1. A method for detecting a terminal device in an idle state, wherein the method is applied to the terminal device, and the method comprises:
receiving a first system message, wherein the first system message comprises a first field, and the first field is used to indicate the terminal device in the idle state to periodically initiate random access; and
sending, by the terminal device in the idle state, a random access request to a network device based on the first field to enter a connected state, wherein the sending, by the terminal device in the idle state, a random access request to a network device based on the first field to enter a connected state comprises sending, by the terminal device in the idle state, the random access request to the network device periodically with a period of a first time period based on a first time period identifier, wherein the first field comprises the first time period identifier.
