DSI Development Package for Linux - Release Notes Release 6.2.9
44
3.6 ssdm - Failure to free licenses on reset
This release corrects an error in the release of per-link licenses for the
SS7MD board when the board is reset which previously could result in
exhaustion of licenses following multiple resets of the board.
3.7 ssdm – Additional internal diagnostics
The ssdm binary includes additional diagnostic capabilities to assist with
factory diagnosis of field issues. The capabilities do not impact normal
operation and are not applicable to the user.
3.8 MAP - Maximum size of user UESBI data
To align with the MAP specification, the maximum size of UESBI data has
been reduced (from 128 to 16 octets). This affects the MAPPN_uesbi_iua and
MAPPN_uesbi_iub parameters.
3.9 MAP – Additional error codes
MAP now supports the following user error codes:
MAPUE_unknown_MSC (3)
MAPUE_no_handover_number_available (25)
MAPUE_subsequent_handover_failure (26)
MAPUE_forwarding_failed (47)
3.10 MAP - Missing mandatory parameters in user
response data
MAP now checks for missing mandatory parameters when the MAP-User
enters response data. For previous releases it was only request data that was
checked for missing mandatory parameters. The check now applies to both
request and response primitive entry using the MAP_MSG_SRV_REQ
message. Reporting of missing parameters is unchanged (from request
checking): a MAPSWE_USER_MAND_MISSING error is reported in a
MAP_MSG_ERROR_IND message and the number of the first mandatory
parameter not found is given in the parameter data.
3.11 MAP – Handling of segmented Result components
In the event that reassembly of partial response data fails (for TCAP
segmentation using TC-RESULT-NL and TC-RESULT-L messages), instead of
simply discarding the previously stored data, MAP will abort the affected
InvokeID.
If abort occurs after a TC-RESULT-NL message, U-CANCEL is sent to TCAP,
followed by MAP_CNF with a Provider error to the MAP-User and finally a U-
REJECT to TCAP. Aborts that occur after a TC-RESULT-L message will just
send the MAP_CNF message with Provider error. The Abort may be caused by
parameter format checks or exhaustion of the buffer space. Exhaustion of the
buffer space is also reported using MAPSWE_TC_RESULT_NL_TOO_BIG.
In addition this release modifies the processing of the SendParameters
service so that response data received in multiple messages (one or more TC-
RESULT-NL messages followed by a TC-RESULT-L) is correctly handled.
