charg-id { binary | decimal | hexadecimal }
Instructs the SGSN to take the profile index value of the charging characteristics, from the PDP subscription
record (selected during APN selection) and include the profile index value in the APN name prior to sending
out DNS queries. The operator can also specify the format (binary, decimal or hexadecimal) for the CC
information to be included.

start_digits
is an integer from 1 through 14 that identifies the position of the first digit in the
MSISDN to start the offset.
end-digits
is an integer from 2 through 15 that identifies the position of the last digit in the MSISDN
to be part of the offset.
rnc-id [ charg-id { binary | decimal | hexadecimal } ]
Instructs the SGSN to include the ID of the calling RNC in the APN DNS query string. Optionally, the profile
index value of the charging characteristics can be inserted into the APN name prior to sending out DNS
queries. As well, the operator can specify the format (binary, decimal or hexadecimal) for the CC information
to be included.
