In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a configuration of a communication system 1 according to the present embodiment. The communication system 1 is a system that causes the mobile communication terminal 10 to perform communication. The mobile communication terminal 10 is a device that is used by a user to connect to the mobile communication network N1 and perform mobile communication. Specifically, the mobile communication terminal 10 corresponds to a mobile phone or the like. The mobile communication terminal 10 can perform mobile communication when a user of the mobile communication terminal 10 makes a contract with a communication carrier of the mobile communication network N1. The mobile communication network N1 manages information related to the mobile communication terminal 10 based on the above contract, and can authenticate the mobile communication terminal 10 by using the information to communicate with the mobile communication terminal 10. Let Information relating to the mobile communication terminal 10 managed by the mobile communication network N1 includes information such as the telephone number, contract status, and usage status of the mobile communication terminal 10. The mobile communication terminal 10 may be the same as the conventional mobile communication terminal 10.

  The communication system 1 includes a connection system 2 and a communication control system 3 included in the mobile communication network N1. The connection system 2 is a system for connecting the mobile communication terminal 10 to the Internet N2, which is a network different from the mobile communication network N1 and the mobile communication network N1. That is, the connection system 2 mediates communication between the mobile communication terminal 10 and the mobile communication network N1 and the Internet N2. The connection system 2 is provided, for example, in the user's home, and is used to cause the mobile communication terminal 10 to perform wireless communication in the user's home and connect to the mobile communication network N1 or the like. Here, unlike the mobile communication network N1, the Internet N2 can perform communication as long as it can be connected (without requiring authentication or the like as performed in the mobile communication network N1).

  As shown in FIG. 1, the connection system 2 includes a femto base station 20, a home gateway 30, and a BB (broadband) router 40. The femto base station 20, the home gateway 30, and the BB router 40 are connected to each other by a cable or the like, and can transmit and receive information.

  The femto base station 20 is a device that performs wireless communication with the mobile communication terminal 10. The femto base station 20 transmits information input from the home gateway 30 or the BB router 40 to the mobile communication terminal 10 by a radio signal. Moreover, the femto base station 20 inputs the information transmitted / received between the mobile communication terminals 10 to the home gateway 30 or the BB router 40 according to the information. Note that the femto base station 20 is provided in the user's home by the user as described above, and is distinguished from the base station (ordinary base station) provided by the operator of the mobile communication network N1 (note that Functionally similar ones may be used).

  The mobile communication terminal 10 can be connected not only to the femto base station 20 but also to the mobile communication network N1 through a normal base station. In the mobile communication network N1, information indicating whether the location registration area is configured by the femto base station 20 or the normal base station (for example, corresponds to the location registration area ID). (In this case, the femto base station 20 and the normal base station are not mixed in the same location registration area). Also, in the mobile communication network N1, information on whether the base station is a normal base station or a femto base station 20 is stored (for example, in association with the base station ID) for each base station. Good. Therefore, in the mobile communication network N1, when the location of the mobile communication terminal 10 is registered, the mobile communication terminal 10 is located under a normal base station or is located under a femto base station 20. Is ascertained based on the above information.

  The home gateway 30 is a gateway for interconnecting an external network such as the mobile communication network N1 and the Internet N2 with a private network (not shown) in the home. It also has a function for connecting from the femto base station 20 to the Internet N2. The BB router 40 is a router for connecting the femto base station 20 and the home gateway 30 to an external network such as the mobile communication network N1 and the Internet N2. The BB router 40 is connected to the mobile communication network N1 and the Internet N2 through a broadband line (not shown) such as an optical line.

  Next, the configuration included in the mobile communication network N1 will be described. As shown in FIG. 1, the mobile communication network N1 includes a radio network controller (RNC) 50, a packet switching device SGSN (Serving GPRS Support Node) 60, and a GGSN (Gateway GPRS Support Node). 70 and WAP-GW (Wireless Application Protocol-Gateway) 80 are included. In the present embodiment, the communication control system 3 includes an SGSN 60 and a WAP-GW 80.

  As shown in FIG. 1, between the RNC 50 and the SGSN 60, between the SGSN 60 and the GGSN 70, and between the GGSN 70 and the WAP-GW 80 are connected by a cable or the like, and information can be transmitted and received.

