Communication system, server apparatus, and communication method
Disclosed herein is a communication system including: a first apparatus and a second apparatus being communication terminals at least one of which resides on a mobile object; and a server apparatus. The server apparatus includes: a determination block configured to determine whether the first and the second apparatuses are in close proximity to each other based on position data of the first apparatus and on position data of the second apparatus; and a communication block configured such that if the determination block determines that the first and the second apparatuses are in close proximity to each other, the communication block transmits preinstalled content data to at least one of the first and the second apparatuses.
1. A communication system comprising:
a first communication terminal and a second communication terminal; and
a server apparatus,
wherein the server apparatus includes circuitry configured to
receive position data of the first communication terminal and position data of the second communication terminal,
determine at least one of a speed of movement and a direction of movement of at least one of the first communication terminal and the second communication terminal,
determine whether the first communication terminal and the second communication terminal are within a predetermined distance of each other and pass each other based on the position data of the first communication terminal, the position data of the second communication terminal, and said at least one of the speed of the movement and the direction of the movement, and
transmit, if it is determined that the first communication terminal and the second communication terminal are within the predetermined distance of each other and pass each other, content data including information concerning an area ahead of the direction of the movement to at least one of the first communication terminal and the second communication terminal.
2. The communication system according to claim 1 , wherein the circuitry of the server apparatus is configured to receive the position data transmitted from the first communication terminal as well as the position data transmitted from the second communication terminal.
3. The communication system according to claim 1 , further comprising a content providing apparatus including circuitry configured to provide the content data to the server apparatus.
4. The communication system according to claim 1 , wherein the content data is provided by at least one of the first communication terminal and the second communication terminal.
5. The communication system according to claim 1 , wherein the first communication terminal and the second communication terminal are mobile objects.
6. The communication system according to claim 5 , wherein, if it is determined that the first communication terminal and the second communication terminal pass each other at a predetermined timing, the circuitry of the server apparatus is configured to transmit the content data in a manner asynchronous with the predetermined timing.
7. The communication system according to claim 1 , wherein the content data is associated with data about the timing at which the content data is transmitted.
8. A server apparatus comprising:
circuitry configured to
receive position data of a first communication terminal and position data of a second communication terminal;
determine at least one of a speed of movement and a direction of movement of at least one of the first communication terminal and the second communication terminal,
determine whether the first communication terminal and the second communication terminal are within a predetermined distance of each other and pass each other based on the position data of the first communication terminal, the position data of the second communication terminal, and said at least one of the speed of the movement and the direction of the movement; and
transmit, if it is determined that the first communication terminal and the second communication terminal are within the predetermined distance of each other and pass each other, content data including information concerning an area ahead of the direction of movement to at least one of the first communication terminal and the second communication terminal.
9. A communication method, in a communication system, comprising:
receiving position data of a first communication terminal and position data of a second communication terminal;
determining at least one of a speed of movement and a direction of movement of at least one of the first communication terminal and the second communication terminal,
determining whether the first communication terminal and the second communication terminal are within a predetermined distance of each other and pass each other based on the position data of the first communication terminal, the position data of the second apparatus, and said at least one of the speed of the movement and the direction of the movement; and
if it is determined that the first and the second apparatuses are within the predetermined distance of each other and pass each other, then transmitting content data concerning an area ahead of the direction of movement to at least one of the first communication terminal and the second communication terminal.
