TS29.244-g30 5.4.15.3 PGW and SMF behaviour

5.4.15.3 PGW and SMF behaviour

A PGW, SMF or SMF/PGW shall apply APN rate control, Small Data Rate Control and Serving PLMN rate control by instructing the UP function to perform packet rate enforcement as described in clause 5.4.15.2 with the following additions:

5.4.15.3 PGWとSMFの動作 PGW、SMF、またはSMF / PGWは、APレート制御、スモールデータレート制御、およびサービングPLMNレート制御を、5.4.15.2で説明されているようにUP機能にパケットレート強制を実行するように指示することで適用します。

- Serving PLMN rate control:

- the Maximum Downlink Packet Rate shall be set to the DL rate permitted by the Serving PLMN rate control parameters;

- the CP function shall indicate to the UP function to not report the status of the packet rate usage.

NOTE: Serving PLMN rate control applies only to control plane PDU sessions and PDN connections. Uplink rate for Serving PLMN rate control is enforced by the MME or SMF, so it does not require support from the UP function.

- Small Data Rate Control:

- the CP function shall indicate to the UP function to report the status of the packet rate usage;

- the QER shall be associated to all the DL/UL PDRs of the PDU session;

- the CP function shall indicate "MO Exception Data" or non "MO Exception Data" to the UP function, if 'Additional Maximum Uplink/Downlink Packet Rates' is provided.

- APN rate control:

- the CP function shall indicate to the UP function to report the status of the packet rate usage;

- the QER shall be associated to all the PDRs of all PDN connections of the UE to the same APN, using the QER Correlation ID (see clause 5.2.1).

- the CP function shall indicate "MO Exception Data" or non "MO Exception Data" to the UP function, if 'Additional Maximum Uplink/Downlink Packet Rates' is provided.