  The RNC 50 is connected to a base station including the femto base station 20, and is a device that performs setting of a radio channel with the mobile communication terminal 10, handover control of the base station, and the like for each base station. The RNC 50 is normally connected to the femto base station 20 via a line termination device (femto gateway) (not shown) included in the mobile communication network N1. The line termination apparatus is an apparatus that connects the mobile communication network N1 and the femto base station 20 via the BB router 40 by converting signals on different lines.

  The SGSN 60 is a device that performs location registration, access management, and the like of the mobile communication terminal 10 located in the mobile communication network N1, for example, MSISDN (Mobile Station ISDN number definition) that is information for specifying the mobile communication terminal 10. Holding. The GGSN 70 is a device that controls packet communication in the mobile communication network N1. Specifically, the GGSN 70 has a function of transmitting an information transmission request of the mobile communication terminal 10 transmitted from the SGSN 60 to a device serving as a transfer destination.

  The WAP-GW 80 is a device that connects the mobile communication network N1 and other networks. When the mobile communication terminal 10 is connected to the mobile communication network N1 to communicate with a device (for example, the server device 90) included in another network, the server device is connected via the mobile communication network N1. 90 is a device designated as a transfer destination when connecting to 90.

  Subsequently, the server device 90 will be described. The server device 90 is a communication device that is a communication partner of the mobile communication terminal 10. The server device 90 is connected to the mobile communication network N1 or the Internet N2, and can be connected via any one of the networks N1 and N2. For example, the server device 90 is a device that provides the mobile communication terminal 10 with a function of accessing various servers for the mobile communication terminal 10 on the Internet N2 (specifically, the business of the mobile communication network N1). ISP (Internet Service Provider). The communication system 1 according to the present embodiment may include a server device 90. Further, the server device 90 may be a device managed by an operator of the mobile communication network N1.

  The communication system 1 according to the present embodiment is a system that communicates with the server device 90 via the Internet N2 when the mobile communication terminal 10 is located in the femto base station 20. Here, a basic process (and functions of each device necessary for it) performed when the mobile communication terminal 10 communicates with the server device 90 will be described. Note that communication via the Internet N2 (without going through the mobile communication network N1) reduces the communication charge generated by the user of the mobile communication terminal 10 through the mobile communication network N1. There is an advantage of reducing the load on the mobile communication network N1 for the operator of the mobile communication network N1. In the present embodiment, communication in which routing is performed via the Internet N2 is referred to as offload communication.

  When the mobile communication terminal 10 communicates with the server device 90, first, the mobile communication terminal 10 sends a connection request (PDP context activation request) to the mobile communication network N1 through the femto base station 20 and the BB router 40. Send. The connection request includes an APN (Access Point Name) that is information for designating a communication partner. Here, the APN specifies the server device 90. The APN is input in advance by a user or the like and stored in the mobile communication terminal 10. In the mobile communication network N1, connection processing is performed with the server device 90 based on the connection request, and the result is notified to the mobile communication terminal 10. As a result, the mobile communication terminal 10 becomes communicable with the server device 90.

  When the mobile communication terminal 10 transmits data to a device (server device 90) that is not included in the mobile communication network N1, data transmitted from the mobile communication terminal 10 is normally transmitted to the mobile communication network N1 and other networks. Need to be transmitted to the transmission destination via a device (WAP-GW 80 in this embodiment). When data is transmitted from the mobile communication terminal 10 based on the above connection, a device that connects the mobile communication network N1 and another network to the data needs to be designated as a transfer destination. There is. This transfer destination information is included in the notification of the connection process from the mobile communication network N1 to the mobile communication terminal 10.

  When data (U-Plane data) is transmitted from the mobile communication terminal 10 to the server device 90, a transmission request for data in which a transmission destination (Request-URI) and a transmission destination (Destination address) are specified is a mobile communication. It is transmitted from the terminal 10. Normally, this data transmission request is transmitted to the transmission destination via the mobile communication network N1. However, in this embodiment, as will be described later, the data transmission request is transmitted via the Internet N2 by the connection system 2 including the femto base station 20 and the home gateway 30.

  Even when data is transmitted and received between the mobile communication terminal 10 and the server device 90 without going through the mobile communication network N1 as described above, the mobile communication terminal 10 requests connection to the mobile communication network N1. Need to send. This is because the mobile communication terminal 10 normally cannot perform mobile communication unless it is controlled by the mobile communication network N1 that holds the contract information and the like of the mobile communication terminal 10. Note that once the connection (PDP context) between the mobile communication terminal 10 and the server device 90 is released, the above processing based on the connection request needs to be performed again.

