Hereinafter, embodiments of the present invention will be explained with reference to the accompanying drawings.
On the basis of a call request from the plurality of connected telephone devices 100 and the telephone repeater 300, the telephone network 50 has a function of establishing a telephone connection with other designated telephone devices 100 or the telephone repeater 300. Here, in a call request, identifier for designating the telephone device 100 or the telephone repeater 300 is called a telephone number. A telephone number can be expressed in any form as far as a telephone device 100 and a telephone repeater 300 can identify the form. The expressive forms are, for example, numeric line, URI (Uniform Resource Identifier) of SIP (Session Initiation Protocol) recited in RFC (Request for Comment) 3261 (http://www.ietf.org/rfc/rfc3261.txt) and the like.
The telephone repeater 300 has a function of connecting with the telephone device 100 (through the telephone network 50), and a function of transferring a telephone call. Here, a call transfer processing will be explained. The call transfer processing makes it possible to establish telephone communication between a telephone device 100(A) which makes a telephone call to the telephone repeater and another telephone device 100(B) when the telephone repeater 300 receives the telephone call from the telephone device.
A called party data storage section 310 is to record information with which the telephone repeater 300 determines a forwarding destination in the call transfer processing by the telephone repeater 300.
For example, the line “09012345678:061111111” means that a telephone call received from a telephone device identified with “09012345678” is to be transferred to a telephone device corresponding to the telephone number “061111111”.
The telephone repeater 300 has a function of obtaining information on a telephone number of a forwarding destination based on, and with reference to, the information within the called party data storage section 310 so as to transfer a telephone call. The network 60 has a function of mediating communication between the telephone device 100 and the telephone call control server 400. An example of the network 60 is such as an internet.
The telephone call control server 400 has functions of performing communication with the telephone device 100 through the network 60 and updating the information within the called party data storage section 310 based on designation of the telephone device 100.
In
The call requesting section 140 in the telephone device 100 is to maintain information on a telephone number of the telephone repeater 300 (hereinafter, a telephone repeater telephone number) and information for identifying the telephone call control server 400 on the network 60 (hereinafter, identification information on the telephone call control server) inside thereof. Here, the call requesting section 140 may maintain a plurality of telephone repeater telephone numbers and identification information on telephone call control servers, and may use each of them depending on indication from the outside.
Here, steps of establishing telephone connection through the telephone network 50 will be explained. Following is an example where the telephone device 100(A) makes a telephone call to the telephone device 100(B). Telephone communication can be performed in the same way as in the case where the telephone repeater 300 is provided instead of one of the telephone devices 100.
At first, the telephone device 100(A) sends a connecting request to the telephone network 50 designating a telephone number of the telephone device 100(B) as a called party. The telephone network 50 notifies the telephone device 100(B) corresponding to the called party telephone number of a telephone connecting request. When the telephone device 100(B) responds, telephone connection is established between the telephone device 100(A) and the telephone device 100(B). Along to the above processing, telephone connection is established.
The telephone network 50 has a function to notify the telephone device 100(B) of a telephone connecting request together with identification information on the telephone device 100(A) based on indication from the telephone device 100(A).
A call transfer processing by the telephone repeater 300 is performed in the following procedure. At first, the telephone repeater 300 receives a telephone call from the telephone device 100(A), and establishes telephone connection with the telephone device 100(A). Then, the telephone repeater 300 makes a telephone call to the telephone device 100(B) designated by the telephone device 100(A) and establishes telephone connection with the telephone device 100(B). Finally, the telephone repeater 300 connects a node of the telephone connection established between the telephone repeater 300 itself and the telephone device 100(A) and a node of the telephone connection established between the telephone repeater 300 itself and the telephone device 100(B) so as to establish telephone connection between the telephone connecting device 100(A) and the telephone connecting device 100(B).
The above described procedure is an example for call transfer processing, and any procedure can be an option as far as it can establish telephone connection between the telephone device 100(A) and the telephone device 100(B).
