Abstract
A moving body communication system includes: a plurality of user apparatuses each used on a moving body; and a server that is configured to distribute, to at least one of the user apparatuses as a requester, commonly used data as data used commonly by the plurality of the user apparatuses, based on a request from the at least one of the user apparatuses. The user apparatus as the requester is configured to execute processing for acquisition of the commonly used data from an already-acquiring apparatus positioned around the requester via a narrow-area communication in response to that acquirability of the commonly used data via the narrow-area communication is notified as a response from the server to a distribution request.

A moving body communication system comprising:
- a plurality of user apparatuses each used on a moving body;
- and
- a server that is configured to distribute, to at least one of the user apparatuses as a requester, commonly used data as data used commonly by the plurality of the user apparatuses, based on a request from the at least one of the user apparatuses,
- wherein:
- the server and each of the plurality of user apparatuses are configured to be mutually communicable via a wide-area communication network;
- each of the plurality of the user apparatuses includes
- a reporting section that is configured to sequentially transmit, to the server, a position reporting packet as a communication packet indicating positional information on a current position, and
- a narrow-area communicator as a communication module configured to execute narrow-area communication as direct wireless communication not using the wide-area communication network with each different apparatus as a different one of the user apparatuses;
- the server includes
- a management database that is implemented by a predetermined rewritable storage medium, and is configured to store data indicating an acquisition status of the commonly used data and positional information on each of the user apparatuses,
- an apparatus information management section that is configured to update the positional information on each of the user apparatuses stored in the management database, based on the position reporting packet transmitted from each of the plurality of the user apparatuses,
- a peripheral apparatus search section that is configured to refer to the management database in response to receipt of a distribution request for the commonly used data from any one of the user apparatuses, and determine whether at least one already-acquiring apparatus as the user apparatus that has already acquired the commonly used data exists around the requester,
- a notification section that is configured to notify the requester of acquirability of the commonly used data via the narrow-area communication in response to a determination by the peripheral apparatus search section that the already-acquiring apparatus exists around the requester, and
- a distribution section that is configured to distribute the commonly used data in response to a determination by the peripheral apparatus search section that no already-acquiring apparatus exists around the requester;
- and
- the user apparatus as the requester includes
- a narrow-area line acquisition section that is configured to execute processing for acquisition of the commonly used data from the already-acquiring apparatus positioned around the requester via the narrow-area communication in response to that the acquirability of the commonly used data via the narrow-area communication is notified as a response from the server to the distribution request.

A communication system comprising:
- a plurality of user apparatuses each mounted on a moving body;
- and
- a server that is configured to distribute common data based on a request from the at least one of the user apparatuses as a requester, the common data being used commonly by the plurality of the user apparatuses,
- wherein:
- the server and each of the plurality of user apparatuses are configured to be mutually communicable via a communication network;
- each of the plurality of the user apparatuses transmit, to the server, a position reporting packet indicative of positional information on a current position of the corresponding user apparatus;
- each of the plurality of the user apparatuses includes a communication module that executes communication as direct wireless communication not using the communication network, with each different apparatus as a different one of the user apparatuses;
- the server includes a management database that stores data indicating an acquisition status of the common data and positional information on each of the user apparatuses;
- the server is configured to
- update the positional information on each of the user apparatuses stored in the management database, based on the position reporting packet transmitted,
- refer to the management database in response to receipt of a distribution request for the common data from the requester so as to determine whether at least one of the user apparatus that has already acquired the common data as an already-acquiring apparatus exists around the requester,
- notify the requester of acquirability of the common data via the communication in response to a determination that the already-acquiring apparatus exists around the requester, and
- distribute the common data in response to a determination that no already-acquiring apparatus exists around the requester;
- and
- the user apparatus as the requester is configured to execute processing for acquisition of the common data from the already-acquiring apparatus positioned around the requester via the communication, in response to that the server notifies the user apparatus as the requester that the common data is available to be acquired via the communication.
