P-GW Feature Changes
as of May 31, 2013
This section
provides information on P-GW feature changes in release 14.0.
IMPORTANT:
For more information
regarding features in this section, refer to the Packet Data Network
Gateway Administration Guide for this release.
New P-GW Features
This section
identifies new P-GW features available in release 14.0.
Acceptance of New
QoS Value in MBR
Previous Behavior: The
P-GW would only accept QoS values from the PCRF. When the PCRF is
unreachable and the P-GW receives an upgraded QoS sent in the modify bearer
command, this new QoS is ignored.
New Behavior: A
new P-GW CLI command has been introduced to control this behavior.
By default, the P-GW will continue to only accept the QoS value
(Default-Bearer-QoS and/or APN-AMBR) from the PCRF. The
P-GW will store the PCRF-authorized QoS value and use it should
the PCRF become unreachable.
When the new CLI is
configured and the PCRF becomes unreachable, the P-GW shall accept
a new QoS update in the modify bearer command.
The egtp CLI
command has been modified to control this new functionality.
New Universal Software
PID License
Universal card types
(UMIO and UDPC) are now supported in this release for the ASR 5500 platform.
A special license that contains the correct number of universal
cards must be purchased and installed on the system. With this license
UMIOs and UDPCs can also be added to an ASR 5500 chassis that was
previously equipped with MIOs and DPCs. Refer to the latest version
of the ASR 5500 Installation Guide for descriptions of UMIO cards
and UDPCs.
For information on licensing
requirements, contact your Cisco account representative.
Modified P-GW Features
This section
identifies P-GW features modified in release 14.0.
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.
Lawful Intercept
Provisioning
Previous Behavior:
If a session is intercepted through both active-only and camp-on
trigger, the provisioning behavior was inconsistent based on the
order in which active-only and camp-on triggers were configured.
The previous behavior
prevented provisioning of camp-on and active-only intercepts for
the same session and displayed an error message regardless of the
order of configuring intercepts.
New Behavior: If
active-only intercept provisioning is attempted after camp-on for
a session, the CLI displays a success message but active-only intercept
is silently ignored.
If camp-on intercept
provisioning is attempted after active-only intercept for a session,
it is incorrectly provisioned along with camp-on.
QoS Upgraded on P-GW
Without PCRF Messaging After 3G to 4G Handover
Previous Behavior:
When PCRF is not reachable, QoS requested in Modify Bearer Command
(MBC) shall be accepted.
New Behavior: When
PCRF is not reachable and new CLI is configurd, P-GW shall ignore
any new QoS update request and retain the old authorized QoS value.
The egtp CLI
command has been modified to control this new functionality.
RADIUS-returned Charging
Characteristics Support
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.
P-GW Command Changes
as of May 31, 2013
This section
provides information on P-GW configuration 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 P-GW Commands
This section
identifies new P-GW commands available in release 14.0.
Modified P-GW Commands
This section
identifies modified P-GW commands available in release 14.0.
cc-sgsn
This command specifies
the 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.
egtp modify-bearer-cmd-negotiate-qos
This command controls
whether the P-GW will use the stored PCRF-authorized QoS value (default),
or accept a new QoS value from the modify bearer command, should
the PCRF become unreachable.
config
context context_name
pgw-service service_name
egtp modify-bearer-cmd-negotiate-qos
[ default | no ] egtp
modify-bearer-cmd-negotiate-qos
end
The modify-bearer-cmd-negotiate-qos keyword configures
the P-GW to accept the new QoS value from the modify bearer command
while the PCRF is unreachable.
no modify-bearer-cmd-negotiate-qos returns
the configuration to its default, where the P-GW ignores the new
QoS value in the modify bearer command.

Discrepancy in P-GW
Service Statistics
Previous Behavior:
Previously, P-GW sessions released by S4 SGSN were also counted
as PDNs released by MME.
New Behavior: Now,
a distinction is made based on the access technology of the session
to identify PDN sessions released by MME (4G) or S4 SGSN (2G &
3G), and appropriate counters are incremented.

New P-GW Features
This section
identifies new P-GW features available in release 14.0.
CDR Push Supported
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 P-GW Configuration
Commands section in this chapter for additional information.
Closed Subscriber
Groups Support
Corrected Content: This
section includes corrections to previously published content. The
name of this new feature in the previously published content was
Closed Subscriber Group.
