  An embodiment of the present invention will be described below.

  FIG. 1 is a schematic configuration diagram of an IP telephone system according to the present embodiment.

  As shown in the figure, the IP telephone system according to the present embodiment includes a plurality of fixed IP telephones 1-1 to 1-n (hereinafter also simply referred to as fixed IP telephone 1) and a plurality of wireless IP telephones 2-1 to 2-1. 2-m (hereinafter also simply referred to as a wireless IP telephone 2) and a SIP (Session Initiation Protocol) server 3 that accommodates the fixed IP telephone 1 and the wireless IP telephone 2.

  The fixed IP telephone 1 and the SIP server 3 are connected to a LAN 4, and the wireless IP telephone 2 is connected to the LAN 4 via a wireless access point (AP) 5. The LAN 4 is connected to the WAN 7 via a gateway (GW) 6. Further, a file server 8 is connected to the WAN 7.

  The fixed IP telephone 1 or the wireless IP telephone 2 is an IP telephone that can be used both in an office such as a company and at home. The fixed IP telephone 1 or the wireless IP telephone 2 has an IP telephone function, an electronic mail, a Web It has a software execution function such as a browser, a business application, and a game application, and a login / logout function for the software execution function. The fixed IP telephone 1 and the wireless IP telephone 2 permit the user to use the software execution function only when the login / logout function is in the login state, and when the user is in the logout state, the user uses the software execution function. To refuse.

  The types of login modes described in the present embodiment are an official login which is a login mode for using the fixed IP telephone 1 or the wireless IP telephone 2 in an office such as a company, and a fixed IP telephone 1 or a wireless IP at home. There are two types of private login, which is a login form for using the telephone 2.

  FIG. 2 is a sequence diagram for explaining a first operation example of the IP telephone system according to the present embodiment.

  Here, an example in which three fixed IP telephones 1-1 to 1-3 and one wireless IP telephone 2-1 are accommodated in the SIP server 3 is shown.

  The fixed IP phone 1-1 is logged in by the user NYC with private login (S101), and the fixed IP phone 1-2 is logged in with the official login by the user ITL (S102), and the fixed IP phone 1 -3 and the wireless IP telephone set 2-1 are in a logout state (S103, S104), and the user NYC suspends the work on the fixed IP telephone set 1-1, and the fixed IP telephone set 2-1 is connected to the wireless IP telephone set 2-1. This is an example when logging in with a login mode different from -1.

  When the wireless IP telephone set 2-1 receives a login operation (hereinafter referred to as an official login operation) from the user NYC using the account information (user ID and password) for official login (S105), the wireless IP telephone set 2-1 receives the account information for official login. Based on the user authentication. If the user authentication is successful, the wireless IP phone 2-1 permits the user NYC to log in officially (S106). Then, the wireless IP telephone 2-1 broadcasts login information including the name of the logged-in user (here, NYC) and the login form (here, official login) on the LAN 4 (S107).

  Next, the fixed IP telephone 1-2 in the official login state receives the login information broadcast from the wireless IP telephone 2-1, and the user name included in the login information is the fixed IP telephone 1. -2 determines whether or not it matches the name of the logged-in user (ITL in this case).

  Here, since the user name included in the login information is “NYC” and the user name logged in to the fixed IP telephone 1-2 is “ITL”, both user names do not match. Furthermore, since the login form included in the received login information is “official login” and the fixed IP telephone 1-2 is also “official login”, the login form matches (S108). At this time, the fixed IP telephone 1-2 displays that the user name (NYC in this case) included in the login information is using the wireless IP telephone 2-1 that is the transmission source of the login information ( S109).

  The fixed IP telephone set 1-1 in the private login state receives the login information broadcast from the wireless IP telephone set 2-1, as in the case of the fixed IP telephone 1-2, and is included in the login information. It is determined whether or not the current user name matches the name of the user who is logging in to the fixed IP telephone 1-1 (in this case, NYC).

  Here, since the user name included in the login information is “NYC” and the user name logged in to the fixed IP telephone 1-1 is also “NYC”, both user names match. Furthermore, since the login form included in the received login information is “official login” and the login form of the fixed IP telephone set 1-1 is “private login”, the login forms do not match (S110). At this time, the fixed IP telephone set 1-1 transmits an answering record setting request for making an incoming call to the fixed IP telephone set 1-1 to the SIP server 3 (S111). Then, in response to this, the SIP server 3 sets and starts an incoming call recording for the fixed IP telephone 1-1 (S112).

  Thereafter, the fixed IP phone 1-1 forcibly logs out the private login state (S113).

  FIG. 3 is a sequence diagram for explaining a second operation example of the IP telephone system according to the present embodiment.

  Here, an example in which three fixed IP telephones 1-1 to 1-3 and one wireless IP telephone 2-1 are accommodated in the SIP server 3 is shown.