  Subsequently, functions according to the present invention of each device included in the communication system 1 will be described. The femto base station 20 includes a connection request relay unit 21 and a data output unit 22.

  The connection request relay unit 21 is a connection request relay unit that receives a connection request (PDP context activation request) to the server device 90 from the mobile communication terminal 10 and transmits it to the mobile communication network N1. Specifically, the connection request relay unit 21 receives the connection request from the mobile communication terminal 10 by wireless communication. The connection request includes information for identifying the server device 90 that is the connection destination as an APN. The connection request relay unit 21 transmits the received connection request to the mobile communication network N1 via the BB router 40.

  Further, the connection request relay unit 21 receives from the mobile communication network N1 a radio link setting request that is a response to the transmission of the connection request to the mobile communication network N1. When the connection request relay unit 21 receives the wireless link setting request, the connection request relay unit 21 requests the home gateway 30 to perform setting so that data from the mobile communication terminal 10 can be transmitted via the Internet N2 (offload setting). Request). The connection request relay unit 21 includes information (described in detail later) included in the radio link setting request in the offload setting request.

  The data output unit 22 is a function of a data receiving unit that receives a transmission request for data (U-Plane data) from the mobile communication terminal 10 through the connection (PDP context) established by the connection request. The data output unit 22 determines whether or not the received information is the above data, and outputs the data to the home gateway 30 if it is determined as the above data.

  In addition, the data output unit 22 performs processing of conversion of the Destination address included in the transmission request and conversion of the Source address indicating the transmission source via the Internet N2. In communication with the server device 90 via the mobile communication network N1, the WAP-GW 80 of the mobile communication network N1 is designated as the Destination address. However, the data output unit 22 stores the address of the home gateway 30 in advance, and converts the destination address from the address of the WAP-GW 80 to the address of the home gateway 30 in communication via the Internet N2. In communication with the server device 90 via the mobile communication network N1, the source address is information for specifying the mobile communication terminal 10 only by the mobile communication network N1, and the mobile communication terminal 10 is specified by the Internet N2 or the like. I can't. Therefore, the data output unit 22 stores or acquires in advance information that can identify the mobile communication terminal 10 on the Internet N2 that is the destination network (for example, information given using DHCP (Dynamic Host Configuration Protocol)). The source address related to the transmitted data is converted into information that can identify the mobile communication terminal 10 on the Internet N2.

  Note that the above conversion or the like is not necessarily performed in an environment where no problem occurs even if conversion is not performed. The above conversion processing is also described in the specification of Japanese Patent Application No. 2008-208131, which is an application invented by the present inventor.

  The home gateway 30 includes an additional information receiving unit 31, a communication path establishing unit 32, a data receiving unit 33, and a data transmitting unit 34. The additional information receiving unit 31 is an additional information receiving unit that acquires header information transmitted from the communication control system 3 of the mobile communication network N1 in response to transmission of a connection request to the server device 90 by the connection request relay unit 21. One function. The header information is used when the mobile communication terminal 10 is located in a base station included in the mobile communication network N1 (not via the Internet N2) and transmits data to the server device 90 via the mobile communication network N1. , Additional information added to the header of the data. The header information is based on information related to the mobile communication terminal 10 managed by the mobile communication network N1, and is specifically information such as a telephone number, a contract status, and a usage status. The header information is used in the server device 90 to identify the mobile communication terminal 10 (the user) and the call (connection), and the service is provided after the identification.

  As will be described later, the header information is transmitted from the mobile communication network N1 to the femto base station 20 and is included in the radio link setting request received by the connection request relay unit 21. That is, the connection request relay unit 21 is a function of additional information receiving means for receiving header information. The connection request relay unit 21 includes the header information in the offload setting request and transmits it to the home gateway 30. The additional information receiving unit 31 acquires header information from the offload setting request received by the home gateway 30. The additional information receiving unit 31 outputs the acquired header information to the data transmitting unit 34.

  The communication path establishment unit 32 acquires information for communication path used for establishing a predetermined communication path between the connection system 2 and the server apparatus 90 from the server device 90 via the Internet N2, and It is communication path establishment means for establishing a predetermined communication path with the server device 90 using information. This communication path is intended to achieve high security even when data is transmitted / received via the Internet N2 rather than via the mobile communication network N1 that normally achieves high security. is there. For example, the communication path established with the server device 90 is a VPN (Virtual Private Network), and the communication path information is a one-time password used for VPN establishment processing.

