plmnid plmn_id
The 5-6 digit PLMN-ID consists of the MCC (mobile country code) plus the MNC (mobile network code) to
identify the public land mobile network (PLMN) for a specific operator. This keyword associates a specific
PLMN with this specific SGSN operator policy.

This symbol indicates that command can be repeated to create repeated definitions.
Usage
An IMSI = maximum of 15 digits. An IMSI consists of the MCC (3 digits) + the MNC (2 or 3 digits) + the
MSIN (the remaining 10 or 9 digits depending on the length of the MNC ).
MCC and MNC are the minimum amount of information required to identify a unique operator policy with
IMSI filtering. The MCC and MNC combine uniquely to identify the country and the network operator, for
example: Cingular Wireless in the United States =
MSIN (the remaining 10 or 9 digits depending on the length of the MNC ).

To improve the granularity of call handling, an operator policy with additional IMSI filtering parameters can
be defined, to include filtering based on the MSIN, by defining a MSIN range - first (or start-of-range) MSIN
and last (or end-of-range) MSIN. The range numbers do not include the maximum allowed for the MSIN but
should include a sufficient number to enable the operator policy to filter effectively.
For the most efficient IMSI filter, the operator policy should include all of the above parameters and the
PLMN ID which defines the current location of the MS -- this parameter is particularly useful for
highlighting which calls are roaming.
And if none of the operator policies contain useful filtering information, then the default operator policy will
be applied as the information in this command is never defined for the default operator policy.
The following table will illustrate how these filtering parameters determine which operator policy will govern
a call:

The filtering selects which operator policy will be used to determine how a call is handled - the operator
policy that best matches the IMSI. So, a call with IMSI 123456789012345 PLMNID 23232 is best matched
with OpPol-6.
In most cases, the operator policy with the most information defined will be used as a combination of
PLMNID and IMSI provides the best match. But OpPol-6 won’t always be the best match. Using the table
above:
OpPol-1 is the best match for IMSI 123456789011111
OpPol-2 is the best match for IMSI 123456789099999
OpPol-5 is the best match for IMSI 123456789012345 if the PLMNID is 12344
policy that best matches the IMSI. So, a call with IMSI 123456789012345 PLMNID 23232 is best matched
with OpPol-6.
