Abstract: A network search method includes receiving, by a terminal device, a user operation, where the user operation requests communication with a network device by using a 5th Generation (5G) access technology; and when a cell with which the terminal device currently registers is a non-allowed area, searching for a second cell, where the second cell is an allowed area, so that the terminal device communicates with the network device in the second cell by using the 5G access technology. Therefore, when actively initiating a service, the terminal device in the non-allowed area may actively search for a cell that is an allowed area, to communicate with the network device by using the 5G access technology.
