1. A roaming signaling message sending method, wherein the method comprising:
receiving, by a visited core network device, a roaming signaling message;
adding, by the visited core network device, an identifier of a home core network device and an identifier of a visited security edge protection proxy (SEPP) device into the roaming signaling message to generate a modified roaming signaling message; and
sending, by the visited core network device, the modified roaming signaling message to the visited SEPP device.
