communicates this identity with the IPMS server in the form a standalone IPMS message with IMSI TLV in it. The
different identities of MS are learned by SGSN during a call in several signaling message.

Intracer support for 2G calls re-uses the same framework implemented for 3G calls in the previous release. An increase
in the call-processing time is observed as the activities like duplicating the signaling PDU, generating the TLVs,
constructing the IPMS event and packet, and shipping it to IPMS server are done on every signaling message.

Command Changes
ipms-suppress
The new command
ipms-suppress
is configured to suppress or allow the IPMS-event reporting to Intracer for the
specified RAT. This CLI command helps the operator to change the IPMS-event reporting and manage network load or
congestion on the fly.
congestion on the fly.
configure
sgsn-global
ipms-suppress [gprs | umts]
no ipms-suppress [gprs | umts]
end
Notes:
At a time only service (either gprs or umts service) related ipms event reporting to the Intracer server (IPMS
server) can be suppressed using the CLI command, provided there is a valid IPMS-context and server address.
When
no ipms-suppress [gprs | umts]
is configured then regardless of the service provided the
suppression enabled on the service (configured through
ipms-suppress [gprs | umts]
) will be disabled.
There is no one-to-one mapping of the
ipms-suppress
and
no ipms-suppress
.
For example, if ipms-suppress on gprs is configured using the command
ipms-suppress gprs
. To remove
ipms suppress, either of the commands
no ipms-suppress gprs
or
no ipms-suppress umts
can be
used. However the command
no ipms-suppress gprs
is recommended in such a scenario.
By default the IPMS event reporting will be done by both the services, provided there is a valid IPMS-context
and IPMS-server configured.
Performance Indicator Changes
show ipms status
The show command
show ipms status [all | server address]
is executed to verify Intracer support for 2G
calls, on executing the command the following parameters are displayed:
BSSGP msg
LLC msg
2G GMM/SM msg
