step S406: the signaling interworking gateway sends the processed subscription request message to a network element B;
step S408: when the subscribed time in the network element B occurs or the subscribed data is modified, the network element B sends a notification message to a signaling interworking gateway according to the URI in the received subscription request message;

step S504: the signaling interworking gateway replaces the IP address and the port of the private network AMF of the callback URI in the subscription request message with the IP address and the port of the private network AMF, encrypts the IP address and the port of the private network AMF through an encryption algorithm, and finally adds the encrypted content into the callback URI, wherein the modified callback URI format is as follows: port/called service/IMSI of user/IP of encrypted private network AMF;
step S506: the signaling interworking gateway sends the processed subscription request message to an operator network aggregation UDM (which is an example of the second network element);
step S508: when the user subscription data is sent and changed, the operator network intensive UDM sends a subscription notification message to a signaling interworking gateway according to a callback URI in a received subscription request message;
step S510: the signaling interworking gateway decrypts the encrypted content of the callback URI in the subscription notification message to obtain the IP address and the port of the private network AMF, and restores the callback URI, wherein the restored callback URI is consistent with the callback URI in the subscription request message sent by the private network AMF;
