If the AF requests the PCRF to report the Access network information, the PCRF provides the requested Access
network information indication (e.g. user location and/or user time zone information) to the PCEF within the Required-
Access-Info AVP included within the Charging-Rule-Definition AVP of an appropriate PCC rule. The PCRF also
provides the ACCESS_NETWORK_INFO_REPORT event trigger within Event-Trigger AVP (if this event trigger is
not yet set). If the ACCESS_NETWORK_INFO_REPORT event trigger is set, upon installation, modification and
removal of any PCC rule(s) containing the Required-Access-Info AVP PGW determines if it can obtain the required
location information for the used IP CAN type.

The P-GW provides the required access network information to the PCRF within the 3GPP-User-Location-Info AVP,
User-Location-Info-Time AVP (if available), and/or 3GPP-MS-Time Zone AVP as requested by the PCRF; the PGW
also provides the ACCESS_NETWORK_INFO_REPORT event trigger within the Event-Trigger AVP.
User-Location-Info-Time AVP (if available), and/or 3GPP-MS-Time Zone AVP as requested by the PCRF; the PGW
also provides the ACCESS_NETWORK_INFO_REPORT event trigger within the Event-Trigger AVP.
During bearer deactivation or a UE detach procedure, the P-GW shall provide the access network information to the
PCRF within the 3GPP-User-Location-Info AVP and information on when the UE was last known to be in that location
within User-Location-Info-Time AVP. If the PCRF requested User location info is part of the Required-Access-Info
AVP and it is not available in the P-GW, the P-GW provides the serving PLMN identifier within the 3GPP-SGSN-
MCC-MNC AVP.

The benefit of this feature is that it allows the EPC core to support an efficient way of reporting ULI and/Time-Zone
information of the subscriber to the IMS core.

CSCul17198 - [SGW] GTP echo and GTP message retry shall be configured
separately
Feature Changes
Separate Configuration for GTPC Echo and GTPC Non-Echo Messages
Previously, the GTP echo and GTP message retry timer could be configured separately, but the number of GTPC echo
requests could not. The maximum retry number now can be configured separately along similar lines as the timer
configuration.
requests could not. The maximum retry number now can be configured separately along similar lines as the timer
configuration.
Both in egtp-service and peer-profile modes, the
echo-max-retransmissions
keyword is added to allow the
separate configuration of GTPC echo retransmissions.
Previous Behavior:
max-retry
option is common for both GTPC Service Configuration Mode and Peer-Profile
Configuration modes.
New Behavior:
echo-max-retransmissions
is introduced explicitly for the configuration of echo max
retransmissions in both GTPC Service Configuration Mode and Peer-Profile Configuration Mode.
Command Changes
echo-max-retransmissions
The
echo-max-retransmissions
keyword is now available in both EGTP Service Configuration Mode and Peer
Profile Configuration Mode. This keyword is available to allow for the separate configuration of GTP echo
retransmissions in each mode.