The present embodiment is different from a conventional system in the point where the telephone device 100 designates a forwarding destination through the network 60 which is different from the telephone network 50 when the telephone device 100 requests call transfer to the telephone repeater 300.
Next, action of a communication system of the present embodiment will be explained specifically with reference to flow charts in
The present processing is performed along with the followings.
(1) A telephone call processing from the telephone device 100 to the telephone repeater 300.
(2) A call transfer processing by the telephone repeater 300.
The detailed explanation for each processing above will be followed.
(1) With Respect to a Telephone Call Processing from the Telephone Device 100 to the Telephone Repeater 300:
This process is performed by the call requesting section 140 within the telephone device 100(A). Flow of the processing performed by the call requesting section 140 will be presented with reference to
Any form of the identification information on the called party may be an option as far as the telephone call control server 400 enables to identify a telephone number of a corresponding telephone device 100(B) with the identification information. Examples of the identification information on the called party are such as a telephone number, a terminal ID, a user ID, and an ID on the network 60, of the telephone device 100(B).
Next, the telephone call requesting section 140 designates the telephone call control server 400 to the data processing section 130 with the identification information on the telephone call control server stored inside so as to request the telephone call control server 400 to send the identification information on the telephone device 100(A) itself and the identification information on the called party obtained by step S11 (Step S12).
Here, any form of the identification information on a telephone device 100(A) itself may be an option as far as the telephone device 100(A) can be certainly identified with the information in the communication system. Examples of the identification information on the telephone device 100(A) are such as a telephone number, a terminal ID, a user ID, and an ID on the network 60, of the telephone device 100(A).
The data processing section 130 is connected to the telephone call control server 400 through the network 60 based on designated identification information on the telephone call control server so as to send the identification information on the telephone device 100(A) and the identification information on the called party. The data processing section 130 may send additional identification information such as an electronic signature and a password when the data processing section 130 is connected to the telephone call control server 400.
Upon receipt of the information from the data processing section 130, the telephone call control server 400 firstly converts the identification information on the called party into a telephone number of the corresponding telephone device. Then, the telephone call control server 400 records a set of identification information on the telephone device 100(A) and the telephone number of the called party (the communication party) as a set of identification information on the caller and the telephone number of the called party as data in the called party data storage section 310. When a telephone number is used as identification information on a called party, this conversion process is not performed.
According to the above, the call requesting section 140 orders explicitly to send identification information on the telephone device thereof, however, the order is not necessary to be explicit. For example, the call requesting section 140 may order to send the identification information on the called party only, and the telephone call control server 400 may obtain the identification information on the telephone device 100 by performing an obtaining process for the identification information on the called party in the communication process with the data processing section 130 of the telephone device 100.
Next, the call requesting section 140 designates a telephone repeater telephone number stored therein so as to request the telephone processing section 120 to make a telephone call to the telephone repeater (Step S13). A telephone processing section 120 notifies the telephone repeater 300 of the identification information thereof through the telephone network 50 based on the designated telephone repeater telephone number so as to perform telephone connection. Here, a formation of the identification information notified is same as one in Step S12.
According to the above processing, a telephone call from the telephone device 100(A) to the telephone repeater 300 is conducted. The process in Step S13 may be performed after a phase in Step 12 mentioned above where the telephone call requesting section 140 has complete confirmation that the telephone call control server 400 finishes a recording processing.
(2) Call Transfer by a Telephone Repeater 300:
The present process is to be performed by the telephone repeater 300. Flow of a process performed by the telephone repeater 300 will be presented with reference to
An example of obtaining the identification information of the telephone device 100(A) of the caller is that the identification information notified by the telephone device 100(A) is received through the telephone repeater 300. If the telephone repeater 300 cannot obtain the identification information of the telephone device 100(A) of the caller, it is determined that no corresponding data is in the called party data storage section 310.
