GGSN Changes in Release 16
GGSN Enhancements for 16.0 ▀
Release Change Reference, StarOS Release 16 ▄
155
New Behavior: A new CLI has been introduced which configures GGSN to decode invalid MCC-MNC in ULI into
hexadecimal digits. When this new CLI is disabled, the previous behavior is in effect. The received MCC-MNC is
decoded assuming that, it contains decimal digits only. When the CLI is enabled, if the received MCC-MNC is valid, it
is decoded into decimal digits. If the received MCC-MNC is invalid, all digits are decoded into hexadecimal digits,
including filler digits, if any.

Customer Impact: Handles invalid MCC-MNC received in GTPC ULI gracefully. The invalid value is decoded into
hexadecimal digits. The Rf and Gx AVP “3GPP-SGSN-MCC-MNC” contains the decoded hexadecimal digits.

CSCug41145 - QoS eARP - H & M configuration on GGSN/PGW
Feature Changes
Configuration Support for ARP Mapping
Previous Behavior: Earlier ARP and Priority-Level AVP used to be derived on the basis of H =3 and M=8. Also if
support-earp
CLI was configured in a GGSN service earlier and if a UPC Request came without eARP IE from
SGSN that has indicated its support in CPC, request used to get rejected.
New Behavior: Now with the support of configurable H & M values, ARP and Priority-Level AVP depends on range
of H and M. Also, UPC/Sec CPC will not get rejected.
