A charging pile, including a central control module as well as a 5G communication module, a wireless local area network module and a memory which are connected to the central control module. The central control module receives, by the 5G communication module, a unicast request signal transmitted by a source base station; has a memory space reserved in the memory according to the unicast request signal, and transmits a ready-to-receive signal to the source base station by the 5G communication module; receives, by the 5G communication module, to-be-transmitted user information sent by the source base station, and stores it in the memory space in the memory; and forwards the to-be-transmitted user information to a user terminal or other charging piles by the 5G communication module, or forwards the to-be-transmitted user information to other charging piles by the wireless local area network module.
