[0002]

2. Description of the Related Art In the conventional ordinary telephone, when the other party is absent, the caller receives a voice message by the function of an answering machine.
You can record a message. A person who sets up an answering machine (reception side) can know who has called by canceling the function of the answering machine and listening to a message after returning home, for example. However, even if the answering machine function is set, it is the caller who decides whether or not to record a message. I can't know if there was any.

In addition, when the receiving side is already talking to a third party, the call was not established unless the receiving side registered call waiting. Therefore, even in this case, the receiving side cannot know who made the call.

[0004]

As described above, in the conventional telephone, there is a problem that the receiving side does not know who made the call unless the caller records. In addition, when a call is already being made with a third party, the call cannot be made unless the call waiting call is registered, so that there is a problem that it is not possible to know who the call came from.

Further, even in a LAN (local area network) which is a packet switching network, the LAN
When real-time communication is performed between the terminals connected to the receiver, there is a problem that it is not possible to know who made the real-time communication request when the called terminal is not activated.

[0006] A first object of the present invention is to provide a called side (receiving side).
When a real-time communication request is received when the user is absent or already in communication with a third party, a communication system and a communication method that records the history of the real-time communication request so that it can be known from whom the communication request came To provide. Further, a second object of the present invention is to record the history of real-time communication requests so that it is possible to know from whom the communication request came even when the terminal on the receiving side is not activated due to power-off or the like. To provide a communication system and a communication method.

[0007]

In order to solve the above problems, according to the first aspect of the present invention, when a real-time communication request is received, the owner name, time, and mail of the calling communication terminal are By registering history information such as presence or absence, it is possible to provide a communication system having a function of identifying a communication requesting sender from the incoming call history information, and having a function of replying to the sender for real-time communication and storage communication.

According to a second aspect, when a real-time communication request is made and incoming call history information is stored, that history information is displayed on the screen, and when replying to the caller, it is easy to follow the instructions on the screen. Provide a communication system having a function of replying.

A third aspect is that the communication terminal on the real-time communication request transmission side cannot establish a connection with the communication request partner terminal, such as when the communication terminal on the reception side is powered off or the reception task is not activated. Even if a server that performs proxy processing is accessed and a processing with a communication request partner is performed on the server, a communication system that can obtain a history is provided.

[0010]

According to the first aspect of the communication system of the present invention, it is known from whom the communication request is made when the called party is absent or is already communicating with a third party or when a real-time communication request is received when executing incoming filtering. The information on the calling side is known.

According to the second aspect, it is possible to easily make a reply for real-time communication and storage communication from a list of incoming call history while looking at the screen.

According to the third aspect, even if the communication terminal on the receiving side is not activated, the history is notified from the server that performs the proxy processing, so that the history is always recorded when a real-time communication request is made. Obtainable.

If there is a connection connection request from the communication terminal on the receiving side in 09, a connection connection completion notice is issued, a connection is established with the communication terminal on the receiving side, and the request is waited for.

Next, when a request for retrieval of the incoming call history (issued in step 1904 of FIG. 19) is received in step 2010, the address of the called communication terminal included in the history retrieval request notification is acquired in step 2011. . Then, in step 2012, the incoming call history table (FIG. 18) is searched using the incoming call terminal address acquired in step 2011 as a key. If the history information of the called terminal is present in step 2013, the search history data is retrieved in step 2014.
Data to the receiving terminal (received in step 1905 of FIG. 19). If there is no history information of the called terminal in step 2013, the fact that there is no history data is notified to the called terminal in step 2015 (received in step 1908 of FIG. 19).

Next, when the OK command is received in step 2016 (transmitted in step 1909 in FIG. 19), connection disconnection processing is performed in step 2017. In step 2018, it is determined whether or not there is an instruction to end the proxy task, and if there is an instruction, the proxy task is ended. If the instruction is not to end the proxy task, the process returns to step 2002.

FIG. 21 shows an example of the overall processing flow of the communication terminal on the transmission side of the real-time communication request when the proxy server 1701 is present.

In step 2101, a calling task for carrying out a real-time communication request calling process is started, and step 210
In 2, the real-time communication (call) request is transmitted. In step 2103, since the power of the communication requesting terminal is not turned off or the incoming task is not activated, the network is
Determines if the connection could not be reached due to a timeout at the driver level.

If a connection cannot be established with the terminal of the communication request partner, in step 2104 a connection connection request is issued to the proxy server 1701 which performs proxy processing of the incoming call history, and in step 2105 the connection connection request is sent. It waits for a connection connection acknowledgment notification from the proxy server 1701. When the acknowledgment notice is received, the address (IP address or host name, or telephone number) of the communication terminal of the communication requesting party and the name, affiliation, mail presence or absence of the owner of the calling communication terminal are included in step 2106. The history information is notified to the proxy server 1701. Then, in step 2107, an end notification is issued to disconnect the connection with the proxy server 1701. Then, it progresses to step 2109. When the connection connection acknowledgment notification from the proxy server 1701 is not received in step 2105, step 21
Go to 09.

When a connection can be established with the partner terminal performing the real-time communication in step 2103, the real-time communication originating side process shown in FIG. 9 is performed. For this part, FIG. 21 shows an outline of the procedure. That is, when the communication acceptance notification is received in step 913, a call is made in step 914 and the process proceeds to step 2109. If it is not the communication acceptance notification in step 913, it is determined in step 908 whether the communication refusal notification is received. When the communication refusal notification is received, it is determined in step 909 whether or not to send the mail, and if so, the mail is created and sent to the mail server in step 910, and the process proceeds to step 2109. If the e-mail is not transmitted in step 909, an acknowledgment notification is transmitted in step 912 and the process proceeds to step 2109. If it is not a communication refusal notification in step 908, it is determined in step 2108 whether a time-out has occurred.
If the time is not out, the process proceeds to step 913.

According to the present embodiment, the proxy server performs the proxy processing of storing and storing the incoming call history when the power of the receiving terminal for the real-time communication request is turned off or when the incoming task is not activated. Therefore, a communication system capable of collecting the incoming call history all day becomes possible.

In the fourth embodiment, when the incoming call task is not activated on the incoming call side terminal, the server always collects the incoming call history concerning the incoming call side terminal.
After the activation of the incoming call task, the incoming call terminal always inquires of the server whether or not there is an incoming call history addressed to itself. However, when terminating the incoming call task at the receiving terminal, the server requests that the server keep an incoming call history, and the server only takes the incoming call history for the requested terminal. You may do it.

In the first to fourth embodiments, the case where the present invention is applied to the case where voice data is communicated in real time, that is, the voice call is explained, but the data transmitted and received by the real time communication is not limited to voice. .
