Communication controller for electronic devices inside and outside a mobile object and associated communication control method

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 processor, a memory, and a wireless communication device which is a wireless transmitter and a wireless receiver, and which is configured to communicate with one or more external devices via an external communication network present outside the mobile object, wherein
• the processor:
• receives communication data including a transmission source local IP (Internet Protocol) address indicating a transmission source from the plurality of electronic devices;
• and
• inputs the received communication data to the wireless communication device based on the transmission source local IP address,
• wherein a plurality of access point names, each of which is transmitted to a corresponding communication carrier, are allocated to the wireless communication device,
• wherein a connection table is stored in the memory, the connection table includes connection information indicating a correspondence relation between each address group including one or more transmission source local IP addresses and the access point name made to correspond to the transmission source local IP addresses in each country or region, and
• wherein the processor specifies the country or the region where the mobile object is currently present based on position information obtained from an in-vehicle GPS (Global Positioning System) provided in the mobile object, reads the connection table from memory, makes each address group correspond to one of the access point names according to the connection information included in the connection table corresponding to the country or the region, and inputs the communication data to the wireless communication device.
