CSCud72320 - Allow unknown equipment on SGSN
Feature Changes
Support for Handling Unknown Equipment
Previous Behavior: In certain scenarios when EIR returns equipment status as “UNKNOWN_EQUIPMENT” in
response to CHECK_IMEI requests, SGSN returns a failure and the ATTACH/RAU does not succeed. Unknown
equipment's were not allowed in SGSN.
response to CHECK_IMEI requests, SGSN returns a failure and the ATTACH/RAU does not succeed. Unknown
equipment's were not allowed in SGSN.
New Behavior: To support unknown equipment handling in SGSN, a new CLI option
allow-unknown
has been added
in the
gmm retrieve-equipment-identity
command under the Call Control Profile configuration. Based on the
configuration of this command the SGSN either accepts or rejects the requests from unknown equipment. If this option
is configured, SGSN will ignore the “UNKNOWN_EQUIPMENT” equipment status received from EIR and will allow
the call to continue, otherwise if the keyword is not configured in cli, SGSN will reject the unknown equipment as per
its default behavior.

CSCuh75222 - SGSN to display number of HSPA subscribers
Feature Changes
High Speed Pack Access (HSPA) Subscribers Statistics Added
Previous Behavior: The SGSN does not display any statistics related to High Speed Pack Access (HSPA) subscribers.
New Behavior: The SGSN now displays the statistics of High Speed Pack Access (HSPA) subscribers. The SGSN
displays the breakdown of HSPA subscribers into different negotiated MBR ranges such as 16-32 Mbps, 32-64 Mbps,
64-128 Mbps and 128-256 Mbps. The SGSN uses the negotiated downlink MBR value to derive these statistics. This
enhancement is currently supported only on Gn SGSN for 3G or UMTS subscribers. The show command
displays the breakdown of HSPA subscribers into different negotiated MBR ranges such as 16-32 Mbps, 32-64 Mbps,
64-128 Mbps and 128-256 Mbps. The SGSN uses the negotiated downlink MBR value to derive these statistics. This
enhancement is currently supported only on Gn SGSN for 3G or UMTS subscribers. The show command