  The fixed IP phone 1-1 is logged in by the user NYC with an official login (S201), and the fixed IP phone 1-2 is logged in with a private login by the user ITL (S202). -3 and the wireless IP telephone set 2-1 are in a logout state (S203, S204), and the user NYC interrupts the work for logging in to the fixed IP telephone set 1-1, and the fixed IP address is set to the wireless IP telephone set 2-1. The telephone 1-1 is an example of logging in with the same login form.

  When receiving the official login operation from the user (NYC) (S205), the wireless IP telephone set 2-1 performs user authentication based on the official login account information.

  If the user authentication is successful, the wireless IP phone 2-1 starts operation in the official login state (S206). Then, the wireless IP telephone set 2-1 broadcasts the login information including the name of the user who is logged in to the own device (here, NYC) and the logged-in login mode (here, official login) on the LAN 4 (S207). ).

  Next, the fixed IP telephone 1-2 receives the login information broadcast from the wireless IP telephone 2-1, and the user name included in the login information is logged in to the fixed IP telephone 1-2. It is determined whether or not it matches the user name (here, ITL).

  Here, since the user name included in the login information is “NYC” and the user name logged in to the fixed IP telephone 1-2 is “ITL”, both user names do not match. Furthermore, since the login form included in the received login information is “official login” and the login form of the fixed IP telephone 1-2 is “private login”, the login forms do not match. At this time, the received login information is discarded (S208).

  Similarly to the fixed IP telephone 1-2, when the fixed IP telephone 1-1 receives the login information broadcast from the wireless IP telephone 2-1, the user name included in the login information is fixed IP. It is determined whether or not it matches the name of the user who is logged in to the telephone 1-1 (here, NYC).

  Here, since the user name included in the login information is “NYC” and the user name logged in to the fixed IP telephone 1-1 is also “NYC”, both user names match. Furthermore, since the login form included in the received login information is “official login” and the login form of the fixed IP telephone 1-2 is “official login”, the login form also matches (S209). At this time, the fixed IP phone 1-1 generates a file download history list of files downloaded during operation in the current login mode (S210), and transmits the file download history list to the wireless IP phone 2-1 (S211). ).

  The wireless IP telephone set 2-1 that has received the file download history list compares the received file download history list with the file download history list stored in its own communication device (S212). Thereafter, an undownloaded file is extracted from the file download history list stored in the communication apparatus, and the file is downloaded to the file server 8 (S213, S214). When the file download is completed, the file download history list in the own device is updated (S215).

  On the other hand, after transmitting the file download history list, the fixed IP phone 1-1 sends an incoming call transfer setting request for transferring the incoming call to the fixed IP phone 1-1 to the wireless IP phone 1-2 to the SIP server 3. Transmit (S216). In response to this, the SIP server 3 sets and starts the incoming call transfer to the fixed IP telephone 1-1 (S217).

  Thereafter, the fixed IP telephone set 1-1 forcibly logs out the official login state (S218).

  FIG. 4 is a functional configuration diagram of the fixed IP telephone 1 or the wireless IP telephone 2.

  As shown in the figure, the fixed IP telephone 1 or the wireless IP telephone 2 includes a communication interface unit 101, a man-machine interface unit 102, an IP phone processing unit 103, a software execution unit 104, a login / logout management unit 105, , Login information transmission / reception unit 106, login destination notification unit 107, forced logout control unit 108, answering / call forwarding setting request unit 109, file download history list storage unit 110, file download management unit 111, download A history list transmission / reception unit 112;

  A user ID field 1053 and a password field 1054 are registered for each login mode field 1052.

  If the login / logout management unit 105 receives a login operation from the user via the man-machine interface unit 102 when the field 1055 is logging out, the account information (user ID and password) received by the login operation is Of any of the login forms registered in the field 1052, whether the user ID is registered in the field 1053 and the password registered in the field 1054 is determined, and the login form is specified. When the login form is specified, user authentication is performed using the account information. If the user authentication is successful, the connection between the man-machine interface unit 102 and the software execution unit 104 is validated, and the software execution unit 104 by the user Allow use (login). At that time, the field 1055 is changed during login. The login / logout management unit 105 receives a forced logout instruction from the forced logout control unit 108 (to be described later) when a logout operation is accepted from the user via the man-machine interface unit 102 when the field 1055 is logged in. If accepted, the connection between the man-machine interface unit 102 and the software execution unit 104 is invalidated, and thereafter the use of the software execution unit 104 by the user is refused (logout). At that time, the field 1055 is changed during logout.

  In accordance with an instruction from the login / logout management unit 105, the login information transmission / reception unit 106 generates login information including the name of the user who is logged in to the own IP telephone and the login type being logged in, and this login information is stored on the LAN 4. Send a report. The login information transmission / reception unit 106 refers to the user management table 1050 of the login / logout management unit 105 when receiving login information from another fixed IP telephone 1 or wireless IP telephone 2 via the communication interface unit 101. The login form in which the field 1055 is logged in is specified from the field 1052, and the corresponding user name is specified from the field 1051. Thereafter, it is determined whether or not the user name included in the received login information is the same as the user name specified from the field 1051. Further, it is determined whether or not the login form included in the login information is the same as the login form specified from the field 1052.

