CSCtr31994 - [S4-SGSN] RIM message should be supported over S16 and S3
interface
Feature Changes
RIM over S3 and S16 Interfaces
RAN Information Management (RIM) procedures facilitate the exchange of information between two BSC/RNC in
support of Network Assisted Cell Change (NACC) across cells which are not part of the same BSC/RNC. Network
assisted cell change improves the user experience during cell re-selection by reducing service outage duration.

Previous Behavior: The SGSN currently supports RIM over GTPv1.
New Behavior: In an MPC/EPC network, NACC is needed for transfer of radio context to target nodes during CSFB so
that the CSFB call handovers are quick. For the S4-SGSN, RIM and NACC support now extend to the S3 and S16
interfaces using GTPv2 protocol by default. This functionality requires the SGSN S3/S4 license.
