Abstract: A method to reduce signaling interaction in an access process of a terminal includes: receiving, by a convergent network device, an access request message from a first access device on a first network, where the access request message carries a first globally unique temporary identity (GUTI) of a terminal, which is an old GUTI on the first network or a GUTI on the first network and obtained by mapping a second GUTI on a second network; determining, by the convergent network device, a first target context of the terminal on the first network based on the first GUTI and a device identifier corresponding to the convergent network device when serving as a mobility management device; and sending, by the convergent network device, an access response message to the first access device to indicate that the terminal has successfully accessed the first network.
