Abstract

PURPOSE:To reject an incoming call when no call number is informed by providing a rejection means rejecting an incoming call when no call number exists in received call information. CONSTITUTION:When a call setting is received from a communication network 1 and whether or not the setting information includes a call number is discriminated and when the call number exists, a controller 22 returns a reply to the communication network 1 to apply usual communication with the caller. When no call number is included, the controller 22 sends release end to the communication network 1.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an incoming call rejection method, for example, a method that uses a call control procedure of a communication network (ISDN) that can notify a called terminal of a calling number. This relates to a call rejection method.

[Prior Art] Conventional call rejection methods utilize a calling number, a password, etc. notified from a communication network.

[Problems to be Solved by the Invention] However, in the conventional example, when the communication network can notify the calling terminal to the called terminal, there are cases where the calling party makes the call without notifying the terminal number. It wasn't taken into consideration.

The present invention was made to solve the above problems, and
The purpose of the present invention is to provide an incoming call rejection method that can reject incoming calls when there is no calling number from the caller.

[Means for Solving the Problems] In order to achieve the above object, the incoming call rejection method of the present invention is as follows:
It has the following configuration. That is, in a call rejection method for a terminal connected to a communication network that can notify the called terminal of the calling number, there is a receiving means for receiving call information from the calling party, and a receiving means for receiving the call information received by the receiving means. If there is no number, a rejection means is provided to reject the incoming call.

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

FIG. 1 is a diagram for explaining an embodiment according to the present invention,
1 is a communication network that can notify the calling party of the calling party; 2.3.
. . . is each terminal connected to the network.

FIG. 2 shows the call control procedure for the calling side, the communication network, and the called side when the above-mentioned communication network is assumed to be 15DN.

The incoming call rejection method in this embodiment will be explained below with reference to the drawings.

Now, assume that terminal 2 makes a call to terminal 3. At this time, it is assumed that terminal 2, which is the calling side, sets up a call to the communication network without including the calling number, as shown in step 11. For this call setup, the communication network performs step 12.
In step 13, the call setting acceptance is returned to the calling terminal 2, and in step 13, the call setting is sent to the called terminal 3.

On the other hand, when terminal 3 looks at the contents of the call setup from the communication network and finds that the calling number is not included, it performs step 14.
A release completion message is returned to the communication network so that the incoming call is not accepted.

Upon receiving this release completion, the communication network sends a release to the calling party in step 15, and the calling party returns release completion to the communication network in step 16, thereby completing the call control procedure in this case.

Next, the configuration of the terminal in this embodiment will be described below.

FIG. 3 is a block diagram of the terminal in this embodiment,
It is possible to handle voice/data. In the figure, 21 is a communication line connecting the communication network 1 and the terminal, 22 is a control device that controls the operation of the terminal, 23 is a communication interface that communicates with the communication network 1 via the communication line 21, and 24 is the operation of the control device. 25 is a rewritable memory, 26 is a display unit that displays the calling number and called number, or displays the data when used as a data communication device, and 27 is a display unit that displays the data when used as a voice communication device. A telephone call section 28 is a key for inputting a number when making a call.

FIG. 4 shows the control information 24 for realizing the youngest son-style control.
This is a flow chart of part of the contents (incoming call processing program). The process will be explained below according to the flowchart.

When the terminal is in an idle state, communication 1A is performed in step S31.
Receive call settings from 1. Then, in step S32, it is checked whether the calling number is included therein, and if it is, a response is returned to the communication network in step S33, and normal communication with the calling party is performed. If the calling number is not included, a release completion message is sent to the communication network in step S34.

[Other Embodiments] In addition to the method of the present invention, a method of not accepting incoming calls can be considered.

For example, for call setup from a communication network such as l5DN,
A call control procedure may be used in which the communication network operates to disconnect the call if the terminal does not respond for a certain period of time.

The call control procedure of the communication network in this case is shown in FIG.

First, in step 41, the calling party sets up a call to the communication network. The communication network that receives this returns a call setting acceptance to the calling party in step 42, and sends the call setting to the called party in step 43.

The called side sees the contents of the call settings and learns that there is no calling number, so it does not return a response to the communication network in order to avoid accepting the incoming call.

On the other hand, on the communication network side, after the call setting in step 43, a timer is activated to measure the time until receiving a response from the terminal, but here, since the called party does not respond, a timeout is detected. (Step 44) Then, according to the call control procedure, call control for release/release completion is performed in steps 45 and 46, and the calling party and the communication network are disconnected. As a result, the calling party is rejected.

[Effects of the Invention] As explained above, in a terminal connected to a communication network that can notify the called party of the calling party, if the calling party is not notified, the incoming call can be rejected, and the terminal The ways in which it can be used will be enriched.