  As will be described later, the communication path information is included in the wireless link setting request transmitted from the mobile communication network N1 to the femto base station 20 and received by the connection request relay unit 21. That is, the connection request relay unit 21 is a function of a communication path establishment unit that receives communication path information. The connection request relay unit 21 includes the communication path information in the offload setting request and transmits it to the home gateway 30. The communication path establishment unit 32 acquires communication path information from the offload setting request received by the home gateway 30. The communication path establishment unit 32 performs VPN establishment processing with the server device 90 using the acquired communication path information. When the VPN is established, the communication path establishment unit 32 notifies the data transmission unit 34 to that effect. Note that the VPN establishment process with the server device 90 is performed via the BB router 40 (the process by the home gateway 30 is the same thereafter).

  The data receiving unit 33 is a function of a data receiving unit that receives a data transmission request from the mobile communication terminal 10 from the femto base station 20. The data reception unit 33 outputs the input data transmission request to the data transmission unit 34.

  In addition, the data receiving unit 33 may determine a communication device as a transmission destination from the Request-URI included in the data transmission request. For example, the above determination is performed when the home gateway 30 is connected not only to the Internet N2 but also to a home network or the like that is configured in the user's home and has a communication function. Specifically, the data receiving unit 33 stores the address (URI) of the communication device connected to the home network in advance, and if the Request-URI does not match the stored address, the data receiving unit 33 transmits to the Internet N2. Judged as data. In this case, when the data receiving unit 33 determines to transmit data to the Internet N2, the data receiving unit 33 outputs a data transmission request to the data transmitting unit 34. If it is determined that the data is for the home network, the data receiving unit 33 controls the data to be transmitted to the communication device of the home network.

  The data transmission unit 34 adds the header information acquired by the additional information reception unit 31 to the data related to the transmission request input from the data reception unit 33, and transmits the data to the server device 90 via the Internet N2. Means. The data transmission unit 34 transmits data to which the header information is added to the server device 90 using the VPN established by the communication path establishment unit 32.

  The home gateway 30 may also receive data transmitted from the server device 90 to the mobile communication terminal 10 using the VPN via the Internet N2, and output the data to the mobile communication terminal 10 via the femto base station 20. .

  The SGSN 60 includes a connection request reception unit 61 and a transmission source determination unit 62. The connection request receiving unit 61 is a connection request receiving unit that receives a connection request from the mobile communication terminal 10 to the server device 90 from the connection system 2. The connection request is received via the RNC 50 or the like. The SGSN 60 outputs the received connection request to the transmission source determination unit 62.

  The transmission source determination unit 62 is a transmission source determination unit that determines whether or not the connection request input from the connection request reception unit 61 is from a specific connection system 2. Specifically, the transmission source determination unit 62 determines whether or not the connection request is received via the femto base station 20 instead of the normal base station included in the mobile communication network N1. The above determination is a determination as to whether or not communication between the mobile communication terminal 10 and the server device 90 should be performed via the Internet N2 (offload communication) based on the PDP context activation request. The transmission source determination unit 62 stores information for specifying the femto base station 20 in advance. In addition, the transmission source determination unit 62 makes the above determination with reference to the location registration information of the mobile communication terminal 10 managed by the mobile communication network N1. The transmission source judgment unit 62 identifies the mobile communication terminal 10 that has transmitted the connection request from the connection request, and the mobile communication terminal 10 passes the femto base station 20 from the location registration information based on the stored information. It is determined whether or not location registration has been performed. When determining that the mobile communication terminal 10 has performed location registration via the femto base station 20, the transmission source determination unit 62 determines that a connection request has been received via the femto base station 20.

  When the transmission source determination unit 62 determines that the connection request is received via the femto base station 20, the transmission source determination unit 62 performs communication between the mobile communication terminal 10 and the server device 90 via the Internet N2. This is included in the connection request as an “offload flag”. The “offload flag” can be included in the connection request by including a value indicating the offload flag in a specific field of the connection request, for example. If the value indicating the offload flag is “1”, the offload flag is present, and if it is “0”, the offload flag is absent.

  If the transmission source determination unit 62 determines that the connection request is not received via the femto base station 20, no special processing is performed on the connection request. The transmission source determination unit 62 transmits the connection request (PDP context generation request) to the GGSN 70. In the SGSN 60, the connection request includes the MSISDN that identifies the mobile communication terminal 10. The GGSN 70 receives the connection request and transmits it to the WAP-GW 80 as a connection notification. The MSISDN is used for connection processing in the server device 90 or the like.

