Then, after the call control unit 17 obtains the response destination information and confirms the call path connection request, the other party call path formed by the response to the other party call and the terminal call path formed by the response to the terminal call Are connected via relay.

  As a result, a telephone incoming call service for making a voice call in response to the incoming call from the other party telephone terminal 30 notified from the telephone network 40 or the mobile network 50 connected to the telephone control apparatus 10 by the radio telephone terminal 20 is provided. In the case of providing, among the voice communication paths connecting the radio telephone terminal 20 and the other party telephone terminal 30, the terminal communication path between the radio telephone terminal 20 and the telephone control device 10 is a communication path using the mobile network 50. Formed with. Therefore, stable call quality can be obtained as compared with a case where a terminal call path is formed using IP communication which is a best effort type. For this reason, it is possible to provide a telephone service with stable call quality from the telephone system 1 to the radio telephone terminal 20.

  At this time, in response to a request from the radio telephone terminal 20, the telephone control device 10 needs response destination information such as the telephone number of the other party telephone terminal 30 when responding to the other party telephone terminal 30. Become. Therefore, before the telephone control device 10 performs relay connection in response to the incoming call from the other party telephone terminal 30, response destination information for identifying the incoming call to be answered from the wireless telephone terminal 20 to the telephone control apparatus 10 is provided. You need to be notified.

  However, when a voice communication service of the mobile network 50 is used to make a telephone call from the radio telephone terminal 20 to the telephone control device 10 to form a terminal communication path, the destination telephone number sent from the radio telephone terminal 20 is only a telephone. This is the telephone number of the control device 10. For this reason, there is a problem in that the response destination information regarding the other party telephone terminal 30 that is the original response destination is not notified from the radio telephone terminal 20 to the telephone control device 10 when making a telephone call for forming a terminal communication path.

  On the other hand, in the present embodiment, focusing on the fact that the voice call service of the mobile network 50 and the data communication service can be used together, the voice call service of the mobile network 50 is changed according to the outgoing operation at the radio telephone terminal 20. Utilizing the data communication service of the mobile network 50 in parallel with the operation of making a telephone call for forming a terminal communication path to the telephone control device 10 by using the data communication service of the mobile network 50, the response from the radio telephone terminal 20 to the telephone control device 10 This is notified as response destination information for identifying an incoming call to be made.

Thereby, according to the response operation at the radio telephone terminal 20, it is possible to collectively form the terminal call path and notify the response destination information of the other party telephone terminal 30.
Therefore, the terminal communication path between the radio telephone terminal 20 and the telephone control device 10 can be easily formed in the mobile network 50 without giving an operation burden to the user of the radio telephone terminal 20. For this reason, as a result, the usability is improved and the telephone service can be used smoothly.

  Further, in the present embodiment, in the telephone control device 10, the distribution unit 14 distributes a Web screen for notification of incoming calls, that is, an incoming notification screen, in response to the notification of the other party's incoming call, and the radio telephone terminal 20 displays the screen. Based on the response operation performed on the incoming call notification screen, response destination information is obtained from the response notification confirmation unit 15 from the response notification notified from the wireless telephone terminal 20 through data communication via the mobile network 50. It is a thing.

  Thereby, the radio telephone terminal 20 displays the Web screen distributed from the telephone control device 10 on the screen, and transmits arbitrary data to the telephone control device 10 in accordance with the operation on the Web screen by the user. The response notification can be notified to the telephone control device 10 via the mobile network 50 only by operating a typical browser function.

In a general telephone system, when a telephone service similar to that of an extension telephone terminal is provided from a telephone control device to a wireless telephone terminal, control messages are exchanged with the wireless telephone terminal.
However, the control message used when controlling the operation of the wireless telephone terminal is defined by the telephone system, for example, like the control data exchanged with the extension telephone terminal. This is because it is required to control the unique function of the telephone system.

  For example, when an external line is transmitted from a wireless telephone terminal using an external line of a telephone control device, a predetermined control message is transmitted to the telephone control device in response to a user operation at the wireless telephone terminal. At this time, the control message transmitted from the wireless telephone terminal to the telephone control device stores various data such as the request message for requesting an outside line transmission, the telephone number of the terminal itself, the telephone number of the destination. There is a need to. For this reason, it is necessary to generate and transmit a control message at the radio telephone terminal in accordance with the internal configuration of the control message used in the telephone control device.

  Therefore, the standard functions of wireless telephone terminals such as general mobile phone terminals that are commercially available cannot access the telephone control device based on the control message unique to the telephone system. The operation of the radiotelephone terminal cannot be controlled based on the control message from.

