| 摘要 |
<p>The present invention relates to a communication system and a communication method. Identifier information of each first communication terminal is preset and an index table of the identifier information of a first communication terminal and target information are set at a background server; a second communication terminal performs radio frequency interaction with the first communication terminal to trigger a target information acquisition process, and according to the identifier information of the triggered first communication terminal and the index table of the identifier information of a first communication terminal and target information stored at the background server, the target information corresponding to the triggered first communication terminal is acquired, the target information being location information of each first communication terminal; therefore, the present invention implements precise positioning in a small area by adopting a radio frequency technology.</p> |
