MEID and EUIMID Migration 1 MEID and EUIMID Migration 1 1 Executive Summary 2 3 • Issue. The recent (September 2007) TIA ESN Report predicts that ESN 4 manufacturer code address space for handsets will exhaust by Q1 2008. The 5 UIMID manufacturer code space for R-UIMs (a subset of the same resource) will 6 also exhaust. In fact, UIMID assignments are continuing only because the ESN 7 administrator has been able to continue to reclaim codes from older technologies 8 (AMPS analog and TDMA digital) and transfer them to the UIMID administrator. ® 9 • Industry Response. In response to these events, the cdma2000 industry is 10 migrating handsets from ESN to MEID-based addressing, and R-UIMs from 11 UIMID- to EUIMID-based addressing. 12 o Non-unique values, known as pESN (pseudo-ESN) or pUIMID 13 (pseudo-UIMID), will be used in ESN/UIMID fields, previously 14 depended upon to be unique 15 • Potential Impact. If there are no steps taken in the network and back-end 16 systems to accommodate this change, possible impacts include: 17 o Crosstalk, interference and dropped calls 18 o Misaddressed air interface messaging (e.g. SMS received by wrong 19 user) 20 o Inability to provision and/or bill some subscribers 21 o Spurious Fraud Detection alerts 22 • Migration Status. The migrations have already started ® 23 o Several major cdma2000 operators have already upgraded their 24 network and deployed MEID-based handsets 25 o EUIMID-based R-UIMs have already been deployed by at least one 26 major R-UIM vendor ® 27 • Recommended Actions. All cdma2000 operators are recommended to 28 o Upgrade their network to support C.S0072 to minimize PLCM collisions 29 o Remove any requirement in their back-end systems for a unique 30 ESN/UIMID value 31 o Use MEID-equipped devices 32 o Choose either Long or Short EUIMID format and provision in all new R- 33 UIMs ii MEID and EUIMID Migration 1 Contents 2 1 Executive Summary
