Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multimedia communication terminal, and more particularly to a multimedia communication terminal equipped with means for arbitrarily selecting a communication medium and means for selecting a connection refusal reason on the terminal side receiving a call setting request message. Regarding media communication terminals.

[0002]

2. Description of the Related Art Conventionally, in the communication terminal disclosed in Japanese Unexamined Patent Publication No. 4-220856, a caller number for which connection is permitted is registered in a connection terminal list, and when a call is received, the caller number received and the connection terminal list are registered. By collating the caller number registered in, the call setup request message is sent when the collation matches, and the disconnection response message is transmitted when the collation does not match.
Whether to connect to the line is determined. In addition, by sending a disconnection response message including the connection refusal reason when the collation does not match, the reason why the called side refuses the line connection is clarified.

However, this prior art does not consider the point of selecting a communication medium when selecting a line connection. In addition, when selecting connection refusal, consideration is not given to displaying an appropriate reason for connection refusal created by the user on the calling side. Further, no consideration is given to automatically rejecting a call setup request message from a party who once refused the connection.

[0004]

In the above-mentioned prior art, the receiving side selects the line connection only to the party registered in advance, but does not select the communication medium to be transmitted / received after the line connection. Therefore, it is necessary to send media information, which is inconvenient for the called party, to the other party, and there has been a problem related to information infringement.

Further, the called side notifies the calling side of the same reason for connection refusal when the connection refusal is selected, without creating an arbitrary reason for connection refusal. Therefore, when the called side refuses the connection, there is a problem that the calling side recognizes an appropriate reason for the connection refusal and the calling side cannot efficiently move to the next operation or action according to the reason for the connection refusal.

Further, since connection refusal is selected for an incoming call from a partner who is not registered in the connection terminal list, there is a problem that communication cannot be started with a partner who has missed registration.

An object of the present invention is to make it possible to select line connection or connection refusal for an incoming call from any other party. When the line connection is selected, communication is started by a medium convenient for the called side and connection refusal is selected. In this case, the line connection method of the communication system that notifies the caller of the appropriate reason for connection refusal registered by the called party and automatically rejects if there is a connection request message from the other party who refused again. To provide.

[0008]

To achieve the above object, the present invention provides a user interface capable of selecting line connection or connection refusal and a user interface capable of selecting a communication medium on the receiving side. When a line connection is selected, a connection response message containing the identifier of the selected communication medium is sent to the calling side, and then both the calling side and the called side start transmitting and receiving communication media according to the communication medium identifier.

Further, a user who can register the reason for connection refusal
An interface and a user interface that can arbitrarily select a plurality of registered connection refusal reasons are provided, and when a connection refusal is selected, a disconnection response message including the selected connection refusal reason is transmitted to the calling side.

Further, when the connection refusal is selected, the caller number is registered in advance, and when the caller number received afterwards matches the registered caller number, a disconnection response message is transmitted to the caller side.

[0011]

According to the present invention, when a line is connected to an incoming call from any other party, the line is connected by transmitting a connection response message including the identifier of the selected communication medium to the calling side. Communication can be started with any other party, and it is possible to prevent the information confidentiality of the called party from being violated.

Further, according to the present invention, when the connection is rejected, the user selects a connection rejection reason created in advance,
By sending a disconnection response message together with the rejection reason to the calling side and displaying the rejection reason on the screen, the calling side can be notified of the appropriate rejection reason created by the called side.

Further, when rejecting the connection, when the registered caller number and the caller number received again are the same, a disconnection response message is sent to the other party, so that the connection from the once rejected party is automatically made. You can refuse.

FIG. 9 shows a flow in the case of selecting a communication medium when a line is connected and selecting a refusal reason when rejecting a connection when receiving a call setting request message in the present invention. A program for executing some of the flowcharts shown below is read and processed by the centralized control processor unit 1110. The reason for connection refusal shall be registered in advance by the user.

First, it waits until a call setup request message, connection response message or disconnection response message is detected from the network (100). Next, the detected message is discriminated (200). When the call setting request message is received, the other party is displayed on the screen, and then it is determined whether the connection is selected or rejected by the user (300). If it is a connection, the request message of the communication medium is discriminated (400), and, for example, if the communication is a video and audio medium, a connection response message storing the AV identifier is transmitted (410). The same applies to other media. If the connection is rejected, the registered connection rejection reason is determined (500). For example, if "call later", a disconnection response message storing the reason is transmitted to the other party (510). When the connection response message is received, the communication media identifier is discriminated (600), and the communication is started by outputting the media corresponding to the identifier (610 to 640). When the disconnection response message is received, the reason for connection refusal is displayed on the monitor (70
0).

FIG. 10 shows an operation example when the user who receives the call setting request message selects the connection and selects the communication in the audio and video media. First, in step (1), the terminal station 1000a transmits a call setup request message to the terminal station 1000b. Terminal station 1000 in step (2)
When b receives the call setting request message, the other party is displayed on the screen, and when the user B selects "1. Other party voice / video communication" 31 from the media list, the identifier (A / V identifier) is selected in step (3). ) Is sent to the terminal station 1000a. When the terminal station 1000a receives the connection response message in step (4), the communication line is connected. At this time, both end stations display on the screen that communication is performed by audio and video, and the terminal station 1000a transmits the audio and video data of the user A to the terminal station 1000b from the received communication media identifier and the terminal station 1000b also transmits the data. B
The audio and video data of the above is transmitted to the terminal station 1000a. As a result of converting the other party's data received by each terminal into audio and video signals and outputting them from the speaker 1500 and the monitor 1300, it becomes possible to communicate using the audio 1510 and the video 1310 as media.

