DSI SS7G41 Signaling Server – SIU Mode Release Notes
Release 1.3.6
30
The TCPPN_DID parameter (value=23) is required in the following messages:
TCP_MSG_CPT_REQ, TCP_MSG_DLG_REQ, TCP_MSG_CPT_IND and
TCP_MSG_DLG_IND. It is used between a TCAP user and TCAP on the SIU.
In addition the ‘id’ field in the message header must be set to the significant
16 bits of the Dialog Id.
To support an extended dialog range for TCAP the <options> field on the
TCP_MSG_CONFIG has been extended to 32 bits and a new bit, bit 16, should
be set to use the extended addressing scheme. When the bit is set TCAP may
be configured with a dialogic range of up to 1M dialogs using the
TCP_MSG_CONFIG and TCAP_CFG_DGRP configuration command.
2.2
512 Link Equivalent Throughput
This release adds the ability to license the unit for capacities of up to 512 link
equivalents (compared with the previous maximum of 256 link equivalents).
To use this increased capacity users should purchase multiple licenses to
make up the desired throughput capacity. For example, a 256 SIU link license
and a 128 SIU link license would permit a total throughput capability of 384
link equivalents.
2.3
MAP - EPS-AuthenticationSetList data
Support for EPS-AuthenticationSetList data as used by the
SendAuthenticationInfo service has been added to the response in accordance
with the MAP specification 3GPP TS 29 002 version 9.4.0 (Release 9). Two
additional parameters have been added to the request for the same service:
numberOfRequestedAdditional-Vectors and additionalVectorsAreForEPS. The
parameters for both changes are only required for MAP-V3 Application
Contexts as defined in the specification.
2.4
MAP - UpdateGPRSLocation, CancelLocation and
PurgeMS to MAP Release 8
The implementation of the following MAP services has been extended to
support all the parameters detailed in MAP Release 8 as detailed in 3GPP TS
29.002 v8.18.0:
MAP-UPDATE-GPRS-LOCATION
MAP-CANCEL-LOCATION
MAP-PURGE-MS
2.5
SIU Based DTS Route Configuration
Prior to this release, applications on each DTS host were required to send
DTS routing requests to DTS when it detected startup or restart of the SIU.
This release optionally allows the DTS routing requests to be configured on
the SIU removing the burden from the host application.
To support configuration of DTS Routes a new config.txt configuration
command is supported, DTS_ROUTE. The syntax of this command is:
DTS_ROUTE:[NC=NC0],DRID=,HOSTID=[,SSN=][,CLSEQ=0][,OPTIONS=0][,
LABEL=];
The current configuration can be displayed using the new MMI command
CNDRP which has the following syntax:
CNDRP:[DRID=,][NC=,][HOSTID=,];
