A processing device that is an edge computer connected to a base station communicatable with a vehicle in a service area includes: a request generation unit generating a first request including location information and a range from the location information specifying a region in which information sharing is requested, and an identifier from which a demander that requests the information sharing is identifiable; an accepted request holding unit holding a second request based on an information sharing demand from another processing device when shared information regarding the region is sendable in response to the second request; and a request location information inquiry unit generating the shared information including a cognitive event and the identifier held in the accepted request holding unit when location information indicating a cognitive event occurrence point acquired from the vehicle via the base station is included in a region specified by the second request information.

Processing device, communication device, communication system, control circuit, storage medium, and information sharing method

A communication device () receives internal electric waves () emitted toward inside a vehicle () by an internal communicator () mounted in the vehicle (), and receives external electric waves () emitted toward outside the vehicle () by an external communicator () mounted in the vehicle (). The communication device () determines whether the communication device () is inside the vehicle () or outside the vehicle (), from a reception intensity of the received internal electric waves () and from a reception intensity of the received external electric waves ().

Communication device, communication system, communication method, and computer readable medium

A reception unit receives from a wireless relay device, a handover response indicating possibility of degradation in communication quality during wireless communication with the wireless relay device. A search unit searches whether or not a wireless relay device to which handover can be performed is present other than the wireless relay device. When the wireless relay device to which handover can be performed other than the wireless relay device is present as a result of search by the search unit, a transmission unit transmits a handover request to the wireless relay device found by the search unit.
