Feature Description

The Wireless Priority Services (WPS) feature provides finer control for priority handling over multiple interfaces.

UPF supports WPS services based on the message priority indicated by SMF. The configured priority value set on SMF will be sent to UPF over N4 as part of the PFCP header.

For more information, refer to the WPS Prioritization chapter.

RCM supports WPS prioritization based on the priority determined between UPF and RCM. Earlier, RCM supported up to 4 queues with precedence values of 1, 2, 3, and 0 (no precedence) to create corresponding queues with the same session priority. Now, it is extended to 5 queues with precedence values of 1, 2, 3, 4, and 0 (no precedence). The session-priority-profile configuration (UPF) maps the received session priority (0–15) to precedence values 1-4.
