Abstract
The present disclosure relates to example service processing methods and devices. In one example method, a request message for setting up a Voice over Long Term Evolution (VoLTE) service for a user equipment (UE) in a packet switched (PS) domain is received by an Internet Protocol multimedia subsystem (IMS) core network device. The IMS core network device triggers a circuit switched fallback (CSFB) service of the UE after determining that the VoLTE service cannot be set up in the PS domain.
