Revision Details

Release

First introduced.

Pre 21.24

Feature Description

The standardized QCI values—65, 66, 67, 69, and 70 support Mission Critical and Push-to-Talk (MC/PTT) applications. The standard QCIs are based on 3GPP TS 23.203 Release 12.

This feature supports the following functionality:

  • Creates, deletes, and updates default and dedicated bearers.

  • All applicable charging records include the standard QCI values.

  • All features related to QCIs work with the standard QCI values.

  • Creates, delets, and updates Dynamic rules from PCRF with QCI 67.

  • Creates and deletes Pre-defined rules with QCI 67

  • Allows WiFi HO for bearer with QCI 67

  • Supports S2B/S2A HO with MC QCIs

  • Allows LTE to Wi-Fi Handover for Bearer with QCI

  • Supprts Bulkstats for APN and SAEGW

  • MC-QCI values supports X-header insertion, DSCP marking, and EDR


Important

The standard QCIs supported and qualified in the CUPS architecture are 1-9, 65, 66, 67, 69, 70, 80, 82, 83.

Limitations

The following are the known limitations of this feature:

  • Does not support the overall eMPS functionality.

  • If require ecs credit-control session-mode per-subscriber is configured, then URR is treated for entire subscriber session including secondary bearers which can lead to a problem in some applications. In CUPS, use the credit-control-client override session-mode per-sub-session command at the APN level to override the session mode configuration.

Configure QCI

Use the qci-qos-mapping CLI command to configure the DSCP marking for QCI. 


config 
   qci-qos-mapping name  
      qcinum { gbr }  [ { downlink | uplink } [ user-datagram dscp-marking dscp-marking-value ][ encaps-header { copy-inner | copy-outer | dscp-marking dscp-marking-value ] ] 
    end

NOTES:

  • qcinum : Specify standard QoS Class Identifier between 1-9, 65,66,67,69,70,80,82,83 - integer 1..83.

  • gbr: Specifies that this QCI type is Guaranteed Bit Rate (GBR).

  • downlink: Configures parameters for downlink traffic.

  • uplink: Configures parameters for uplink traffic.

  • encaps-header { copy-inner | copy-outer | dscp-marking dscp-marking-value} : Specifies that the DSCP marking must be set on the encapsulation header for IP-in-IP, GRE, or GTP encapsulation.

    • copy-inner : Specifies that the DSCP marking is to be acquired from the UDP headers within the encapsulation.

    • copy-outer used to copy the DSCP value coming in the data packet from S1u interface to the data packet sent on the S5 interface and vice-versa.

    • dscp-marking dscp-marking-value : Specifies that the DSCP marking is to be defined by this keyword.

      dscp-marking-value is expressed as a hexadecimal number from 0x00 through 0x3F.

  • user-datagram dscp-marking dscp-marking-value : Specifies that the IP DSCP marking is to be defined by this keyword.

    dscp-marking-value is expressed as a hexadecimal number from 0x00 through 0x3F.
