Abstract
A roadside communication device having a data relay function includes a receiving unit that receives mobile object data whose generator is a mobile object; a relay unit capable of relaying the mobile object data, the relaying involving a thinning process of an amount of data; and a transmitting unit that transmits thinning information about an execution status of the thinning process to an external device.
Claims14
A roadside communication device having a data relay function, the roadside communication device comprising:
- a receiving unit that receives mobile object data whose generator is a mobile object;
- a relay unit capable of relaying the mobile object data, the relaying involving a thinning process of an amount of data;
- and
- a transmitting unit that transmits thinning information about an execution status of the thinning process to an external device.
A data relay method for a roadside communication device having a data relay function, the data relay method comprising:
- a first step of receiving, by a receiving unit of the roadside communication device, mobile object data whose generator is a mobile object;
- a second step of relaying the mobile object data by a relay unit of the roadside communication device, the relaying involving a thinning process of an amount of data;
- and
- a third step of transmitting, by a transmitting unit of the roadside communication device, thinning information about an execution status of the thinning process to an external device.
A central apparatus capable of obtaining mobile object data whose generator is a mobile object, from a roadside communication device having a data relay function involving a thinning process of an amount of data, the central apparatus comprising:
- a communication unit that receives thinning information about an execution status of the thinning process from the roadside communication device;
- and
- a control unit that performs a predetermined process based on the thinning information received by the communication unit.
A computer program for causing a computer to perform a process to be performed by a central apparatus capable of obtaining mobile object data whose generator is a mobile object, from a roadside communication device having a data relay function involving a thinning process of an amount of data, the computer program causing the computer to function as:
- a communication unit that receives thinning information about an execution status of the thinning process from the roadside communication device;
- and
- a control unit that performs a predetermined process based on the thinning information received by the communication unit.
A data processing method for a central apparatus capable of obtaining mobile object data whose generator is a mobile object, from a roadside communication device having a data relay function involving a thinning process of an amount of data, the data processing method comprising:
- a first step of receiving, by a communication unit of the central apparatus, thinning information about an execution status of the thinning process from the roadside communication device;
- and
- a second step of performing, by a control unit of the central apparatus, a predetermined process based on the thinning information received by the communication unit.
