Quality of Service (QoS) Management for SGSN
▀ Quality of Service Management
▄ SGSN Administration Guide, StarOS Release 18
To specify the operational preferences of QoS Parameters (specifically the QoS bit rates), use the following procedure:
config
apn-profile <profile_name>
qos prefer-as-cap { both-hlr-and-local | both-hss-and-local { local-when-
subscription-not-available | minimum | subscription-exceed-reject } | hlr-subscription |
local }
subscription-not-available | minimum | subscription-exceed-reject } | hlr-subscription |
local }
exit
To remove all the previous configurations and reset the values to default, use the following procedure:
config
apn-profile <profile_name>
remove qos prefer-as-cap
exit
QoS Management When UE is Using S4-interface for PDP Contexts
The SGSN uses the S4 interface with EPC network elements S-GW or P-GW. The QoS parameters used in the EPC
network are different from the ones used in GPRS/UMTS network. For more information refer to the 3GPP TS 23.203
section 6.1.7.

EPC QoS Parameters
QoS Class Identifier (QCI): The QCI is scalar that is used as a reference to node specific parameters that
control packet forwarding treatment (for example, scheduling weights, admission thresholds, queue
management thresholds, link layer protocol configuration and so on.) and that have been pre-configured by the
operator owning the node (for example, eNodeB). The standardized characters associated with a standard QCI
are listed below:
