name: PRA
full_form: Presence Reporting Area
context: P-GW to the OCS for online charging, and by the S-GW and P-GW for offline charging. When a PRA set i.e. PRA Identifier was subscribed to, the SGW/PGW additionally receives the PRA Identifier of the PRA set from the serving node, along with the individual PRA Identifier(s) belonging to the PRA set and indication(s) of whether the UE is inside or outside the individual Presence Reporting Area(s) , as described in TS 23.401[208]. Only the individual PRA Identifier(s) belonging to the PRA set and UE presence status(es) are reported to the OCS according to the corresponding subscription. For offline charging, the initial status of UE presence in the PRA(s) shall be captured in current counts and reported on first charging event. For online charging, this initial status shall be reported when received by the PCEF if quota have already been requested for the service usage, otherwise this initial status shall be reported on the first quota request. For PRA(s) subscribed-to by the OCS, the
description: The Presence Reporting Area (PRA) is a network function responsible for reporting the presence of User Equipment (UE) within specific geographic areas to the Online Charging System (OCS). It plays a crucial role in enabling location-based services and charging mechanisms.
explanation: Based on the context from 3GPP TS 32.251, section 5.1.4.2, PRA is classified as a Network Function due to its involvement in reporting UE presence within specific areas to the OCS for online and offline charging purposes.
