Agenda – A Heuristic Approach WCDMA Tester Product Requirements � I: Lucent experience (Network Equipment) � II: Wiscom Tech experience (mobile terminal) � III-IIII:ITRI, III experience (Baseband, protocol) � V-VI: Customer experience (operators, manufacturers) WCDMA Tester Product Challenges Meet the Challenges � The fourth year SysAir venture experience SysAir Inc. 2

WCDMA Tester Product Requirements SysAir Inc. SysAir Inc. 3

Requirement I : Network Simulator is not Network Equipment! RNC BTS We can not afford Over-Engineering the product •1996-2000: WCDMA BTS and RNC Product design •80 millions annual investment from Lucent, 16 millions from DoCoMo SysAir Inc. 4

Requirement I I : Understand 3G mobile terminal Test Criteria We can not afford test mobile initially •2000-2001 of Wiscom Tech: WCDMA BB HW and air interface protocol design •10 millions investment from AMD, and Wall Street, 30 staffs •IPR acquired by INTEL SysAir Inc. 5

Requirement III: Network Simulator is much more than a UMTS/WCDMA simulation (Neither MATLAB or OPNET is a suitable product platform ) MATLAB, OPNET are good simulation tools, UE but not suitable for NB PHY, product software PHY,MAC, MAC, RLC realization DEV DEV RLC API API UE Thin NB Thin RRC RRC (34.108) (34.108) PCCH DL-CCCH BCCH-BCH PCCH UL-CCCH DL-CCCH BCCH-FACH BCCH-BCH DL-DCCH UL-CCCH Message BCCH-FACH UL-DCCH DL-DCCH encoding Message Message UL-DCCH decoding CODEC Message CODEC SysAir Inc. 6

Requirements IV: Product 1: FTA Tester for Understand Customer’s chipset and protocol needs design company and handset manufacturer CC, MM, SM, GMM SMS UT Product 2: Manufacture RRC EMMI, RLC AT coms MAC Tester for handset BMC PCO UT PDCP manufacturers TTCN test cases Product 3: Network IOT Tester for operators and UE (SUT) handset manufacturer Dc PCO AM/UM/TM PCOs RRC Direct Transfer Product 4: Application RLC PCO CRLC IOT Tester for operators, MAC PCO CMAC PHY LT handset manufacturer, and PCO CPHY ASP SysAir Inc. 7

Requirement V: Circuit Switched Application Test SysAir Inc. 8

Requirement VI: Packet Switched Application Test SysAir Inc. 9

WCDMA Tester Product Challenge for small company SysAir Inc. SysAir Inc. 10

Challenge I: 1. TTCN tool expensive 2. Test mobile expensive 3. Test Tool integration requires more resource than small company can handle Challenge II: NAS 1. ASN.1 tool expensive SIB and RRC SIB and RRC NAS CODEC 2. RRC CODEC CODEC CODEC CODEC extremely complex 3. Test SW Platform Thin RRC: UE L1C Thin RRC: NB L1C (MATLAB is too slow) (TS 34.108 Scenarios) (TS 34.108 Scenarios) Configuration Configuration CODEC: TS 34.108 CODEC: TS 34.108 CPHY, CPHY, DEV message CMAC,CRLC CMAC,CRLC compiler and DEV C DEV C editor UE PHY, API API NB PHY, MAC, RLC Test SW Platform MAC, RLC SysAir Inc. 11

Challenge III: 1. Real Cellular network is very complex, what is the suitable model for network simulator 2. Network and Application IOT provision UMTS Core NW RNC PSTN BTS IP/PDN Test log RNC BTS OA&M/ BTS RNC Call Trace DM DM Network simulator SysAir Inc. 12

Challenge IV: 1. How to build the HW? 2. FPGA Vs DSP 3. Digital I/Q, Analog I/Q, RF options 4. We can not afford to design ASIC 5. PC and embedded HW communication 6. Embedded HW and RF integration RF RF ARM DSP Memory core core GSM Multithread GSM A/D Memory DSP logic & core W-CDMA Shared W-CDMA D/A AMBA GPRS GPRS Memory DSP core HW HSDPA HSDPA Memory I/O DSP Video RAM IP core I/O SysAir Inc. 13
