  FIG. 2 is a block diagram illustrating a functional configuration of the mobile communication terminals 31, 32, and 33. Note that FIG. 2 shows a functional configuration of a part related to communication control, and other functional configurations are omitted because they are not directly related to the present invention. Moreover, since the mobile communication terminals 31, 32, and 33 have the same configuration, the mobile communication terminal 31 will be described when it is not necessary to distinguish between them. In the following description, the reference numerals of the parts of the mobile communication terminals 31, 32, and 33 are the same for the sake of simplicity.

  Each of the mobile communication terminals 31, 32, and 33 includes a communication control unit 51, a WAN communication unit 53, a LAN communication unit 54, an intra connection determination unit 55, a business data processing unit 57, and a private data processing unit 58.

  The WAN communication unit 53 as the first communication unit is connected to the carrier network 5 as the first communication network using a communication method such as 3G or LTE, and performs wide-area communication. Note that the WAN communication units 53 of the mobile communication terminals 32 and 33 are also connected to the carrier network 5 using a communication method such as 3G or LTE to perform wide-area communication. In this embodiment, 3G or LTE is exemplified as a wide-area communication method. Other than this, WiMAX (registered trademark) (Worldwide Interoperability for Microwave Access), PHS (Personal Handy-phone System), 2G or 4G Other cellular communication systems may be used and are not particularly limited.

  A LAN communication unit 54 as a second communication unit is connected to the intranet 3 through the access point 21 using a wireless LAN (WLAN), and performs narrow-area communication. Note that the LAN communication unit of the mobile communication terminal 33 uses the wireless LAN 8 to connect to the access network 7 as the second communication network via the access point 25 and perform narrow-area communication. Further, in this embodiment, a wireless LAN is exemplified as a narrow communication method, but Bluetooth (registered trademark), WiFi-Direct, or Ethernet (registered trademark) may be used, and is not particularly limited.

The intra connection information is the subnet address or GW (Gateway) address of the intranet 3, and is the ESSID (Extended Service Set ID) or BSSID (Basic Service Set ID) of the access points 21 and 25.

  The business data processing unit 57 is an application that processes (including generation, editing, and deletion) communication data (business data) for business use. The business data is data such as a user schedule or an address book, for example. Further, although the business data processing unit 57 has been described as being configurable using an application, it may be an OS (Operating System) instead of an application.

  The private data processing unit 58 is an application that processes (including generation, editing, and deletion) communication data (private data) for private use. Private data is, for example, data such as a photograph image taken by an individual user or a catalog of individual user use. Further, although the private data processing unit 58 has been described as being configurable using an application, it may be an OS (operating system) instead of an application.

  In FIG. 2, the business data processing unit 57 and the private data processing unit 58 are provided as separate functional configurations, but the business data processing unit 57 and the private data processing unit 58 are grouped as a data processing unit 60. Anyway. The same applies to FIG. 6 described later.

  The communication control part 51 has the communication selection memory | storage part 52 which stores the communication selection table 52a, and controls communication of the portable communication terminal 31 according to the content described in the communication selection table 52a.

  FIG. 3 is a diagram showing the contents of the communication selection table 52a. The communication selection table 52a shows a communication method for business use and a communication method for private use corresponding to the intra connection information.

  Specifically, when the LAN communication unit 54 is connected to the intranet 3 by the wireless LAN 4 in the mobile communication terminal 31, the following communication path is selected. The mobile communication terminal 31 directly communicates with the Web server 12 connected to the Internet 9 via the proxy server 15 using the LAN communication unit 54 for business use communication (see communication path a in FIG. 1). . On the other hand, the mobile communication terminal 31 directly communicates with the Web server 12 connected to the Internet 9 via the carrier network 5 using the WAN communication unit 53 for communication for private use (communication path b in FIG. 1). reference).

  When the LAN communication unit 54 is connected to the access network 7 in the mobile communication terminal 33 but is not connected to the intranet 3 by the wireless LAN 4, the mobile communication terminal 33 uses the LAN communication unit 54 for business use communication. Is used to perform VPN communication with the Web server 12 (see communication path e in FIG. 1). In VPN (virtual private line) communication, the LAN communication unit 54 establishes a VPN (Virtual Private Network) tunnel 44 in the access network 7 and connects to the intranet 3. Further, the LAN communication unit 54 of the mobile communication terminal 33 communicates with the Web server 12 via the proxy server 15 after connecting to the intranet 3 via the VPN tunnel 44.

  On the other hand, the portable communication terminal 33 communicates directly with the Web server 12 using the LAN communication unit 54 for private use communication (see communication path f in FIG. 1). When the LAN communication unit 54 cannot be used at the same time for business use and private use, the communication control unit 51 of the mobile communication terminal 33 uses the WAN communication unit 53 for the private use communication and uses the carrier. You may communicate with the Web server 12 after connecting to the network 5. The communication control unit 51 of the mobile communication terminal 31 performs VPN communication with the intranet 3 using the WAN communication unit 53 for communication for business use, and Web using the LAN communication unit 54 for communication for private use. You may communicate directly with the server 12. Further, the communication control unit 51 of the mobile communication terminal 32 may use either the LAN communication unit 53 or the WAN communication unit 54 for communication in a time division manner.

  When the LAN communication unit 54 is not connected to the wireless LAN 4 in the mobile communication terminal 32, the mobile communication terminal 32 uses the WAN communication unit 53 to perform VPN communication with the Web server 12 for business use communication ( (See communication path c in FIG. 1). In VPN communication, the LAN communication unit 54 establishes a VPN tunnel 41 in the carrier network 5 and connects to the intranet 3. Further, the WAN communication unit 53 of the mobile communication terminal 32 communicates with the Web server 12 via the proxy server 15 after connecting to the intranet 3 via the VPN tunnel 41.

