Abstract

A data communication method includes registering as a group and by a first data processing device of plural data processing devices, at least one second data processing device capable of communicating with the first data processing device; transmitting by the first data processing device and to the data processing devices, a first reception request for data; transmitting by the first data processing device and to the at least one second data processing device, a second reception request for the data when there is no response to the first reception request from the first data processing devices; and transmitting the data to the second data processing device, by the first data processing device and based on a response from the second data processing device.

Claims

1. A data communication method comprising:

registering as a group and by a first data processing device of a plurality of data processing devices, at least one second data processing device capable of communicating with the first data processing device;

transmitting by the first data processing device and to the data processing devices, a first reception request for data;

transmitting by the first data processing device and to the at least one second data processing device, a second reception request for the data when there is no response to the first reception request from the first data processing devices; and

transmitting the data to the second data processing device, by the first data processing device and based on a response from the second data processing device.

2. The data communication method according to claim 1, wherein

the transmitting of the first reception request for the data to the data processing devices includes transmitting the first reception request when broadcast communication is performed among the data processing devices.

3. The data communication method according to claim 1, further comprising

transmitting the data to the first data processing device, by the second data processing device and based on a transmission request that is for the data and from the first data processing device to the second data processing device.

4. The data communication method according to claim 1, further comprising

transmitting the data by a given second data processing device to which that the data has been transmitted, wherein the data is transmitted by the given second data processing device to a second data processing device excluding the given second processing device, when a plurality of second data processing devices are registered as the group.

5. The data communication method according to claim 1, further comprising

sharing terminal information that indicates each registered second data processing device, the terminal information being shared among the data processing devices by each of the data processing devices transmitting and receiving information indicating each second data processing device with which the data processing device can communicate, wherein

the transmitting of the second reception request includes transmitting the second reception request to the second data processing devices, based on the shared terminal information.

6. The data communication method according to claim 5, further comprising

transmitting the terminal information by the data processing devices and to the second data processing devices;

and

transmitting the data by a given second data processing device to which the data has been transmitted, wherein the data is transmitted by the given second data processing device to a second data processing device excluding the given second data processing device, when a plurality of second data processing devices are registered as the group.

7. A data communication system comprising:

a memory; and

a first data processing device configured to;

register as a group into the memory, at least one second data processing device capable of communicating with the first data processing device among a plurality of data processing devices,

receive a first reception request that is for data and to the data processing devices; and

transmit a task to the at least one second data processing device when the data is transmitted to the second data processing device.

8. The data communication system according to claim 7, wherein

the first data processing device is further configured to transmit the data to the second data processing device when there is no response to the first reception request from a first data processing device.

9. The data communication system according to claim 7, wherein

when there is a plurality of second data processing devices registered as the group, the task is an instruction to share the data among the second data processing devices.

10. The data communication system according to claim 7, wherein

the first data processing device is further configured to transmit the first reception request for the data to the data processing devices when broadcast communication is performed among the data processing devices.