  The WAP-GW 80 includes a connection request processing unit 81. The connection request processing unit 81 receives the connection notification transmitted from the GGSN 70 and transmits it to the server device 90. Further, the connection request processing unit 81 transmits the header information added to the data transmitted from the mobile communication terminal 10 to the server device 90 to the connection system 2 in accordance with the determination by the transmission source determination unit 62 of the SGSN 60. It is a transmission means. The connection request processing unit 81 transmits the header information when the determination by the transmission source determination unit 62 is that the connection request is received via the femto base station 20.

  Specifically, the connection request processing unit 81 receives a connection notification response transmitted from the server device 90 in response to transmission of a connection request (connection notification) from the WAP-GW 80 to the server device 90, and receives the connection request. It is determined whether or not the notification response includes a one-time password used for VPN establishment processing. As will be described later, when the determination by the transmission source determination unit 62 is that the connection request is received via the femto base station 20 (in this case, as described above, the connection notification is offloaded. This is because the one-time password is included in the connection notification response.

  If the connection request processing unit 81 determines that the one-time password is included in the connection notification response, the connection request processing unit 81 generates header information corresponding to the mobile communication terminal 10 that transmitted the connection request. The header information is generated in the same manner as the conventional method (for example, the information included in the header information is acquired from the SGSN 60 and the GGSN 70 by the PDP context generation request and the connection notification). Then, the connection request processing unit 81 includes the generated header information in the received connection notification response. When the connection request processing unit 81 determines that the one-time password is not included in the connection notification response, the header information is not included in the connection notification response. The connection request processing unit 81 transmits a connection notification response to the GGSN 70.

  Note that the determination by the connection request processing unit 81 may not be as described above. For example, it may be determined whether or not an offload flag is included in the connection notification sent from the SGSN 70 to the WAP-GW 80. Specifically, the determination is made by referring to a field of the connection request in which a value indicating an offload flag is included.

  Further, as described above, when the offload flag is included in the connection notification, the connection notification response transmitted from the server device 90 includes the one-time password used for the VPN establishment process. That is, the connection request processing unit 81 is a communication path information relay unit that receives communication path information and transmits it to the connection system 2.

  The server device 90 includes a transmission source information reception unit 91 and a communication path information transmission unit 92. The transmission source information reception unit 91 is transmission source information reception means for receiving a notification of a determination result as to whether or not the connection request received by the communication control system 3 is via the femto base station 20. Specifically, the transmission source information receiving unit 91 receives a connection notification including the above determination result as an offload flag from the WAP-GW 80. The transmission source information reception unit 91 outputs the connection notification to the communication path information transmission unit 92.

  The communication path information transmission unit 92 communicates the communication path information, that is, the one-time password used for the VPN establishment process, according to the offload flag included in the connection notification input from the transmission source information reception unit 91. It is communication path information transmitting means for transmitting to the control system 3. The communication path information transmitting unit 92 determines whether or not an offload flag is included in the connection notification. If it is determined that the offload flag is included in the connection notification, the communication path information transmitting unit 92 issues (generates) a one-time password, and is transmitted to the WAP-GW 80. The connection notification response to the connection notification Include a one-time password. A conventional method can be used to pay out the one-time password. If it is determined that the offload flag included in the connection notification is not included, the communication path information transmitting unit 92 does not perform the process of including the one-time password in the connection notification response. Further, when the connection notification is received, the server device 90 performs processing similar to the conventional processing (connection notification response generation, etc.) related to the connection notification.

  The communication path information transmitting unit 92 transmits the connection notification response to the WAP-GW 80. The WAP-GW 80 receives the connection notification response and transmits it to the GGSN 70. The GGSN 70 receives the connection notification response and transmits it to the SGSN 60 as a PDP context generation response. The SGSN 60 receives the PDP context generation response and transmits it to the RNC 50 as a radio bearer setting request. The RNC 50 receives the radio bearer setup request and transmits it to the femto base station 20 as a radio link setup request. When the wireless link setting request includes an offload flag in the connection request, the header information and the one-time password are included as described above.

  In addition, the server device 90 performs VPN establishment processing with the home gateway 30 via the Internet N2 performed in response to transmission of the one-time password. The server device 90 transmits and receives data to and from the mobile communication terminal 10 using VPN. The above is the configuration of the communication system 1.