The P-GW does not currently
support Closed Subscriber Groups (CSG) Information Elements (IEs)
and Call Detail Record (PGW-CDR that includes a CSG record). Refer
to Closed Subscriber
Group in the MME
Administration Guide for more information about this feature.
Collision Handling
for MBR, UBR, CBR Procedures
The collision scenario
while performing Modify-Bearer-Request, Update-Bearer-Request, and
Create-Bearer-Request procedures occur as follows. A UE which has
exhausted its quota is trying to attach. P-GW will send the PCRF
a CCR-I. PCRF sends back CCR-A. P-GW sends back Create-Session-Response.
PCRF will obtain the quota from the Balance Manager and find that
it is exhausted. PCRF will immediately initiate an RAR with new
quota to inform P-GW about the exhausted condition. P-GW initiates
Update-Bearer-Request. At S-GW, the S1-U has not moved to connected
state yet. S-GW forwards Update-Bearer-Request to MME. MMEs in the
network have been modified to support this scenario by suspending
Update-Bearer-Request processing for a while and sending Modify-Bearer-Req
to S-GW. This causes the collision at the S-GW.
With this feature,
the S-GW rejects Update-Bearer-Request from the P-GW if S1-U is
not connected. When the P-GW receives a negative Update-Bearer-Response,
it starts a timer. After timer expiry, it informs the PCRF about
the transient failure. PCRF sends RAR with the quota again. This
time Update-Bearer-Request will succeed.
Refer to the egtp command
in the New P-GW 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.
P-GW 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.
DHCPv6 support for
P-GW covers the following requirements:
-
RFC 3633, prefix delegation
and Stateless services (primarily via the INFORMATION-REQUEST) mechanism

Support
This feature encompasses
a number of CLI command changes. Refer to the New, Modified, and
Deprecated P-GW Configuration Commands sections in this chapter
for additional information.
Dual-stack IP Addresses
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 eGTP 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 CLI command changes. Refer to the New, Modified, and
Deprecated P-GW Configuration Commands sections in this chapter
for additional information.
Fair Usage Policy
per Subscriber
This feature provides
mechanisms to define and enforce Fair Usage Policy (FUP) per subscriber.
It is also known as Service-Group QoS.
This feature introduces:
-
Support for PCRF specified
volume usage monitoring key for qos-group-of-ruledefs, and PCRF
specified flow-gating for qos-group-of-ruledefs.
-
It provides a way to
define a Service-Group construct that may include unrelated services
defined on the ASR5x00.
-
It provides a mechanism
to dynamically install, and remove, pre-defined Service-Groups for
a subscriber over Gx.
-
It provides a way to
dynamically set and change QoS parameters of a Service-Group for
a subscriber over Gx using CCA and RAR messages.
-
QoS parameters of a
Service-Group are: Flow-Status, Flow-Rate and Volume threshold.
-
It allows the application
of flow-rate (maximum bit rate and burst size) to a packet flow progressively
at Service and Service-Group levels by DSCP marking the packets.
-
Flow status gating can
block, allow or redirect packets.
-
It provides the ability
to monitor the volume usage of a Group-of-Services. Multiple Group-of-Services
can share a volume quota.
-
It allows sharing configured
volume threshold of a Service-Group across all services in that
group. This sharing is dynamic, which means no predefined quota
will be allocated per service in a Service-Group.
-
Finally, it allows notification
to a PCRF in a CCR-U message when volume threshold for a Group-of-Services
is crossed.
For more information regarding
the Service-Group QOS Support feature, refer to the New ECS Features section
in the ECS Changes in
Release 14.0 chapter.
IPv4 Transport Supported
on S2a Interface (PMIPv6)
P-GW supports PMIPv6
over an IPv4 transport.
MSISDN Support in
Gx (PMIP-PGW)
PMIP P-GW now supports
receiving MSISDN in the PBU over S2a interface and making MSISDN
available over Gx/Gy/Billing/LI; MSISDN
is available on the same interface as when it is received over GTP
interface.
Refer to the mobility-option-type-value command
in the Modified P-GW
Configuration Commands section in this chapter for additional information.
PCO-Based P-CSCF
Address Discovery
One of the methods
available to a UE to obtain the P-CSCF address(es) is by P-CSCF discovery
request and provisioning of P-CSCF address(es) in the Protocol Configuration
Options (PCO) IE in the session management procedures. This method
is based on configuration of the potential P-CSCF addresses in the
GGSN or P-GW.
