Specifically, the ringing state is a state in which a caller ID is displayed on the LCD and a ringing is being performed.

  The cordless telephone base unit 10 that has received a response to the incoming message from each of the cordless telephone handset 30, the mobile phone 40-1, and the mobile phone 40-2 transitions to a calling state (step 204). Although the cordless telephone base unit 10 and the mobile phone 40-2 have been described as directly exchanging messages, they may be exchanged via the SIP server 60 shown in FIG. 13 (the same applies to the following description). .

  FIG. 6 is an absence response sequence diagram of the cordless telephone system according to the first embodiment.

  The cordless telephone base unit 10 that has changed to the calling state is a user of the cordless telephone handset 30, the mobile phone 40-1, the mobile phone 40-2, and the cordless telephone base unit 10 itself even after a predetermined time has elapsed. When there is no response operation by (step 205), an answering machine is performed by an answering machine message shown below.

  Prior to the answering response, the cordless telephone base unit 10 first stops the incoming ringing of the cordless telephone base unit 10 itself, and performs the incoming ringing stop process for the cordless telephone handset 30 and the mobile phone 40-1 (Step S1). 206).

  For example, an internal message or the above-mentioned Q. This is performed by transmitting a message corresponding to an Info message conforming to the 931 specification including an information element indicating stoppage of incoming ringing. In addition, the process for stopping the ringing to the cellular phone 40-1 is performed by transmitting a CANCEL message in conformity with SIP, for example.

  Here, the characteristic of the cordless telephone system in the first embodiment is that, when an answering response is made, the incoming ringing is stopped for the mobile phone 40 outside the home, that is, the mobile phone 40-2. It is not. Details will be described later.

  Next, the cordless telephone base unit 10 performs a process of displaying an answering response to the cellular phone 40 in the home, that is, the cellular phone 40-1 (step 207).

  The process of displaying the absence response to the cellular phone 40-1 is performed, for example, by transmitting a NOTIFY message including an information element indicating the absence response in accordance with SIP.

  Finally, the cordless telephone base unit 10 controls the TAM unit 102 to start the recording / playback operation of the answering machine message. At the same time, the TAM unit 102, the cordless telephone base unit 10 itself, the fixed telephone network and the cordless telephone handset The voice path to 30 is connected to control so that the answering machine message can be heard (step 208). Then, the cordless telephone base unit 10 shifts to a state where the call is stopped and the answering machine message is being listened to. In step 206, instead of the CANCEL message, a NOTIFY message including an information element indicating stop of ringing and an answering display may be transmitted. Also, in the process of stopping ringing to the cordless telephone cordless handset 30, in addition to stopping ringing of ringing, for example, the start of listening to an answering machine message may be transmitted together (the same applies to the following description).

  FIG. 7 is a flowchart showing the absence response operation of the base unit of the cordless telephone system in the first embodiment.

  FIG. 7 explains in more detail the answering operation of the cordless telephone base unit 10 among the answering operations of the cordless telephone system described in FIG. 6.

  The cordless telephone base unit 10 that has transitioned to the calling state determines whether or not a predetermined time has elapsed (step 301). Here, the elapse of the predetermined time is not limited to a timer timeout (not shown), and includes, for example, a determination of whether or not it has been repeated four times if the incoming ringing is repeated four times. These conditions may be set in advance in the storage unit 103 as initial values of the apparatus, or may be set as appropriate by the user as parameters using the operation unit 105 or the like.

  In step 301, if the predetermined time has not elapsed, the process waits until the predetermined time elapses (step 301: No). If the predetermined time has elapsed (step 301: Yes), first, the ringing of the cordless telephone master 10 itself from the voice input / output unit 104 is stopped (step 302).

  The cordless telephone base unit 10 includes a registered slave unit stored in the storage unit 103 (that is, a mobile phone registered as a slave unit and further information on the outside / in-home about the mobile phone) The current state of the registered slave unit is referred to (step 303).

  If there is a mobile phone outside the home in the state of ringing (incoming ringing) in step 303 (step 303: No), the cordless telephone base unit 10 does not change the state of the mobile phone outside the home, that is, The process proceeds to step 307 while ringing the incoming call.

  If there is a cordless handset that is ringing (incoming call ringing) or a cellular phone in the house (step 303: Yes), the cordless telephone base unit 10 sends a message for stopping ringing to the cordless telephone set. This is transmitted via the wireless I / F unit 107 and the wireless LAN I / F unit 109, and the ringing of the slave unit or mobile phone is stopped (step 304).

