GGSN Feature Changes
as of May 31, 2013
This section
provides information on GGSN feature changes in release 14.0.
IMPORTANT:
For more information
regarding features in this section, refer to the GGSN Administration
Guide for this release.
New GGSN Features
This section identifies
GGSN features added/enhanced in release 14.0.
CLI Control for
NRUPC
Previous Behavior:
Need CLI to control NRUPCs required to be initiated because of NQN
and upgrade QoS flags from common flags IE.
New Behavior: CLI
introduced to suppress NRUPC in GGSN service.
Modified GGSN Features
This section
identifies GGSN features modified in release 14.0 and contains two
types of modifications: enhancements and behavior changes. Feature
enhancements are modifications based on customer change requests.
Feature behavior changes are modifications based on software error
corrections (bug fixes) that result in a change in the behavior
of the feature.
Evolved ARP (eARP)
support at GGSN
Previous Behavior:
Evolved ARP support was enabled by default. Therefore if SGSN supported
eARP and sent it in GTPv1 Create Message, GGSN used this eARP value
for setting up the bearer.
New Behavior: With
this enhancement, the evolved ARP support is now disabled at GGSN
by default. User now needs to enable this support with the new CLI
after confirming that all the home/foreign SGSNs fully
support the evolved ARP. Whenever this CLI configuration is done
to change EARP support at GGSN, existing bearer can get impacted.
No/less impact is expected on existing bearers where eARP
support was earlier disabled and later enabled with CLI. However,
If EARP support on GGSN is enabled earlier and is disabled with
this CLI then it is recommended that the CLI change is done after
clearing all the existing calls during the maintenance window.
Refer the GGSN Configuration
Management Changes for the new CLI.
RADIUS-returned Charging
Characteristics support at GGSN
Previous Behavior:
Before this change, if the Radius-returned Charging Characteristic
value was zero, by default it used to be replaced with CC value
8.
New Behavior: After
the CLI enhancement with the keyword accept-invalid,
the system will accept Radius-returned CC values always without
change, however the default behavior would remain as earlier Gx-returned Charging
Characteristics are under CLI control and by default this functionality
is disabled.
IMPORTANT:
In case the Radius-returned
is configured with accept-invalid,
then if the Radius-returned CC value is with profile index as zero,
this zero is replaced with the default value as 8, otherwise CC
is used as received from the RADIUS server.
Gx-returned Charging
Characteristics support at GGSN
Previous Behavior:
Before this change, Gx-returned Charging Characteristics were accepted
by default. There was no CLI control to enable or disable this functionality.
By default, if Gx-Returned Charging Characteristics had profile
index bits as zero, those bits were replaced with default profile
index value 8.
New Behavior: After
the CLI enhancement, Gx-returned Charging Characteristics are under
CLI control and by default this functionality is disabled.
GGSN Command Changes
as of May 31, 2013
This section
provides information on GGSN command changes in release 14.0.
IMPORTANT:
For more information
regarding commands in this section, refer to the Command Line Interface
Reference for this release.
New GGSN Commands
This section
identifies new GGSN commands available in release 14.0.
gtpc suppress-nrupc
This command enables
and disables NRUPC suppression on CPC for QoS change.
config
context <context_name>
ggsn-service <ggsn-svc>
[no] gtpc suppress-nrupc { cpc | upc } qos-change
end
gtpc support-earp
This command has been
added to enable the Evolved ARP support for GGSN service on Gn interface.
Changing EARP support for GGSN service can impact existing bearers.
By default E-ARP support is disabled. In other words, changing the
eARP support status from ‘disable’ (default) to ‘enable’ will
have less or no impact on existing calls whereas changing the eARP support
status from ‘enable’ to ‘disable’ will
have more impact on existing calls.
config
context context_name
ggsn-service service_name
gtpc
support-earp <variable>
[ default | no ] gtpc
support-earp
end
Modified GGSN Commands
This section
identifies modified GGSN commands available in release 14.0.
cc-sgsn
This command specifies
the GGSN’s source for charging characteristics (CC) - those configured
locally or those received from the SGSN.
With the enhancement
in this command by adding Gx-returned keyword,
the Gx returned charging characteristics have now become CLI controlled
and now-onwards this functionality is disabled by default.
config
context context_name
apn apn_name
cc-sgsn { use-GGSN
behavior bits profile index[ 0...15 ] [ radius-returned { { accept-invalid | replace-invalid } ] | [ gx-returned { accept-invalid | replace-invalid } ] }
no cc-sgsn { { radius-returned | home-subscriber-use-GGSN | roaming-subscriber-use-GGSN | visiting-subscriber-use-GGSN } + | [ use-GGSN ] [ radius-returned { accept-invalid | replace-invalid } ] | [ gx-returned { accept-invalid | replace-invalid } ] }
If Gx-returned with accept-invalid is
configured, then even if PCRF-returned CC value has charging profile index
as zero, same is be used for further processing. However, if Gx-returned is
configured with replace-invalid then
if PCRF-returned charging characteristic is received with profile
index as zero, zero value will be replace with default value of
8. Otherwise Charging Characteristics would be used as received
from PCRF.

