摘要： To serve User Equipment (UEs) in a wireless communication network, a control-plane transfers a co-located User Plane Function (UPF) request for a wireless access point ID to a naming system. The naming system detects a co-location translation fault for the wireless access point ID and transfers the wireless access point ID to a controller. The controller determines co-located UPFs for the wireless access node. The controller transfers co-location translation information for the wireless access point ID and co-located UPF IDs to the naming system. The control-plane transfers another co-located UPF request for the wireless access point ID to the naming system. The naming system translates the wireless access point ID into the set of co-located UPF IDs. The naming system transfers the co-located UPF IDs to the control-plane. The control-plane signals the co-located UPFs to serve the UE over the wireless access point.

摘要： A Gateway Control Plane (GW-C) receives a session request for User Equipment (UE) from a serving Access Point (AP) and transfers an Access Gateway User Plane (AGW-U) request that has network data and the AP Identifier (ID). The GW-C receives an AGW-U response that indicates a translation fault for the AP ID. A translation controller transfers a translation request that has the Tracking Area Indicator (TAI) for the UE. A Domain Name System (DNS) translates the TAI into AGW-U IDs and External Gateway User Plane (EGW-U) IDs. The translation controller determines a co-located group of the AGW-Us and the EGW-Us and adds a location ID to the AGW-U IDs and the EGW-U IDs in the co-located group. The translation controller generates translations of the AP ID into the AGW-U IDs and of the AGW-U IDs into the EGW-U IDs. The translation controller transfers the translations to the DNS.

摘要： In a wireless communication network, a Gateway Control Plane (GW-C) receives a session request for a User Equipment (UE) from an Access Point (AP) that serves the UE. The GW-C transfers a DNS request having an AP ID and network data. A Domain Name System (DNS) translates the AP ID and the network data into an AGW-U ID and an EGW-U ID for co-located GW-Us. The GW-C receives a DNS response and transfers GW control signals using the AGW-U ID and the EGW-U ID. The co-located AGW-U and EGW-U serve the UE responsive to the control signals. In some examples, the selected AGW-U and EGW-U are co-located at the network edge near the AP.
