qos allow-upgrade
Configure this command to allow upgrade of QoS from GGSN. The “Upgrade QoS Supported” flag is now set in
“Create PDP Context” and “Update PDP Context” messages sent by SGSN. The SGSN signals the availability of this
functionality by use of the “Upgrade QoS Supported” bit within the Common Flags IE. The SGSN sets the “Upgrade
QoS Supported” bit within the Common Flags IE to “1” within the “Create PDP Context” and “Update PDP Context”
procedures.

network scenario.
prefer-as-cap-subscription
Enable this optional keyword to configure capping of QoS with Subscribed QoS (local/HLR). If this keyword
is enabled, SGSN accepts a higher QoS in the Create/Update PDP Context Response than sent in
Create/Update PDP Context Request, but negotiates and restricts the value within HLR/local subscribed QoS.
If this keyword is disabled, the SGSN accepts the QoS in Create PDP Context Response and Update PDP
Context Response as the Negotiated QoS (this QoS may be downgraded by the RNC in case of UMTS
access).

“Upgrade QoS Supported” flag within the common flags IE in Tunnel management messages, Create PDP
Context Request and Update PDP Context Request messages. The SGSN accepts the QoS from GGSN in
Create PDP Context Response, Update PDP Context Request/Response messages as the Negotiated QoS for
the PDP session.
