Agenda change: Discuss Resellers (originally scheduled for 10-11 6/8)in the place of Pooling Alternative originally scheduled for 1:30-2:45p. Bell Mobility was not able to attend the meeting until Tuesday to discuss their roaming contribution.

1:30 - 2:45 Wireless Pooling Alternative Evaluation

GTE filed a Petition for Reconsideration in the CTIA Forbearance docket.  They are challenging the FCC’s forbearance indicating that the FCC really didn’t forbear or eliminate LNP, and that they should.  

GTE indicated with Phase I and software triggers Pooling could be done.  They have a report indicating how to implement Pooling before LNP.  Determine if this is the wireless alternative.  We need to determine the provisioning impacts.  

Anne Cummins attended the West Region LOC meeting, and was asked “Why will Pooling not work with triggerless solution?”  She would like to know how to address this.

Do you need to differentiate between pooled and ported?

Discussed Jim Grasser’s contribution on Pooling.  The Wireless Service Provider must be the LERG assignee and code holder.  No other wireless service provider may own numbers out of that code (nxx).  Jim states if done this way, because queries will not have to be launched.  Steve indicates the nxx will be portable to the world, therefore resulting in launching queries.  

If company decides to be a default router, they will need to be compensated for routing.  

Criteria:
-	NPA/NXX must be marked as portable
-	Must be able to launch own queries, unless there is 7 digit translation 
Anne read from contribution on 7 digit translation with Default Routing to the ILEC Tandem.  Scenario: Mobile terminal dials the prefix in which the Ws carrier has donated 1000s block to the pool.  Ws MSC does 7 digit on the pooled NXX, which doesn’t belong to Ws switch. (7-digit – MSC has to be intelligent enough to say a given ten 1000 block does not belong to me.)  The MSC translates the 1000s block and sets up a trunk to the ILEC tandem, routes the call to the ILEC tandem.  The ILEC tandem queries the call, determines that the 1000 block has yet to be assigned.  The ILEC then routes the call to the Ws carrier for vacant code announcement.  The Ws carrier receives the call, does a 7 digit translation and routes the call back to the ILEC tandem creating a loop.  Steve mentions that if the pool administrator assigns a LRN to the pool, which would be an invalid NPA/NXX, this would stop the process instead of creating a loop.  This is technically feasible, but inefficient.  
-	Must have an LSMS
-	All providers in a pooled market (rate center) must be able to launch own queries (have LRN LNP query software loaded in all switches)

If we put 7 digit translation in place, though technically feasible, this would result in a query on release solution, which is unacceptable.	

The group decided to continue focusing on the scope of this committee.  We will not concentrate on petitions filed (GTE).  Absent of any Pooling questions or initiatives from NANC, the WNPSC will concentrate on LNP only.  

Alternative definition: The Ws service provider will donate and receive 1000 blocks non-contaminated NPANXXs from which they are the Lerg Assignee.  Non-contaminated means there are no numbers assigned to other service provider’s subscribers in that npa/nxx code. Switches must be LRN capable.  

Triggerless solution (SCP): switch does translation according to the LERG (npanxx-trunk group association) and setup trunk group, suspends the call - queries the SCP – routes the lrn to the end office – end office forwards the call.  (In other words, routing according to the lerg, but providing the lrn information)

	Provisioning Impacts (Pooling)
	
1.	Telephone Number (TN) Inventory will need to track on 7 digits
2.	Calling Party Pay – if wireline is playing msg – wireless will need to communicate the npa-nxx-l (7 digit) information.  
3.	NPA NXX based database services  (dir assistance, prepaid, LIDB)

Tuesday 6/8
8:30 - 9:45   NANC Report on Wireless Pooling Alternative

Group discussed the Wireless Pooling Alternative (draft) document.  The group determined that this document would be too detailed for the NANC.  Suggested use for backup information.  The group suggested a PowerPoint presentation approach.

			Will discuss at next month’s WNPSC Meeting.

11:00 - 11:20 NPAC Release Timeline

Marcel discussed NPAC work breakdown.  He says it would preferable to come into production not when a new release is being implemented.  From a wireless perspective, carriers would like to have two releases per year vs. one.   The first release would likely be the biggest release.  The second release would most likely include bug fixes, modifications (smaller release).
