GGSN Commands - Modified in Release 12.0
This section provides information on GGSN commands modified in Release 12.0.
virtual-apn
Virtual APN selection is based on configuration parameters like roaming mode, bearer 
access service etc. Three more parameters ‘cc-profile’, ‘msisdn-range’, and ‘rat-type’ are 
added based on them virtual-apn will be selected. ‘CC-profile option specifies the APN for 
charging characteristics (CC)-profile index. The APN selection will be applied to all 
subscribers that have msisdn in the configured ‘msisdn-range’. The range has lower and 
upper limit configured as ‘from’ and ‘to’ respectively. The ‘rat-type’ option configures the 
APN for rat-type (eutran, gan, geran, hspa, utran, wlan) received in the message.
Another addition is the ‘msin-range from <start_refix> to <end_prefix>’ keywords have 
been added to the MCC-MNC in this command to enable the IMSI prefix based 
prepaid/postpaid subscribers selection on GGSN. This enhancement extends the 
MCC+MNC based virtual APN selection to MCC+MNC+MSIN Range based virtual APN 
selection.
Virtual APN selection parameter ‘rat-type’ has been enhanced with the inclusion of a new 
keyword “eutran” along with the utran, geran, wlan, gan, and hspa. It is an enhanced 3GPP 
standard air interface for LTE mobile networks. Rat-type has also been included as an 
optional keyword for MCC+MNC.

authentication
This command configures the APN’s authentication parameters. A new option 
‘prefer-chap-pco’ has been added to be used along with msisdn-auth/imsi-auth parameter. 
With this option, if enabled, GGSN performs CHAP authentication if CHAP parameters are 
received in Protocol Configuration Options (PCO). However, chap username would be 
constructed as msisdn@apn / imsi@apn and chap challenge, chap response parameters 
should be used as it is from CHAP parameters received in PCO IE. If CHAP parameters are 
not received in PCO IE of CPC Request, GGSN should do normal PAP authentication with 
PAP username as msisdn@apn / imsi@apn (ignoring any PAP username if received).
