Relay device and communication system

Japanese Patent JP6335079

B2

A relay device relays a signal between a first network and a second network. The relay device includes a first circuitry to wirelessly communicate with a wireless terminal over the first network and communicate with a first relay device over the second network. The relay device includes a second circuitry to detect a communication request transmitted by the wireless terminal. The relay device includes a third circuitry to decide whether relay of object information corresponding to the communication request is able to be completed with the wireless terminal while the wireless terminal stays within a wireless communication range of the relay device, and causes the first circuitry to transmit a request signal to request to relay a part or a whole of the object information to the first relay device instead of said relay device when a result of decision indicates that the relay is not able to be completed.
