Use existing CLI to enable this functionality, use the
ran-information-management
commands in both the RNC
configuration mode and the SGSN Global configuration mode. Use of GTPv2 is determined by configuring the EGTP
service and use of GTPv1 is determined by configuring the SGTP service and then associating the EGTP or SGTP
service configuration with the SGSN service configuration and/or the GPRS service configuration.

Currently, eGTPv2 stats are not available for GTPv2 RIM messages.
Customer Impact: This feature enables faster handover, which is especially critical in CFSB scenarios for faster voice

Feature Changes
Location Change Reporting for S4-SGSN
Previous Behavior: The Gn-SGSN supports 2G and 3G location change reporting via user location information (ULI)
reporting to the GGSN.
reporting to the GGSN.
New Behavior: S4-SGSN now supports 2G and 3G location change reporting per 3GPP 29.274 release 11.b, if the P-
GW requests it and if the feature has been enabled in the configuration (see Command Changes below).
GW requests it and if the feature has been enabled in the configuration (see Command Changes below).
With this feature enhancement configured, the S4-SGSN is ready to perform ULI reporting per PDN connection via
GTPv2. Reporting only begins after the S4-SGSN receives a reporting request from the P-GW. The P-GW generates a
request based on charging enforcement and policy enforcement from the policy and charging rules function PCRF.
Location Change Reporting is configured and enabled/disabled per APN.

This feature has been further enhanced with a network sharing option. If the network sharing license is installed and if
the network sharing feature is enabled, then the operator can configure which PLMN information the SGSN sends to the
P-GW in the ULI or Serving Network IEs.

Important:
The S3/S4 license is required to enable S4 functionality. The new “Location-reporting in connected-
mode” license is required to enable Location Change Reporting functionality for the S4-SGSN. This new license is now
required for Location Change Reporting on the Gn-SGSN.
