Abstract: Provided are a method and device for sending identifier information or a call transfer request. The method for sending a call transfer request includes: determining that a call for which a UE initiates a transfer in a PS domain to a CS domain includes an emergency call; acquiring identifier information of an EATF to which the UE is anchored when initiating the emergency call; and initiating transfer of the emergency call of the UE in the CS domain according to the identifier information. By means of the technical solution, the problem that an emergency call cannot be transferred in a case of networking of multiple service domains is solved, and the effect of ensuring that transfer of the emergency call can be completed is further achieved.
