JPL 5G User Plane Function (UPF) Partner Validated

Based on the control information from SMF, JPL’s UPF supports allocation of either one or both IPv4 and IPv6 addresses to UE. The UPF indicates support of the “UE IP Address/Prefix Allocation” feature in the PFCP Association Setup Request Message to SMF. The IP address assignment is done based on the data network name received from SMF during PFCP session establishment or modification request. Pools of IPv4 and IPv6 need to be configured for each data network. In case of IPv6 address allocation, /64 IPv6 prefix is allocated by the UPF. In case a PFCP session terminates, the UPF waits for a configurable duration before re-allocating that IP address to another UE.

 Inter-PLMN User Plane Security functionality at the border of the network protects networks from invalid inter-PLMN N9 traffic.

Tunnel IDs for receiving uplink traffic can be allocated by JPL’s UPF based on control information received from SMF. The UPF indicates to SMF the support of tunnel endpoint allocation by setting the “FTUP” feature flag in Association Setup Request. It can allocate a fresh tunnel or reuse one of the pre-created tunnels in that PFCP session based on the information received from SMF. In case a PFCP session terminates, UPF waits for a configurable duration before allocating that tunnel ID to another PFCP session.
