  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing the overall configuration of the present embodiment. Referring to FIG. 1, an IP telephone system 1000 includes a smart device 100, a docking station main body 200, a business handset section 300, an IP telephone exchange 400, a UC (Unified Communication) server 500, a PC (Personal computer) 600, and an IP telephone 700. And a data switch 800.

  In this embodiment, the smart device 100 introduced on the IP telephone system 1000 is combined with a docking station (a combination of the docking station main body 200 and the business handset unit 300), and the handset unit 300 of the familiar business telephone and the smart device 100 are combined. Realize sharing of calls.

  Here, the IP telephone system 1000 shown in FIG. 1 is only one configuration example, and all of the devices shown in FIG. 1 do not necessarily have to exist. The IP telephone system 1000 may further include other devices, and the number of each device may be an arbitrary number. It is assumed that the IP phone system 1000 is constructed in the office of the company where the user works. In the following description, the combination of the docking station main body 200 and the business handset unit 300 is appropriately referred to as “the present docking station”.

  The smart device 100, the docking station main body 200, and the business handset unit 300 will be described later. First, the IP telephone exchange 400 and the UC server 500 will be described.

  The IP telephone exchange 400 is realized by, for example, a SIP server compliant with SIP, and processes the SIP request. Specifically, the IP telephone exchange 400 is used for extension communication, which is voice communication between devices in the IP phone system 1000, or voice communication between a device in the IP phone system 1000 and a device outside the IP phone system 1000. It plays the role of relaying certain outside line communications.

  The UC server 500 is a server that integrates functions for realizing communication services such as instant messaging, presence information, telephone calls, video conferencing, call control, and voice recognition services.

  The IP telephone exchange 400 and the UC server 500 may each be realized by a single device, but either or both of the IP telephone exchange 400 and the UC server 500 may be realized by a plurality of devices. Furthermore, both the IP telephone exchange 400 and the UC server 500 may be realized by a single device.

  In the present embodiment, the smart device 100, the docking station main body 200, the business handset unit 300, the IP telephone exchange 400, and the UC (Unified Communication) server 500 are the main points. Therefore, a PC (Personal computer) 600, an IP telephone 700 Description of the data switch 800 is omitted.

  Next, the configuration of the smart device 100, the docking station main body 200, and the business handset unit 300 will be described with reference to FIG.

  Referring to FIG. 2, the smart device 100 includes a camera 101 and a touch panel 102. The docking station main body 200 includes an RF communication unit 201, a camera 202, a RAM 203, a ROM 204, a CPU 205, a display 206, a USB (Universal Serial Bus) unit 207, a USB unit 208, and a LAN interface 209. Further, the business handset unit 300 includes a camera 301, a display 302, operation buttons 303, and a charging unit 310.

  The smart device 100 is realized by, for example, a multi-function mobile phone called a smartphone, but may be realized by a PHS (Personal Handy-phone System) or the like.

  The camera 101 is used for reading an image, and there is no particular limitation on fine performance such as resolution. The touch panel 102 realizes both a display function and an operation reception function. Needless to say, the display function and the operation reception function such as a display and operation buttons may be realized by separate devices. The smart device 100 is connected to the docking station main body 200 via the USB cable 210 and can be charged thereby. Alternatively, the docking station body 200 and the smart device 100 may transmit and receive data via the USB cable 210.

  The RF communication unit 201 is a part for performing wireless communication with the business handset unit 300. Although there is no particular limitation on the communication method, the Bluetooth standard, the DECT (Digital Enhanced Cordless Telecommunications) standard, or the like can be adopted. Needless to say, the business handset unit 300 may be connected to the docking station main unit 200 via a wired connection like a standard IP telephone. That is, the docking station body 200 and the business handset unit 300 may be realized in a separate format or may be integrated.

  The camera 202 is used for reading an image, and there is no particular limitation on fine performance such as resolution.

  A CPU (Central Processing Unit) 205 reads software stored in a ROM (Read Only Memory) 204 and executes the software while using a RAM (Random Access Memory) 203 to control the docking station main body 200 as a whole. To do.