Further, regarding an operation example in which the user who receives the call setup request message selects the connection refusal 22 and sends the reason to the other party, for example, when the terminal station 1000b receives the call setup request message, the user B refuses. Reason list 5
If 0 is selected, for example, "I'm busy now, I'll call you later" 51, the terminal 1000b sends a disconnection response message including the reason (text data) to the terminal 1000a, and refuses the connection. When the terminal station 1000a receives the disconnection response message, the reason for the connection refusal is indicated by the terminal station 1000a.
(700). Therefore, the user B can inform the user A of an appropriate reason for refusing the connection.

Next, in the present invention, a flow in the case of automatically rejecting the incoming call from the other party who once refused the connection is shown in FIG. This flowchart starts when a call setup request message is received with the message type (200) in FIG. When the call setup request message is received, the connection rejected terminal list is searched for the received call number,
The presence or absence is determined (250). If there is no call number, "connection" or "connection refusal" is discriminated (300). If "connection refused", the received call number is registered in the connection refused terminal list (320), and a disconnection response message is transmitted (33).
0). If the call number exists in the connection refusal terminal list, the disconnection response message is automatically transmitted (500). However, the call numbers in the connection refusal terminal list can be deleted by the user.

Here, regarding an operation example in the case of automatically rejecting an incoming call from the other party who once refused the connection,
For example, when the terminal station 1000b receives the call setup request message and the user B selects "connection refusal" 22, the terminal station 1000b registers the other party's call number in the connection refusal terminal list and sends a disconnection response message. Reject the connection. When the terminal station 1000b receives the call setup request message again, it collates the received call number with the call number in the connection refusal terminal list. Since the collations match, the terminal station 1000b sends a disconnection response message to the other party and rejects the connection.
Therefore, the terminal station 1000a cannot call the terminal station 1000b unless the call number of the terminal station 1000a is deleted from the connection refusal terminal list.

FIG. 12 shows a flow chart in the case where the call is automatically sent to the other party who refused the connection after a fixed time. This flow chart starts when the user selects "call later" as the reason for connection refusal in the registration refusal reason type (500) in FIG.
First, the other party's call number is stored (510). Next, the reason for connection refusal is stored in the disconnection response message and transmitted (520) and the timer is started (530). It waits until the expiration of the timer is detected (540), and when the timer expires (541), sends a call setup request message (54
2) The stored call number is deleted (543). The call setup request message receiver follows the flow from 300 onward.

An example of the operation in the case where a call is automatically transmitted to the other party who refused the connection after a fixed time, for example, the terminal station 1000
When the terminal station 1000b receives the call setting request message from a, when the user B selects "I will call later because I am busy" 51 as the reason for connection refusal, the terminal station 1000b stores the call number of the other party in the main memory 1113. Then, the disconnection response message is transmitted, the connection is once refused, and the timer is started. Terminal station 10 that received this disconnection response message
00a displays the reason for refusal on the monitor. When the timer expires, the terminal station 1000b sends a call setup request message to the other party of the stored call number. The subsequent operation is the same as in FIG. Therefore, the connection refused partner can be automatically called after a fixed time.

Further, in the present invention, the flow of the case of automatically making a call after the end of the call to the other party who received the call during the call is shown in FIG.
3 shows. It is assumed that this flowchart waits until an event from the network or the user is detected. First, the event destination is determined (200), and if it is an event from the network, the received communication frame is determined (300). When the call setting request message is received, it is determined whether or not the call is in progress (310), and if the call is in progress, the call number is stored in the main memory 1113 (311), and "call in progress (reason for connection refusal)". Send disconnection response message including "(3
12). When a disconnection response message is received from the other party who is talking, if a stored call number exists (330), a call setup request message is sent to the other party with that call number (33).
1) The stored call number is deleted from the memory (332). Also, when an event from the user is detected and the user selects "disconnect", a disconnection response message is transmitted to the other party who is talking (410). At this time, if a stored call number exists, a call setup request message is sent to the other party of that call number.
(421), The stored call number is deleted from the memory (422).

FIG. 14 shows an operation example in the case of automatically making a call to the other party who has received a call during the call after the call is completed. Here, it is assumed that a call is being made between the user A and the user B. At this time, when the terminal station 1000b receives the call setup request message from the terminal station 1000c in step (1), the call number of the other party is stored in the main memory 1113, and in step (2), "calling (reason for connection rejection) ) ”Is included in the response message and the connection is rejected. The terminal station 1000c receiving the disconnection response message in step (3) displays the reason for refusal on the monitor. The terminal station 100 for ending the communication in step (4)
When the terminal station 1000b receives the disconnection response message transmitted by 0a, the communication lines between the users A and B are disconnected. Since the accumulated call number exists in the terminal station 1000b, the call setting request message is transmitted to the terminal station 1000c corresponding to the call in step (5). The operation after step (6) is the same as that in FIG. Therefore, after the call ends, the other party who has received the call during the call can be automatically called.

[0032]

According to the present invention, it is possible to start communication according to the communication medium selected by the user in response to an incoming call from an arbitrary partner. Communication can be started and transmission / reception of communication media unnecessary for the receiving side can be prevented.

Further, according to the present invention, since it is possible to reject the connection and notify the other party of the reason for the connection refusal created in advance by the user, the calling side performs the next operation or action according to the reason for the connection refusal. Can be efficiently transferred to.

Further, since the connection can be rejected when the caller number registered at the time of rejecting the connection and the caller number received again are the same, the user is not required to respond to the connection request from the other party once rejected. Can be automatically rejected.
