Method for enabling network to fall back, terminal device, and access network device
Disclosed in the present application are a method for enabling a network to fall back, a terminal device and an access network device. The method comprises: a terminal device receives indication information sent by an access network, the indication information being used for indicating whether a first network supports a specific service to be executed by the terminal device; and if the indication information indicates that the first network does not support the specific service, the terminal device initiates the specific service in a second network. When the terminal device cannot initiate a specific service in a current network, the specific service can be initiated in another network based on an instruction of an access network, so that a complex signaling interaction between the terminal device and a core network is avoided, and a delay of a network fallback process is reduced.