  The display 206 is a display device for displaying an image. The USB unit 207 and the USB unit 208 comply with the USB standard, and supply power to the smart device 100 via the USB cable 210. Further, the USB unit 207 and the USB unit 208 are not limited to functions as charging terminals, but also have a function as a docking interface with the smart device 100. That is, the USB unit 207 and the USB unit 208 also operate as an interface for the docking station body 200 and the smart device 100 to transmit and receive data.

  The LAN interface 209 is an interface for communicating with other devices included in the IP telephone system 1000. The LAN interface 209 is realized by a wired Gigabit LAN interface, a wireless WiFi (wireless fidelity) interface, or the like.

  The USB cable 210 is a cable compliant with the USB standard.

  In the present embodiment, it is assumed that the smart device 100 and the docking station main body 200 are connected in accordance with USB. This is because the design of smart devices varies among development manufacturers and many products are released, but it is considered that the functional usage as battery charging is almost unified to the USB standard. However, the connection between the smart device 100 and the docking station main body 200 is not limited to the USB standard, and the connection may be made by an arbitrary method.

  The camera 301 is used for reading an image, and there is no particular limitation on performance such as resolution.

  The display 302 is used to present information to the user. The operation button 303 includes a numeric keypad, for example, and accepts input of a telephone number from the user.

  The charging unit 310 is a charger for charging the business handset unit 300.

  In the present embodiment, the docking station main body 200 and the business handset unit 300 realize natural communication that is easier to use in the office for the smart device 100 installed in the IP telephone system of the office.

  Here, when the smart device 100 is introduced into the office IP telephone system 1000, a soft phone-like telephone function application that operates according to the SIP protocol or the like that can be installed in the smart device 100 from the viewpoint of extension control in the office. Include.

  Note that the docking station is also described in Patent Document 2, for example. However, the docking station described in Patent Document 2 refers to extensibility for a media player that reproduces music and video moving images. That is, the background is fundamentally different from the applications and application examples of the docking station including the business handset, such as the docking station main body 200 and the business handset unit 300 of the present embodiment.

  Next, the operation of this embodiment will be described. In the present embodiment, it is possible to satisfy the following three requirements that arise when the smart device 100 is used in the IP telephone system 1000.

  First, the first request will be described. There is a request to make a call using the business handset unit 300 for both incoming calls to the smart device 100 or incoming calls to the business handset unit 300 when there is an incoming call in the office. This is the first request.

  Next, the second request will be described. For example, it is assumed that a call started using the smart device 100 outside the office is ongoing. Then, when returning from outside the office to the inside of the office and mounting the smart device 100 on the docking station, there is a request to continue using the business handset unit 300 while the smart device 100 is currently talking. This is the second request.

  Finally, the third request will be described. Suppose that a call is made using the business handset unit 300 at an office desk, but the user must stand up. In this case, there is a request to continue the call by switching the call using the business hand unit 300 to the call using the smart device 100. This is the third request.

  An operation for solving each of these three requests will be described.

  A process for satisfying the first request will be described with reference to FIG.

  In this process, in the scene where there is an incoming call to the user in the office where the IP telephone system 1000 is constructed, the incoming call to the smart device 100 or the incoming call to the business handset unit 300 is either a business handset. The request to respond by the unit 300 is satisfied.

  It is assumed that the smart device 100 is currently on the docking station main body 200. Then, the docking station body 200 recognizes that the smart device 100 is attached when charging by the USB unit 207 or the USB unit 208 is started. Instead of triggering charging, a sensor may be added to the docking station body 200 and the smart device 100 may be detected by this sensor. The docking station main body 200 identifies the smart device 100 by an arbitrary method. For example, the docking station main body 200 and the smart device 100 transmit and receive data via the USB unit 207 and the USB cable 210. Then, information for identifying the smart device 100 is included in this data. As a result, the docking station body 200 recognizes that the connected terminal is the smart device 100. A dedicated USB unit for connecting the smart device 100 or a dedicated connection socket may be determined in advance. Then, when a device is connected to the determined dedicated USB unit or dedicated connection socket, it may be recognized that the smart device 100 is connected without transmitting / receiving data. The docking station main unit 200 and the smart device 100 according to the present embodiment identify which device is the transfer destination device at the time of connection, and then inquire to the IP telephone exchange 400 or the UC server 500 based on the identification information. It is also possible to acquire the URI or IP address of the transfer destination.

