Embodiment approach
[0071] Such as figure 1 As shown, the communication control system 100 according to the embodiment of the present invention includes the communication control device 2 and two or more in-vehicle wireless devices 3 (3A to 3B). The communication control device 2 is connected to the vehicle-mounted wireless device 3 through a closed LTE network 4 , and an LTE server 1 is also connected to the LTE network 4 . Furthermore, the communication control device 2 and the in-vehicle wireless device 3 respectively constitute different LANs (Local Area Networks) 6 (6A-6C), and the communication terminals 5 (5A-5C) are connected to the respective LANs 6 (6A-6C).
[0072] The LTE side server 1 is a computer connected to the LTE network 4 . The LTE-side server 1 stores LTE identification numbers (ICCID: IC Card Identifier) of all in-vehicle wireless devices 3 managed by the user. In addition, the LTE side server 1 also stores the respective IP addresses of the communication control device ...

A communication control device (2) is provided with a correspondence table updating unit (12), and a corrected packet transmission unit (13). When a packet including the identification number of a first communication terminal connected to a first wireless machine is received from the first wireless machine, the correspondence table updating unit (12) updates a correspondence table in which the address of the wireless machine and the identification number of the communication terminal are associated and stored. When a packet received from a second wireless machine to which a second communication terminal is connected includes the address of the second wireless machine, the identification number of the second communication terminal and an identification number indicating the destination of the packet, and the identification number indicating the address is the identification number of the first communication terminal that is stored in the correspondence table, the corrected packet transmission unit (13) transmits the packet to the first wireless machine, and thereafter transmits a corrected packet including the address of the second wireless machine and the identification number of the second communication terminal to the first wireless machine.
Description
technical field [0001] The present invention relates to a communication control device, a wireless device, a communication control system, a communication control method, and a program. Background technique [0002] With the popularization of smartphones and tablet computers, mobile communication technologies such as LTE (Long Term Evolution, Long Term Evolution) and data communication technologies such as wireless LAN (Local Area Network, Local Area Network) are widely used. Each of these data communication technologies has its own advantages and disadvantages. For example, LTE has a wider coverage of radio waves than wireless LAN, but wireless LAN is cheaper for high-speed communication. [0003] For this reason, communication technologies combining various data communication technologies have also been developed in order to take advantage of their respective advantages. For example, patent document 1 discloses a technology that even if a communication terminal does not h...