  When the user name included in the login information is the same as the user name logged in to the IP phone, the login information transmitting / receiving unit 106 notifies the forced logoff control unit 108 of the login information.

  Also, when the user name included in the login information is not the same as the user name logged in to the own IP telephone, and the login form included in the login information is the same as the login form logged into the own IP telephone The login information transmitting / receiving unit 106 notifies the login destination notifying unit 107 of the login information.

  When the login information is received from the login information transmission / reception unit 106, the login destination notifying unit 107 has the user name included in the login information as the IP telephone (fixed IP telephone 1 or wireless IP telephone) that is the transmission source of the login information. 2) is displayed on the man-machine interface unit 102.

  When the login information is received from the login information transmission / reception unit 106, the forced logout control unit 108 instructs the login / logout management unit 105 to forcibly log out the user name included in the login information and The information is notified to the recorded message / incoming transfer setting requesting unit 109 and the file download managing unit 111.

  When the answering / call transfer setting requesting unit 109 receives logon information from the forced logout control unit 108, the other fixed IP telephone 1 or wireless IP telephone 2 that is the transmission source of the logoff information receives an incoming call to the own IP telephone. An incoming call transfer setting request for transferring the incoming call is generated, and this incoming call transfer setting request is transmitted to the SIP server 3 via the communication interface unit 101.

  When the answering / call transfer setting requesting unit 109 further receives the login information from the forced logout control unit 108, the other IP phone 1 or the wireless IP phone 2 that is the transmission source of the logout information is sent to the own IP phone. An answering machine setting request for answering an incoming call is generated, and the answering machine setting request is transmitted to the SIP server 3 via the communication interface unit 101.

  The file download history list storage unit 110 has a download history table 1101 for registering the download history of files downloaded during login for each user. Next, the download history table 1101 will be described with reference to FIG.

  When the login / logout management unit 105 receives a login operation from the user via the man-machine interface unit 102 (YES in S701), the login / logout management unit 105 performs user authentication based on the account information received from the user via this login operation (S702). ). Specifically, it is determined whether the account information received from the user is registered in advance as the account information of the user who is permitted to log in. If the user authentication fails (NO in S703), predetermined error processing such as displaying the fact on the man-machine interface unit 102 is performed, and then the process returns to S701 to wait for a new login operation.

  On the other hand, when the user authentication is successful (YES in S703), the login / logout management unit 105 determines the logon form and performs login processing (S704). As a result, the user can use the software execution unit 104 for each logon mode.

  Next, the login / logout management unit 105 instructs the login information transmission / reception unit 106 to transmit login information including the name of the user who is logged in to the IP phone and the current login form. In response to this, the login information transmitting / receiving unit 106 generates login information including the name of the logged-in user and the current login form, and broadcasts the login information on the LAN 4 (S705).

  Next, the file download history list transmission / reception unit 112 receives other logins from the login / logout management unit 105 until a time-out occurs after a predetermined time elapses (S710). It waits for a file download history list including the login form of the logged-in user and the user name corresponding to the login form to be sent from the fixed IP telephone 1 or the wireless IP telephone 2 (S706). If the file download history list transmission / reception unit 111 receives a file download history list including a login form that matches the current login form of the logged-in user and a user name corresponding to the login form (YES in S706). The file download history list is transferred to the file download management unit 111.

  In response to this, the file download management unit 111 compares the file download history list with the file download history table 1101 stored in the own IP telephone (S707), and downloads the file of the communication device to the received file download history list. It is specified whether there is a file download history that is not stored in the record 1102 of the history table 1101 (S708).

  Specifically, among the records 1102 included in the received file download history list, records that are not stored in the records 1102 registered in the download history table 1101 stored in the communication device. 1102 is extracted. Then, the file download management unit 111 controls the software execution unit 104 to access the address registered in the subfield 11036 of the field 1103 of the extracted record 1102, and to access the subfield of the field 1103 of the extracted record 1102 A file specified by the file name, file type, and file size registered in 11031 to 11033 is downloaded (S709).

  The file download management unit 111 monitors the access to the file server 8 by the software execution unit 104, and if the software execution unit 104 downloads a file through the communication interface unit 101 by a user operation. Based on the downloaded file (YES in S711), the file download history table 1101 stored in the file download history list storage unit 110 in association with the user name 1100 of the logged-in user is updated (S712). Specifically, a new record 1102 is added to the file download history table 1101, and the file name, file type, file size, download date and time of the downloaded file are displayed in the subfields 11031 to 11037 of the field 1103 of this record 1102. Register the file download source address, the account information for downloading the file, and the login form at the time of download.