  FIG. 2 shows a hardware configuration of the devices 20, 30, 40, 50, 60, 70, 80, 90 included in the communication system 1. As shown in FIG. 2, each of the devices 20, 30, 40, 50, 60, 70, 80, 90 includes a CPU (Central Processing Unit) 101, a RAM (Random Access Memory) 102 as a main storage device, and a ROM (Read Only). Memory) 103, a communication module 104 for performing communication, and a computer including hardware such as an auxiliary storage device 105 such as a hard disk. The functions of the above-described devices 20, 30, 40, 50, 60, 70, 80, 90 are exhibited by the operation of these components by a program or the like. For example, among the above devices, the femto base station 20 is also provided with hardware such as an antenna for performing wireless communication with the mobile communication terminal 10. Any of the devices 20, 30, 40, 50, 60, 70, 80, 90 can be realized by a hardware configuration similar to that of a conventional device.

  Subsequently, processing (communication control method) executed by the communication system 1 according to the present embodiment will be described using the flowcharts of FIGS. 3 and 4. This processing is processing when the mobile communication terminal 10 communicates with the server device 90 via the femto base station 20 (for example, when the user is located at home). First, processing at the start of communication (connection establishment processing) will be described with reference to FIG. 3, and then data transmission / reception processing and processing at the end of communication will be described with reference to FIG. The process is triggered by the user performing an operation on the mobile communication terminal 10 or the like.

  First, a connection request (PDP context activation request) is transmitted from the mobile communication terminal 10 to the mobile communication network N1. The PDP context activation request includes an APN that designates the server device 90. The PDP context activation request is received by the connection request relay unit 21 of the femto base station 20 and transmitted to the mobile communication network N1 via the BB router 40. In the mobile communication network N1, the transmitted PDP context activation request is received by the connection request reception unit 61 of the SGSN 60 via the RNC 50 (S01, connection request relay step, connection request reception step). The PDP context activation request is input from the connection request reception unit 61 to the transmission source determination unit 62.

  Subsequently, the transmission source determination unit 62 determines whether or not communication between the mobile communication terminal 10 and the server device 90 based on the PDP context activation request is to be performed via the Internet N2 (offload communication). (S02, transmission source determination step). This determination is a determination as to whether or not the PDP context activation request is received via the femto base station 20. When it is determined that the PDP context activation request is received via the femto base station 20, it is assumed that offload communication is to be performed. When determined as such, the transmission source determination unit 62 includes an offload flag in the PDP context generation request based on the PDP context activation request. Further, the transmission source determination unit 62 includes MSISDN in the PDP context generation request. Subsequently, the transmission source determination unit 62 transmits a PDP context generation request including the offload flag to the GGSN 70 (S03, transmission source determination step).

  Subsequently, the PDP context generation request is received by the GGSN 70 and transmitted to the WAP-GW 80 as a connection notification (S04). In the WAP-GW 80, the connection request processing unit 81 receives a connection notification and transmits it to the server device 90 (S05, transmission source information reception step).

  In the server device 90, a connection notification is received by the transmission source information reception unit 91 (S05, transmission source information reception step). The connection notification is transmitted from the transmission source information receiving unit 91 to the communication path information transmitting unit 92. Subsequently, the communication path information transmitting unit 92 determines whether or not an offload flag is included in the connection notification (S06, communication path information transmitting step). When it is determined that the offload flag is included in the connection notification, the one-time password is issued by the communication path information transmitting unit 92 and included in the connection notification response to the connection notification (S07, transmission of communication path information). Step). Subsequently, a connection notification response is transmitted from the communication path information transmitting unit 92 to the WAP-GW 80 (S08, communication path information transmitting step).

  In the WAP-GW 80, a connection notification response is received by the connection request processing unit 81 (S08, communication path information relay step). Subsequently, the connection request processing unit 81 determines whether or not the received connection notification response includes a one-time password (S09, additional information transmission step). When it is determined that the one-time password is included in the connection notification response, the connection request processing unit 81 generates header information and includes it in the connection notification response (S10, additional information transmission step). Subsequently, a connection notification response is transmitted from the connection request processing unit 81 to the GGSN 70 (S11, additional information transmission step, communication path information relay step).

