Wireless communication network access using different functionality splits for different communication services

A wireless communication network to serve wireless User Equipment (UE) with different data communication services using different functionality splits, the wireless communication network comprising:

• Distributed Unit (DU) circuitry configured to wirelessly receive a service request for one of the data communication services from the UE and transfer the service request to Centralized Unit (CU) circuitry;
• the CU circuitry configured to receive the service request for the UE and transfer the service request for the UE to a wireless network controller;
• the wireless network controller configured to receive the service request for the UE, select one of the different functionality splits based on the service request, and transfer a service response for the UE indicating the selected one of the different functionality splits to the CU circuitry;
• the CU circuitry configured to receive the service response for the UE and transfer the service response for the UE to the DU circuitry;
• the DU circuitry configured to receive the service response for the UE, wirelessly exchange user communications with the UE, exchange the user communications with the CU circuitry, and when the selected one of the functionality splits for the UE uses the DU circuitry, the DU circuitry configured to process the user communications with at least some of a Physical Layer (PHY), Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), Radio Resource Control (RRC), and Service Data Adaptation Protocol (SDAP) based on the selected one of the different functionality splits;
• and
• the CU circuitry configured to exchange the user communications with the DU circuitry, exchange the user communications with a wireless network element, and when the selected one of the functionality splits for the UE uses the CU circuitry, the CU circuitry configured to process the user communications with at least some of the PHY, the MAC, the RLC, the PDCP, the RRC, and the SDAP based on the selected one of the different functionality splits.
