Abstract: A terminal upgrade method and a related device are provided. The method includes: encapsulating, by an element management system (EMS), an upgrade version file supported by a type of terminal as a multicast program and storing the multicast program in a multicast server, or sending an upgrade version file supported by a type of terminal to a multicast server; establishing, by the EMS, a version-address mapping relationship; delivering, by the EMS, the version-address mapping relationship to a terminal; and delivering an upgrade start instruction to the terminal, to trigger the terminal to send a multicast program on-demand request to the multicast server, so that the terminal receives the multicast program that is stored in the multicast program storage address of the terminal and sent by the multicast server, and the terminal performs a version upgrade operation according to the received multicast program.