  Subsequently, the connection notification response is received by the GGSN 70 and transmitted to the SGSN 60 as a PDP context generation response (S12). The PDP context generation response is received by the SGSN 60 and transmitted to the RNC 50 as a radio bearer setting request (S13). Subsequently, the radio bearer setup request is received by the RNC 50 and transmitted to the femto base station 20 as a radio link setup request (S14). The femto base station 20 receives the radio link setting request. As shown in FIG. 3, the wireless link setting request includes the one-time password and header information included as described above by the connection request relay unit 21. The one-time password and header information need only be acquired by the femto base station 20 and need not be included in the radio link setting request, and are transmitted to the femto base station 20 as information different from the radio link setting request. Just do it.

  Subsequently, a setting process of a radio link and a radio bearer is performed between the mobile communication terminal 10, the femto base station 20, and the RNC 50 as in the conventional process (S15). Subsequently, an offload setting request is issued so that the connection request relay unit 21 of the femto base station 20 can perform setting so that data from the mobile communication terminal 10 can be transmitted to the home gateway 30 via the Internet N2. Performed (S16). The offload setting request includes the one-time password and header information included in the wireless link setting request. Further, in the offload setting request, information (for example, the source address after conversion (rewriting) in the femto base station 20 at the time of U-Plane communication) for the home gateway 30 to identify the mobile communication terminal 10 (user) in S34 described later. ) May be included. The home gateway 30 receives the offload setting request. Subsequently, in the home gateway 30, the additional information receiving unit 31 acquires header information from the offload setting request. The header information is output and stored from the additional information receiving unit 31 to the data transmitting unit 34 (S16, additional information receiving step).

  On the other hand, the communication path establishment unit 32 acquires a one-time password from the offload setting request and sets it as a password used to establish the VPN (S17, communication path establishment step). Subsequently, a VPN is established via the Internet N2 between the communication path establishment unit 32 and the server device 90 using the one-time password (S18, communication path establishment step). When the VPN is established, an offload setting response that is a response to the offload setting is performed from the home gateway 30 to the femto base station 20 (S19).

  Subsequently, a radio link setting response is sent from the femto base station 20 to the RNC 50 as in the conventional process (S20). Subsequently, a radio bearer setting response is sent from the RNC 50 to the SGSN 60 (S21). Subsequently, a PDP context activation response is sent from the SGSN 60 to the mobile communication terminal 10 (S22). The above is the process at the start of communication. With this process, the mobile communication terminal 10 is in a state where it can transmit and receive data to and from the server device 90 via the Internet N2.

  Next, data transmission / reception processing and communication end processing will be described with reference to FIG. First, data addressed to the server device 90 (U-Plane data) is transmitted from the mobile communication terminal 10 to the femto base station 20 as a data transmission request. In this data, the Destination address and Request-URI are designated as in the case where the conventional mobile communication terminal 10 transmits data via the mobile communication network N1. Here, the final data transmission destination indicated by the Request-URI is, for example, a communication device (for example, a Web server) connected via the function of the server device 90 instead of the server device 90, and the user Specified by. The Destination address is notified by the above PDP context activation response and is the address of the WAP-GW 80.

  In the femto base station 20, the transmission request is received by the data output unit 22 (S31, data reception step). Subsequently, the data output unit 22 rewrites the destination address related to the transmission request from the address of the WAP-GW 80 to the address of the home gateway 30 (S32). Further, the data output unit 22 rewrites the source address related to the transmission request to information that can identify the mobile communication terminal 10 on the Internet N2 (S33). Subsequently, a transmission request is output from the data output unit 22 to the home gateway 30 (S34).

  In the home gateway 30, the data reception unit 33 receives the transmission request (S34, data reception step). At this time, the data receiving unit 33 acquires in advance information for identifying the mobile communication terminal 10 (user) included in the offload setting request received in S16 by the additional information receiving unit 31, and the information and the server The mobile communication terminal 10 (user) may be determined by comparing a source address included in a transmission request for data addressed to the device 90 (U-Plane data). If the information matches, it is determined that the user is an appropriate user to be processed according to the present invention, and the subsequent processes (S35 to S35) are performed. On the other hand, if the information does not match, it is determined that the user is not an appropriate user to be processed according to the present invention, and the subsequent processing (S35-) according to the present invention is not performed (in this case, U− Data can be transmitted to the home network or the like according to the destination of the Plane data). Subsequently, the data receiving unit 33 determines the Request-URI related to the transmission request (S35). If it is determined by this determination that the transmitted data is data transmitted via the Internet N2 (data addressed to the server device 90), a data transmission request is sent from the data receiving unit 33 to the data transmitting unit 34. Is output.