  In such a case, it is necessary to add a function for operating the wireless telephone terminal based on the control message unique to the telephone system to the wireless telephone terminal, specifically, a special program for connecting to the telephone system. Must be created and installed in advance on the wireless telephone terminal. In addition, since each mobile phone service provider has a different program language that can be executed on each mobile phone terminal, it is necessary to create a program for each language. For this reason, there is a problem that the telephone service of the telephone system cannot be easily used from a general commercially available wireless telephone terminal.

  According to the present invention, since the Web screen used for the operation when using the telephone service is distributed from the telephone control device 10 to the wireless telephone terminal 20, the general commercially available wireless telephone terminal 20 equipped with a browser function can be used. The telephone service of the telephone system 1 can be easily used. The browser function conforms to standards such as HTTP and HTML, and any browser function installed in the mobile phone terminal of each mobile phone service provider has a common function.

  As a result, it is not necessary to install a special application on the radio telephone terminal 20, and the installation work borne by the user of the radio telephone terminal 20 can be omitted. Further, the cost for developing a special application can be saved, and there is no need to create a program in a different language for each mobile phone service provider. Therefore, it is possible to greatly reduce the operation cost of the telephone service.

  Further, in response to a response operation on the Web screen in the radio telephone terminal 20, a response notification can be notified to the telephone control device 10 by data communication such as HTTP via the mobile network 50. For this reason, it is possible to notify the response notification promptly without delaying the telephone call for forming the terminal communication path as compared with the case where the response notification is notified by storage-type data communication such as e-mail. Therefore, the user of the radio telephone terminal 20 can use the telephone service very smoothly by a simple operation of operating the call button on the Web screen.

  In the present embodiment, in the telephone control device 10, for each wireless telephone terminal 20, the wireless terminal information in which the terminal identification information and the mobile phone number of the wireless telephone terminal 20 are registered is stored in the storage unit 18. When the call control unit 17 performs relay connection, the response notification confirmation unit 15 obtains response destination information and the connection request confirmation unit 16 confirms the call path connection request within a predetermined time. In addition, based on the wireless terminal information stored in the storage unit 18, the terminal identification information included in the response notification from the wireless telephone terminal 20 and the transmission source telephone number notified when the incoming call from the mobile network 50 is the same wireless When it is confirmed that the telephone terminal 20 belongs, the relay connection to the partner telephone terminal 30 is performed.

  As a result, the telephone control device 10 can accurately identify the response notification and the incoming call from the same radio telephone terminal 20. Therefore, even when each response notification is received from a plurality of wireless telephone terminals 20 at the same time or when a plurality of terminal calls from the mobile network 50 are generated at the same time, the response destination information notified by the response notification is used. It is possible to accurately relay-connect the other party communication path on the other party telephone terminal 30 side and the terminal communication path on the radio telephone terminal 20 side formed in response to the terminal incoming call.

  Further, in the present embodiment, when the distribution unit 14 receives a screen request from the wireless telephone terminal 20 through data communication via the mobile network 50, the incoming call notification to the wireless telephone terminal 20 is sent to the telephone network 40 or the mobile network. The connection to the wireless telephone terminal 20 for distributing the Web screen for notification of incoming calls to the wireless telephone terminal 20 is maintained by temporarily stopping the response to this screen request until notified from 50. Thus, in response to the incoming call notification to the radio telephone terminal 20, the web screen for the incoming call notification can be immediately distributed to the radio telephone terminal 20.

  In general, general data communication using HTTP is a so-called pull-type data communication method in which contents on the server side are extracted from the client side, and can be arbitrarily sent to the client side at an arbitrary timing according to the occurrence of an event on the server side. Cannot deliver content. For this reason, in pull-type data communication, the incoming call notification screen cannot be distributed from the telephone control device 10 to the radio telephone terminal 20 at the timing when the incoming call notification is received from the network side.

  According to the present embodiment, since the response to the screen request transmitted from the telephone control device 10 is temporarily stopped in response to the screen request from the wireless telephone terminal 20, the wireless telephone terminal 20 side Can be put in a state of waiting for a response to the screen request. As a result, it is possible to maintain a connection with the radio telephone terminal 20 for delivering a web screen for incoming call notification to the radio telephone terminal 20. Therefore, the incoming call notification screen can be immediately delivered to the radio telephone terminal 20 in response to the incoming call notification from the telephone network 40 or the mobile network 50. As a method for temporarily stopping the response to the screen request from the radio telephone terminal 20, a general push data communication method such as COMET, Flash (registered trademark), HTML5, or the like may be used. .
