  1. ISR Service Options and Key Considerations IRT Meeting Tampa Lokdeep Singh – lsingh@worldcell.com June 15th, 20007

  2. Agenda • ISR Solution components • Implementation Options • Key Implementation considerations • WorldCell introductions • Open Discussion

  3. Roaming GRX IIF Customer Care MMMF Handsets Fraud Managmnt Clearing SIM/RUIM ISR Challenges & Solution Components • IIF – Compliance with J038B and 3GPP2-CDMA-GPRS Roaming-X S0034 standards • GSM roaming agreements • SIM/RUIM cards • Dual-mode handsets • Data clearing and settlement • Fraud prevention • Support for home services • Customer support for GSM/GPRS • GRX connectivity*

  4. ISR Implementation Options • CDMA carrier hosted - Build your own • IIF hosted by CDMA home carrier • GSM roaming provided by a GSM Sponsor or through its own inter-standard roaming agreements • Secure SS7 connectivity to GSM networks • Hosted IIF + GSM Sponsor • IIF hosted by a roaming service provider (RSB) • GSM roaming agreements through a third party sponsor network • SS7 connectivity to GSM networks through the GSM Sponsor Network • Fully-hosted RSB • IIF hosted by a GSM carrier • GSM roaming agreements provided by the same Service provider • Service provider acts as a CDMA roaming partner to the CDMA home network

  5. CDMA hosted IIF CDMA Home NW IIF GSM Sponsor GSM Visited Network TAP3 TAP3 DCH CDMA ARP CDR Feed Solution #1: CDMA carrier-hosted - Build your own • IIF hosted by CDMA home carrier • GSM roaming provided by a GSM Sponsor or through its own inter-standard roaming agreements • Secure SS7 connectivity to GSM networks CIBER

  6. Hosted IIF CDMA Home NW IIF GSM Sponsor GSM Visited Network TAP3 TAP3 CDR Feed CDMA ARP DCH Solution #2: “Hosted IIF + GSM Sponsor” • IIF hosted by a roaming service provider • GSM roaming agreements through a third party sponsor network • SS7 connectivity to GSM networks through the GSM Sponsor Network CIBER

  7. Fully Hosted ISR Service CDMA Home NW RSB as CDMA RP IIF RSB as GSM SP GSM Visited Network TAP3 CIBER CDMA ARP DCH TAP3 Solution #3: Fully Hosted Option • IIF hosted by a GSM carrier • GSM roaming agreements provided by the same service provider • Service provider acts as a CDMA roaming partner to the CDMA home network

  8. ISR Implementation - Business Considerations Impact on existing CDMA roaming processes: • Will roaming implementation process be different from CDMA-CDMA roaming? • Daily Business processes different from CDMA roaming? • Requirements for multiple agreements (roaming, billing/clearing, inter-operability SP)? • Billing and clearing through your existing ARP? • CIBER records (Voice), CIBER 32/AAA (Data) or proprietary CDR file • Multiple price points or customized zone-based billing? • Net-settlement or Bilateral settlement? • Currency USD or Euro/Local- Currency fluctuations? • Responsibility for rejects? • Subscription fraud prevention mechanisms applicable to ISR in GSM mode? • White-label/customized offering? • Does this solution address your customer (Enterprise/Gov’t/consumer) requirements?

  9. ISR Implementation - Technical Considerations Interoperability • Compliance with J038-B and 3GPP2 X S0034 standard for CDMA-GPRS roaming • Supplementary service support, service codes • Handling of TLDN- MSRN mapping • Voice Mail Deposit, Voice Mail Retrieval and Notification Solutions • RUIM and IS751 (Use of IMSI) support • Inter-standard Data Solution • Support for MIP? • GRX connectivity required? • Leased lines or CRX connectivity? • SMS delivery solutions • Does ISR provide increased SMS delivery footprint? • SMS billing and clearing • Dual IMSI support may be important to some carriers • Maintenance and node recovery handling (URD-GSM MAP “Reset”)

  10. ISR Implementation - Technical Considerations Service • Impact on core network, existing processes, troubleshooting techniques etc. • Troubleshooting and customer care process. • One step resolution is the key • Visibility to GSM/CDMA traffic ( ANSI MAP, GSM MAP, AAA traffic) • GSM sponsor and IIF provider integrated customer care? • Fraud Prevention Mechanisms • HUR V/S CDMA Fraud NRT CDR exchange • Product Roadmap • MEID, IS751, NRTRDE support • Traffic Redirection and Selective Roaming Restriction • PRL management needed in GSM mode? GSM uses PLMN file that works very differently than PRL

  11. ISR Implementation - Technical Considerations Handset • Frequency bands ( Quad Band/Tri-band) • Support for OTA in GSM mode • Support for USSD, MN file (Voice Mail #) • Shared files in both modes (Phone book/contacts) • RUIM Support by the handset • Network Selection behavior in GSM mode- Interaction with Traffic steering if implemented

  12. WorldCell Fully-Hosted Solution Overview Fully-hosted ISR Solution isan IIF hosted by a GSM carrier, providing ALL components of the ISRservice, while preservingthe standard CDMA network interfaces, existing CDMAroaming processes, clearing and net-settlementprinciples

  13. WorldCell Fully-Hosted Solution benefits • Business Considerations: • Implementation and operations similar to CDMA roaming • Single agreement, single point of connectivity • Billing and clearing in CIBER. Net-settlement in US currency • White-label offering • Low CAPEX • Technology Considerations • Full compliance with standards and additional custom features • MIP for GPRS/EDGE roaming • Support for home services, Optimal Voice Mail deposit • Service Considerations • Centralized- fully hosted service • One step problem resolution – Integrated IIF and GSM customer care • Seamless roaming into GSM/GPRS

  14. WorldCell Fully-Hosted Solution Overview- ISR
