Command Changes
qos pgw-upgrade
This command includes the new
pgw-upgrade
keyword. This configures the action to be taken when the MME
receives a QoS upgrade from P-GW for Non-GBR bearers.
configure
apn-profile profile_name
qos pgw-upgrade non-gbr { accept | reject | locally-cap }
[ remove ] qos pgw-upgrade non-gbr
end
Notes:
By default, the MME accepts the P-GW upgraded QoS values for Non-GBR bearers.
accept
: The MME will accept the P-GW upgraded QoS values.
reject
: The MME will reject the P-GW upgraded QoS values.
locally-cap
: The MME compares QCI, ARP and ARP-PVI provided by P-GW to the local values of those
parameters. If the values match, then accepts towards the PGW and use local values towards the UE/RAN for
APN-AMBR and ARP-PCI. If the values do not match, the MME rejects the P-GW upgraded QoS values.
APN-AMBR and ARP-PCI. If the values do not match, the MME rejects the P-GW upgraded QoS values.
The MME will set the sum of the APN-AMBR of all active APNs up to the value of the subscribed UE-AMBR,
subject to the UE-AMBR restriction.
In the case of an Attach Reject or PDN Connectivity Reject, the ESM failure cause “Operator determined
barring” is used and the corresponding MME statistic is incremented.
In the case of Update Bearer Request Reject, the EGTP cause “Request rejected” is used and the corresponding
EGTP statistic is incremented.
A new session disconnect reason
mme-qos-pgw-upgrade-reject(589)
has been introduced to indicate when
QoS upgrade by P-GW is rejected by the MME during initial attach. The corresponding session disconnect
reason statistics are incremented .
reason statistics are incremented .
dedicated-bearers
This new command configures the MME to either accept or reject GBR and Non-GBR dedicated bearers.
configure
apn-profile profile_name
dedicated-bearers { gbr { accept | reject } | non-gbr { accept | reject } }
[ remove ] dedicated-bearers { gbr | non-gbr }
end
