Abstract: A communication method is applied to a scenario in which a terminal moves from a first preset area of a first network to a second preset area of a second network. The method includes that a first core network device in the first network determines that Evolved Packet System (EPS) fallback of the terminal is triggered, and sends first information to a second core network device in the second network. The first information includes a first identifier or first indication information. The first identifier identifies a first dedicated bearer corresponding to the terminal. The first dedicated bearer includes a voice dedicated bearer or a video dedicated bearer. The first indication information indicates that the terminal falls back to the second network using an EPS fallback procedure.
