  1. Mobile network evolutionIntroduction of IP in 3G WCDMA RAN Quoc-Thinh Nguyen-Vuong nvqthinh@vntelecom.org

  2. Agenda • Market & Technology trend • Introduction of IP in 3G/LTE solution • China Unicom: 3G HSPA deployment

  3. 1 Market & Technology trend

  4. Mobile telecom market trend • Data revenues per user increase • Data revenues per Mbit decrease -> Cost per Mbit MUST decreases

  5. SDH Evolution Path ASON (ROADM & PXC) ASTN & OTN (MSTP) Wireless Access Evolution Path Native Ethernet Evolution Path Radio Access Networks SDH & WDM (Digital Cross Connect) T-MPLS Sync.

  11. PSTN GGSN CS-MGW CS-MGW SGSN 3G UMTS R99 to 3G R4: All-IP core network • Optimized networks for voice and data • Service integration requires unified network • no difference between media (voice, data, video) • no media dependent calls, but media independent sessions • Easier to manage GSM BSS GSMBTS GSMBSC A MS Nc GMSC Server MSC Server Um Abis GSMBTS GSMBSC Mc Iu-CS Gb Nb IP Iub Node B RNC Gi Gn Uu Internet Iur UE Iu-PS Iub Node B RNC UTRAN

  12. PSTN GGSN CS-MGW CS-MGW SGSN 3G UMTS R99 to 3G R5: HSDPA+IP in UTRAN • Key enhancements • Introduction of IMS • Introduction of IP transport option in UTRAN (Iub, Iur, IU-Ps, and Iu-Cs) • Introduction of HSDPA GSM BSS GSMBTS GSMBSC A MS Nc GMSC Server MSC Server Um Abis GSMBTS GSMBSC Mc Gb Nb Iu-CS/IP IP Iub/IP Node B RNC Gi Gn Uu Internet IMS Iur/IP UE Iu-PS/IP Iub/IP Node B RNC UTRAN

  14. 2009 2010 2008 2011 2012 2013+ W-CDMA Markets views Summary Data growth HSDPA - HSUPA performance Advanced HSPA+ features HSPA accelerating data adoption HSPA+ aligned with full HSPA+ ecosystem ramp up HSPA+ enhancements HSPA+ introduction IP transport IP interface addressing Packet data traffic Step by Step approach : Smooth E2E evolution towards full IP of transport architecture IP interfaces customization & optimization Full IP transport Voice over HSPA CS Voice over HSPA+ as a first step. VoIP over HSPA+ and LTE will be deployed in a convergence step Utran sharing UMTS 900Mhz Utran Sharing MOCN

  15. Benefit of IP transport migration • Few full IP network planned / in deployment • Smooth E2E evolution towards full IP of transport architecture • Stepped approach addressing first data traffic growth with IuPS over IP & Hybrid Iub • Migrate all interfaces (Iub, Iu-CS, Iur) to IP in a second step. MARKET VIEW • E2E QoS & reliability: • Guaranteed thanks to MPLS/IP/Ethernet • CAPEX & OPEX savings: • IP/Ethernet cost efficiency • IP-based UTRAN cost is much less than ATM-based UTRAN • Pseudo-wire is used to transport ATM over IP (one IP backbone) • Prepares mobile operators effectively for a future evolution to native IP in the mobile network (HSPA+, LTE solution) • Single IP network for the Transport Plane, the Control Plane, and the Operations and Maintenance Plane BENEFITS

  16. 3 China Unicom: 3G HSPA deployment

  17. China’s telecom market overview

  18. China Unicom: 3rd largest mobile operator in the world • 3G in China : Three licenses • China Mobile: TD-SCDMA • China Telecom: Pursue CDMA2000 EV-DO path (howeverchoose LTE for 4G) • China Unicom: Choose 3G WCDMA • WCDMA vendor: Alcatel-Lucent, in fact Alcatel Shanghai Bell (ASB) • WCDMA HSxPA product: last version with hybrid Iub & Iu-PS over IP • Core network: Huawei’s MSTP solution Mobile business market share Fixed business market share

  19. How can the ALU win the contract? • Procurement: ALU (ASB), Ericsson, Huawei, ZTE • Each vendor did a trial  China Unicom then made a choice • To win this contract, ALU must propose very low price (the same as the one proposed by Huawei) • Consider the gain for the long term and from the support • The following steps were taken to secure the deal ….. • Persuade customers • Lobby customers • Set reasonable price • No ASB, ALU cannot win the contract due to political issue (local vendor)