  Then, the docking station main body 200 that recognizes that the smart device 100 is attached notifies the IP telephone exchange 400 and the UC server 500 to that effect.

  By this notification, the IP telephone exchange 400 and the UC server 500 in the IP telephone system 1000 confirm that the smart device 100 is attached to the docking station main body 200. After the IP telephone exchange 400 and the UC server 500 confirm, the incoming call for the application on the smart device 100 is sent to the business handset unit 300 on the docking station side.

  Then, the business handset unit 300 on the docking station side is ringed, and the telephone call by the business handset unit 300 is realized.

  This processing can be realized by various methods using the sound separation processing by the IP telephone exchange 400 or the UC server 500. For example, as a notification that the smart device 100 is attached to the docking station, the docking station main body 200 receives a REGISTER message that is a contact address registration request, an SIP URI (Uniform Resource Identifier) of the smart device 100, a book The IP address assigned to the docking station is transmitted.

  Then, the IP telephone exchange 400 or the UC server 500, which has a function as a registration server, uses the combination of the SIP URI of the smart device 100 and the IP address assigned to the docking station as a contact address to the location server. sign up. As a result, incoming calls addressed to the SIP URI of the smart device 100 are transferred to the business handset unit 300 thereafter. The IP telephone exchange 400 or the UC server 500 may manage the SIP URI and IP address of the smart device 100 and the docking station in advance. Then, the docking station body 200 may only notify that the smart device 100 is attached to the docking station. In this case, the IP telephone exchange 400 or the UC server 500 that has received the notification registers a set of the SIP URI of the smart device 100 and the IP address assigned to the docking station as a contact address. Further, the function of the location server may be included in the IP telephone exchange 400 or the UC server 500, but may be included in another device.

  Further, the smart device 100 may notify the IP telephone exchange 400 or the UC server 500 instead of notifying the docking station main body 200.

  As a result, when the smart device 100 is attached to the docking station, the business handset unit 300 can be used for incoming calls addressed to the smart device.

  Next, prior to describing the process for satisfying the second request and the process for satisfying the third request, a means for sharing an SIP session in a SIP-compliant call will be described. For sharing, the smart device 100 or the docking station establishes a session in accordance with a standardized technology defined in RFC3261 established by, for example, IETF (Internet Engineering Task Force).

  Further, in the present embodiment, in parallel with the establishment of the session, the IP telephone exchange 400 and the UC server 500 cooperate to acquire session information.

  This session information is acquired when the cooperation application for linking the smart device 100, the IP telephone exchange 400, and the UC server 500 specifies a SIP session by applying CALL-ID or an HTTP session by using cookie information. Realized. Specifically, the smart device 100 and the docking station acquire HTTP session information in cooperation with the UC server 500. The UC server 500 shares CALL-ID information with the IP telephone exchange 400. Therefore, the smart device 100 and the docking station can acquire SIP session information in cooperation with the UC server 500.

  These pieces of information are converted into a two-dimensional code and displayed on the display 206 of the docking station 200 and the touch panel 102 of the smart device 100. Then, the two-dimensional code is read by the camera unit 202 of the docking station 200 or the camera 101 of the smart device 100, and the session is transferred. As a result, it is possible to switch calls without interrupting the call from either the smart device 100 or the handset unit 300 of the docking station to the other. An example of such acquisition of session information is described in cited document 3.

  Next, transfer processing according to this embodiment will be described with reference to the sequence diagrams of FIGS. In FIGS. 4A to 4D, it is assumed that A is a call partner terminal and is the call partner IP telephone 900 shown in FIG. Further, B is assumed to be the smart device 100 or the business handset unit 300 that is the transfer source terminal. Further, C is a transfer destination terminal, which is either the smart device 100 or the business handset unit 300 and not the transfer source terminal. This time, the IP telephone exchange 400 functions as a proxy server and plays a role of relaying communication between the terminals. That is, although not shown, between the AB and the BC, the IP telephone exchange 400 exists and relays each communication.