  Then, the cordless telephone base unit 10 determines whether or not the registered handset that has stopped ringing is a mobile phone in the home (step 305), and if it is a mobile phone in the home (step 305: Yes), the home A message for causing the mobile phone to display that an answering response is being sent is transmitted via the wireless LAN I / F unit 109 to perform a process for displaying an answering response (step 306).

  Finally, the cordless telephone base unit 10 causes the TAM unit 102 to start recording / playback operation of the answering machine message, and also includes the TAM unit 102 and the cordless telephone base unit 10 itself, the TAM unit 102, the cordless telephone handset 30 and the TAM unit. The voice path between 102 and the fixed telephone network is connected (step 307).

  The answering machine message is, for example, a response message “can't answer the phone now” to be sent to the caller, and is also called OGM (Outgoing Message). The message left by the caller who heard the OGM playback message is also called ICM (Incoming Message).

  When the voice path between the TAM unit 102 and the cordless telephone base unit 10 itself is connected, an OGM playback message from the TAM unit 102 is issued from the voice input / output unit 104. When the voice path between the TAM unit 102 and the cordless telephone handset 30 is connected, an OGM playback message from the TAM part 102 is transmitted to the cordless telephone handset 30 via the cordless telephone handset wireless I / F unit 107. .

  When the voice path between the TAM unit 102 and the fixed telephone network is connected, the OGM playback message from the TAM unit 102 is transmitted to the caller connected to the public line via the NCU and modem unit 101. Also, an ICM recording message from the caller received via the NCU and modem unit 101 is recorded in the TAM unit 102.

  Then, the cordless telephone base unit 10 itself shifts to a state where the call is stopped (listening to the answering machine message).

  As described above, the cordless telephone base unit 10 performs the ringing stop process for the cordless telephone handset 30 and the cellular phone 40-1 in the house when making an answering response, but the cellular phone 40 outside the house. That is, the incoming call ringing stop process is not performed for the mobile phone 40-2.

  In the above description, in the process in which the cordless telephone base unit 10 in the calling state is changed to a state in which the calling is stopped (listening to the answering machine message), after the predetermined time elapses, the cordless telephone base unit 10 itself first receives an incoming call. Although the description has been made so that the ringing is stopped, the order in which the ringing is stopped or the message indicating that the answering operation is in progress is not limited to this. For example, the ringing of the cordless telephone base unit 10 itself may be stopped before the ringing of the cordless telephone base unit 10 itself is stopped. In step 304 to step 306, a message may be transmitted to each of the cordless telephone handset 30 and the mobile phone 40-2 without performing the determination in step 305 (the same applies to the following description).

<From absence to response to response from mobile information terminal outside the home>

(Third embodiment)
In the third embodiment, a cordless telephone base unit 10 as an example of a telephone device makes a call to a caller's telephone (hereinafter referred to as a “caller telephone”) that calls the cordless telephone base unit 10 to a transfer destination mobile phone. ) Will be described. As the mobile phone 40 for displaying the caller number, a smartphone (hereinafter referred to as “in-home smartphone”) 40-1 as a mobile phone in the house, a smartphone (hereinafter referred to as “ex-home smartphone”) as a mobile phone outside the house. 40-2 may be used, but here, a case of transferring to the outside smartphone 40-2 will be described.

  FIG. 13 is a schematic diagram showing an outline of a cordless telephone system according to the third embodiment. The cordless telephone system of the third embodiment has almost the same configuration as that of the first embodiment. About the same component as 1st Embodiment, the description is abbreviate | omitted by using the same code | symbol.

  In the cordless telephone system according to the third embodiment, the cordless telephone base unit 10 (also referred to as the CDL telephone base unit 10) has a transfer telephone function, and is connected to an external network such as the Internet. In addition, the mobile phone 40 is connected to the plurality of mobile phones 40 including the out-of-home smartphone 40-2 and the in-home smartphone 40-1 via the SIP server 60. The cordless telephone base unit 10 is connected to various fixed telephones 80 such as private homes and businesses through a fixed telephone network 70 including a telephone exchange.

  A SIP (Session Initiation Protocol) server 60 collects correspondences between a plurality of telephones such as the cordless telephone base unit 10 and the mobile telephone 40 (in-home smartphone 40-1 and out-of-home smartphone 40-2) and IP addresses, and these It plays the role of relaying SIP-compliant messages sent and received between them. In other words, the SIP server 60 has a relay function for establishing a communication path (session) between the cordless telephone base unit 10 and a transfer destination mobile phone (for example, the outside smartphone 40-2).

