Problem:
Some Operator Service functions will not be properly applied in a Wireless
Number Portability environment.
Description:
Alternately billed calls (collect, third number, etc) are, typically,
blocked when the bill-to number is a wireless telephone number.  Operator
service providers perform queries on the NPA-NXX of the bill-to number to
determine if that number is wireless.

In a full LNP environment (porting for wireless as well as wireline) this
procedure will no longer work since wireline numbers can be ported to
wireless service and vice versa.  This can result in alternately billed
calls being allowed for wireline numbers that have been ported to wireless
service as well as alternately billed calls being blocked for wireless
numbers that have been ported to wireline service.
Frequency:  More than 5 times a month

Regions Impacted:
ALL

Rationale why existing process is deficient:
With Wireless Number Portability, the type of service that a particular
customer has will no longer be able to be identified by the NPA-NXX of the
telephone number.

Identify action take in other committees / forums:
This issue is being worked in the Message Processing Committee at OBF.  A
contribution from the National LIDB Product Team was submitted and discussed
at OBF #73.  This only addressed datya in LIDB, not the procedures of operator service providers.

Any other descriptive items:

Suggested Resolution:

Operator Service providers need to be notified of these pending problems and
take steps to avoid them.  One possible solution would be to launch an NP-DB
query to determine if the telephone number had been ported.  The second
query to the NPA-NXX data base could then be launched on the NPA-NXX of the
LRN, if one was returned, or by the NPA-NXX of the directory number if no
