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 wireless process for porting based on developing and sending a 'wireless port request' (WPR) does not collect and provide all the information that is needed to map to the wireline "local service request" (LSR). Fields that are required for wire line porting may have no relevance to wireless porting. Where the information is not available the ports fail. The LSOP committee intentionally made these fields 'optional' because of wireless number portability. Some individual ILEC business rules still require these fields.

    Outside of NANC 323 - SPID Migrations, when carriers acquire or trade markets, unexpected fallout can occur for their LNP trading partners during the time the markets are being transitioned from one SPID to the other. This fallout can be difficult to resolve, customer expectations may be set incorrectly, and general porting confusion may occur if trading partners are not informed of the changes within a reasonable time period prior to the changes taking place.

    Current wireline business practices allow carriers flexibility to set their own unique "business rules" or porting requirements and change them as often as needed. Some carriers will change their business rules as often as several times a month. These frequent changes to carrier unique requirements significantly increases porting cost, error and fall-out, and inhibits the automation of porting processes.

    The current -x object (1k Pool Block) tunable of 5 business days between the Create and Activate is too long and acts as a constraint against service providers.

    Why are all service providers required to participate in certification testing if the vendors are already completing the same testing?

    Wireless carriers are not receiving customer service records (CSRs) from all wire line network service providers when porting 'Type 1' numbers from other wireless service providers who are leasing the number. Wireless port requests do not contain the needed information to complete a wire line local service request (LSR). The CSR is required to complete the LSR and the port.
