▄ Release Change Reference, StarOS Release 16

CSCum75843 - Experimental Result code 5142 is populated in Result Code

AVP

Applicable Products: GGSN, P-GW

Feature Changes

Parsing QCI Error Code in Experimental-Result-Code AVP

Previous Behavior: When QCI value was incorrect, the error code (5142) was reported in Result-Code AVP. This
behavior is not in compliance with 3GPP specification.

New Behavior: When an incorrect QCI value is detected, the error code (5142) is now encoded and sent in
Experimental-Result-Code AVP instead of Result-Code AVP.

CSCum88821 - Sig11: PC: [f7e37944/X] libc.so.6/__strncmp_sse4_2()

Applicable Products: GGSN, P-GW

Feature Changes

Error Logs in

show configuration errors

Command

Previous Behavior: No configuration errors or warning messages were displayed in the output of

show

configuration errors

command when the same Diameter endpoint is configured in multiple IMS authorization

services.

New Behavior: In this release, error message is displayed in the output of

show configuration errors

command

when the user tries to configure an endpoint which is already configured in other IMSA service.

CSCum97722 - Unexpected resultcode value in RAA when invalid QoS is

installed in RAR.

Applicable Products: GGSN, P-GW

Feature Changes

Unexpected Result Code Value in RAA when Invalid QoS is Installed

Previous Behavior: In case of parse error in QOS-Information, the QoS-Information was completely ignored without
QCI and AMBR, and the value of Result Code in subsequent RAA was set as “DIAMETER_MISSING_AVP (5005)”.

New Behavior: When an invalid QoS is installed in RAR, the QoS-Information is still ignored and the value of result
code in RAA is not set as “DIAMETER_MISSING_AVP (5005)” but as "DIAMETER_INVALID_AVP_VALUE
(5004)".

Also, if Diameter result code is already populated with an error result code, then this will not be overwritten.