  When the cordless telephone base unit 10 receives an incoming call with a caller number attached from the fixed telephone 80-1, the cordless telephone base unit 10 shifts itself to the incoming call state and attaches its own telephone number (transfer telephone number) and the caller number. Then, the incoming call from the fixed telephone 80-1 is transferred to the outside smartphone 40-2 via the SIP server 60. When the cordless telephone base unit 10 receives an incoming call from the destination, the cordless telephone base unit 10 may forward the call to the outside smartphone 40-2 if there is no response even if it rings for a certain time, or automatic forwarding is set in advance. If the incoming call is received, the incoming call may be transferred to the outside smartphone 40-2 without ringing itself at the same time when the incoming call is received.

  In addition, a dedicated application for displaying a caller ID is installed in advance on the outside smartphone 40-2. When receiving the incoming call transfer from the cordless telephone base unit 10, the outside smartphone 40-2 displays that there is an incoming call on the screen of the LCD unit 146, and the caller number of the source fixed telephone 80-1 and Both the transfer telephone numbers of the cordless telephone base unit 10 of the transfer source are displayed. The caller ID is displayed as “03xxxyyyy”, for example. For example, “050...” Is displayed as the transfer telephone number.

  In addition, when the caller number is registered in the phone book data stored in the storage unit 143 of the outside smartphone 40-2, the outside smartphone 40-2 stores the phone book together with the caller number. Displays the name or name of the sender registered in. In addition, when the smart phone 40-2 outside a house displays a sender | caller's full name or name, it may not display a caller number and may display a caller number collectively.

  As a method for the cordless telephone base unit 10 to notify the outside smartphone 40-2 of the caller ID, various data communication paths such as information and voice between the cordless telephone base unit 10 and the outside smartphone 40-2 (in other words, Two methods are assumed: a notification method using an INVITE message transmitted when a session is established, and a notification method using a NOTIFY message. The INVITE message is a command used at the start of session establishment. On the other hand, the NOTIFY message is a command for notifying information indicating a specific state (for example, information on an incoming connection request), and is used regardless of the establishment of a session. Used before establishment. The method of notifying the caller number using these commands may be fixedly set to either one or may be arbitrarily selected and set by the user.

(Notification of caller ID by INVITE message)
FIG. 14 is a sequence diagram showing an operation of notifying the caller number from the cordless telephone base unit 10 to the outside smartphone 40-2 using the INVITE message when the session is established in the third embodiment. When the cordless telephone base unit 10 receives an incoming call from the fixed telephone 80-1 (see FIG. 13) as the caller telephone via the fixed telephone network 70, the cordless telephone base unit 10 rings and rings for a predetermined time. If there is no response, call transfer is started (step 901).

  The base unit control unit 110 of the cordless telephone base unit 10 refers to the storage unit 103 and confirms the presence / absence of the out-of-home smartphone 40-2 as the transfer destination mobile phone 40. In the storage unit 103, an out-of-home smartphone 40-2, an in-home smartphone 40-1, and a cordless telephone handset 30 are registered as the transfer destination handsets. Here, as the transfer destination, the out-of-home smartphone 40-2 is given priority here, but another telephone may be given priority. In addition, when the forwarding destination outside smartphone 40-2 does not respond after waiting for a certain time, the forwarding destination may be switched to the next in-home smartphone 40-1. The order of the transfer destinations can be arbitrarily set by the user's operation on the cordless telephone base unit 10 (for example, touch input operation when the LCD unit 106 is configured by a touch panel). If all the registered transfer destinations do not respond, it may return to the first transfer destination and search for the transfer destination again.

  Here, the specification of the message used for the incoming call transfer from the cordless telephone base unit 10 to the outside smartphone 40-2 is defined by “RFTC3261” formulated by IETF (Internet Engineering Task Force). “RFTC3261” describes specifications such as SIP-compliant INVITE messages.

  These messages are exchanged via the SIP server 60 by SIP_UA (User Agent: user agent) which is an application on the cordless telephone base unit 10 side and SIP_UA which is an application on the outside smartphone 40-2 side. The

  When the cordless telephone base unit 10 starts the incoming call transfer, the cordless telephone base unit 10 performs an incoming call process on the outside smartphone 40-2. As an incoming call process, the cordless telephone base unit 10 transmits an INVITE message to the outside smartphone 40-2 in accordance with SIP (step 902). The INVITE message transmitted to the outside smartphone 40-2 includes both the caller number and the transfer telephone number in addition to the destination of the external network (WAN).

  When the out-of-home smartphone 40-2 receives the incoming message and receives the INVITE message, it returns a response of “100 Trying” indicating the reception to the cordless telephone base unit 10. The outside smartphone 40-2 displays both the transfer telephone number and the caller number attached to the INVITE message on the screen of the LCD unit 146 (see FIG. 15).