F1 to F4 in FIG. 4A show a call sequence. When F1 to F4 are specifically described on the assumption that the communication partner terminal A is a caller,
F1: A request (INVITE) for starting a session is sent from the caller terminal A, which is the caller, to the transfer source terminal B. F2: The caller terminal A, which is the caller, is currently calling from the transfer source terminal B ( If the phone rings the bell!) (180 Ringing)
F3: Notifying that the session start request has been accepted from the transfer source terminal B to the calling party terminal A that is the transmission source (200 OK)
F4: Notify (ACK) that the 200 OK response has been received from the calling party terminal A, which is the transmission source, to the transfer source terminal B.

  Note that the transfer source terminal B may be the call source, and in this case, the transmission direction of messages exchanged between the call partner terminal A and the transfer source terminal B is reversed in F1 to F4.

  F1-F4 establishes a call by RTP (Real-time Transmission Protocol) between the call partner terminal A and the transfer source terminal B (Both Way RTP Media).

  F5 to F27 represent a sequence when the call is transferred from the transfer source terminal B to the transfer destination terminal C. F5 to F27 are started, for example, when the two-dimensional code display button of the transfer source terminal B is pressed.

First, F5 to F7 are examples of processes executed at the call partner terminal A and the transfer source terminal B.
F5: A request to hold the call (INVITE (HOLD)) is sent from the transfer source terminal B to the call partner terminal A. F6: The call partner terminal A notifies the transfer source terminal B that the request to hold the call has been accepted. (200 OK)
F7: Notify (ACK) that the 200 OK response has been received from the transfer source terminal B to the call partner terminal A.

  As a result, the call is put on hold while the session is established between the call partner terminal A and the transfer source terminal B.

Simultaneously with F5 to F7, information corresponding to the processes F8 to F14 in FIG. 4-2 is converted into two-dimensional data and displayed as a session on the transfer source terminal B display. Then, the displayed content is two-dimensionally encoded and read by the transfer destination terminal C. In particular,
F8: A request (INVITE) for starting a session is sent from the transfer source terminal B to the transfer destination terminal C. F9: The transfer destination terminal C notifies the transfer source terminal B that it is currently calling (180 Ringing).
F10: The transfer destination terminal C informs the call partner terminal A that the session start request has been accepted (200 OK).
F11: Notify (ACK) that the 200 OK response has been received from the transfer source terminal B to the transfer destination terminal C.
F12: A request to hold the call (INVITE (HOLD)) is sent from the transfer source terminal B to the transfer destination terminal C. F13: The transfer destination terminal C notifies the transfer source terminal B that the request to hold the call has been accepted. (200 OK)
F14: Notify (ACK) that the 200 OK response has been received from the transfer source terminal B to the transfer destination terminal C.

  As a result, the call is put on hold while the session is established between the transfer source terminal B and the transfer destination terminal C. In this way, by establishing a session between the transfer source terminal B and the transfer destination terminal C in advance and placing the session on hold, the transfer destination terminal C is prohibited from responding to calls other than the transfer from the call partner terminal A. . Therefore, it is possible to prevent the transfer destination terminal C from establishing a session with terminals other than the call partner terminal A and the transfer source terminal B before transfer from the call partner terminal A described later is performed. Thereby, in this embodiment, there exists an effect that the transfer from the other party terminal A mentioned later can be performed reliably.

