Abstract
A wireless communication system comprises Public Land Mobile Networks (PLMNs) that use Uniform Data Repositories (UDRs) to serve wireless User Equipment (UEs) over wireless network slices. A serving PLMN determines a UE Identifier (ID) for a wireless UE and a slice ID for a wireless network slice. The serving PLMN indicates the UE ID and the slice ID to a Service Communication Proxy (SCP) in the serving PLMN. The SCP selects a UDR in a different PLMN based on the UE ID and the slice ID. The SCP indicates the UE ID and the slice ID to the selected UDR in the different PLMN. The selected UDR in the different PLMN transfers UE information for the UE for delivery to the network element in the serving PLMN. The network element in the serving PLMN controls the wireless network slice for the wireless UE based on the UE information.
