Numbering Interact E. 164 Mobile NDC - Subs Number ABC(D)- X 1 X 2 X 3 X 4…… IMS 2. 4. 5. 5. 6. 2. e 164. arpa Enum MGCF NDC - Subs Number AB(C)-DEF(G) X 1 X 2 X 3 X 4 ? ? ? PSTN FWA * Media Gateway Controller Function

Numbering Allocation & Characteristics • IMS : enum, ? ? ? etc Mobile : NDC + SN , max 11/12 Digit = 10 Billion/ndc High usage to get 1 customer recycle process • PSTN/FWA : NDC + SN , max 9/10 Digit = 1/10 Billion each area code max 80 Billion ( 2 Digits ) , 8 Million ( 3 Digits ) middle usage to get 1 customer ( FWA Only) recycle process

Transition PSTN. FWA. Mobile PSTN. Mobile. NGN (FWA) FWA has similar marketing method like mobile FWA & Mobile may have same pattern for customer habit (pre Paid) FWA has numbering problem for transition

Alternative 1. NDC + SN ( + 1 Digit at new block allocation ) 2. NDC + Operator Code + SN NDC - Subs Number AB(C) – D - X 1 X 2 X 3 X 4 X 5 X 6 X 7 NDC - Subs Number AB(C)-DEF(G) X 1 X 2 X 3 X 4 X 5 PSTN FWA

Comparison Operator Code Symmetric Regulation Easy Routing Huge Allocation Equal Treatment Customer Socialization +1 Digit Asymmetric Regulation Usual Routing Partial Allocation Partial Customer Friendly

Question • Other Alternative E. 164 • NGN Without Enum