Thereafter, when the transfer destination terminal C receives the two-dimensional code as a trigger, the call to the call destination terminal A is delivered to the transfer destination terminal C by the process of F15 to F21 by the transfer source terminal B, and is transferred after F22. The call with the transfer source terminal B is disconnected from the destination terminal C and the call partner terminal A.
F15: The transfer source terminal B requests the call partner terminal A to make a call to the transfer destination terminal C (REFER Refer-To: C).
F16: Call partner terminal A replies to transfer source terminal B that the request has been accepted (202 Accepted).
F17: The other party terminal A transmits a NOTIFY request to the transfer source terminal B to notify the processing state regarding the request in F15. This time, it is notified that the call between the call partner terminal A and the transfer destination terminal C has not been established yet.
F18: The transfer source terminal B that has confirmed the NOTIFY request returns a 200 OK response to the caller terminal A.
F19: Call partner terminal A transmits to the transfer destination terminal C that the call between call partner terminal A and transfer source terminal B is transferred (Replaces: B). Since the URI of B is received at F8 to F14, the match with “B” in Invite replace: B is confirmed, and replace (transfer) is accepted (transfer request is accepted). Therefore, C does not accept a transfer request because the message source is A, but accepts a transfer request because the transfer source is B.
F20: A 200 OK response is returned from the transfer destination terminal C to the call partner terminal A.
F21: Notify (ACK) that the 200 OK response has been received from the call partner terminal A to the transfer destination terminal C. As a result, a call is established between the call partner terminal A and the transfer destination terminal C.
F22: Return that the call is disconnected from the transfer destination terminal C to the transfer source terminal B (BYE).
F23: A 200 OK response is returned from the transfer source terminal B to the transfer destination terminal C.
F24: The call partner terminal A transmits a NOTIFY request to the transfer source terminal B to notify that the call between the call partner terminal A and the transfer destination terminal C has been established.
F25: A 200 OK response is returned from the transfer source terminal B to the call partner terminal A.
F26: Return that the call is disconnected from the call partner terminal A to the transfer source terminal B (BYE).
F27: A 200 OK response is returned from the transfer source terminal B to the call partner terminal A.

  As a result, the call with the call destination terminal A is transferred to the transfer destination terminal C, and the call with the transfer source terminal B is disconnected from the transfer destination terminal C and the call destination terminal A. However, the processing may be terminated by F21 and the call with the transfer source terminal B may be continued from the call partner terminal A.

  In this embodiment, the sequence shown in FIG. 4-4 may be executed instead of the sequence shown in FIG. 4-3 described above. In this case, F1 to F15 in FIGS. 4-1 and 4-2 are the same as those in the case where the sequence shown in FIG. 4-3 is executed.

However, when the sequence shown in FIG. 4-4 is executed, more information is included in the two-dimensional code. Specifically, as shown in FIG.
F30: An instant message (Instant Messaging) is transmitted (MESSAGE). This instant message includes information for specifying the call partner terminal A. Then, the transfer destination terminal C identifies the call partner terminal A by analyzing the instant message.
F31: The transfer destination terminal C sends a 200 OK response as a response to receiving the instant message.

Information corresponding to these two processes is included in the two-dimensional code. Then, the transfer destination terminal C reads the two-dimensional code. Next, processing after reading the two-dimensional code will be described.
F32: The transfer destination terminal C requests the call partner terminal A to transfer the call between the call partner terminal A and the transfer source terminal B (INVITE Replaces: AB).
F33: The other party terminal A sends a 200 OK response as a response of INVITE Replaces: AB.
F34: The transfer destination terminal C returns an ACK to the call partner terminal A. A call can be made between the call partner terminal A and the transfer destination terminal C when the ACK arrives.
F35: Call partner terminal A transmits BYE to transfer source terminal B.
F36: The transfer source terminal B sends a 200 OK response as a response to receiving BYE. As a result, the call between the call partner terminal A and the transfer source terminal B ends.

  In the above description, the IP telephone exchange 400 operates as a proxy server. The IP telephone exchange 400 may transfer the call. In this case, processing up to F14 is performed, and then the two-dimensional code is read by the transfer destination terminal C.

  Based on the read two-dimensional code, the transfer destination terminal C obtains the session ID of the session between the call partner terminal A and the transfer source terminal B, the ID or URL of the transfer destination terminal C, the ID or URL of the call partner terminal A, IP It is transmitted to the telephone exchange 400.

  When the IP telephone exchange 400 receives the transfer request, it rewrites it. Specifically, based on the session ID of the session between the call partner terminal A and the transfer source terminal B, the ID or URL of the transfer source terminal B in this session is rewritten to the ID or URL of the call partner terminal A. Thereby, this session is continued at the call partner terminal A and the transfer destination terminal C.

  As described above, a specific example has been described. However, the detailed content itself regarding the sharing of the HTTP session and the SIP session is not an essential part of the present embodiment, but between the smart device 100 and the business handset unit 300 of the docking station. It is an essential part of the present embodiment that the proper use is performed smoothly.