New GGSN Features
This section
identifies new GGSN features available in release 14.0.
APN-AMBR Support
The APN-AMBR (Aggregated
Maximum Bit Rate) limits the aggregated bit rate that can be expected
to be provided across all non-GBR PDP contexts/bearers
and across all PDN connections of the same APN. APN-AMBR value is
transferred over the Gn and Gx interface.
APN-AMBR is enforced
at GGSN to rate limit the traffic across all non-GBR bearers. If APN-AMBR
is not supported by SGSN in the network, GGSN derives APN-AMBR AVP
to be sent to PCRF in CCR-I from MBR of the initial PDP context
received from SGSN. When MBR of any PDP context gets changed by
SGSN, GGSN locally authorizes requested MBR unless it is higher
than APN-AMBR. In such case, GGSN can either lower the requested
MBR or reject it based on local configuration.
Traffic Policing and
Shaping
The Cisco GGSN offers
a variety of traffic conditioning and bandwidth management capabilities.
These tools enable usage controls to be applied on a per-subscriber,
per-EPS bearer or per-PDN/APN basis. It is also possible
to apply bandwidth controls on a per-APN AMBR capacity. These applications
provide the ability to inspect and maintain state for user sessions
or Service Data Flows (SDFs) within them using shallow L3/L4
analysis or high touch deep packet inspection at L7. Metering of
out-of-profile flows or sessions can result in packet discards or reducing
the DSCP marking to Best Effort priority. When traffic shaping is
enabled the GGSN enqueues the nonconforming session to the provisioned
memory limit for the user session. When the allocated memory is
exhausted, the inbound/outbound traffic for the user can
be transmitted or policed in accordance with operator provisioned policy
CDR Push Support
A new CLI command has
been added to enable sending local CDR files to a remote host. When
enabled, the CDR files under the GTPP group will be sent to the
configured remote system.
Refer to the gtpp storage-server
local file command in the Modified GGSN Configuration
Commands section in this chapter for additional information.
DHCPv6 Support
Corrected Content: This
section includes corrections to previously published content. Additional
feature details have been added.
The Dynamic Host Configuration
Protocol (DHCP) for IPv6 enables the DHCP servers to pass the configuration
parameters such as IPv6 network addresses to IPv6 nodes. It offers
the capability of allocating the reusable network addresses and
additional configuration functionality automatically.
The DHCPv6 support does
not just feature the address allocation, but also fulfills the requirements
of Network Layer IP parameters. Apart from these canonical usage
modes, DHCPv6's Prefix-Delegation (DHCP-PD) has also been standardized
by 3GPP (Rel. 10) for “network-behind-ue” scenarios.
GGSN manages IPv6 prefix life-cycle just like it manages IPv4 addresses,
thus it is responsible for allocation, renew, and release of these
prefixes during the lifetime of a call. IPv6 prefixes may be obtained
from either local-pool, AAA (RADIUS/DIAMETER) or external
DHCPv6 servers. Stateless DHCPv6 procedures are used to supply higher
layer IP parameters to the end host.
This DHCPv6 support for
GGSN covers below requirement in release 14.0:
-
RFC 3633, prefix delegation
and Stateless services (primarily via the INFORMATION-REQUEST) mechanism
-
RFC 2132, DHCP Options
and BOOTP Vendor Extensions
-
RFC 4039, Rapid Commit
Support
This feature encompasses
a number of CLI command changes. Refer to the New, Modified, and
Deprecated GGSN Configuration Commands sections in this chapter
for additional information.
Dual-stack IP Addresses
Omitted Content: This
change occurred in the June 29, 2012 code drop but was omitted from
this document until now.
This feature adds support
for dual stack user layer and the dual address bearer flag on the
Gn interface on the GGSN/P-GW. During inter-RAT mobility
between 4G and 3G/2G, an EPS bearer with PDN type IPv4v6
is mapped one-to-one to PDP type IPv4v6.
Dynamic GTP Echo
Timer
The dynamic echo timer
has been added in this release to enable the GGSN and GTP-U services
to better manage GTP paths during network congestion. As opposed
to the default echo timer, which uses fixed intervals and retransmission
timers, the dynamic echo timer uses a calculated round trip timer
(RTT) that is generated once a full request/response procedure
has completed. A multiplier can be added to the calculation for
additional support during congestion periods.
This feature encompasses
a number of command changes. Refer to the New, Modified and Deprecated,
GGSN Commands sections in this chapter for additional information.
