  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 and an ASP (Application Service Provider) server 9 are connected to the WAN 7.

  In addition to the IP telephone function, the fixed IP telephone 1 and the wireless IP telephone 2 have software execution functions such as e-mails, Web browsers, business applications, game applications, etc., and logon / logoff functions for the software execution functions. Yes. The fixed IP telephone 1 and the wireless IP telephone 2 allow the user to use the software execution function only when the user is in the logon state by the logon / logoff function, and in the logoff state, the user uses the software execution function. To refuse.

  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.

  User A is logged on to fixed IP telephone 1-1 (S101), user B is logged on to fixed IP telephone 1-3 (S102), and fixed IP telephone 1-2 and wireless IP telephone 2-1 is in a logoff state (S103, S104).

  When the fixed IP telephone 1-1 accesses the file server 8 according to the instruction from the user A and downloads a desired file (data file or program file) from the file server 8 (S105), the attribute information of this file The address information of the file server 8 that is the download source is registered in association with the user ID of the user A (S106). If account information for accessing the file server 8 is necessary, this account information is included in the address information.

  Next, user A suspends work due to various work interruption reasons including unexpected circumstances such as visitor, extraordinary meeting, telephone response, etc., and then uses it before work interruption due to reasons such as changing the work place. It is assumed that the work is resumed with the wireless IP telephone 2-1 instead of the fixed IP telephone 1-1.

  When receiving the logon operation from the user A (S107), the wireless IP telephone set 2-1 performs user authentication based on the account information (user ID and password) received from the user A through the logon operation (S108). If the user authentication is successful, the user A is permitted to log on (S109). Then, the wireless IP telephone 2-1 broadcasts the logon information including the user ID of the user A who has logged on to the wireless IP telephone 2-1 on the LAN 4 (S110).

  Next, the fixed IP telephone 1-3 in the logon state receives the logon information broadcast from the wireless IP telephone 2-1, and the user ID included in the logon information is the fixed IP telephone 1-3. It is determined whether or not it matches the user ID of the user B who is currently logged on. Here, since the user ID included in the logon information is that of the user A and the user who is logged on to the fixed IP telephone 1-3 is the user B, both user IDs do not match. In this case, the fixed IP telephone 1-3 displays that the user A specified by the user ID included in the logon information is using the wireless IP telephone 2-1 that is the transmission source of the logon information. (S111).

  Similarly to the fixed IP telephone 1-3, the fixed IP telephone 1-1 in the logon state receives the logon information broadcast from the wireless IP telephone 2-1, and is included in this logon information. It is determined whether or not the user ID matches the user ID of user A who is logged on to fixed IP telephone set 1-1. Here, since the user ID included in the logon information is that of the user A and the user who is logged on to the fixed IP telephone 1-1 is the user A, both user IDs match. In this case, the fixed IP phone 1-1 executes the forced logoff of the user A (S112). Then, the fixed IP telephone set 1-1 transmits an incoming call transfer setting request for transferring the incoming call to the fixed IP telephone set 1-1 to the wireless IP telephone set 2-1 that is the transmission source of the logon information, to the SIP server 3. (S113). In response to this, the SIP server 3 sets the transfer of the incoming call to the fixed IP telephone 1-1 to the wireless IP telephone 2-1 (S114).

  In addition, the fixed IP phone 1-1 creates acquisition list information including the user ID of the user A who has been forcibly logged off, and attribute information and address information of each file registered in association with the user ID ( In step S115, the acquisition list information is transmitted to the wireless IP telephone set 2-1 that is the transmission source of the logon information (step S116).

  Next, when the wireless IP phone 2-1 in the logon state receives the acquisition list information including the user ID of the user A who is logged on to the wireless IP phone 2-1, the attribute information of the file included in this acquisition list information Based on the above, a file not downloaded by the user A to the wireless IP telephone 2-1 is extracted from the files downloaded by the user A to the fixed IP telephone 1-1 (S117). Specifically, from the acquisition list information, attribute information other than the attribute information of the file registered in the wireless IP telephone set 2-1 in association with the user ID of the user A and the address associated with this attribute information Get information. Then, the wireless IP phone 2-1 accesses the file server 8 specified by the acquired address information, and downloads the file specified by the acquired attribute information from the file server 8 (S118). At this time, if the account information is included in the address information, the file server 8 is accessed using this account information. Note that a list of attribute information acquired from the acquired list information may be displayed, and the user A may be made to select attribute information of a file to be downloaded to the wireless IP telephone set 2-1 from the list.

