On-vehicle communication device and communication management method

1. A communication management method of managing a communication between an on-vehicle communication device and a communication carrier using the on-vehicle communication device and a management server, the on-vehicle communication device being mounted on a vehicle, the management server placed outside the vehicle and configured to manage the on-vehicle communication device, the communication management method comprising:

flag transmission of transmitting, to the on-vehicle communication device, identification flag information for identifying a function to be enabled among a plurality of functions of the vehicle, using the management server;

port assignment of assigning different dedicated source ports for respective functions to be enabled based on the identification flag information, using the on-vehicle communication device, upon receipt of the identification flag information; and

data communications for the respective functions assigned to the dedicated source ports in the port assignment via the dedicated source ports to allow a communication carrier to accumulate data traffic for the respective functions, using the on-vehicle communication device,

wherein

the identification flag information includes port designation information designating a transmission source port for an assignment destination so that the different dedicated source ports are assigned for the respective functions, and

the communication management method further comprising: information provision of providing the communication carrier with information on the transmission source ports assigned for the respective functions, using the management server.

2. The communication management method of claim 1 , further comprising:

registration of registering, in a management table, identification flag information for identifying a function to be enabled, upon receipt of contract information on a contract for the function between the vehicle and a service provider that provides a service to the vehicle, using the management server, wherein

the flag transmission includes transmitting, as the identification flag information for identifying the function to be enabled, the identification flag information registered in the registration, using the management server.

3. The communication management method of claim 2 , wherein

the management server includes a plurality of reverse proxy servers, and

the data communications of the on-vehicle communication device in the data communication are executed via the reverse proxy servers assigned based on the identification flag information.

4. A communication management method of managing a communication between an on-vehicle communication device and a communication carrier using the on-vehicle communication device and a management server, the on-vehicle communication device being mounted on a vehicle, the management server placed outside the vehicle and configured to manage the on-vehicle communication device, the communication management method comprising:

flag transmission of transmitting, to the on-vehicle communication device, identification flag information for identifying a function to be enabled among a plurality of functions of the vehicle, using the management server;

port assignment of assigning different dedicated source ports for respective functions to be enabled based on the identification flag information, using the on-vehicle communication device, upon receipt of the identification flag information;

data communications for the respective functions assigned to the dedicated source ports in the port assignment via the dedicated source ports to allow a communication carrier to accumulate data traffic for the respective functions, using the on-vehicle communication device; and

registration of registering, in a management table, identification flag information for identifying a function to be enabled, upon receipt of contract information on a contract for the function between the vehicle and a service provider that provides a service to the vehicle, using the management server, wherein

the flag transmission includes transmitting, as the identification flag information for identifying the function to be enabled, the identification flag information registered in the registration, using the management server.

5. The communication management method of claim 1 , wherein

the management server includes a plurality of reverse proxy servers, and

the data communications of the on-vehicle communication device in the data communication are executed via the reverse proxy servers assigned based on the identification flag information.

6. The communication management method of claim 1 , wherein

the management server includes a plurality of reverse proxy servers, and

the data communications of the on-vehicle communication device in the data communication are executed via the reverse proxy servers assigned based on the identification flag information.

7. The communication management method of claim 4 , wherein

the management server includes a plurality of reverse proxy servers, and

the data communications of the on-vehicle communication device in the data communication are executed via the reverse proxy servers assigned based on the identification flag information.

8. The communication management method of claim 1 , further comprising:

executing, by using the on-vehicle communication device, processing of enabling the function, upon receipt of the identification flag information, based on the identification flag information transmitted in the flag transmission, wherein

in the processing of enabling, upon receipt of information on a service provider of the function to be enabled as the identification flag information, an application of the service provided for a voice search service and/or for a streaming service is enabled.

9. The communication management method of claim 1 , further comprising:

executing, by using the on-vehicle communication device, processing of enabling the function, upon receipt of the identification flag information, based on the identification flag information transmitted in the flag transmission, wherein

in the processing of enabling, upon receipt of information on a service provider of the function to be enabled as the identification flag information, an application of the service provided for an Internet radio and/or for a surrounding information providing service is enabled.

10. The communication management method of claim 1 , wherein

in the port assignment, upon receipt of information on a service provider of the function to be enabled as the identification flag information, the transmission source port that is dedicated to the data communication regarding a payment application of the service provider.

11. An on-vehicle communication device for connecting an on-vehicle device mounted on a vehicle to an external network, the on-vehicle communication device comprising:

a storage unit configured to store a correspondence relationship between respective functions to be enabled out of a plurality of functions of the on-vehicle device and different transmission source ports assigned for the respective functions; and

a control unit configured to assign a transmission source port different from the transmission source ports for a new function to be enabled different from the respective functions stored in the storage unit, upon receipt of new identification flag information for identifying the new function from an outside of the vehicle, store information on the assignment, and perform control for information communications for the respective functions, that are enabled, via their respective transmission source ports, wherein

the control unit executes, upon receipt of, as the identification flag information, information on a service provider providing an application as the function to be enabled from outside of the vehicle, processing of enabling the application of the service provider.