IMS Emergency Session
Support
Emergency bearer services
are provided to support IMS emergency sessions. Emergency bearer
services are functionalities provided by the serving network when
the network is configured to support emergency services. These services
are provided to normal attached UEs and depending on local regulation,
to UEs that are in limited service state. Receiving emergency services
in limited service state does not require a subscription. Depending
on local regulation and an operator's policy, the SGSN may allow
or reject an emergency attach request for UEs in limited service
state.
Following four different
behaviors of emergency bearer support are included:
-
Valid UEs Only: No limited
service state UEs are supported in the network. Only normal UEs
that have a valid subscription, are authenticated and authorized
for PS service in the attached location are allowed. It is not expected
that a normal UE would perform an emergency attach. Normal UEs should
be attached to the network and then perform a PDN Connection Request
when an IMS emergency session is detected by the UE.
-
Authenticated UEs Only:
These UEs must have a valid IMSI. These UEs are authenticated and
may be in limited service state due to being in a location that
they are restricted from service. A UE that cannot be authenticated
will be rejected.
-
IMSI Required, Authentication
Optional: These UEs must have an IMSI. If authentication fails,
the UE is granted access and the unauthenticated IMSI retained in
the network for recording purposes. The IMEI is used in the network
as the UE identifier. IMEI only UEs will be rejected (e.g., UICCless
UEs).
-
All UEs: Along with
authenticated UEs, this includes UEs with an IMSI that cannot be authenticated
and UEs with only an IMEI. If an unauthenticated IMSI is provided
by the UE, the unauthenticated IMSI is retained in the network for
recording purposes. The IMEI is used in the network to identify
the UE.
Support of ULI/RAI
Generation
User Location Information
and Routing Area Identity (ULI/RAI) IEs in Create PDP Context Request
message identify the Location Area for the UE. This information
is passed on the interfaces like Gx, Gy, and Ga. There are circumstances
when this information (ULI/RAI) does not come from SGSN,
but it has to be relayed on these interfaces.
Release 14.0 onwards,
the support has been provided to generate ULI/RAI based
on certain CLI configurations on GGSN if it has not come from SGSN.
User Location Change
Reporting Support
The user information
change reporting is enabled on GGSN via PCRF using GPRS specific event
triggers and GPRS specific credit re-authorization triggers. The
user information to be reported include Location Change Reporting
(ULI) and Closed Subscriber Group Information Change reporting (UCI).
For Location change
reporting for a subscriber session requested by GGSN, the SGSN includes
the User Location Information (ULI) if the MS is located in a RAT
Type of GERAN, UTRAN or GAN. It also includes the CGI, SAI or RAI
depending on whether the MS is in a cell, a service or a routing
area respectively. The SGSN may optionally include the User Location Information
for other RAT Types.
Closed Subscriber Group
(CSG) identifies a group of subscribers who are permitted to access
one or more CSG cells of the PLMN as a member of the CSG. A CSG
ID is a unique identifier within the scope of PLMN which identifies
a CSG in the PLMN associated with a CSG cell or group of CSG cells.
For CSG info change reporting for a subscriber session requested
by GGSN, the SGSN includes the User CSG Information if the MS is
located in the CSG cell or the hybrid cell.
Modified GGSN Features
This section
identifies GGSN features modified in release 14.0 and contains two
types of modifications: enhancements and behavior changes. Feature
enhancements are modifications based on customer change requests.
Feature behavior changes are modifications based on software error
corrections (bug fixes) that result in a change in the behavior
of the feature.
APN Enhancement
Omitted Content: This
change occurred in the June 29, 2012 code drop but was omitted from
this document until now.
Support for 2048 APNs
and Virtual APNs per chassis.
Previous Behavior:
Up to 1024 APNs can be configured on the GGSN.
New Behavior: Up
to 2048 APNs can be configured on the GGSN.
Incorrect RAT and
Missing ULI in Acct-stop for Failed Gn-Gp Handoff
Previous Behavior:
GTPv2 User Location Information (ULI) and GTPv2 RAT Type information
during the PGW-GGSN handoff was retained.
New Behavior: GTPv2
ULI and GTPv2 RAT Type information during PGW-GGSN handoff is now
discarded, and before the call processing this information is transferred
to GGSN.
IP Pool Optimization
Omitted Content: This
change occurred in the June 29, 2012 code drop but was omitted from
this document until now.
This feature allows
utilizing a smaller IP pool internally, but advertising a larger
IP pool on external routes.
Previous Behavior:
IP pool code generates the pool route, based on the IP pool range.
New Behavior: A
new pool-route option
has been added to the ip
pool command to support this feature. When IP pool route
is configured, the default fragments are not generated/installed,
rather pool route based fragment would be created and installed
in the kernel as a route.
Refer to the ip pool command
in the Modified GGSN Configuration
Commands section in this chapter for additional information.