This feature introduces
a 128-entry table in the P-GW with one primary and one secondary P-CSCF
address in each entry. For the PCO-based P-CSCF discovery method,
an entry from this table will be returned to the UE. Entries are
served in round robin fashion. If the same address pair is repeatedly
configured in multiple entries in the table, it accomplishes the
same effect as assigning a weight to that address pair. P-CSCFs
will be served traffic in proportion to the number of entries in
which their address appears.
Modified P-GW Features
This section
identifies P-GW features modified in release 14.0. There are two
kinds of modified features: enhancements and behavior changes. Enhancements
are feature changes based on customer change requests. Behavior
changes are feature changes that modify an existing behavior and
may result from software error corrections (bug fixes).
APN Enhancement
Support for 2048 APNs
and Virtual APNs per chassis.
Previous Behavior:
Up to 1024 APNs can be configured in the P-GW.
New Behavior: Up
to 2048 APNs can be configured in the P-GW.
CC Value “0F00” Sent
from PCRF Mapped Incorrectly to Gy, Gz
Previous Behavior:
When PCRF sent CC value “0F00” in the CCA-I, it
was mapped incorrectly to Gy/Gz.
New Behavior: P-GW
now accepts CC value containing A-F hex values from PCRF. CC value
received from PCRF is transparently mapped to PGW-CDRs and other interfaces.
CCR-U with Volume
Report
Previous Behavior:
When volume report was sent while usage monitoring was still active,
the system continued with existing thresholds configured.
New Behavior: When
volume report is sent while usage monitoring is still active, the
threshold is set to infinite until response is received from PCRF.
Gx Monitoring Key
Previous Behavior:
Insignificant zeroes in the monitoring key are stripped off while
encoding/decoding it over Gx.
New Behavior: Insignificant
zeroes are not stripped off while encoding/decoding the
monitoring key AVP over Gx.
Gx Session Sync
Up Using Revalidation-Timeout AVP
PCEF(P-GW) shall sync
up Gx session with PCRF using Revalidation-Timeout AVP.
PCRF shall arm/subscribe
Event-Trigger (REVALIDATION_TIMEOUT, 22) to PCEF (P-GW)
and provide Revalidation-Time AVP.
P-GW shall request policy
update by sending Credit-Control-Request Update when revalidation
time expires.
IMSA Flow Description
Previous Behavior:
When flow descriptions of protocol 50 were installed in dynamic
rules, PCEF rejected rule installation.
New Behavior: Rules
with flow descriptions of protocol 50 now supported in PCEF and
such rules are successfully installed.
IMSA SGx Module
Implementations
Previous Behavior 1:
When call is cleared, CCR-U was sent for each bearer with bearer-operation
as TERMINATION and CCR-T sent for last bearer (with bearer-id/bearer-op AVPs).
New Behavior 1:
While clearing the call, CCR-Us won't be sent to PCRF for secondary
bearers. Only single CCR-T will be sent without bearer-id.
Previous Behavior 2:
IMSA used to detect immediate failure before sending RAA, like unknown_bearer_id,
rule-failures.
New Behavior 2:
RAA will always be sent with success. Another CCR-U will be generated
to report failures and rule(s) status.
Previous Behavior 3:
A few statistics were printed at IMSA session (bearer level).
New Behavior 3:
Statistics now printed at control session level (subscriber level).
IP Pool Optimization
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 P-GW Configuration
Commands section in this chapter for additional information.
L2TP Tunneling Enhancement
The following scenarios
have been confirmed:
-
Overlapping IP addresses
inside an L2TP tunnel are supported; operators allowed to not define
local IP pools in case of L2TP tunneling in conjunction with a specific APN.
-
Multiple L2TP tunneling
destinations and tunnel load balancing supported.
S6b
Previous Behavior:
Auth-App-Id was sent as 16777999 under CER/AAA messages
for S6b-standard, as well as S6b-Custom dictionary.
New Behavior: Auth-App-Id
will be sent as 16777272 for s6b-standard dictionary.
Usage Report Sent
During RAT-Change
When an Inter-RAT handover
happens, P-GW shall send CCR (UPDATE_REQUEST) to PCRF with
Event-Trigger AVP setting to USAGE_REPORT and RAT_CHANGE
together with Usage-Monitoring-Information.
CLI command event-update has
been expanded to customize sending of Usage-Monitoring-Information
based on specific event triggers.
