Limitations

The HR roaming support feature has the following limitations:

  • Router Advertisement (RA) or Router Solicitation (RS) packets are charged and counted in default QFI PDR on the vUPF.

  • No support for QER enforcement policing on the vUPF.

  • No support for LI on the vUPF.

  • UPF supports two GTPU endpoints at the ingress interface.

  • Secondary PDR Optimization support will not be enabled in-between, for an existing call.

  • After the upgrade, if the source interface type is not available in Create PDR.Then for existing calls, service selection will not happen based on interface type.

  • N9, S5U, and S8U interface types are supported only on the same public IP and not on different IPs.

  • Inter-PLMN handover works only with Secondary PDR optimization.

  • If any Access-side PDR handling fails, then UPF reports only the failed PDR ID and not both PDRs (primary and secondary).
