SGSN Features in Release 9.0

1-37

New CLI commands have been added to the RNC configuration mode to govern the 
inclusion of the Signaling Indication IE in RANAP messages. Refer to the Command Line 
Interface Reference for information on enabling/disabling this feature.

A new command has been created to enable the operator to further control message length 
by configuring the number of 

 sent in each SGSN Init Reset Resource message.

This change will have no impact on current or future configurations as the previously coded 
system value was 250.

Refer to the RNC Configuration Mode chapter of the Command Line Interface Reference for 
additional information.

The following limits for release 9.0 have been modified in the Engineer Rules appendix of
