NENA Offers Clarity on NG-911 Standards

National Emergency Number Association representatives met with FCC Public Safety Bureau staff on the group’s i3 standard and an ATIS standard for IP multimedia subsystems (IMS), in an attempt to offer clarity, said a filing posted Friday in docket 21-479. “There is some confusion with respect” to next-generation 911 standards, NENA said. “The IMS911 specification, ATIS 0500036, implements the NENA i3 standard in an existing IMS … system,” the group said: “It is a standard targeted towards existing IMS systems to offer i3 based NG9-1-1 services over their existing network. IMS911 and NENA i3 are complementary, and not competing, specifications and systems implementing them are expected to be fully interoperable.” NENA said all known NG-911 systems in the U.S. are using only the i3 standard at this point.