  On the other hand, the portable communication terminal 32 communicates directly with the Web server 12 using the WAN communication unit 53 for private use communication (see communication path d in FIG. 1). When the WAN communication unit 53 cannot be used simultaneously for business use and private use, the communication control unit 51 of the mobile communication terminal 32 may control the WAN communication unit 53 in time division.

  An operation of the mobile communication terminal 31 having the above-described configuration will be described.

  FIG. 4 is a flowchart showing a communication control procedure of the mobile communication terminal 31. The communication control program is stored in a ROM (Read Only Memory) in the communication control unit 51, and is executed when the start of communication is instructed by a CPU (Central Processing Unit) in the communication control unit 51.

  First, the communication control unit 51 as a usage type determination unit determines whether the communication is for business use or private use based on a user input operation (step S1). Here, the communication control unit 51 determines whether the communication corresponding to the user's input operation is for business use or private use, for example, an IP address, a MAC address, a URL, an email as an address of the destination (transmission destination) Judgment is made using an address.

  Further, when the user uses different addresses for business use and private use, it can be determined by the address of the transmission source, for example, an IP address, a MAC address, a URL, a mail address, or the like. Further, when the OS (operating system) is properly used for business use and private use, the determination can be made based on the type of OS. Further, when an application is used separately for business use and private use, determination can be made based on an application identification number (ID or the like). Also, it may be specified in advance whether the user is for business use or private use.

  When the communication is for business use (step S1, business use), the communication control unit 51 determines whether or not the LAN communication unit 54 is connected to the wireless LAN (step S2). When the LAN communication unit 54 is connected to the wireless LAN (step S2, YES), the communication control unit 51 determines whether or not the connection destination of the LAN communication unit 54 is the intranet 3 (step S3).

  Here, whether or not the connection destination of the LAN communication unit 54 is the intranet 3 is determined based on whether each IP address and / or subnet address acquired by DHCP (Dynamic Host Configuration Protocol) is set in advance. Can be determined by whether or not they match.

  In the case of a wireless LAN, the determination can also be made based on whether or not the SSID of the connected access point matches the SSID of the intranet 3 set in advance. It can also be determined by designating whether the user is the intranet 3 or not.

  When the connection destination of the LAN communication unit 54 is the intranet 3 (step S3, YES), the communication control unit 51 communicates by directly connecting to the intranet 3 using the LAN communication unit 54 as the case 1 described above ( Step S4). Thereafter, the communication control unit 51 ends the operation shown in FIG.

  Further, when the connection destination of the LAN communication unit 54 is not the intranet 3 in step S3 (step S3, NO), the communication control unit 51 uses the LAN communication unit 54 and the access network 7 via the wireless LAN 8 as the case 3 described above. A VPN tunnel 44 is established between them. The communication control unit 51 communicates by connecting to the intranet 3 via the VPN tunnel 44 (step S5). Thereafter, the communication control unit 51 ends the operation shown in FIG.

  Further, when the LAN communication unit 54 is not connected to the wireless LAN in step S2 (step S2, NO), the communication control unit 51 uses the WAN communication unit 53 as the case 2 as a communication method such as 3G or LTE. Thus, a VPN tunnel 41 is constructed with the carrier network 5 and communicates by connecting to the intranet 3 via the VPN tunnel 41 (step S6). Thereafter, the communication control unit 51 ends the operation shown in FIG.

  On the other hand, when the communication is private use in step S1 (step S1, private use), the communication control unit 51 determines whether or not the LAN communication unit 54 is connected to the wireless LAN (step S7). When the LAN communication unit 54 is connected to the wireless LAN (step S7, YES), the communication control unit 51 determines whether or not the connection destination of the LAN communication unit 54 is the intranet 3 (step S8).

  When the connection destination of the LAN communication unit 54 is the intranet 3 (step S8, YES), the communication control unit 51 connects to the carrier network 5 using the WAN communication unit 53 and connects to the Internet 9 as the case 1 described above. It communicates directly with the Web server 12 that has been made (step S9). Thereafter, the communication control unit 51 ends the operation shown in FIG.

  If the connection destination of the LAN communication unit 54 is not the intranet 3 in step S8 (step S8, NO), the communication control unit 51 uses the LAN communication unit 54 to connect to the access network 7 as described above. It communicates directly with the Web server 12 connected to the Internet 9 (step S10). Thereafter, the communication control unit 51 ends the operation shown in FIG.

  When the LAN communication unit 54 is not connected to the wireless LAN in step S7 (step S7, NO), the communication control unit 51 connects to the carrier network 5 using the WAN communication unit 53 as the case 2 described above. Communicate directly with the Web server 12 connected to the Internet 9 (step S11). Thereafter, the communication control unit 51 ends the operation shown in FIG.

  As described above, the portable communication terminal according to the first embodiment can be connected to an appropriate communication path according to the communication connection environment when switching the communication path between private use and business use. Therefore, convenience for both the user and the company (organization) can be achieved.

  Further, when the mobile communication terminal 31 is connected to the intranet 3, in the private use communication, the WAN communication unit 53 is selected and the communication is performed via the carrier network 5. Therefore, the private use communication is performed via the intranet. Can be done without.

  Further, when the LAN communication unit 54 is connected to the access network 7, a VPN tunnel 44 can be constructed in the access network 7 and connected to the intranet 3 for business use, and a communication path that ensures security can be connected.

  Even when the LAN communication unit 54 is not connected, for business use, the VPN tunnel 41 can be constructed in the carrier network 5 and connected to the intranet 3, and a communication path with security can be connected.