  FIG. 3 is a sequence diagram for explaining a second operation example of the IP telephone system according to the present embodiment. As in FIG. 2, 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.

  In this state, the fixed IP telephone 1-1 accesses the ASP server 9 according to the instruction from the user A and uses the application software function provided by the ASP server 9 (S125).

  Now, user A has interrupted work for various reasons including sudden events such as visitors, extraordinary meetings, telephone correspondence, etc., and then used it before the work was interrupted for reasons such as changing the work location. It is assumed that the work is resumed not with the fixed IP telephone set 1-1 but with the wireless IP telephone set 2-1.

  When receiving the logon operation from the user A (S126), the wireless IP phone 2-1 performs user authentication based on the account information (user ID and password) received from the user A through the logon operation (S127). If the user authentication is successful, the user A is permitted to log on (S128). Then, the wireless IP phone 2-1 broadcasts the logon information including the user ID of the user A who has logged on to the wireless IP phone 2-1, over the LAN 4 (S129).

  Next, the fixed IP telephone 1-3 in the logon state receives the logon information broadcast from the wireless IP telephone 2-1, and the user ID included in the logon information is the fixed IP telephone 1-3. It is determined whether or not it matches the user ID of the user B who is currently logged on. Here, since the user ID included in the logon information is that of the user A and the user who is logged on to the fixed IP telephone 1-3 is the user B, both user IDs do not match. In this case, the fixed IP telephone 1-3 displays that the user A specified by the user ID included in the logon information is using the wireless IP telephone 2-1 that is the transmission source of the logon information. (S130).

  Similarly to the fixed IP telephone 1-3, the fixed IP telephone 1-1 in the logon state receives the logon information broadcast from the wireless IP telephone 2-1, and is included in this logon information. It is determined whether or not the user ID matches the user ID of user A who is logged on to fixed IP telephone set 1-1. Here, since the user ID included in the logon information is that of the user A and the user who is logged on to the fixed IP telephone 1-1 is the user A, both user IDs match. In this case, the fixed IP phone 1-1 creates access information including the user ID of the user A who is logged on and the address information of the ASP server 9 being accessed (S131). If account information for accessing the ASP server 9 is necessary, this account information is included in the address information. Then, the fixed IP phone 1-1 executes the forced logoff of the user A (S132).

  Next, the fixed IP telephone set 1-1 transmits an incoming call transfer setting request for transferring the incoming call to the fixed IP telephone set 1-1 to the wireless IP telephone set 2-1 that is the transmission source of the logon information, to the SIP server 3. (S133). In response to this, the SIP server 3 sets the transfer of the incoming call to the fixed IP telephone 1-1 to the wireless IP telephone 2-1 (S134).

  The fixed IP telephone set 1-1 transmits the created access information to the wireless IP telephone set 2-1 that is the transmission source of the logon information (S135).

  Next, when the wireless IP phone 2-1 in the logon state receives the access information including the user ID of the user A who is logged on to the wireless IP phone 2-1, the wireless IP phone 2-1 is identified by the address information included in the access information. The ASP server 9 is accessed (S137). Here, if the account information is included in the access information, the ASP server 9 is accessed using this account information. Note that the wireless IP telephone set 2-1 may ask the user A for approval before accessing the ASP server 9.

  Next, details of fixed IP telephone 1 and wireless IP telephone 2 constituting the IP telephone system according to the present embodiment will be described. Note that since a general SIP server can be used as the SIP server 3, detailed description thereof is omitted.

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 use of the software execution unit 104 by the user is permitted (logon). Further, when the logon / logoff management unit 105 receives a logoff operation from the user via the man-machine interface unit 102 in the logon state or when a forced logoff instruction is received from the forced logoff control unit 108 described later, The connection between the 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 (logoff).

