Problems and Issues Management
In late 1999, the LNPA WG established a "problem identification and management process" (PIM) for LNP issues. The LNPA WG is not responsible for resolving all LNP problems. The LNPA WG does an initial evaluation of each LNP problem submitted, then either develops a resolution for the issue or refers the issue to the appropriate forum for resolution. The status of each LNP issue submitted is reported to the NANC on a regular basis.
The LNPA WG has developed issue submittal guidelines, an issue submittal form, process flows, and a tracking mechanism. Issues should be submitted to the LNPA WG, using the issue submittal form, at least two weeks before the LNPA WG meeting at which LNP issue's discussion is desired.

The LNPA-WG reached consensus on a best practice related to pass code/PIN verification (Best Practice 60). The best practice states that a provider cannot use a provider assigned pass code/PIN as validation or require the pass code/PIN to obtain a CSR. The new best practice will help in preventing unnecessary delays of porting, whether the delay is intentional or not.

In today's version of the NANC flows, both slides 1 and 2 indicate the LSR-FOC process should be used for the processing of ALL intermodal ports (both wireless and wireline). This needs to be revisited and updated to reflect the industry decision.

The Verizon Wireless Network Repair Bureau (NRB) is experiencing a marked increase in the number of trouble tickets opened for Intercarrier SMS problems related to customers who have Ported In their numbers to Verizon Wireless (VZW). These new VZW customers are unable to receive text messages from customers of the carrier they left due to the data in the Old Service Provider's system(s) not being fully deactivated or cleaned-up.
