forbear on requirement that wireless carriers implement LNP by Nov. 24 in 100 largest metropolitan statistical areas. Carrier hasn’t sought delay of Nov. 24 deadline for thousand-block number pooling. Leap Wireless and state PUCs have objected to Verizon request, while large carriers have backed either delay or forbearance. Public safety groups said they were concerned only about how LNP implementation could affect E911 service. Besides 6-month LNP delay, groups last week also urged FCC to consider: (1) Requiring wireless carriers to share mobile identification number (MIN) and mobile directory number (MDN) data for 911 purposes. MIN/MDN separation in LNP context refers to network and subscriber elements of cellphone number. MIN is nondialable 10-digit number that identifies subscriber handset and plays signaling role on network. MDN is dialable 10-digit number that is customer’s phone number. (2) Requiring successful 911 testing before wireless pooling/portability implementation. Groups said that in Jan. they had urged FCC to take oversight of wireless LNP/pooling tests to include national requirement for appropriate 911 testing and have carriers provide proof of successful 911 tests before LNP implementation. “As the deadline is now 3 months closer and there has not yet been any successful intercarrier testing of wireless number portability/pooling, we reiterate our request,” groups said. They said wireless subscribers that had pooled numbers should have 911 service comparable with those with nonpooled numbers.
