Impacts / Requirements

Addressing Possible ESN Exhaust

Background

• ESN use is growing as more ANSI-41 Networks deployed

• ESN Recovery success is negligible• Monthly ESN report published by ESN

Administrator (TIA)– ESNs are first come first served basis– “Honor System” applications– Exhaust projection based on historical rate– ESN exhaust may occur as early as 1Q 2006

CDG Workshop

• CDG sponsored workshop in February

• Awareness to implications for CDMA– Affects all uses of ESNs including TDMA

/AMPS

• CDG formed Working Group to develop Requirements

CDG Working Group

• CDG Requirements document completed– CDG Document 107 Version 1.0 (3March 2005)