  The out-of-home smartphone 40-2 starts ringing for calling the user (step 904), and transmits a “180 Ringing” response indicating the calling to the cordless telephone base unit 10 (step 905).

  The out-of-home smartphone 40-2 makes a response conforming to the SIP, and transitions to a calling state. Specifically, the ringing state is a state in which both the caller number and the forwarding telephone number are displayed on the LCD unit 146 and the incoming call is ringing.

  The cordless telephone base unit 10 transitions to a ringing state in which a response to the incoming message has been received from the outside smartphone 40-2. When the user responds by pressing the call button bn1 (see FIG. 15) in the operation unit 145 of the outside smartphone 40-2 (step 906), the outside smartphone 40-2 responds to the INVITE message. When the call button bn1 is pressed by the operation of the user who owns the mobile phone, a response “200 OK” indicating that a session with the cordless telephone base unit 10 can be established is sent via the SIP server 60 to the cordless telephone. It transmits to the main | base station 10 (step 907).

  When receiving the response “200 OK”, the cordless telephone base unit 10 returns “ACK” to the outside smartphone 40-2 (step 908), and establishes a session with the outside smartphone 40-2. As a result, the caller fixed telephone 80-1 connected to the cordless telephone base unit 10 and the outside smartphone 40-2 transition to a busy state (step 909).

  FIG. 15 is a diagram illustrating a screen of the LCD unit 146 of the external smartphone 40-2 displayed during ringing in the third embodiment. On this screen, both the caller number “03xxxyyyy” and the forwarding telephone number “050...” Are displayed. The display of the caller number and the transfer telephone number is performed in a period from when the outside smartphone 40-2 receives an INVITE message transmitted from the cordless telephone base unit 10 when a session is established until the user presses the call button bn1. . Note that the cordless telephone base unit 10 may display the caller number on its LCD unit 106 during this period. When the call is started, the function of the call button bn1 is changed to a call end button. The display of the caller ID and the transfer telephone number may be continued until the call is terminated.

  In addition, the outside smartphone 40-2 has a phone book function, and when the caller number is registered in the phone book data, the name or name of the caller corresponding to the caller number ( For example, “Mr. A”) is displayed together with the caller ID. When the phone book function is not installed or the caller number is not registered in the phone book data, the outside smartphone 40-2 simply displays both the caller number and the transfer phone number on the LCD unit. 146 is displayed on the screen.

  Thus, when the caller ID is notified by the INVITE message, since the caller ID is displayed on the outside smartphone 40-2 at the same time as receiving the incoming call transfer, the user can send the call displayed on the outside smartphone 40-2. By looking at the user number, it is possible to promptly confirm with ease who the caller is.

(Notification of caller ID by NOTIFY message)
FIG. 16 is a sequence diagram showing an operation of notifying a caller number from the cordless telephone base unit 10 to the outside smartphone 40-2 using a NOTIFY message when a session is established in the third embodiment. In this sequence, a NOTIFY message for notifying information on an incoming connection request is used. Note that the NOTIFY message can be transmitted even after the session is established, but FIG. 16 shows a case where the NOTIFY message is transmitted before the session is established, that is, before a call is made.

  Assume that the out-of-home smartphone 40-2 is ringing in the same procedure as steps 901 to 905 in FIG. However, the INVITE message transmitted from the cordless telephone base unit 10 to the outside smartphone 40-2 is accompanied by the transfer telephone number of the cordless telephone base unit 10, but not the caller number. When the INVITE message is received, the outside smartphone 40-2 displays only the transfer telephone number included in the INVITE message on the screen of the LCD unit 146.

  Subsequently, while the incoming call is ringing by the outside smartphone 40-2, the cordless telephone base unit 10 transmits a NOTIFY message to the outside smartphone 40-2 in accordance with the SIP, and notifies the connection request information during the incoming call ( Step 1001). This NOTIFY message includes a caller number as information of a connection request during an incoming call.

  When receiving the notification of information by the NOTIFY message, the outside smartphone 40-2 transmits a response of “200 OK” indicating the reception to the cordless telephone base unit 10 via the SIP server 60 (step 1002). The out-of-home smartphone 40-2 displays the caller number included in the NOTIFY message on the screen of the LCD unit 146.

  Thereafter, as in steps 906 to 909 in FIG. 14, when the user of the outside smartphone 40-2 presses the call button bn1, the outside smartphone 40-2 is connected to the fixed telephone 80- transferred by the cordless telephone base unit 10. 1, the user of the outside smartphone 40-2 and the user of the fixed telephone 80-1 connected to the cordless telephone base unit 10 start a call.

