The embodiments of the present invention relate to the field of communications, and provided thereby are a report sending method, report receiving method, device and system, the method comprising: when radio link failure (RLF) occurs, a terminal generates an RLF report, the RLF report comprising relevant information about the wireless environment in which the terminal is located when the RLF occurs; the terminal receives a terminal information request sent by an access network device, the terminal information request being used for acquiring the RLF report generated by the terminal; and the terminal sends the RLF report to the access network device. According to the embodiments of the present invention, the access network device may identify the wireless environment where the terminal is located when RLF occurs according to an RLF report, so as to subsequently optimize and manage an accessed terminal on the basis of the wireless environment and to improve the access quality of the terminal.
