration key 11, and the key control unit 10, microprocessor 1, and handset 2
It is composed of. And the physical layer control unit 6 is an ISD
It is connected to the N basic interface 12, as well as to the voice control section 3 and data link layer control section 7. Also, a physical layer control section 6, a data link layer control section 7, a network layer control section 5, an audio control section 3, and a list RAM 4.
, the display control section 8 and the key control section 10 are connected to the microprocessor 1 via one signal line, and each exchanges control signals and data with the microprocessor 1. Furthermore, the voice control section 3 is connected to the handset 2 and controls the transmission and reception of call signals, the display control section 8 is connected to the display 9, and the key control section 10 is connected to the contacts of the call rejection registration key 11. has been done.

Next, the operation of this embodiment will be explained with reference to FIG.

An incoming call request is received by this telephone via the I SDN basic interface 12, a call is established, and a call is made from the physical layer control section 6 through the voice control section 3 using the handset 2 as a man-machine interface. If the user wishes to reject incoming calls from this calling party from the next time onwards, the user presses the incoming call rejection registration key 11. The key control unit 10 recognizes this and passes the information to the microprocessor 1. microprocessor 1
The network layer controller 5 recognizes the calling party telephone number that has passed through the physical layer controller 6 and the data link layer controller 7, and stores it in the list RAM 4 as a call rejection number. When this registration is completed, the microprocessor 1 displays the telephone number on the display 9 through the display control section 8. This display is confirmed by the called party.

After this, when a calling party requests an incoming call via the ISDN basic interface 12 (step 21), the setup information sent from the calling party is received (step 22), and the calling party's telephone number is entered from there. Extract (step 23). The list of incoming call rejection telephone numbers registered in the list RAM 4 is searched (step 24), and the extracted calling party telephone number is compared with the registered call rejection telephone numbers (step 25). If the numbers do not match, the phone will ring (step 26) and calls will be allowed from phones that are not blocked (step 27).
, the called party takes the handset 2 off-hook and enters into a talking state (step 30).

At this time, the receiving party determines whether or not this incoming phone number will be rejected from the next incoming call (step 28).
, if the incoming call is to be rejected, it is registered in the list RAM 4 (step 29). In step 25, if it is found that the calling party's telephone number is registered in the incoming call rejection telephone number list, the incoming call from the calling party is rejected and the process immediately ends.

[Effects of the Invention] As explained above, the present invention provides a key for registering call rejection, and by operating the key during a call, the telephone number of the other party is registered for call rejection, thereby simplifying call rejection registration. Moreover, even if a person who wants to reject a call calls from outside the home, the user can reject the call from the next call request.
