1. A method of operating a wireless communication system that comprises Public Land Mobile Networks (PLMNs) to use Uniform Data Repositories (UDRs) to serve wireless User Equipment (UEs) over wireless network slices, the method comprising:
a network element in a serving one of the PLMNs determining a UE Identifier (ID) for one of the wireless UEs and a slice ID for one of the wireless network slices and transferring a request that indicates the UE ID and the slice ID to a Service Communication Proxy (SCP) in the serving one of the PLMNs;
the SCP in the serving one of the PLMNs receiving the request from the network element, and in response, selecting one of the UDRs in a different one of the PLMNs based on the UE ID and the slice ID and transferring the request to the selected one of the UDRs in the different one of the PLMNs;
the selected one of the UDRs in the different one of the PLMNs receiving the request from the SCP and responsively transferring UE information for the one of the wireless UEs for delivery to the network element in the serving one of the PLMNs; and
the network element in the serving one of the PLMNs receiving the UE information transferred by the selected one of the UDRs and controlling the one of the wireless network slices for the one of the wireless UEs based on the UE information.
