Command Changes
qos allow-upgrade access-type
This command is ued to configure support for QoS upgrade from GGSN/PCRF:
config
apn-profile <profile_name>
qos allow-upgrade access-type { gprs | umts }[ prefer-as-cap subscription ]
remove qos allow-upgrade access-type { gprs | umts }
exit
Notes:
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”
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”
If keyword
prefer-as-cap subscription
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).
