COMMUNICATION CONTROLLER AND COMMUNICATION CONTROL METHOD

Abstract

A communication controller is a device which controls communication between an electronic device of a mobile object and an external device, and includes: a wireless communication device configured to communicate with the external device respectively via an external communication network; a reception unit configured to receive communication data including a transmission source local IP address from the electronic device; and a route control unit configured to input the received communication data to the wireless communication device based on the transmission source local IP address. The route control unit makes each address group including one or more transmission source local IP addresses correspond to one access point name and inputs the communication data to the wireless communication device.

Description

Claims

1. A communication controller which controls communication between a plurality of electronic devices present inside a mobile object and a plurality of external devices present outside the mobile object and is provided in the mobile object, the communication controller comprising: a wireless communication device configured to communicate with one or more external devices via an external communication network present outside the mobile object;a reception unit configured to receive communication data including a transmission source local IP address indicating a transmission source from the electronic devices; anda route control unit configured to input the received communication data to the wireless communication device based on the transmission source local IP address,wherein a plurality of access point names are allocated to the wireless communication device, andthe route control unit makes each address group including one or more transmission source local IP addresses correspond to one of the access point names and inputs the communication data to the wireless communication device.

2. The communication controller according to claim 1, wherein the plurality of access point names include an access point name used for user charged communication which is communication generating a charge to a user of the mobile object, and an access point name used for user free-of-charge communication which is communication not generating a charge to the user.

3. The communication controller according to claim 1, comprising a state acquisition unit configured to acquire communication state information about whether or not the communication between the electronic devices and the external device is being normally performed and transmit the acquired communication state information to the electronic devices.

4. The communication controller according to claim 3, wherein the communication state information includes information about whether or not each of the communication between the electronic devices and the route control unit, the communication between the route control unit and the wireless communication device for each access point name and the communication between the wireless communication device and the external device is normal.

5. The communication controller according to claim 1, wherein connection information indicating a correspondence relation between each address group and the access point name is stored, andthe route control unit inputs the communication data to the wireless communication device corresponding to the access point name which is made to correspond to the transmission source local IP address included in the communication data, based on the connection information.

6. The communication controller according to claim 5, wherein a plurality of pieces of the connection information for each country or region are stored, andthe route control unit uses the connection information corresponding to the country or the region where the mobile object is present to input the communication data to the wireless communication device corresponding to the access point name which is made to correspond to the transmission source IP address included in the communication data.

7. The communication controller according to claim 6, wherein the plurality of pieces of the connection information for each country or region include at least one transmission source local IP address which is made to correspond to the access point name used for the communication generating a charge to a user of the mobile object.

8. A communication control method performed by a computer of a communication controller which controls communication between a plurality of electronic devices present inside a mobile object and a plurality of external devices present outside the mobile object and is provided in the mobile object, the communication control method comprising: a step of receiving communication data including a transmission source local IP address indicating a transmission source from the electronic devices; anda step of inputting the received communication data to the wireless communication device based on the transmission source local IP address,wherein a plurality of access point names are allocated to the wireless communication device, andeach address group including one or more transmission source local IP addresses is made to correspond to one of the access point names and the communication data is inputted to the wireless communication device, in the step of inputting.
