Feature Description
The Wireless Priority Services (WPS) feature provides finer control for priority handling over multiple interfaces. UPF supports WPS based on the message priority indicated by SMF.
The priority value set on SMF will be sent to UPF over N4 as part of the PFCP header. The message priority values from SMF/CUPS-CP are currently supported for Emergency, VoLTE, and non-VoLTE IMS sessions.
Note | WPS supports only N4 (SMF) and Sxa (cnSGW) terminations on UPF. WPS does not support Sxb (PGW-C) and Sxa (SGW-C) terminations in this release. |