  The logon information transmission / reception unit 106 generates logon information including the user ID of the logged-on user according to an instruction from the logon / logoff management unit 105, and broadcasts the logon information on the LAN 4. Further, when the logon information transmission / reception unit 106 receives logon information from another fixed IP telephone 1 or the wireless IP telephone 2 via the communication interface unit 101, the logon information transmission / reception unit 106 refers to the logon / logoff management unit 105 to obtain the logon information. It is determined whether or not the included user ID matches the user ID of the user who is logged on to the own IP phone. If both user IDs match, this logon information is notified to the forced logoff control unit 108, and if both user IDs do not match, this logon information is notified to the logon destination notification unit 107.

  When the logon information is received from the logon information transmitting / receiving unit 106, the logon destination notifying unit 107 determines that the user identified by the user ID included in the logon information is the IP telephone (fixed IP telephone) that is the transmission source of the logon information. 1 or the wireless IP telephone 2) is displayed on the man-machine interface unit 102.

  When the logon information is received from the logon information transmission / reception unit 106, the forced logoff control unit 108 instructs the logon / logoff management unit 105 to perform forced logoff of the user specified by the user ID included in the logon information. At the same time, this logon information is notified to the incoming call transfer request unit 109, the file acquisition management unit 111, and the access management unit 113.

  When the incoming call transfer request unit 109 receives logon information from the forced logoff control unit 108, the incoming call transfer request unit 109 transfers the incoming call to the own IP phone to the other fixed IP telephone 1 or wireless IP telephone 2 that is the transmission source of the logoff information. The incoming call transfer setting request is generated, and the incoming call transfer setting request is transmitted to the SIP server 3 via the communication interface unit 101.

  The acquisition list information storage unit 110 stores attribute information and address information of a file downloaded during logon for each user.

  FIG. 5 is a diagram schematically illustrating an example of registered contents in the acquisition list information storage unit 110.

  As shown in the figure, the acquisition list information storage unit 110 stores a table 1101 of acquisition list information in association with the user ID 1100 of the target user for each user who can log on to the own IP telephone. Registered in the table 1101 is a record 1102 of attribute information and address information of the file downloaded by the target user during logon. The record 1102 includes a field 1103 for registering file attribute information, and a field 1104 for registering file download source address information. The field 1103 includes a subfield 11031 for registering a file name, a subfield 11032 for registering a file type, a subfield 11033 for registering a file size, and a subfield 11034 for registering a file download date / time. The field 1104 has a subfield 11041 for registering the file download source address (URL) and a subfield 11042 for registering the account information when the account information is required for downloading the file.

  The file acquisition management unit 111 monitors the access to the file server 8 or the like by the software execution unit 104, and if the software execution unit 104 downloads a file via the communication interface unit 101, the software execution unit A table 1101 associated with the user ID 1100 of the user who is logged on to 104 is identified from the acquisition list information storage unit 110, and a new record 1102 is added to this table 1101. Then, the file name, file type, file size, and download date and time of the downloaded file are registered in the subfields 11031 to 11034 of the field 1103 of the added record 1102, and the subfields 11041 and 11042 of the field 1104 are registered. Register the file download source address and the account information if download information is required.

  Further, when the log acquisition information is received from the forced logoff control unit 108, the file acquisition management unit 111 stores the user ID included in the logon information and the acquisition list information storage unit 110 in association with the user ID. Acquisition list information including a record 1102 registered in the stored table 1101 and a record 1102 in which the date and time after logon is registered in the subfield 11034 is generated. Then, this acquisition list information is notified to the acquisition list information transmitting / receiving unit 112 together with the transmission source address of the logon information.

  Further, when the acquisition list information is received from the acquisition list information transmitting / receiving unit 112, the file acquisition management unit 111 is stored in the acquisition list information storage unit 110 in association with the user ID included in the acquisition list information. The table 1101 is specified. Then, among the records 1102 included in the acquisition list information, any of the records 1102 registered in the identified table 1101 includes the file names and files registered in the subfields 11031 to 11033 of the field 1103. A record 1102 whose type and file size do not match is extracted. Then, the file acquisition management unit 111 controls the software execution unit 104 to access the address registered in the subfield 11041 of the field 1104 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 from this access destination. If the account information is registered in the subfield 11042 of the field 1104 of the extracted record 1102, the account information is used to set the address registered in the subfield 11041 of the field 1104 of the extracted record 1102. Access and download the file.

