Wireless communication service delivery using multiple data network names (DNNs)

A wireless communication network configured to serve a wireless User Equipment (UE) over multiple Data Network Names (DNNs), the wireless communication network comprising:

• UDM circuitry configured to detect a DNN reattach condition for one of the DNNs for the wireless UE and responsively transfer a DNN reattach message for the one DNN and the wireless UE to SMF circuitry;
• the SMF circuitry configured to receive the DNN reattach message for the one DNN and the wireless UE and responsively transfer the DNN reattach message for the one DNN and the wireless UE to AMF circuitry;
• the AMF circuitry configured to receive the DNN reattach message for the one DNN and the wireless UE and responsively transfer an N2 Packet Data Unit (PDU) session reattach message for the one DNN and the wireless UE to a Radio Access Network (RAN) that serves the wireless UE;
• and
• the AMF configure to receive an N2 PDU session request from the RAN for the one DNN and the wireless UE and responsively select a new SMF data for the PDU session and without SMF data modification for the other DNNs.
