3 Outline In addition to the current GSM/GPRS functions supported, the MD8480C GERAN test function has been greatly strengthened by adding support for functions such as EGPRS and DTM. This presentation focuses on the latest GERAN test contents supported by the MD8480C. GERAN CS * GSM DTM * PS * GPRS EGPRS GERAN Intra-RAT CS * PS * GSM GPRS EGPRS DTM * Inter-RAT UTRAN (HSPA * /W-CDMA) CS: Circuit Switch PS: Packet Switch DTM: Dual Transfer Mode, CS/PS Simultaneous Communications Mode HSPA: HSUPA/HSDPA Slide 3 Some independent commercial EGPRS services have already started but the future will require various other tests depending on the Multislot Class expansion as well as Inter-RAT tests with UTRAN (HSPA/W-CDMA). Using the all-in-one MD8480C supports various function tests for EGPRS mobile terminals as well as Inter-RAT handover tests with UTRAN. Supports Latest Multislot Class EGPRS Test - Supports latest commercial Multislot Class12 (230-Kbps data rate) services with settings for any DL/UL Time Slot configuration complying with the 3GPP standard Supports EGPRS HSPA/W-CDMA Inter-RAT Test - Supports both between in-service EGPRS cells and EGPRS W-CDMA/HSPA Inter-RAT tests Slide 4 2

4 EGPRS Test Installing throughput monitoring software in an external server supports confirmation of maximum throughput at EGPRS connection, change in maximum throughput at EGPRS HSPA/W-CDMA Inter-RAT, packet loss, etc. Data Throughput HSPA/W-CDMA Inter-RAT EGPRS Inter-RAT HSPA/W-CDMA Time Slide 5 MD8480C Specification - EGPRS - Compliant with 3GPP standard of June 2001 (Rel-99) Layer Features Specification Layer 1 Frequency Band Modulation & Coding Scheme (MCS) All Bands supported (GSM450, GSM480, GSM850, GSM900, DCS1800, PCS1900) MCS 1, 2, 3, 4 (= GMSK) MCS 5, 6, 7, 8, 9 ( = 8PSK) Slot Number Multislot class 1 to 12, 32 to 34 (Up to DL: 4/UL:4, SUM: 5) Frequency Hopping Supported Channel Combination Combination 11/13 Broadcast Channel BCCH/CCCH, PBCCH/PCCCH Layer 2, 3 ARQ Type Type 1,2 Window Size 64 to 512 Bitmap Compression Supported Bit Rate 3GPP Base Version About 230 Kbps (MCS9, 4 multislot) 3GPP Rel-99 Slide 6 3

5 DTM is an indispensable function for achieving the same services as the multicall service achieved by W-CDMA services in GSM services. By using the MD8480C, instead of just the call processing operation, the entire DTM operation anticipated by GSM and W-CDMA/GSM commercial services can be tested in the actual voice and data communications status. GERAN DTM Test DTM Test - One unit supports CS GSM DTM (CS + PS) and PS GSM DTM (CS + PS) tests within same cell and at handover - Supports DTM Multislot class11 UTRAN-GERAN DTM Test - One unit supports GSM DTM (CS + PS) W-CDMA multicall Inter-RAT test *HSPA is also supported for PS connection at W-CDMA multicall. Slide 7 DTM Test CS (GSM) GSM DTM (CS + PS) PS (W-CDMA/HSPA) UTRAN-GERAN DTM Operation CS (W-CDMA) PS (GPRS/EGPRS) W-CDMA Multicall (CS + PS) GERAN DTM Operation CS (GSM) GSM DTM (CS+PS) CS or PS PS (GPRS/EGPRS) Slide 8 4

6 MD8480C Specification - DTM - Compliant with 3GPP standard of June 2001 (Rel-99) Layer Features Specification CS/PS Frequency Same frequency for CS/PS Transmission Power CS and PS set separately Setting Layer 1 Multislot operation only supported (Single slot operation not Slot Operation available) Multislot class 5, PDCH = TN3,TCH = TN4 Slot Assignment Multislot class 9, PDCH = TN3, 4 (DL), TN4 (UL), TCH = TN5 Multislot class 11, PDCH =TN4 (DL), TN4, 5 (UL),TCH = TN3 DTM Multislot Class 5, 9, 11 Layer 2 Short L2 Header Supported Signalling Procedure Ciphering EGPRS Capability 3GPP Base Version Both CS <-> CS+PS, PS <-> PS+CS supported Only GSM, only GPRS and both GSM/GPRS supported Voice + EGPRS supported 3GPP Rel-99 Slide 9 Ciphering Test The MD8480C supports the various GSM and GPRS ciphering algorithms. Not only can the operation of each ciphering algorithm be tested independently, but it also supports ciphering operation checks for and DTM of anticipated commercial services. GSM Ciphering Algorithm: A5/1, A5/2, A5/3* GPRS Ciphering Algorithm: GEA1, GEA2, GEA3* *A5/3 and GEA3 are supported by MX848045C V5.60. Checking Ciphering Operation at GERAN - When carriers are using different ciphering algorithms, ciphering operation before and after can be verified. Checking Ciphering Operation at GERAN DTM - The GSM and GPRS ciphering algorithms at DTM operation can be verified at various combinations based on actual network settings. Slide 10 5

The SMSCB message content can be provided from various sources, such as traffic information and weather forecasts. Using the MD8480C, not only can CBS messages including information targeted at mobile users be sent, but also the 3GPPstandardized SMSCB DRX option is supported. SMSCB Message Parameter Editing - Each parameter included in CBS and Schedule messages can be freely edited based on the communication carriers specifications. Slide 12 6