  When the acquisition list information transmission / reception unit 112 receives the acquisition list information from the file acquisition management unit 111 together with the transmission source address of the logon information, the acquisition list information transmission / reception unit 112 receives another fixed IP specified by the transmission source address via the communication interface unit 101. The acquisition list information is transmitted to the telephone 1 or the wireless IP telephone 2.

  Further, the acquisition list information transmission / reception unit 112 receives the acquisition list information including the user ID of the user who is logged on to the software execution unit 104 from another fixed IP telephone 1 or wireless IP telephone 2 via the communication interface unit 101. If so, the acquisition list information is passed to the file acquisition management unit 111.

  The access management unit 113 monitors the access to the ASP server 9 or the like by the software execution unit 104, and when the logon information is received from the forced logoff control unit 108, there is an ASP server 9 or the like being accessed. The access information including the user ID included in the logon information and the address information of the ASP server 9 or the like being accessed is generated. Here, when account information is necessary for accessing the ASP server 9 or the like being accessed, the account information is included in the address information in addition to the address of the ASP server 9 or the like being accessed. Then, this access information is notified to the access information transmitting / receiving unit 114 together with the transmission source address of the logon information.

  Further, when access information is received from the access information transmission / reception unit 114, the access management unit 113 controls the software execution unit 104 to access an address included in the address information in the access information. Here, if the account information is included in the address information, access is made using this account information.

  When the access information transmission / reception unit 114 receives the access information from the access management unit 113 together with the transmission source address of the logon information, the access information transmission / reception unit 114, via the communication interface unit 101, receives another fixed IP telephone 1 specified by the transmission source address or This access information is transmitted to the wireless IP phone 2.

For example, this access information is passed to the access management unit 113.

  FIG. 6 is a flowchart for explaining operations of the fixed IP telephone 1 and the wireless IP telephone 2.

  When the logon / logoff management unit 105 receives a logon operation from the user via the man-machine interface unit 102 (YES in S200), the logon / logoff management unit 105 performs user authentication based on the account information received from the user via this logon operation (S201). ). 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 on. If the user authentication fails (NO in S202), predetermined error processing such as displaying the fact on the man-machine interface unit 102 is performed, and then the process returns to S200 to wait for a new logon operation.

  On the other hand, when the user authentication is successful (YES in S202), the logon / logoff management unit 105 permits the user to log on (S203). As a result, the user can use the software execution unit 104.

  Next, the logon / logoff management unit 105 notifies the logon information transmission / reception unit 106 of the user ID of the logged-on user and instructs transmission of the logon information. In response to this, the logon information transmission / reception unit 106 generates logon information including the user ID of the logged-on user, and broadcasts the logon information on the LAN 4 (S204).

  Next, the acquisition list information transmission / reception unit 112 performs other fixed operations via the communication interface unit 101 during a period from when the logon of the user is permitted by the logon / logoff management unit 105 to when a time-out occurs after a predetermined time elapses (S211). It waits for acquisition list information including the user ID of the logged-on user from IP telephone 1 or wireless IP telephone 2 (S205). If the acquisition list information transmission / reception unit 112 receives the acquisition list information including the user ID of the logged-on user (YES in S205), the acquisition list information transmission / reception unit 112 passes the acquisition list information to the file acquisition management unit 111.

  In response to this, the file acquisition management unit 111 uses the acquisition list information, and from the files downloaded to the other fixed IP telephone 1 or the wireless IP telephone 2 used by the logged-on user before logging on. Then, an undownloaded file is specified in the own IP telephone (S206). Specifically, the table 1101 associated with the logged-on user ID and stored in the acquisition list information storage unit 110 is specified, and the specified table is selected from among the records 1102 included in the acquisition list information. For each of the records 1102 registered in 1101, a record 1102 whose file name, file type, and file size registered in the subfields 11031 to 11033 of the field 1103 do not match is extracted.

