Syntax

Syntax Description

 apn-ambr max-ul mbr-up max-dl mbr-dwn { pgw-upgrade | prefer-as-cap } { local | minimum | rej-if-exceed }
remove apn-ambr

remove

Removes the APN-AMBR changes from the configuration for this APN profile.

max-ul mbr-up max-dl mbr-dwn

Defines the maximum bit rates for uplink (subscriber to network) and downlink (network to subscriber) traffic.

mbr-up is an integer from 0 through 1410065408.

mbr-dwn is an integer from 0 through 1410065408.

prefer-as-cap

This keyword configures the capping that is applied on the subscription value received from the HSS or the value received from the peer-node (MME/S4-SGSN) during inbound relocation. One of the following actions must be configured under prefer-as-cap -- Note that the resulting value is used for the QoS parameter and sent in the Create Session Request or the Modify Bearer Command (in case of HSS-initiated QoS/APN-AMBR modification) message:
  • local - The configured local value will be used.
  • minimum - The minimum (lowest) value of the configured local value or the HSS-provided value will be used.
  • reject-if-exceed - The request/procedure is rejected if the HSS-provided value exceeds the configured local value.

pgw-upgrade

MME only.

This keyword configures the QoS capping to be applied on the values received from the PGW during Attach / PDN-connectivity / Bearer-creation / Bearer-modification procedures. One of the following actions must be configured under pgw-upgrade -- Note that the resulting value is used for the QoS parameter and sent to the UE:
  • local - The configured local value will be used.
  • minimum - The minimum (lowest) value of the configured local value or the PGW-provided value will be used.
  • reject-if-exceed - The request/procedure is rejected if the PGW-provided value exceeds the configured local value.

Usage Guidelines

Use this command to define the MBR that will be enforced by the P-GW for both uplink and downlink traffic shaping.

For the MME, use the apn-ambr command to set local values QoS capping type to be applied for the APN-AMBR received from HSS/PGW/peer-node. One or both prefer-as-cap and/or pgw-upgrade must be configured to override the default behavior, which is to accept the received value from the HSS/peer-node/PGW.

Examples

A command similar to the following sets the APN-AMBR maximum uplink and maximum downlink bit rates for the QoS profile: 
qos apn-ambr max-ul 24234222 max-dl 23423423
A command similar to the following sets the prefer-as-cap minimumcapping action to be taken when the SGSN or MME receives outside of APN-AMBR maximum uplink and maximum downlink bit rates : 
qos apn-ambr max-ul 24234222 max-dl 23423423 prefer-as-cap minimum

This command associates a specific bearer control profile with this QoS profile.

Syntax

Syntax Description

associate bearer-control-profile bc_profile_name qci qci_value [ to  end_qci_value ]
remove associate bearer-control-profile bc_profile_name

remove

Add this command prefix to the command to delete the association between the QoS profile and the identified bearer-control-profile.

bc_profile_name

Identifies the name of the bearer control profile being associated with the QoS profile. Enter 1 to 64 alphanumeric characters.

qci qci_value [ to end_qci_value ]

qci - Identifies either a specific QoS class identifier (QCI) or a range of QCI:
  • qci_value - Enter an integer from 1 through 9 to identify a specific QCI.
  • to end_qci_value - Type "to" and then enter an integer from 2 through 9 that is greater than the QCI value entered for the beginning of the range.

Usage Guidelines

Use the associate command in Quality of Service Profile configuration mode to associate the bearer control profile with the QoS profile and map a specific QCI or a range of QCI to the bearer control profile being associated with the QoS profile.

A specific QCI cannot be associated to more than one bearer control profile. The QCI of the bearer is used to identify the applicable bearer control profile.
  • For dedicated bearers, the QCI of bearer is initially determined by the QCI value received from PGW during dedicated bearer activation or the value received from peer MME/S4-SGSN.
  • For default bearers, the QCI of bearer is initially determined by the subscription from HSS or the value received from peer MME/S4-SGSN during inbound relocation.

Examples

The following sample command associates the BCprof1 bearer control profile with the QoS profile and maps QCI 7 to this bearer control profile: 
associate bearer-control-profile BCprof1 qci 7

class

Configures local values for the traffic class (TC) parameters for the quality of service (QoS) configured for this QoS profile.

Important:

To enable any of the values/features configured with this command, the prefer-as-cap configuration (also in the QoS profile configuration mode) must be set to either local or both-hlr-and-local.

Usage Guidelines

This command defines the qualifying options (parameters) for each QoS traffic class defined for this QoS profile.

Repeat the command as often as needed with different options to define all required QoS criteria. For example, to configure the maximum bit rate (MBR) for the downlink and uplink directions for a traffic class, this command must be used twice, specifying mbr-down once and mbr-up once.

Advantage for local mapping of MBR: some HLRs cannot be configured with high MBR values. Using the mbr-map-up and the mbr-map-down parameters allows the SGSN to be configured to treat a specific HLR value as meaning the desired high MBR value. In a case where the HLR does not support HSPA+ bit rates, but the handsets and network do, this feature allows the operator to overcome limitations on the HLR and provide HSPA+ bit rates by overwriting the provisioned HLR-QoS MBR values with SGSN-configured values. When MBR mapping is configured, if QoS is preferred as the HLR value, then the subscription QoS MBR received from the HLR is compared with the "from" value in the table. If it matches, then it is converted to the value specified by the "to" value in the table. QoS negotiation happens based on the converted value.

Advantage for QoS capping with THP and ARP: Controlling THP and ARP via Operator Policy: This functionality can differentiate home vs. roaming subscribers, and prevent visiting subscribers from receiving a high-tiered service. For example, a service provider could offer service differentiation using Ultra/Super/Standard service levels based upon QoS; this could justify charging a corporate customer more to use the Internet APN than would be charged to a consumer. This could be accomplished by controlling the traffic handling priority (THP) over the air interface, i.e. THP 1 = Ultra, THP 2 = Super and THP 3 = Standard.

Examples

Use the following command to configure the entire conversational traffic class with predefined QoS options: 

 class conversational all-values

Now change the background class ARP from 3 to 2: 

 class background arp 2

Invalidate the THP parameter, by removing all value from the parameter, for the interactive class: 

remove class interactive thp