  FIG. 17 is a diagram illustrating a screen of the LCD unit 146 of the external smartphone 40-2 displayed during ringing in the third embodiment. Before receiving the NOTIFY message, only the forwarding telephone number is displayed on the screen of the LCD unit 146 of the outside smartphone 40-2. Thereafter, when the NOTIFY message is received, the caller number and the forwarding telephone number are displayed.

  In this way, even when the incoming call is ringing, the information displayed on the screen of the LCD unit 146 of the outside smartphone 40-2 changes before and after receiving the NOTIFY message. That is, the caller number and the transfer telephone number are displayed for a period from when the NOTIFY message transmitted from the cordless telephone base unit 10 is received until the user presses the call button bn1. The cordless telephone base unit 10 may display the caller number on the screen of its own LCD unit 106 during this period.

  When the call is started, the function of the call button bn1 is changed to the function of a call end button (not shown). The display of the caller number and the transfer telephone number may be continued until the call is terminated.

  Further, when the outside smartphone 40-2 has a phone book function and the caller number is registered in the phone book data, the name of the caller corresponding to the caller number “Mr. A” "Is displayed together with the caller ID. When the phone book function is not installed or the caller number is not registered in the phone book data, the outside smartphone 40-2 simply displays the caller number and the transfer phone number on the screen of the LCD unit 146. To display.

  Thus, when notifying the caller number using the NOTIFY message, the caller number is notified to the outside smartphone 40-2 by the NOTIFY message after the transfer telephone number is notified by the INVITE message. The caller ID can be confirmed after a short interval from the forwarding telephone number displayed on the screen of the outside smartphone 40-2.

  In addition, since the caller ID is not attached to the INVITE message, information included in the INVITE message can be reduced.

  Further, when the outside smartphone 40-2 is set not to receive the NOTIFY message, the caller ID is not displayed, but the communication processing load can be reduced accordingly. In this case, when the user of the off-site smartphone 40-2 wants to confirm the caller ID by looking at the forwarding telephone number, the user sends a SUBSCRIBE request meaning “request for status notification” to the cordless telephone base unit 10. The cordless telephone base unit 10 may transmit a NOTIFY message in response to this request.

  When the user of the outside smartphone 40-2 starts a call without receiving the caller number and wants to confirm the caller number of the other party who is calling, send a NOTIFY message to the cordless telephone base unit 10. The cordless telephone base unit 10 may send a NOTIFY message in response to this request. Thereby, it is also possible to confirm later the caller number of the other party who is talking.

  As described above, the cordless telephone base unit 10 of the present embodiment is connected to the fixed telephone network 70 and wirelessly connects to the outside smartphone 40-2 that is a mobile phone as a slave unit to the cordless telephone base unit 10 by wireless LANI. / F unit 109 (wireless communication unit) and parent device control for ringing the outside smartphone 40-2 when there is an incoming call from the fixed telephone 80-1 (caller telephone) via the fixed telephone network 70 Unit 110 (control unit). The base unit control unit 110 obtains information on the telephone number of the fixed telephone 80-1 and the telephone number of the cordless telephone base unit 10 before starting the call between the fixed telephone 80-1 and the external smartphone 40-2. -2 to display.

  As a result, the user can send the original external telephone (that is, the caller telephone) to be transferred to the outside smartphone 40-2 before the user who owns the outside smartphone 40-2 starts a call. You can know the person number. Therefore, the user can determine with confidence whether or not to start a call by looking at the caller number and the name (name) of the caller.

  Further, the cordless telephone master unit 10 uses the INVITE message when establishing a session between the cordless telephone master unit 10 and the outside smartphone 40-2 (in other words, at the start of forming a communication path). The telephone number (caller number) and the telephone number (forwarding telephone number) of the cordless telephone base unit 10 are transmitted to the outside smartphone 40-2.

  As a result, the cordless telephone base unit 10 simultaneously displays both the telephone number of the cordless telephone base unit 10 as a transfer telephone and the telephone number of the fixed telephone 80-1 on the outside smartphone 40-2 when a session is established. And the user can quickly determine whether or not to answer when the incoming call is received.

  Further, the cordless telephone base unit 10 sets the telephone number (caller number) of the fixed telephone 80-1 by the INVITE message at the start of session formation between the cordless telephone base unit 10 and the external smartphone 40-2. The information is transmitted to the smartphone 40-2, and then the information of the telephone number (caller number) of the fixed telephone 80-1 is transmitted to the outside smartphone 40-2 by a NOTIFY message.