  Next, the file acquisition management unit 111 controls the software execution unit 104 to access the address registered in the subfield 11041 of the field 1104 of the extracted record 1102 and to access the sub-field of the field 1103 of the extracted record 1102. The file specified by the file name, file type, and file size registered in the fields 11031 to 11033 is downloaded from this access destination (S207). If the account information is registered in the subfield 11042 of the field 1104 of the extracted record 1102, the account information is used to set the address registered in the subfield 11041 of the field 1104 of the extracted record 1102. Let them access and download the file.

  Similarly, the access information transmission / reception unit 114 receives another fixed IP via the communication interface unit 101 from the time when the logon of the user is permitted by the logon / logoff management unit 105 to the time-out due to the elapse of a predetermined time (S211). It waits for access information including the user ID of the logged-on user from the telephone 1 or the wireless IP telephone 2 (S209). When the access information transmission / reception unit 114 receives access information including the user ID of the logged-on user (YES in S209), the access information transmission / reception unit 114 passes this access information to the access management unit 113. In response to this, the access management unit 113 controls the software execution unit 104 to access the address included in the address information in the access information (S210). Here, if the account information is included in the address information, access is made using this account information.

  The file acquisition management unit 111 monitors the access to the file server 8 or the like by the software execution unit 104, and if the software execution unit 104 downloads a file via the communication interface unit 101 (S212). YES) Based on the downloaded file, the table 1101 associated with the user ID 1100 of the logged-on user and stored in the acquisition list information storage unit 110 is updated (S213). Specifically, a new record 1102 is added to this table 1101, and the file name, file type, file size, and download date and time of the downloaded file are registered in the subfields 11031 to 11034 of the field 1103 of this record 1102 At the same time, in the subfields 11041 and 11042 of the field 1104, the address of the file download source and the account information when the download requires the account information are registered.

  If the logon information transmission / reception unit 106 receives logon information from another fixed IP telephone 1 or wireless IP telephone 2 via the communication interface unit 101 (YES in S214), the logon information transmission / reception unit 106 refers to the logon / logoff management unit 105.

  Next, the incoming call transfer request unit 109 transfers incoming calls to the IP telephone to another fixed IP telephone 1 or wireless IP telephone 2 that is the transmission source of the logoff information received from the forced logoff control unit 108. A request is generated, and this incoming call transfer setting request is transmitted to the SIP server 3 via the communication interface unit 101 (S217).

  Next, the file acquisition management unit 111 determines whether the user specified by the user ID included in the logon information received from the forced logoff control unit 108 has downloaded the file during logon (S218). Specifically, a record 1102 in which the date and time after logon is registered in the subfield 11034 of the field 1103 is registered in the table 1101 stored in the acquisition list information storage unit 110 in association with the user ID. It is determined that the file was downloaded during logon. If a file is downloaded during logon (YES in S218), the user ID associated with this table 1101 and the record 1102 registered in this table 1101 are displayed after logon. Acquisition list information including the record 1102 registered in the subfield 11034 of the date 1103 is generated. Then, this acquisition list information is notified to the acquisition list information transmitting / receiving unit 112 together with the transmission source address of the logon information. In response to this, the acquisition list information transmitting / receiving unit 112 transmits the acquisition list information to the other fixed IP telephone 1 or the wireless IP telephone 2 specified by the transmission source address via the communication interface unit 101 ( S219).

  Next, the access management unit 113 follows the user instruction specified by the user ID included in the logon information received from the forced logoff control unit 108 and determines whether or not the ASP server 9 or the like was being accessed until the forced logoff was performed. Judgment is made (S220). If the ASP server 9 or the like is being accessed (YES in S220), access information including this user ID and address information of the ASP server 9 or the like being accessed is generated, and this access information is generated. Is sent to the access information transmission / reception unit 114 together with the transmission source address of the logon information. In response to this, the access information transmitting / receiving unit 114 transmits the access information to the other fixed IP telephone 1 or the wireless IP telephone 2 specified by the transmission source address via the communication interface unit 101 (S221). . Then, it returns to S200 and waits for a new logon operation.

  When the log-on / log-off management unit 105 receives a log-off operation from the user via the man-machine interface unit 102 during user log-on (YES in S223), the log-on / log-off management unit 105 executes the log-off of the user (S224). This makes it impossible for the user to use the software execution unit 104. Then, it returns to S200 and waits for a new logon operation.