When it is determined that no corresponding data is in the called party data storage section 310 in Step S22, the telephone repeater 300 concludes the transfer processing. When it is determined in Step S22 that there is corresponding data in the called party data storage section 310, the telephone repeater 300 obtains information on the called party telephone number (that is, a telephone number of the telephone device 100(B)) corresponding to the identification information on the caller from the called party data storage section 310, and transfer to the called party telephone number (Step S23).
Specifically, for example, by establishing a telephone connection with the telephone device 100(B) corresponding to the called party telephone number, and connecting the end point to a telephone connection with the telephone device 100(A) of the caller, thereby a telephone connection between the telephone device 100(A) of the caller and the telephone device 100(B) of the called party is established. The call transfer processing is conducted by the telephone repeater 300 along to the above procedure.
When it is determined in Step S22 that there is no corresponding data in the called party data storage section 310, the telephone repeater 300 may determine a forwarding destination as in a conventional way so as to perform a call transfer processing.
In the above, the telephone repeater 300 is to conduct the processing in Step S22 after establishing the telephone connection with the telephone device 100(A) in Step S21. However, when the telephone repeater 300 can obtain the identification information on the telephone device 100(A) upon receipt of a connection request from the telephone device 100(A), the telephone repeater 300 may conduct the processing in Step S22 without establishing the telephone connection in Step 21 and may establish the telephone connection in Step S23.
As described above, according to the communication system in the present embodiment, the telephone device 100 designates a forwarding destination through the network 60. Thus, the forwarding destination can be designated as far as the telephone device 100 has a function of performing a data communication through the network 60.
According to the above embodiment, every telephone device 100 is connected to the telephone repeater 300 through the telephone network 50. However, some telephone devices 100 may be connected directly to the telephone repeater 300 without the telephone network 50. In this case, the telephone repeater has a function of performing a telephone connection with a telephone device which is directly connected thereto. Because of this, a transfer processing can be performed with respect to a telephone device which is not connected to the telephone network 50, such as an extension in an office.
According to the above embodiment, the telephone call control server 400 converts the identification information of the called party to a telephone number so as to store it in the called party data storage section 310, and then the telephone repeater 300 utilizes the telephone number. However, the telephone repeater 300 may converts the identification information to the telephone number, instead of the telephone call control server 400. Specifically, the telephone call control server 400 may store the identification information on the called party as it is in the called party data storage section 310, and then the telephone repeater 300 may convert it to the telephone number after obtaining the identification information on the called party.
According to the above embodiment, in Step S13, a form of the identification information on the telephone device 100 itself, which is notified by the telephone processing section 120, is same as the form of identification information used in Step S12. However, the identification information used in Step S13 may be a formation different from that of Step 12. In this case, the form of the identification information on the caller received by the telephone call control server 400 in Step S12 is different from the form of the identification information on the caller received by a telephone repeater 300 in Step S13, so that a converting processing with respect to the form is to be performed in the telephone call control server 400 or in the telephone repeater 300.
According to the above embodiment, the call requesting section 140 receives a call request from the input/output section 110 in Step S11. However, the call requesting section 140 may receive a call request from other sections than the input/output section 110 such as the data processing section 130. For example, the data processing section 130 may send the call requesting section 140 a call request as a result processed by the user using the data processing section 130, and the call requesting section 140 may receive it. This enables the call requesting section 140 to perform a telephone call in cooperation with the processing at other components of the telephone device.
In the embodiment described above, there is no restriction about the telephone number of the called party, however, contents of the identification information on the called party may be restricted at the call requesting section 140, the data processing section 130, or the telephone processing section 120. Further, the restricted contents may be able to be controlled from outside through the network 60. Thereby, forwarding destinations designated by the user can be limited.
According to the flow charts shown in
According to the present invention as described above, transfer processing can be performed by a telephone repeater even if a telephone device is different in manufacturer or type, and also can be performed by a telephone device having data communication function.