  Subsequently, the data transmission unit 34 adds the header information acquired by the additional information reception unit 31 to the data related to the transmission request input from the data reception unit 33 (S36, data transmission step). Subsequently, the data transmission unit 34 transmits the data to which the header information is added to the server device 90 using the VPN established by the communication path establishment unit 32 (S37, data transmission step). At this time, the Destination address is rewritten to the address of the server device 90. Thereafter, data transmission / reception is performed between the mobile communication terminal 10 and the server device 90 in the same manner as described above (S38). The above is the data transmission / reception process.

  Next, processing at the end of communication will be described. First, the mobile communication terminal 10 transmits a PDP context release request that is a request for terminating communication. The femto base station 20 receives the PDP context release request. When the PDP context release request is received, the femto base station 20 determines that the PDP context release request is transmitted to the mobile communication network N1 instead of the Internet N2. Thereby, the PDP context release request is transmitted from the femto base station 20 to the mobile communication network N1, and is received by the SGSN 60 via the RNC 50 (S41).

  Subsequently, the PDP context release request is transmitted from the SGSN 60 to the GGSN 70 (S42). Subsequently, the PDP context release request is transmitted from the GGSN 70 to the WAP-GW 80 as a release request (S43). Subsequently, the release request is transmitted from the WAP-GW 80 to the server device 90 (S44). In the server device 90, when a release request is received, execution of processing for releasing the VPN is started (S45), and VPN release processing is performed with the home gateway 30 (S46). Thereafter, the release process is continued (S47), and the communication between the mobile communication terminal 10 and the server device 90 ends. The above is the processing at the end of communication.

  As described above, in the communication system 1 according to the present embodiment, when the mobile communication terminal 10 communicates with a communication device such as the server device 90 via the Internet N2, which is a network different from the mobile communication network N1, Header information is added when data is transmitted from the communication terminal 10 to the server device 90 via the Internet N2. Therefore, when the mobile communication terminal 10 communicates with the server device 90 via the Internet N2 different from the mobile communication network N1, the server device 90 identifies the mobile communication terminal 10 and the call connection based on the header information. Services are provided to the mobile communication terminal 10 above. That is, according to the communication system 1 according to the present embodiment, even when the mobile communication terminal 10 performs communication via a network other than the mobile communication network N1 such as the Internet N2, the mobile communication network N1. Communication can be performed in the same manner as in the case of via.

  Further, as described above, in the present embodiment, no special function is added to the mobile communication terminal 10 in realizing the present invention. Therefore, it is not necessary to add any function to the mobile communication terminal 10 possessed by the user, and the present invention can be implemented. Further, in realizing the present invention, the user does not need to perform a special operation on the mobile communication terminal 10. Therefore, even when communicating via the femto base station 20 and the Internet N2, it can be used in the same manner as when communicating via the base station of the mobile communication network N1.

  Furthermore, in the present embodiment, since the header information is added not by the mobile communication terminal 10 but by the communication system 1, the reliability is higher than when the header information is added by the mobile communication terminal 10. Is difficult to tamper with.

  Further, as in the present embodiment, in the communication control system 3, it is preferable to determine that the mobile communication terminal 10 is routed through the femto base station 20 based on the location registration information. According to this configuration, the communication control system 3 (WAP-GW 80) can reliably determine whether or not header information should be transmitted to the connection system 2, so that the present invention can be implemented reliably and appropriately. . However, it is only necessary to determine that the communication is via the femto base station 20, and the above method is not necessarily used.

  Further, as in the present embodiment, it is desirable to establish a VPN via the Internet N2 between the home gateway 30 and the server device 90 and perform data transmission / reception using the VPN. According to this configuration, data transmission / reception via the Internet N2 can be performed safely. In addition, since different information is used for each communication by the one-time password and the VPN is established, data transmission / reception can be performed more safely. Note that the VPN does not necessarily have to be established when communication is performed not through the Internet N2 but through a network that is relatively secure in security comparable to the mobile communication network N1. In addition, a highly secure communication path other than VPN may be used as the established communication path on the Internet N2. Further, when establishing a VPN between the home gateway 30 and the server device 90, a VPN communication path may be established between the femto base station 20 and the home gateway 30.

  In the present embodiment, the Internet N2 is used as a network different from the mobile communication network N1, but the Internet N2 is not necessarily required. In the present embodiment, the functions according to the present invention are included in the femto base station 20, the home gateway 30, the SGSN 60, and the WAP-GW 80. However, the function deployment is not necessarily limited to the above, Any arrangement that implements the function can be taken.
