1 Deployment Scenarios

2 Agenda Early Adopter Deployment Scenarios Possible Deployment Scenarios Service Deployment Network Deployment

3 Early Adopters Their Rationale New Radio Spectrum Allocation 3G Capacity Saturation mandated in License Conditions CDMA Evolution Challenges WiMAX Evolution Challenges

4 T-Mobile Germany Spectrum FDD 2 X 10 MHz 800 MHz (Band 20) Devices -only Fixed Router Commercial Service Initially, only rural DSL-like service offering April MHz 2100 MHz HSPA 1800 MHz GSM, (future) 900 MHz GSM 800 MHz EU Digital Dividend

5 Telia Sonera Spectrum FDD 2 X 20 MHz 2600 MHz (Band 7) Devices USB Stick with /HSPA/EDGE Commercial Service December MHz 2100 MHz HSPA 1800 MHz GSM 900 MHz GSM 800 MHz EU Digital Dividend

6 NTT Docomo Spectrum FDD 2 X 5 MHz 2100 MHz (Band 1) Devices USB-stick with /HSPA Modem Card Wifi- router Commercial Service December 2010 Mostly Urban Coverage 2100 MHz HSPA, 1700 MHz HSPA 1500 MHz Japan 800 MHz HSPA

7 Verizon Wireless Spectrum FDD 2 X 10 MHz 700 MHz (Band 13) Devices USB Stick with /EVDO Smartphones (CSFB on CDMA) Commercial Service December 2010 (Launch) Q (Nationwide) 1700/2100 MHz (capacity in future) 1900 MHz CDMA 850 MHz CDMA 700 MHz (coverage)

8 Metro PCS Spectrum FDD 2 X 5 MHz or 2 X 3 MHz AWS (Band 4) and 1900 MHz (Band 2) Devices + CDMA dual chip phones Commercial Service September /2100 MHz CDMA, 1900 MHz CDMA,

9 Summary Carrier Initial Future Devices Multi-mode Support 2600 (band7) 1800 (Band 3) 800 (Band 20) 2100 (band 1) 800 (Bands 18/19) 1700 (Band 9) 1500 (Bands 11/12) 800 (band 20) 1800 (Band 3) 800 (Band 20) USB-sticks USB-sticks Modem-box HSPA, GSM HSPA, GSM None (launch) HSPA, GSM (later) 700 (band 13) AWS (Band 4) USB-sticks CDMA2000 AWS (band 4) 1900 (band 2) Dual-chip smartphones CDMA2000

10 Service Deployment Data-only services on Data-only services on with possible handover to 2G-3G Voice and data services using CSFB Voice and data services using Vo on IMS

11 SMS & Voice Service Roll-out Launch Data-only Devices Service Roll-out Smartphones Mass Market Full-range Devices Network Optimization SMS via SMSonly SGs SMS via SMSonly SGs SMS via SMSonly SGs SMS via SMSonly SGs SMS via Full- CSFB SGs Voice & SMS via Full-CSFB SGs Voice & SMS via Full-CSFB SGs Voice & SMS via Full-CSFB SGs IMS Vo with SRVCC to 2G/3G IMS Vo with SRVCC to 2G/3G IMS Vo with SRVCC to 2G/3G IMS Vo and 3G with SRVCC to 2G IMS Vo and 3G with SRVCC to 2G data-only devices require SMS connectivity for OTA activation and configuration CSFB may be required long-term to support CSFB-only inbound roamers

12 Voice Deployment Strategies 2G/3G Step 1: Spotty Coverage: CSFB across the 2G/3G coverage area 3G 2G Step 2a: Vo Launch: UMTS PS across 2G/3G coverage area 3G 2G Step 2b: Vo Launch: SR-VCC across 2G coverage area 3G 2G Step 3: Full Vo Coverage Target Solution New terminals use only Legacy terminals on legacy networks

13 Network Deployment Spectrum New spectrum dedicated to Refarming existing 2G/3G Spectrum Network Overlay Standalone Dual -2G/3G Core Network Single -2G/3G Core Network

14 Overlay Standalone Network UTRAN GERAN MSC 2G/3G SGSN GGSN HLR HSS MME PCRF enodeb S-GW P-GW IMS

15 Dual -2G/3G Core Network Option A : TS Annex D Method UTRAN GERAN Iu-PS/Gb Gr SGSN Gn HSS/HLR S6a 2G/3G MME Gn 2G/3G/ S1-MME S11 E-UTRAN S1-U S-GW S5 P-GW SGis PDN The existing 2G/3G nodes will see the /EPC nodes as other 2G/3G nodes. All adaptations for interworking are made in the /EPC side alone. Can interwork with pre-relase 8 SGSN.

16 Dual -2G/3G Core Network Option B : S4 SGSN Gr/S6d HSS/HLR 2G/3G UTRAN GERAN Iu-PS/Gb SGSN S3 S6a S4 2G/3G/ MME S1-MME S11 E-UTRAN S1-U S-GW S5 P-GW SGis PDN The S4 SGSN exposes S3 & S4 interfaces to the core. Support for direct tunelling between the RNC and S-GW (S12 IF)

17 Single -2G/3G Core Network 2G/3G UTRAN GERAN S12 Iu-PS/Gb HSS/HLR S6a 2G/3G/ MME/SGSN S1-MME E-UTRAN S1-U S11 S-GW/ P-GW/ GGSN SGis/Gi PDN Greatly simplified network, but entails a single-vendor strategy

18 Comparative Analysis Dual (Option A) Dual (Option B) Single Technical Readiness Yes Vendor-specific Vendor-specific Future Evolution No Yes Vendor-specific 2G/3G Network Upgrade No Yes Possible Impact on Vendor Strategy No Yes Yes
